SHEFFIELD, Other Commonwealth Territories 2 1 CONSTITUTION OF THE BOARD Partner Governments By the Commonwealth Telegraphs Agreement of 11th May 1948, the Governments of the United Kingdom, Canada, Australia, New Zealand, South Africa, India and Southern Rhodesia (the Partner Governments) agreed to establish the Commonwealth Telecommunica- tions Board for the purpose of promoting the efficiency and development of the external telecommunications services of the British Commonwealth and Empire'.
This Agreement was modified by a supplemental Agreement, the Commonwealth Telegraphs Agreement, 1963, of 25th July 1963, which made certain amendments to the original Agreement and replaced the Third Schedule to the 1948 Commonwealth Telegraphs Agreement by a new Form of Agreement between Partner Governments, the Board and National Bodies.
Since 1948 the following Commonwealth countries have adhered to the Commonwealth Telegraphs Agreement and have been admitted as Partner Governments: 1st June 1951 1st April 1961 12th March 1962 3rd April 1962 1st September 1962 30th January 1964 2nd July 1964 7th August 1964 16th September 1964 18th June 1965 26th February 1966 31st August 1966 13th October 1966 8th February 1967 Ceylon Cyprus Nigeria Ghana .. Malaya (now Malaysia) Tanganyika (now Tanzania) Jamaica Kenya .. Sierra Leone Uganda Singapore The Gambia Guyana Botswana In 1954 the Federal Government of Rhodesia and Nyasaland assumed control over the external telecommunications of Southern Rhodesia, and other Partner Governments agreed that the Federation should take the place of Southern Rhodesia.
On 31st December 1963, however, the Federation was dissolved and ceased to be a Partner Government.
Since then the former members of the Federation have been admitted as Partner Governments, as follows: Southern Rhodesia Zambia Malawi 6th October 1964 9th March 1965 29th June 1965 The Commonwealth Telegraphs Agreement, 1948, provided by Clause 10(1) that If any Partner Government ceases to be a member of the British Commonwealth and Empire that Government shall forthwith cease to be a Partner Government for the purposes of this Agreement .

GENERAL SURVEY New Partner Governments 1.


Three more Commonwealth Governments—The Gambia, Guyana and Botswana—joined the Partnership during the year by acceding to the Commonwealth Telegraphs Agreements of 1948 and 1963.

This brought the total number of Partners at 31st March 1967 to 22, viz.

Australia, Botswana, Britain, Canada, Ceylon, Cyprus, Ghana, Guyana, India, Jamaica, Kenya, Malawi, Malaysia, New Zealand, Nigeria, Rhodesia, Sierra Leone, Singapore, Tanzania, The Gambia, Uganda and Zambia.
Commonwealth Telecommunications Conference 1966 (CTC 1966) 2.

Reference was made in paragraph 20 of the Fifteenth General Report to the CTC 1966 and to the recommendations contained in its Report to Governments.

These recommendations have been progressively implemented.

3.
3.

The recommendations dealt with the following matters: (1) The future organisation of Commonwealth co-operation in telecommunications; (2) Modifications to the joint financial arrangements (First Wayleave Scheme); (3) The implications of Commonwealth use of, and participation in, satellite communications; (4) Future external circuit requirements of Commonwealth countries and consequential network development; (5) Technical assistance (telecommunications training schemes).
Some details relevant to these recommendations are given in the paragraphs below.

Future Organisation of Commonwealth Co-operation in Telecommunications 4.

The Commonwealth Telecommunications Board was set up in 1949 for the purpose of pro- moting the efficiency and development of the external telecommunications services of the Common- wealth and has functioned continuously over the ensuing years.
The Commonwealth Telecommunications Conference 1965, after considering the current situation, concluded that the Commonwealth Telecommunications Board had fulfilled and continued to fulfil a very useful function in the fostering of Commonwealth co-operation in telecommunications and in the dissemination of advice and information, but that, in view of the increase in the size and complexity of Commonwealth tele- communications and of the rapid developments in communications technology, there was a need to review the existing arrangements for collaboration.
5.

This question was subsequently studied by an Organisation Review Committee, set up by the 1965 Conference, which reported hack to the CTC 1966.

The latter Conference decided to recommend to Governments that a new Commonwealth Telecommunications Organisation should be set up and that it should absorb the functions of the Commonwealth Telecommunications Board.
The structure of the new Organisation would include: (1) Commonwealth Conferences on Telecommunications, which would normally take place at three-yearly intervals and would be governmental meetings at official level for the consideration of Commonwealth external telecommunications policies; (2) A Commonwealth Telecommunications Council, which would be a continuing body comprised of representatives from each of the participating Governments.
It would assemble from time to time as required to transact its business, which would embrace the wide range of functions concerned with close collaboration between Commonwealth countries in matters concerning their external telecommunications and the development of the Commonwealth system; (3) A Commonwealth Telecommunications Bureau, which would be located in London and permanently staffed.

It would service the Organisation and function under the control and direction of the Council.

9 6.
9 6.

With the concurrence of Commonwealth Governments action has been put in hand to establish the new Organisation outlined above.

Some time, however, will be required for the complete setting up of the new machinery and the taking over of the functions of the Commonwealth Telecommunications Board.

The Board itself has also been involved in a number of important tasks related to the process of winding up its affairs.
The objective is to complete the handover as early as possible, but, because of practical considerations, it is unlikely that the Board will be dissolved until early 1969.

During the period of co-existence of the Board and the new Organisation special arrangements to ensure full liaison will be observed.

Modifications to the First Wayleave Scheme 7.


The Commonwealth Telecommunications Board is responsible for prescribing and administering the financial arrangements between the Partner Governments (the First Wayleave Scheme).

This Scheme was introduced in 1950, and although the basic features remain, several modifications have been introduced over the years.

The 1966 Conference, after reviewing the operation of the Scheme, decided to recommend several significant changes.
Note was taken of these by the Board, which accordingly prepared, for the concurrence of Partner Governments, a revision of the definitions and procedure applicable to the Scheme for introduction from 1st April 1966.

The Implications of Commonwealth Use of, and Participation in, Satellite Communications 8.
In considering this matter the CTC 1966 reiterated the conclusion of previous Conferences, that cable and satellite systems were complementary and that, in order to obtain full operational flexibility, it was important to develop an integrated system of cables and satellites.

This, together with HF radio links, could provide a Commonwealth network which would offer an efficient service to the public.

9.
9.

The Conference recognised that effective forward planning for such a network called for full information on basic factors involving both financial and operational considerations.

Further careful study was necessary and it was proposed that this should be put in hand by the new Organisation.

