摘要： A telecommunications system includes a telephone exchange and a customer services terminal whose input is connected to the telephone exchange, and whose plural outputs are individually connected to one of a plurality of telephone lines. A plurality of interface circuits within the customer services terminal are individually connected intermediate the input and one of the plural outputs. Self-test means provides for the testing of selected interface circuits. Loop-test means provides for the testing of selected telephone lines. A self-test relay is responsive to the self-test means and operates to disconnect the selected outputs from corresponding telephone lines as self-test conditions are applied to selected interface circuits as these interface circuits are disconnected from the selected telephone lines. The loop test means applies loop-test conditions to selected interface circuits, while the selected interface circuits and the corresponding outputs remain connected to the corresponding telephone lines. In either case, other interface circuits, outputs, and telephone lines that are not undergoing test remain operative to supply telecommunications services between the telephone exchange and these other telephone lines.

摘要： A technique for performing a time slot interchange in a processor. The TSI process is surrounded by a multiplexing/demultiplexing circuit for converting a plurality of PCM highways into a single input serial data stream. The mux/demux circuit includes elastic stores to align frames and shift resisters to mux/demux with a minimum of delay. The TSI processor includes an input and an output buffered series port, a pair of input buffers, one to receive even-numbered frames from the PCM highways and one to receive odd-numbered frames, and an output buffer. Data is read from the appropriate input buffer in a non-sequential fashion as commanded by the processor in accordance with information stored in connection arrays (address buffers). The data is then written to the output buffer sequentially. The timing of the reading and writing steps is optimized relative to free running buffered serial port pointers for each BSP to reduce the frame delay.

摘要： A multiplexer device for multiplexing and demultiplexing signals between a low-speed network including 28 DSX-1 signals and a relatively higher speed network including a DS-3 signal. The multiplexer device includes 7 quad DSX-1 cards and 1 spare card. The spare card is connected to the other 7 DSX-1 cards in a fashion that allows the spare card to automatically be switched in for one of the DSX-1 cards or to allow interface electronics on the spare card to replace selected ones of the interface electronics on various different DSX-1 cards simultaneously. A pair of controller cards, a primary card and a secondary card, perform the M1-3 multiplexing and demultiplexing and the DS-3 framing and transceiving. The controller cards can be selected or deselected by distributed logic in a sufficiently short time period so that alarms are not set off and so that the transition is hitless. This is accomplished by electronically enabling and disabling the transceiver. The multiplexer device is connectable to 2 different T-3 links to provide network redundancy. An array of relays provides for the connection of either controller card to either of the T-3 links. The controller cards are externally connectable to a computer network such as an Ethernet for external control thereof through SNMP or Telnet sessions. The multiplexer device is housed within a significantly reduced volume which occupies only a single rack unit on a standard 19" or 23" wide vertical rack used for telecommunications equipment. The significantly reduced volume is partially due to a dual backplane architecture in which an external backplane serves as the external connector plane while a separate internal backplane serves as the connection to the various DSX-1 cards and controller cards.
