摘要:
A time-space-time switching network is shown in which there is a multiple crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in either or both the originating and terminating time switching stages but remain segregated throughout the space switching stage.

A space stage for a T-S-T digital switching system is shown arranged into four identical space stage units (SSU). Each SSU is arranged into modular functional elements. The elements are combined in each SSU to allow the space stage to grow modularly, interconnecting from thirty-two to sixty-four originating time and terminating time stages.

摘要:
An arrangement for interfacing the originating time stage (OTS) and terminating time stage (TTS) of a time and control unit (TCU) to the space stage of T-S-T digital switching system. The space stage includes an intra-path through the space stage as well as an interpath. The interface transmits PCM samples simultaneously from the OTS to both the intra and interpaths of the space stage. PCM samples from the space stage are received by an intra buffer and an inter buffer from the intra path and inter path respectively. A TCU control memory gates and connects either the intra buffer or inter buffer to the TTS.
摘要:
A space stage for a T-S-T digital switching system is shown arranged to interconnect the originating time stages (OTS) and terminating time stages (TTS) of a first time group and the OTS's and TTS's of a second time group. The space stage includes four identical space stage units (SSU). The first SSU interconnects the OTS's and TTS's of the first time group and the second SSU the OTS's and TTS's of the second time group. The third SSU interconnects the OTS's of the first time group to the TTS's of the second time group and the fourth SSU interconnects the OTS's of the second time group to the TTS's of the first time group.