Future External Circuit Requirements of Commonwealth Countries and Consequential Network Development 10.
The Conference agreed that the development of an adequate network required the continuing availability of up-to-date information on anticipated future traffic volumes and circuit needs over the various sectors, and decided that the statistical information submitted by the Board to the Conference should be up-dated as required and in due course maintained by the Council.
This would provide the basis for the preparation and progressive revision of an integrated Commonwealth plan embracing all media of telecommunications, a task that the Council should undertake.

Technical Assistance: Telecommunications Training Schemes II.

The Conference discussed a proposal by Malaysia which drew attention to the problem of training telecommunications personnel in the developing countries and suggested that some special provision to help meet expenses of trainees might be made.
In view of the general interest in training schemes the Conference recommended that Commonwealth Governments should give consideration to the Malaysian proposal so that Representatives on the Council might take it further.

The Conference also recommended that in the meantime the Board should collect from Partners details of appropriate training schemes which were open to trainees from other Partner countries.

12.
12.

Acting on this recommendation the Board has taken steps to ascertain from Governments details both of training schemes available and also of any training needs that they might have.

As information has come to hand, it has been consolidated and distributed to Governments.

Satellite Communications 13.

The commercial exploitation of satellite communications has continued to develop at great speed, alongside the provision of increasing facilities for the US Space Project Apollo.
In addition to successful operation of 'Early Bird' (now known as INTELSAT I) regular broadband circuits have been made available via an INTELSAT II satellite launched over the Pacific in January 1967.

A further INTELSAT II satellite was launched over the Atlantic in March 1967, but at present this only carries Apollo traffic.

Plans are proceeding for the next series of satellites (INTELSAT III), to be stationed over the Atlantic, Pacific and Indian Oceans.
These will provide a world-wide system with multiple access.

To work to these satellites several new earth stations have been completed and many more are planned.

14.
14.

The Commonwealth has played a growing part in these developments; and in addition to participation in the Intelsat Consortium-11 Commonwealth countries are members—and the Interim Communications Satellite Committee (ICSC) (3 Commonwealth members), a number of Common- wealth earth stations are either operational, under construction or firmly planned.
The following countries are concerned: Australia—Carnarvon (operational) and Moree (due to be operational by the end of 1967); Britain Goonhilly (operational, but second aerial under construction); Canada--Mill Village (operational); India—Aryl (planned); Ascension Island (operational); Bahrain (planned); and Hong Kong (planned).

10 Progress of the Commonwealth Comprehensive Cable Plan 15.

The SEACOM system of Commonwealth submarine telephone cables was completed during the year.
The Hong Kong/Guam section was brought into service in the middle of 1966, the Madang (New Guinea)/Cairns (Australia) section was completed in September 1966, and the Guam/Madang section in January 1967.

The whole system was opened by Her Majesty the Queen on 30th March 1967.

There now exists an all-Commonwealth high-grade telephone system extending from Malaysia via the Pacific to Britain—a total distance of some 23,000 miles.

16.
16.

As had been anticipated, the opening of SEACOM has stimulated a big increase in traffic in the Pacific area; and this has led to an early filling of all circuits in COMPAC.

Arrangements have therefore been made to instal Time Assignment Speech Interpolation (TASI) equipments at Sydney and Vancouver which will provide an extra 37 through circuits.

Further relief will follow with the introduction of satellite services.

Indian Ocean Commonwealth Cable 17.


As mentioned in paragraphs 14-16 of the Fifteenth General Report, a Conference which met in Colombo in January 1966, recommended urgent consideration by Governments of a proposed Indian Ocean Commonwealth Cable (IOCOM) linking Malaysia with Ceylon and India.

At the conclusion of the CTC 1966, a further meeting of the participants in the Colombo Conference was held in London, but it was not possible to reach a conclusion at that time.

18.
18.

In June 1966, Britain informed the Board, and the Governments represented at Colombo, that on the information available she was unable to support the IOCOM proposal.

Britain suggested, however, that before a final decision was taken a proper network plan should be drawn up of all telecommunications requirements within the Indian Ocean area.

19.

Such a plan will form part of the world-wide Commonwealth plan which the new Council is charged by the CTC 1966, to undertake.

West African Cable 20.


Arising out of recommendations of the Commonwealth Telecommunications Conference 1965, a West African Telephone Cable Committee was set up, to consider the feasibility of a telephone cable connecting West African Commonwealth countries with Britain and the rest of the Commonwealth.

(See paragraphs 18 and 19 of the Fifteenth General Report.)

21.
21.

A Meeting of interested Commonwealth countries was planned for January 1966, in Lagos, but, owing to unforeseen circumstances, the meeting had to be postponed.

However, in the meantime this matter was considered at a Meeting of the International Telecommunication Union Regional Plan Committee for Africa in Addis Ababa, which concluded that the project for a West African submarine cable should be abandoned.

Other Broadband Systems 22.


The Eastern Caribbean tropospheric scatter system referred to in paragraph 29 of the Fifteenth General Report was opened in August 1966, and the Bermuda/Tortola cable, which provides the international outlet for the system, was brought into service in September 1966.

Local radio links with other Caribbean Islands were also established during 1966/67 and an extension southwards by tropospheric scatter between Trinidad and Guyana is planned.

23.
23.

A further development of Commonwealth broadband capacity into this area will be provided when a 480/640 circuit cable between Canada and Bermuda, due for completion in 1969, is brought into service.

24.

Elsewhere in the world tropospheric scatter systems were being installed to provide high grade links from Commonwealth (operated) points.
Of these the Bahrain/Qatar (Doha) link was opened for traffic at the end of 1966 and links between Jamaica and the Cayman Islands and between Hong Kong and Taiwan were nearing completion by the end of March 1967.

Installation of the Cyprus/Crete tropospheric scatter system, which will provide a service with Greece, was in progress; and plans were proceeding for a Bahrain Dubai (Trucial States) link.

25.
25.

In November 1966, a contract was awarded for construction of a new type of transistorised submarine telephone cable between Britain and Portugal to be completed early in 1969.

This will provide 480 circuits spaced at 4 kHz or 640 circuits spaced at 3 kHz.

It will connect with a new cable to be laid between Portugal and South Africa.

Telex Services 26.

The rapid growth of telex services has continued.

Traffic has increased by some 20 per cent over 1965/66 and many new services have been opened.
These are shown in Section V. In addition, telex was introduced for the first time in the following countries: Sierra Leone, Muscat (Cable and Wireless Limited), and Dubai, Trucial States (Cable and Wireless Limited).

Even in those countries where telex has been long established (e.g.

Britain, Canada) there have been big increases in the number of subscribers.

11 27.
11 27.

The increase in trallic has necessitated the opening of additional telex circuits, particularly between London and certain other Commonwealth centres; whilst both Britain and Canada have made major extensions to their international telex switchboards.

Nevertheless, traffic growth exceeded anticipated demands, and this, coupled with manufacturing delays in the supply of equipment, gave rise to difficulties, particularly on radio routes.
This matter has been considered by the Board, and, following a study by its Traffic Study Group, recommendations for both short-term action and long- term planning were made to National Bodies.

