Abstract:

Standard multipoint junction units (MJUs) are used in parallel-connected MJU sets for a private multipoint data communications network. The MJU sets provide communications between remote terminals and a central site at rates faster than those provided by a stand-alone MJU. On the remote terminal side of the MJU set, data from a remote terminal on two or more adjacent channels are carried on a multichannel transmission line, such as a T1 line, to a transmission line port unit. Adjacent output channels from the port unit are connected to branch ports of each MJU of the MJU set, such that the branch port of each MJU that is associated with that terminal receives one channel. On the central site side of the MJU set, adjacent channels are connected from a transmission line port unit to the master input of each MJU. Connections between the MJU ports and the port units are through a time slot interchange matrix, which ensures that the data is maintained in its proper sequence.
