A digital concentrator for the SLC TM -96 system
TLDR
The SLCTM-96 subscriber loop carrier system is a digital subscriber carrier system serving up to 96 single-party customers that employs a custom NMOS lsi chip providing a full-access, time-slot interchange function.Abstract:
The SLCTM-96 subscriber loop carrier system is a digital subscriber carrier system serving up to 96 single-party customers. The system can be configured with an optional plug-in which digitally concentrates two standard, 1.544 megabit, serial pulse-code modulation (PCM) bit streams into a single stream, thereby concentrating 48 customers onto a single T1 digital line. The concentrator employs a custom NMOS lsi chip providing a full-access, time-slot interchange function. It has microcomputer controllers at the two ends of the system to control time-slot assignments. The development of the concentrator involved challenges in chip design, software design, and performance testing.read more