Data Transmission Services 28.

With the increased use of computers the demand is growing, both over inland networks and external telecommunications, for high speed data transmission services.
From Britain an international service is now available to Austria, Denmark, France, the USA and West Germany; and plans are proceeding for further extensions, in particular to Australia and Canada.

Traffic 29.

As will be seen from the statistics in Section III, the volume of public telephone and telex traffic continued to rise significantly during the year.
The total telephone traffic increased by 17 per cent to 125 million paid minutes, and the telex traffic rose by 20 per cent to 70 million paid minutes.

IL STUDY GROUPS 30.

As in previous years, the Board remitted many questions which required detailed examination to its Study Groups.

The composition of these Study Groups is given on page 6 of this Report.

Some notes on their work during the past year are given in the following paragraphs.

Finance and Rates Study Group 31.


The Finance and Rates Study Group held 21 meetings during 1966...67.

It was actively engaged throughout the year in dealing with a variety of financial and rate matters remitted to it by the Board.

32.

Principal among these was the preparation of revised definitions and procedure of the First Wayleave Scheme, which involved lengthy and meticulous work.
This task was necessitated by the changes, described in paragraph 7 above, in the financial arrangements, agreed at the Commonwealth Telecommunications Conference 1966.

An important consideration was the need to assist new Partner Governments in this complicated field by the issue of clear and definite 'rules'.

As an adjunct to this basic document, the Study Group initiated standard forms for traffic accounting between the National Bodies, and these are now in use.

33.
33.

Apart from its normal consideration of National Bodies' wayleave estimates and accounts and other matters relating to the First Wayleave Scheme, the Study Group carried out an examination of telex and telephone collection charges and made recommendations to the Board aimed at a greater degree of uniformity in the fixing of such charges.

Technical Study Group 34.


The Technical Study Group has maintained its interest in the technical aspects of the develop- ment of National Bodies' systems and any other technical matters referred to it by the Board.

Items of particular interest were the development of tropospheric scatter systems in the Eastern Caribbean, Cyprus and Hong Kong, lincompex equipment, telegraph message relay systems and power supplies for remote radio relay stations.

35.
35.

The Study Group held 5 meetings during the year, and these were supplemented by visits to the London Message Relay Unit; the Mechanised Letter and Parcel Sorting Office; Leafield Radio Station; Dollis Hill Research Station; Cable Ship Mercury; and the Post Office Tower.

Traffic Study Group 36.

The Traffic Study Group continued its consideration of the trallic operational aspects of the Commonwealth telecommunications services and held 14 meetings during the year.

37.
37.

The principal subjects that came under consideration, other than routine matters, were: (1) The format aspects of telegraph mechanisation that had arisen from the Fourth Technical and Traffic Meeting.

(2) Shortage of circuits on international telex.

This study arose from a British National Body report on the telex service.

(3) Review of the CTB procedure for the provision of new services.

12 (4) Revised (up-dated) Traffic and Circuit Estimates (1970 and 1975)—at the request of the CTC 1966.
(5) Review of CTB monthly, quarterly and annual returns and publications of statistics.

III.

TECHNICAL AND TRAFFIC Telegraph Mechanisation 38.

Further progress has been made in the mechanisation of public telegraph message services, and Australia, Britain and Canada have large, fully-automatic systems planned or in process of installation.

India has completed the installation of a semi-automatic message relay distribution system in Bombay.
Cable and Wireless Limited have produced a fully-automatic telegraph message selective switching system for a maximum of 16 out-stations, which is already in operational service in the Caribbean.

39.

The Traffic Study Group's telegraph message format proposals, which dealt mainly with service messages, were submitted by India to the CCITT Study Group I Joint Working Party on Message Retransmission at the meetings held in Melbourne in September/October 1966.
The proposals were, in general, accepted and now form part of the CCITT Study Group I recommendations.

40.

As a follow up to these CCITT Study Group meetings Canada has formulated format proposals for the automation of control functions in the telegraph message retransmission network, which she proposes to submit to the CCITT.

Through the Board she has invited the comments of other National Bodies on these proposals and a number of National Bodies have already submitted their views.
Commonwealth Traffic and Circuit Estimates 41.

During the year the Board carried out the task of producing up-to-date traffic and circuit estimates of the Commonwealth.

These were submitted as a paper to the First Meeting of the new Council.

Traffic Statistics 42.

The Board prepares annual statistics of Telegraph, Telephone, Telex and Phototelegraph traffic carried on the Commonwealth telecommunications system.
These detailed statistics are published in a separate printed document and those for 1966/67 will be published as soon as they become available.

43.

The statistics cover only those services available for public traffic.

Leased telegraph and telephone circuits carry considerable traffic (and produce substantial revenue), but it is not possible to obtain statistics of the traffic carried on them.
Despite the high level of growth of telex traffic and the continuing growth of leased circuits, the public telegraph service has virtually maintained its previous upward trend.

The slight decrease of 0.2 per cent this year should be considered in conjunction with the exceptional rise of 6.7 per cent last year.

44.

Quarterly Traffic Reports giving details of the operational working of the various services are received from the National Bodies and are considered by the Board.

45.
45.

The following Tables A, B and C give a summary of the 1966/67 traffic statistics (estimated figures are used where actual figures are not yet available), together with a similar summary for 1965/66 for comparison.

13 Telegraph 46.

Distribution of telegraph traffic among the National Bodies is given in Table A.
Total telegraph traffic originated by National Bodies, and received from foreign countries and Common- wealth countries not Partners to the Commonwealth Telegraphs Agreements, for the year ended 31st March 1967, is estimated to have been 905,840,000 paid words, a decrease of 0.2 per cent on the previous year.

RATES 50.
RATES 50.

The following Tables show in terms of sterling the telegraph, telephone and telex collection rates of the Partner Governments, in relations between them and in relations with certain representative foreign countries, as at 31st March 1967.

Tables 1 and 2 set out telegraph rates per ordinary word: Tables 3 and 4, and Tables 5 and 6, set out respectively telephone and telex rates per unit call of three minutes.

The main changes in rates which have taken place during the year are described below.
51.

With effect from 6th June 1966, India devalued her currency by 36.5 per cent.

In order to minimise the financial effect on other Commonwealth Partners, India made certain increases in her local currency overseas telecommunications collection rates with effect from 17th June 1966.

At the same time she took the opportunity to rationalise the large number of differing overseas rates by the introduction of new rate patterns.

Details are given in Section V (Indian National Body's contribution).

52.
52.

With effect from 1st October 1966, overseas telegraph rates from Malawi were increased by some 40 per cent.

With few exceptions, the intra-Commonwealth telegraph rate per ordinary word now generally approximates to Is.

10d.

sterling.

53.

