Title: Data communication systems
IPC: H04M3/24
Filed: 1976-06-17
Abstract: 1524984 Data exchange systems STANDARD TELEPHONES & CABLES Ltd 17 June 1976 [24 June 1975] 26712/75 Headings H4P and H4K A remote control and supervisory system includes a processor at a control station and a number of outstations, with the processor being connected to the outstations by data links to each of which one or more outstations may be connected. Each data link conveys one or more data channels each providing fully duplex facilities with at least one data channel conveying messages relating to different outstations in TDM or FDM manner and being divided into at least two sub-channels with each sub-channel comprising a plurality of TDM or FDM multiplex channels. The individual multiplex channels can each transmit a multibit data group and the arrangement is characterised in that for messages relating to some operations a multiplex channel in more than one sub-channel per data channel is used whereas other operations utilize only one multiplex channel per data channel. Such an arrangement is used because some operations require higher signalling rates than others. The system is additionally of the type wherein outstations are polled from the central station using a message including an outstations address which is sent broadcast to all outstations served by a particular data channel, with a return message, if any, from the outstation being sent a predetermined time interval after the receipt of the polling message. The arrangement is applied to a testing and statistical metering system for a telephone exchange system wherein a central station is coupled by data links to outstations constituted by equipment at a number of different telephone exchanges. In the embodiment of Fig. 5 (not shown) each delay link is split into 3 two way channels A-C, each two way channel comprising two separate one way channels, and each two-way channel is allocated to messages associated with particular groups of functions, e.g. channel A is used for quality of service measurement, channel B for subscribers line apparatus testing, alarms, and control commands and channel C for traffic measurement. Each one-way 25 channel of channels A and B is divided into 4 sub-channels of 0À5s and each sub-channel has four bit groups of 0À125s, the 16 bit groups of a channel being transmitted as a frequency division multiplex. Each bit group comprises either 38 or 37 bit positions such that one 300 baud channel is contituted by the occurrence of one bit group per data channel. A rate of four bit groups per data channel, i.e. one per sub-channel may be used when setting up a test call using multifrequency signalling, and a rate of two bit groups per data channel for alarm messages during a call set up phase if a test call. In a further embodiment (Figs. 1-4, not shown) each multiplex channel constitutes a 150 baud data channel and time division multiplex is used.
