ABSTRACT:
In a private line multiplexing device a multi-priority buffering system is used to control the transmission of supervisory signaling information and normal messages onto an available communication channel. The system includes a multi-priority message buffer, a queue map for logging entries in the buffer, an output time map and a controller. The controller tags incoming data (be it a normal message and/or signaling information) and stores the data into the priority buffer. The tag may include a priority classification, identification, entry-time, etc. Signaling information is assigned a priority I designation while newly generated voice packets are assigned priority IV. As communication channels become available data is shifted, in accordance with a priority algorithm, from the buffer to the channel. Furthermore, the algorithm ensures that stacked messages from a common source are transmitted on a delayed basis.