Also effective from 1st October 1966, telegraph collection rates from Canada were increased by 2 cents (Can.)

per ordinary word to most Commonwealth and foreign destinations.

Small increases in foreign press telegraph rates were also made.

54.
54.

Further progress was made towards the abolition of concessional rates for Government telegrams and such rates are now exceptional.

Cables.

There are approximately 105,000 nautical miles of telegraph cable in the Cable and Wireless Limited system.

The Company partly owns the telephone cables CANTAT (2,011 nautical miles), COMPAC (8,234 nautical miles) and SEACOM (7,049 nautical miles).

The Company is also part owner of 1,625 nautical miles of telephone cable between Bermuda/USA and Jamaica/USA, and is sole owner of the Bermuda/Tortola cable (902 nautical miles).

56.
56.

Telephone cables wholly or partly owned by the British Post Office include the two cables in the TAT 1 system (total length 4,536 nautical miles), the TAT 3 cable (3,518 nautical miles) and about 2,840 nautical miles of telephone cable in the English Channel and North Sea.

57.

SEACOM.

The Hong Kong—Guam section of SEACOM was successfully brought into service on the planned date (1st August).
To complete the SEACOM project the Guam—Madang (New Guinea) and Madang—Cairns (Queensland) sections were laid by CS 'Mercury' and HMTS 'Monarch', with assistance from CS 'Retriever', thus completing the ocean laying operations.

During the year terminal installations at Guam, Madang and Cairns and the overland mixed microwave and coaxial link from Cairns to Sydney were also completed.
The whole SEACOM system was brought into service at the end of March 1967, when the opening ceremony was performed by Her Majesty The Queen.

58.

Eastern Caribbean System and Tortola—Bermuda Cable.

The multi-channel tropospheric scatter system between Barbados—St.

Lucia—Antigua—Tortola was opened in August, and connected with the existing tropospheric system between Barbados and Trinidad.
Terminal equipment installation for the Bermuda—Tortola cable was completed during the year and the link officially opened in September to provide the northern outlet for the Eastern Caribbean system.

Further extensions are planned between Trinidad and Guyana, and between Antigua and Guadeloupe in conjunction with the French Administration: equipment for the latter is on order.
With the completion of this system plans have been agreed with the other parties concerned for the introduction of semi-automatic telephone working to provide direct operator-dialling facilities within the Caribbean area and into the worldwide network.

59.

Canada—Bermuda Cable (CANBER).


To provide additional capacity between Bermuda and North America, the provision of a 480/640-circuit coaxial cable system between Bermuda and Nova Scotia (in the vicinity of the Canadian Satellite Earth Station at Mill Village) has been agreed with the COTC, scheduled to come into operation during 1969.

CCGS 'John Cabot' has completed the survey of the sea-bed route, using with complete success a deep-sea camera developed by Cable and Wireless Limited.
This was of particular value in examining the sea-bed characteristics over the Nova Scotia continental shelf.

60.

Satellite Earth Stations.

The Ascension earth station for the NASA Apollo project was completed and made ready for service, as scheduled, in September 1966.

Minor teething troubles were cleared, and the station tracked and communicated via the errant INTELSAT II F.1 and subsequently with INTELSAT II F.3.

61.
61.

Preliminary planning proceeded for the provision of earth stations at Hong Kong and Bahrain.

Progress was made with site surveys.

62.

Telephone Cable and Repeater Manufacture.

During the year 769 nautical miles of lightweight coaxial cable were manufactured to complete the requirements for SEACOM, together with 91 Type U (160 circuit) repeaters and five equalisers.

63.

Cables to the Netherlands and Norway arc being manufactured for the Post Office.
Both cables, each with a capacity of 480 circuits and equipped with transistorised repeaters operating at frequencies up to 5 MHz, will be laid towards the end of 1967 and will be ready for service early- in the following year.

Supervisory facilities include the monitoring of gain and noise of each repeater.

64.
64.

The BPO in collaboration with the Companhia Portuguesa Radio Marconi has placed a contract for a submarine telephone cable of the same design and circuit capacity as the projected cables to Norway and the Netherlands, to be provided between Britain and Portugal.

The cable, expected to be in service early in 1969, will terminate at a point south of Lisbon, where a link-up will be possible with a cable being provided by the South Atlantic Cable Company (Pty) Ltd. between Portugal and South Africa.

70.
70.

Telephone traffic originating at Cable and Wireless Limited's stations during the year was 3,587,000 minutes, 26 per cent greater than in the previous year, a heavy rate of growth largely due to the introduction of further wideband facilities.

71.

Phototelegraph.

Phototelegraph traffic originating in Britain and at overseas branches of Cable and Wireless Limited during the year was 12,590 items, 19 per cent lower than in the previous year.
This reduction has no particular significance since phototelegraph traffic is very much subject to fluctuations depending upon the incidence of topical news events.

72.

Telex.

At 31st March 1967, there were 19,501 telex subscribers in Britain, an increase of 13.4 per cent since 31st March 1966.

The originated international traffic handled in London during 196667 was 33,050,000 paid minutes, an increase of 16.9 per cent over the previous year.
92.3 per cent of all international calls were dialled by the subscribers.

73.

Telex traffic originating at Cable and Wireless Limited's branches during the year was 1,164,000 minutes, 32 per cent greater than in the previous year, thus continuing and increasing the heavy growth rate of this service.

100.
100.

At 31st March 1967, there were 1,591 international telex circuits terminating in London, 1,243 to Europe and 348 beyond.

101.

In addition to new direct services, capacity on many existing routes expanded during the year, and many new interconnected services were introduced.

28 102.

Datel Service.

The international Datel 600 service was introduced on 1st November 1965, and is now available to Austria, Denmark, France and West Germany.
Negotiations for further extensions of the service are proceeding.

103.

There are now 19 customers using international Datel 600 service between Britain and the USA.

Engineering problems associated with the extension of the service to Australia and Canada are still under consideration, the main difficulty being to overcome the restriction imposed by the type of echo suppressor at present employed.
However, until the new type echo suppressors are available it may be possible to operate the service in the half duplex mode (i.e.

without backward channel) and negotiations on this basis are proceeding.

104.

Press Services.

Signal reception and transmission services continued to expand.

105.

Leased Circuits.


At 31st March 1967, there were 166 commercial leased telegraph circuits between Britain and the Continent of Europe and 245 circuits between Britain and extra-European countries, an increase since 31st March 1966 of 12.7 per cent and 15.6 per cent respectively.

108.

Capacity.

Circuit capacity for the public telegraph service was adequate.

Schedule extensions and additional channels to meet continued increased demand were provided for telex and telephone services.

109.
109.

In general, radio propagation conditions were better during 1966/67 than 1965,66, and consequently the traffic carrying capacity of many radio circuits improved.

110.

