Abstract
An assembly comprising a program controlled switch and (IP) Module providing signal compression and decompression and packet assembly and disassembly (PAD). The arrangement provides compression and packetizing of digitized voice and data signals between the conventional switch line interface units and the switch fabric, and/or between the line interface units and the time slot interchange in the interface module. Voice channel signals which have been digitized to 64 Kb/s D0 signals are packetized and packet switched to improve the efficiency of the program controlled switch assembly and also provide convenient Internet access via direct connection to ISP routers.
