TLDR
In this article, a clock synchronized time division switches are connected respectively to the input signal lines, bus highways, and the output signal lines in a multihop system, and each one is controlled by its own storage of selected addresses in time slot order.
Abstract
Ports including at least input and output signal lines are collected into port groups. For each port group three separate clock synchronized time division switches are connected respectively to the input signal lines, bus highways and the output signal lines. All time division switches of the system are synchronized by a system clock and each one is controlled by its own storage of selected addresses in time slot order. A plurality of bus highways is provided and the input time division switch connects signals to a specific bus highway of the system. A second time division switch selects the bus highway for connection to the output section of the port group. A third time division switch selects the output port to which the selected bus highway is connected. In one embodiment the bus highways directly connect the port groups. In another, a central inter-connect matrix is provided to make the connection between the first and second time division switches.

Process for determining active channel configurations in a multiplex communications system and a system for implementing said process

TL;DR: In this article, a variable configuration multiplex transmission method is adapted to proceed to such a channel determination by multiplexing a predetermined particular character from the active channels, directly transmitting over transmission channel (32) the multiplexed predetermined character burst, receiving (34), and using the received character burst in order to read a pre-registered table which directly gives out that channel configuration which has active channels.