COMPAC capacity is being utilised to the maximum by the increased use of overflow working via Canada and Sydney.

Some relief is expected during the coming year when COMPAC TASI is opened.

Trans-Atlantic cable capacity is fully utilised although spare capacity is available via the INTELSAT I satellite.

111.
111.

Major Changes in Telegraph Traffic Handling.

The London Afghanistan (Kabul) circuit was converted from morse to 5-unit working in May 1966.

112.

6d.

per call reduced rate.


The corresponding dollar accounting rates are $2.5, $1.9, 84.5 and $3.3 respectively.

The sterling accounting rates with the US are now converted at $3=f1, as against the former coefficient of S4---£1 which applied since 1949.

Modernisation and Expansion of the System (a) British Post Office 120.
The number of 2-channel error-correcting multiplex terminals in use in London at 31st March 1967 were: 56 at Electra House, serving 18 routes, and 96 at Fleet Building, serving 27 routes.

121.

Storage for ARQ Systems.

A contract has been placed for a new design of character storage equipment for use with ARQ radio systems providing telex services.
These storage equipments use stored-programme principles and enable a common core assembly having a total capacity of 24,000 characters to be shared between 15 radio channels.

The use of time-shared stored-programme techniques and integrated circuit technology enables the equipment to be competitive with other known forms of storage.

Five equipments catering for a total of 75 radio circuits are being prepared.

29 122.

Cable Multiplex.


Cable multiplex equipment with a total capacity of 240 channels has been installed and has been satisfactorily tested between London and Sydney, New York and Tokyo.

The equipment, conforming to draft CCITT recommendations, caters both for telex and telegraph circuits, and some of the channels are already in use between London and Sydney and London and New York.

123.

Electronic Telegraph Relays.


A programme is in hand to replace all electro-magnetic telegraph relays in international radio and long distance cable circuits by solid state devices or mercury wetted relays.

The replacing items include proprietary designs as well as specially designed units where satis- factory commercial items are not available.

This work, now largely completed, has resulted in a substantial improvement in reliability as well as a significant reduction in maintenance.
124. International Telegraph and Telex Provision.

The London telex switchboard has been extended and the number of operating positions increased from 72 to 106 (46 cable and 60 radio).

A contract has been placed for a further extension to 154 positions, planned for completion during 1969.

125.
125.

Installation of the new inter-continental switching equipment has begun, which will extend to a number of additional countries automatic inter-continental telex service for British subscribers, including automatic recording of charging information, and will provide further automatic switching facilities for transit traffic.

The equipment will be brought into use in stages, the first towards the end of 1967, and the last stage, which provides for the new type C signalling, in mid-1968.

126.
126.

Installation of equipment at the new London Telegraph Centre at St. Botolph's House has started.

For international services 60 2-channel error correcting multiplex terminals and 40 24-circuit VFT terminals will be available in 1968, with a further 40 24-circuit terminals in 1969.

The first stage of the international telex exchange is scheduled to open in Autumn 1969.

127.

Extensions at Faraday International Exchange.


The contract to extend the link equipment to a 2 x 4 system is now well advanced.

A contract has been placed to provide equipment for Inter- continental Subscriber Dialling to North America, and a further contract will provide equipment to enable Remote Manual Boards to have direct access to the Faraday International Switching Centre.

128.

Automatic Transmission Measuring Equipment.


In May 1966 the British Post Office began the field trial of an Automatic Transmission Measuring Equipment (ATME) as part of a CCITT investigation of the equipment's suitability for the routine testing of international automatic and semi-automatic circuits.
ATME sets are required at each end of a route and measurements may be made in each direction of transmission with results, in the form of punched paper tape or teleprinter page print out, available at each end of the route.

129.

Ultimately 16 Administrations will be equipped to participate in the investigation.
For her part Britain intends to conduct the field trial on 10 European routes, including one British national route, using 10 circuits on each route, but at present testing is limited to the four routes which are fully equipped.

130.

Nov International Telephone Centres.

Building work is well advanced on the new centre in Wood Street (Central London) and should be completed by November 1967, when the installation of transmission and switching equipment will begin.
The initial installation of transmission equipment will be completed at the beginning of 1969, and the first stage of the switching equipment is scheduled to be available for service by late 1969 accommodating approximately 1,000 overseas circuits and 1,500 inland circuits.

131.

A site had been purchased and feasibility plans produced for a further London centre to be located in Upper Thames Street.

Some 200,000 sq.

ft. are likely to be available for apparatus purposes.

132.
132.

Extensions and Modifications to Radio Stations in Britain.

The installation of twelve 30 kW transmitters for point-to-point services and six 85 kW transmitters for press broadcast services, with their associated aerials and rack equipment, has been completed at the new Leafield transmitting station and the station is now in full operation.

136.

An extension of message relay facilities in London is now being planned with a view to the mechanisation of all overseas routes by 1969/70.

137.

Goonhilly Earth Station.


Goonhilly has been operating to the Early Bird satellite (now generally referred to as INTELSAT I) with marked success since the system opened to public traffic on 28th June 1965.

138.

The first satellite of the INTELSAT 11 series (provided primarily for support communications for the Apollo Project) was launched on 26th October 1966.
A faulty apogee motor caused the satellite to take a highly elliptical orbit instead of the planned synchronous equatorial orbit, but during the 30 week 20th-26th November 1966, it became visible for short periods to both Goonhilly and the West Australian earth station at Carnarvon.

A series of telephony and television tests was carried out during periods of mutual visibility and an historic transmission took place on 25th November directly linking Australia and England by live television.

139.
139.

Progress has been made during the year in preparing Goonhilly for the INTELSAT III satellite programme to establish a global system, commencing in 1968, and initially comprising three geo-stationary satellites over the Atlantic, Pacific and Indian Oceans respectively.

A contract has been placed for the construction of a second large aerial installation which will be ready during the first half of 1968 with a view to operation to INTELSAT III (Atlantic Ocean).

140.
140.

Plans have been prepared for the modification of the existing aerial installation after its release from the Atlantic service to enable operation to INTELSAT III (Indian Ocean), and by the end of 1968 Goonhilly should be able to work simultaneously to both the Atlantic Ocean and Indian Ocean INTELSAT Ills.

Research and Development (a) British Post Office 176.

Radio Receiver Development.

Delivery of the type HF transistorised self-tuning receiver has been completed.
Traffic trials have indicated that their performance is as good as earlier valve type receivers and that they can be controlled satisfactorily from a central point in the station.

Evaluation of the economics of controlling the receivers from the operating centre is in hand.

177.

Radio Telephone Systems.

Delivery has been taken of a number of `Lincompex' equipments but tests have indicated that the receive side of the equipment is temperature conscious.
This is being rectified and equipments are shortly being sent overseas for field trials.

A contract has been placed for 24 additional fully engineered equipments (MK II) and delivery is expected early in 1968.

