Reurairtel 4/12/65 in captioned matter furnishing details for the

proposed MISUR installation at 902 South 8th Street, Philadelphia. The

following technical details are set forth for the information of the sound-

trained Agents of your office.

A review of the technical data indicates the ZAM unit will perform

satisfactorily in captioned installation. Accordingly, the Western Electric

500 L/M telephone instrument, previously furnished by your office, is being

altered to include the ZAM unit in the network.

When the alteration has

been completed and tests made under simulated line conditions similar to

those described in reairtel, the telephone instrument along with other

equipment for remote controlling the

SPMT urit will be forwarded to

Philadelphia.

Tests suggested by your telephone company source may be

conducted under controlled conditions in room 66 of the Federal Building

by the source temporarily assigning a number from the same exchange as

the target instrument. The requested tests should be completed within a

short time and should not delay installation at the target area more than one day.

Authority to install will be handled separately.

NOTE: Target area is a known meeting place for members of captioned

organization. An on-the-spot survey conducted by the Laboratory and conferences

with telephone company sources indicate that the SPMT approach is the only

media for effecting MISUR coverage. Special remote control SPMT equipment

will be used for this installation. 'All switching equipment will be concealed

in Bureau-assigned space in the Federal Building. Telephone company

records will not indicate routing of target service through Bureau-controlled

space.

Re visit of Supervisor CHARLES K. CORBETT, of the

Laboratory, to Phila. 4/5/65.

Phone company contact has furnished a tabulation of

resistances requested as follows:

Customer to Market 7 exchange, 9th and Race Streets

204 ohms

MA 7 exchange to Federal Building, 9th and Market Streets

72 ohms

basement

4th floor Nain FEs en Federal Bullding, to Room 56 In

Since the last two figures would require pairs both

to and from these locations,

these figures

should be doubled.

Accordingly, the total resistance would be 204 plus 144, plus

50, equals 398 ohms.

Sufficient spare pairs are available between the

Federal Building and the MA 7 exchange so that extra pairs

could be used to halve that resistance.

Contact recalled telling SA CORBETT that customer was

in transmission zone 1. A check revealed customer is actually

in transmission zone 2.

He noted, however, that this would

make it more logical that the 300

with a 500 series.
