Dynamically reconfigurable time-space-time digital switch and network

摘要

A dynamically reconfigurable time-space-time (DRTST) switching system for use in conjunction with a high speed transmission media which conveys a plurality of time division multiplex (TDM) channels within a repeated frame of data is provided. The system includes a bypass for selectively opening the transmission media. A control store is connected to the bypass for receiving selected channels, one of said selected channels comprising a control channel. A TST switch having a plurality of inlet ports and a plurality of outlet ports is provided wherein the inlet ports are connected to receive selected channels from the bypass, and the outlet ports are connected to the bypass for transferring data from the TST switch to the transmission media. The control store responds to commands received through the control channel for dynamically allocating active ones of the selected channels to respective inlet ports of the TST switch, for dynamically allocating receipt channels of the selected channels to the outlet ports and for routing the data from the active ones of the selected channels through the TST switch to a selected one of the outlet ports wherein the data for the active selected channel is returned to the transmission media to thereby accommodate various types of data.