178.

HF Aerials.

Tests on the HF log-periodic aerials showed them to operate satisfactorily at 30 kW but showed voltage breakdown at the ends of the dipoles under some adverse weather conditions (e.g.

low pressure and high humidity) when operated at 85 kW (F1).
The mechanical and electrical arrangements at these points have been redesigned and further extensive trials are in hand.

32 179.

Satellite Communications.

The development of earth station equipment has continued, particularly with a view to the requirements of the INTELSAT III programme.

Effective progress has been made in the fields of cryogenic systems, wide-band low-noise parametric amplifiers, threshold extension demodulators and wide-band high-efficiency aerial feed systems.
Long-term studies have continued embracing many aspects of communication-satellite usage, including methods of modulation for telephony systems, sound and television broadcasting and possible aeronautical applications, particularly where these aspects affect the efficiency of use of the radio frequency spectrum.

180.

Satellite Earth Station Aerials and Aerial Feeders.

The present primary feed of the Goonhilly No.


1 aerial is linearly polarized and the bandwidth is limited to about 50 MHz because of the difficulty of matching the coaxial receive aperture to free space.

The feed is being modified by fitting a smaller diameter dielectric loaded transmit waveguide; this will ease the matching problem and should enable the 500 MHz transmit and receive bandwidth requirement to be achieved.

181.
181.

It is proposed to decrease the feeder loss and system noise temperature of the Goonhilly No.

1 aerial by using a larger size of rectangular waveguide between the primary feed and the low-noise amplifier.

Development of the necessary over-size rectangular waveguide tapers and bends was commenced.

182.

The development of a d.c. beam-swing control system for the Goonhilly No.

1 aerial was completed.


This system will replace the present 400 Hz synchro system; fewer components will be required with the result that the reliability will be greatly improved.

183.

Work on the off-set cassegrain type of aerial system continued.

High efficiency will be obtained by the use of a shaped sub-reflector.

184.

Low-Noise Amplifiers.


Low-noise amplifier work has been concentrated on the design and construction of wide-band parametric amplifiers operating in the 4 GHz band, with low noise tem- peratures achieved by cooling the amplifiers with either liquid nitrogen or liquid helium.

The work is being extended to cover the use of closed-cycle refrigerators to replace the baths of liquid coolant.

Present bandwidths exceed 250 MHz, with noise temperature of about 17'K.

185.
185.

Equipment for the measurement of noise temperature to an accuracy of ± 1°K has been developed.

186.

Satellite System Studies and Associated Experimental Work.

An investigation of the inter- modulation effects produced by the transmission of 8 FDM/FM carriers through a wideband satellite travelling-wave tube operating near to saturation has been concluded.

187.

Work on an alternative multiple-access scheme for communication satellites using P.C.M.

has continued.
has continued.

The system uses time-division multiplex techniques and a baseband experiment has been successfully concluded, in which high-speed 'bursts' of digital signals have been effectively placed sequentially within a master time-frame, as would occur in practice at the satellite.

Compensation for Doppler shift and variable path delay have also been demonstrated.

Work is continuing to determine the minimum number of digits required to preface each burst.

188.
188.

To avoid lightly loaded FDM carriers in a common satellite transponder causing excessive intermodulation, and also to keep such carriers within the internationally agreed levels of received power flux density at the earth's surface, the addition of energy-dispersal signals to the baseband signal at the transmitter is being investigated.

189.

Echo-Suppressors.

The development of an echo-suppressor, suitable for circuits having long propagation times, e.g.
circuits via synchronous orbit satellites, has reached the prototype approval stage.

This echo-suppressor, designated Echo Suppressor No.

7A, will be compatible with the echo-suppressor developed by Bell Laboratories.

190.

Submarine Cable Systems.

A submarine cable system, which will be used for the Britain— Portugal cable, has been developed.

It will have a system bandwidth of 5 Mc/s, i.e.

a capacity of 480 4 kHz spaced channels or 640 3 kHz spaced channels.
The system will be equipped with transistor repeaters and will be designed to ocean cable standards.

191.

The development of a 12 MHz submarine cable system using transistor repeaters to provide a capacity of up to 1,140 4 kc s spaced circuits is in hand and will be completed by next year.

Its initial application is likely to be in new submarine cables to be provided across the North Sea.

192.

Transmission Equipment.


A complete range of frequency translating equipments for use on international circuits is under development.

In general they perform the same functions as translating equipments used on inland circuits but give increased facilities and better performance.

They include 62 type 3 kHz channel translating equipment with built-in carrier generation and 62 type 4 kHz high grade channel translating equipment with programme infusion facilities.

193.
193.

A through-group filter is being developed which will be suitable for both 3 kHz and 4 kHz spaced channel working and may, if required, be fitted with a delay equalizer.

Such through-group filters will be required to provide international group links suitable for the transmission of wideband data.

194. International Switching and Signalling.

To cater for growth in international telephone traffic an additional switching centre is required in London by early 1970.
It has been decided to use the basic 5005 Cross Bar 4-wire switching system for this purpose.

Development of the system to cater for some 2,500 international circuits employing CCITT Signalling Systems Nos.

4 and 5, and giving full (C42171) 33 international transit switching facilities as well as terminal facilities to and from the British national network, is progressing.
Semi-automatic and automatic operation will be catered for and IMC facilities and International Accounting and Traffic Analysis Equipment will be provided.

(b) Cable and Wireless Limited 195.

Message Switching Systems.

A fully automatic half-duplex polling and selective-switching system for a maximum of 16 outstations was developed and produced in four months to meet a target date set by BOAC for such a system in the Caribbean area.
It was brought into operation during the first week of February 1967 and has performed successfully since.

The design was based on electro- mechanical techniques, using the `stuntbox' switching facilities of the American Teletype Model 28 equipment.

A solid-state version of the system is now being developed; using micro-miniature integrated circuits, this version will be capable of working with any make and type of teleprinter equipment.

196.

Deep Sea Camera.


During the year the design of Cable and Wireless Limited's deep sea camera was finalised, and after successful trials it was used on two surveys, namely Barcelona—Pisa and Canada—Bermuda.

Valuable information about sea-bottom conditions was obtained on high quality pictures down to a depth of 2-1 miles, the maximum so far attempted.

The camera is, however, designed to operate at a depth of over four miles.

197.

D.c. Cable Testing.


Investigations were carried out into the automation of d.c. cable testing, and a timing unit was developed to eliminate the manual operation of the testing keys.

198.

High-Speed Telegraph Relay.

A combination of solid-state and electro-mechanical techniques resulted in the development of a very efficient high-speed telegraph relay for keying and monitoring purposes.

216.

Telex service was established with the following countries: Antigua, Botswana, Dominica, El Salvador, French Antilles, Grenada, Montserrat, Muscat, Nicaragua, St. Kitts, St. Lucia, St. Vincent, Sierra Leone and Trucial States (Dubai).

