Abstract
A modular, reconfigurable, intelligent signal multiplexer for telecommunications purposes includes multiple feature cards. Each feature card contains an embedded microprocessor with associated RAM memory and flash ROM. The signal multiplexer processes digital inputs from a wide range of user equipment for transmission over digital facilities, including T1 and T3 lines. The system employs an Advanced Intelligent Multiplexer Network software package to perform network configuration and the establishment of maps. The maps including alternate maps, which in an embodiment include time-of-day-specific alternate routes. The functions of the signal multiplexers of a network are controlled by a mapping scheme. A map change alters the circuit-to-time slot assignments.