217.

Telex service is now available to 133 countries.

218.

Leased Circuits.

Active interest continues to be shown in the leasing of circuits.
A total of 91 leased telegraph circuits and 28 leased telephone circuits were being provided at 31st March 1967.

In addition 38 transit telephone circuits and 140 transit telegraph circuits are provided for leasing and public message traffic purposes.

Capacity of Services 219.

Telegraph.

Capacity was available to meet all requirements.

220.

Telephone.

On-demand working prevailed for public services except during peak traffic periods for the Europe—North American working hours.
The additional circuit capacity required for extension of circuits to SEACOM and for increasing Pacific area traffic continued to tax severely available facilities.

The installation of TASI equipment at Montreal and the use of additional satellite circuits will assist in alleviating this situation.

221.

Capacity for public service between Canada and Pacific points was adequate for existing traffic levels.
The requirement for circuit capacity for extension of SEACOM circuits will severely tax the available facilities in the Pacific until the TASI system between Sydney and Vancouver is brought into service.

222.

Telex.

Additional circuits opened on heavy traffic routes according to need, coupled with a major expansion of the Montreal international exchange during March 1967, eliminated delays previously encountered during peak traffic hours.

Rates 223.

Telegraph.


The following changes to telegraph rates were made: Argentina .. Bolivia Italy Jordan Peru Tortola (B.V.I ) Press rate reduced from $0.13 to $0.07.

Press rates reduced from $013 and $0.15 to 80-06.

With effect from 1st October 1966, due to increased Canadian landline requirements, outgoing rates were increased by $0.02 per ordinary word to all Commonwealth and foreign destinations, and $0.01 per ordinary word to destinations where Bermuda pattern rates apply.

At the same time press rates were increased by two-thirds of one cent where rates were formerly one-third of ordinary, and also where rates ended in fractions of thirds.
Where former press rates ended in one-half cent, the rate was rounded up to the next cent.

Bermuda pattern press rates were increased by one-half cent.

Commonwealth press rates remained unchanged.

226.

Installation of the automatic switching equipment for telegraph operations is proceeding and it is expected that this equipment will be put into service during 1967.
231.

Expansion of the telex and telephone switching facilities at Montreal was completed in March 1967.

A further expansion to meet anticipated requirements in 1969 is proceeding.

AUSTRALIAN NATIONAL BODY 232.

Telephone Cable Stations.

For the Commonwealth telephone coaxial submarine cable systems COMPAC and SEACOM at Sydney, N.S.W., Cairns (Queensland), Madang (New Guinea), and Guam (US Territory).
The telegraph cable stations at Cottesloe (Western Australia), and Cocos Island were closed on 31st July 1966.

233.

Radio Stations.

At Doonside (transmitting) and Bringelly (receiving) in New South Wales, Fiskville (transmitting) and Rockbank (receiving) in Victoria, Applecross (transmitting), Gnangara (transmitting) and Bassendean (receiving) in Western Australia.

The Gnangara Station commenced operation on 1st March 1967 for limited (NASA) purposes only.
It will take over all Applecross transmissions during the current year.

234.

Satellite Earth Stations.

At Carnarvon, Western Australia, commenced October 1966, providing for the Apollo project, voice, data and telegraph links between the NASA tracking station in that area and the control centre in the USA.

235.

Under construction, at Moree, New South Wales, and scheduled to become operational in December 1967.

Traffic 236.

Telegraph.


Total telegraph traffic handled by Australia (excluding that from or via other National Bodies) increased from 61.53 million gross words in 1965/66 to 66.05 million gross words in 1966/67 ( + 7.35 per cent).
The variations relative to the individual traffic streams concerned were: From Australian origins and adjacent Commonwealth Islands to Commonwealth destinations .. From Australian origins and adjacent Commonwealth Islands to foreign destinations .. From foreign origins to Australia and other Commonwealth countries .. From foreign origins to foreign destinations 37 Increase in Gross Words 000's Per cent 771 (2.7) 2,489 (12.8) 1,056 208 (8.8) (13.6) (042171) 03 237.
The traffic outward from Australia was substantially influenced by a fall of 1.53 million words in the volume of Press traffic handled (24.4 per cent).

Excluding this press traffic the increase in com- mercial traffic was 11 • 5 per cent.

238.
238.

Little importance can be attached to the marked fluctuation in press traffic because the basic flow of news media is now carried over full-time leased telegraph circuits, with that handled on the public network tending to be directly influenced by the special press coverage given to the exceptional sporting and other news events which have taken place during any particular year.
However, the continued increase in commercial traffic represents a steady growth in the outward flow of traffic from Australia.

239.

Telephone.

Overall traffic handled (excluding that from or via other National Bodies) increased by 560,000 paid minutes ( + 29 -4 per cent) from 1.905 million paid minutes in 1965/66 to 2.465 million paid minutes in 1966/67.

240.
240.

Variations under individual traffic streams were: From Australia To Australia on direct foreign circuits Transit traffic Paid Minutes 000's 488 95 - 23 Per cent (33.9) (22.9) ( -45.6) 241.

The decrease in transit traffic reflects in the main the transfer of USA traffic to South-East Asia from routes via Australia to the direct TPC/SEACOM cable route following the commissioning of the Guam/Hong Kong section of SEACOM in August 1966.

242.
242.

The increases in outward Australian traffic and inward traffic over direct foreign circuits continue the substantial growth in telephone usage arising from the availability of plentiful and reliable broadband coaxial cable circuits.

243.

Phototelegraph.

There was a decrease of 56 from 1,712 to 1,656 in the number of photo- telegrams transmitted during the year.
As with press traffic, phototelegrams normally are associated with sporting and special events and happenings so that fluctuations have no significant long term trend.

244.

Tele.v.

Overall traffic growth (excluding calls from and via other National Bodies) was from 1,232,000 paid minutes in 1965/66 to 1,361,000 paid minutes in 1966/67 (an increase of 129,000 paid minutes or 10.5 per cent).

In detail the variations were: From Australia To Australia over direct foreign circuits ..
Transit traffic Paid Minutes 000's 158 - 23 -6 Per cent (20.7) ( - 5.7) ( -9.0) 245.

The decrease in telex transit traffic is also associated with the opening of the Guam/Hong Kong link of the SEACOM cable, whilst the decrease in traffic received over direct foreign circuits reflects the second year effect of the opening of a considerable number of leased circuit services with Japan during the middle of 1965/66.

246.

Leased Services.


During the year 22 additional circuits were leased to customers and there are now 46 regular users of the Commission's leased circuit services compared with 40 at 31st March 1966.

Several clients rent multiple circuits to the same or different destinations.

Services 247.

Although the Indian Ocean telegraph cable chain was closed on 27th February 1966, the section between Australia and Cocos Islands remained open to provide service to the Islands up to I st August 1966.
Since that date service has been by radio provided by the Department of Civil Aviation as agent for OTC (A).

248.

Telephone.

Telephone services were extended during the year to: Turks Island via Montreal/Jamaica Tortola via Montreal/Barbados Paraguay via Oakland/New York Cambodia via Hong Kong Liberia via London.

249.

Phototelegraph.


The Australia/Canada service was extended to Peru from 15th June 1966, and the Japan/Australia service was transferred from a switched service via Singapore to direct operation from 24th August 1966.

250.

An on demand' service with Seoul via Hong Kong commenced on 10th September 1966.

38 Modernisation and Expansion of the System 252.

SEACOM.

The SEACOM Cable Stations at Guam, Madang and Cairns, constructed and operated by OTC(A), were completed during the year.
The Guam/Hong Kong link came into service on 17th July 1966, and the Guam/Madang/Cairns/Sydney sections (Cairns/Sydney being overland via microwave and coaxial cable) followed on 30th March 1967.

253.

A formal opening ceremony by Her Majesty The Queen, bringing in the entire Common- wealth Telephone Cable system from London to Kuala Lumpur, marked the completion of this major project.

254.

Satellite Earth Stations.


Australia's entry into satellite communication was achieved with the completion of the OTC(A) satellite earth station at Carnarvon, Western Australia, and the successful launching, by the International Telecommunications Satellite Consortium (INTELSAT), of the Pacific INTELSAT II satellite.
A commercial service, providing leased voice/data and telegraph circuits to the USA National Aeronautics and Space Administration (NASA) between Australia and the USA, commenced operation on a full-time basis on 4th February 1967.

On 25th November 1966, the station was used for a live television demonstration relay between Carnarvon and London.

255.

A contract has been let for the construction of a satellite earth station near the town of Moree, New South Wales.
The station is scheduled to be available for operation in December 1967, via the INTELSAT 11 satellite already in orbit over the Pacific Ocean, and will provide connection into the Australian domestic network, not available from the Carnarvon satellite earth station.

256.

HF Radio.
256.

HF Radio.

The Gnangara High Frequency Radio Transmitting Station, Western Australia, was placed in operation on 1st March 1967, with the opening of service on new leased voice/data and telegraph circuits for the National Aeronautics and Space Administration (NASA).

Other services via Western Australia, currently carried by the Applecross Transmitting Station, will be transferred to Gnangara during the coming year.

257.

Telex Developments.


Conversion of the Australian national telex network to automatic operation has enabled the introduction of subscriber-to-subscriber working in the direction incoming to Australia in some cases.

Plans are in hand to provide call charging equipment at the overseas gateway exchange in Sydney in order to permit subscriber-to-subscriber operation in the direction outgoing from Australia.

258.

COMPAC.

Modernisation and Expansion of the System 288.


A new international gateway telephone exchange for New Zealand is to be established at Auckland to replace the present exchange, which was installed in 1961 on a temporary basis to cater for the introduction of the COMPAC cable.

The new exchange will accommodate 60 international circuits and 80 national circuits together with a manual switchboard of 24 positions.
The switchboard will provide for direct operator dialling on outward routes, and also for manual assistance on inward calls as necessary.

Most incoming calls will be switched automatically to the called numbers in New Zealand, and the equipment will also provide for the automatic switching of other international through calls which may require to transit New Zealand in the future.

The new exchange is planned to cut over in May 1968.

289.
289.

It is proposed to provide equipment for automatic ticketing of international telex calls to facilitate the introduction of fully automatic telex operation during 1967.

290.

The number of subscribers to the national telex system totalled 647 as at 31st March 1967, compared with 441 at the same time last year.

291.

With the opening of the SEACOM cable on 30th March 1967, high quality communication links are now available between New Zealand and countries in South East Asia.
It is expected that traffic with these countries will increase substantially.

Traffic 300.

Telegraph.


The originated international traffic handled by the Indian National Body registered an increase of 2.96 per cent in the number of messages and a decrease of 28.66 per cent in the number of words as compared with 1965/66.

The comparison of wordage with 1965/66 is misleading because of the very abnormal wordage registered in 1965/66 due to international events involving India.
About 50.48 million originated words (about 1 .6 million originated messages) were handled during the year.

301.

Telephone.

The originated telephone traffic (including programme transmissions) registered an increase of 18.91 per cent in number of calls and 18.14 per cent in total number of paid minutes as compared with the previous year.

About 245,000 paid minutes were handled during the year.
Some significant improvement in the quality of service offered has been noticeable on the main India—Britain services following the technical improvements in aerials and the various operational steps taken jointly with the British National Body.

A quarter-speed radioteleprinter circuit has been in use between London and Poona international telephone exchanges for handling ancillary information on the telephone traffic.
The utility of this arrangement has been confirmed, and plans are under way to extend this arrangement between London and other Indian international exchanges at Calcutta and New Delhi by organising a tape relay at Poona to link with Calcutta and New Delhi.

302.

Telex.

Originated international telex traffic registered an increase of 26.74 per cent in number of calls and 19 per cent in number of paid minutes as compared with the previous year.
About 322,000 paid minutes of originated traffic were handled during the year.

Two of the telex circuits on the London—Bombay route were converted to semi-automatic from 8th July 1966, marking the beginning of direct access to the automatic domestic telex network.

Most of the international telex traffic is cleared over 5 circuits between Bombay and London, 4 circuits between New Delhi and London and 3 circuits between Calcutta and London.
The total number of international telex circuits operated from India is 17.

303.

Phototelegraph.

The originated phototelegraph traffic registered a decrease of 35.10 per cent in messages and 32.99 per cent in total area over the previous year.

During the year 429 messages with a total area of 172,050 sq.

THE BOARD'S ACCOUNTS 514.

The Statement of Accounts for the year ended 31st March 1967, duly certified by the Board's Auditors, Messrs. Thomson McLintock & Co., is attached to this Report.

515.

The total expenditure for 1966 /67 was £97,389, compared with £105,650 for 1965/66, and came within 1 per cent of the Budget.

516.
516.

The decrease in expenditure in 1966/67 was mainly due to the inclusion in 1965/66 of certain non-recurring items.

There was also less spent on overseas travel.

517.

Contributions from National Bodies received in 1966/67 included £1,100 from Nigeria and £850 from Ghana in respect of 1965/66 and an advance against 1967/68 expenses from Zambia.

Amounts totalling £1,034 due from two National Bodies were outstanding at 31st March 1967.
It was found unnecessary to call for the final instalment (€7,950) of Britain's contribution, because this would have unduly inflated the cash balance.

VII.

ACKNOWLEDGMENTS 518.

The Board is again greatly indebted to the Administrations and National Bodies of the Partner Governments for their co-operation in all aspects of the Board's work.
