At a transmit site of an inverse multiplexing system, an input demultiplexer demultiplexes high bandwidth serial communication signals (e.g., fractional Trate signals) into communication signal packets for transmission over reduced bandwidth serial communication (e.g. T) channels. A multiplexer for each channel combines successive packets of demultiplexed signals with bits of multibit packet reassembly control words that identify the channel and the order in which communication signal packets have been demultiplexed, to produce successive frames for transmission over the channel. At a receiver site the control words are extracted from the frames of data and analyzed to control reassembly of the serial data packets into their original order.

A called telephone number substitution mechanism is incorporated into the call-routing software employed by the microcontroller of a customer premises-installed communication device, through which digitized voice and data services are supplied to a customer site. The number substitution mechanism automatically selectively modifies digits of an original (dialed) telephone number, as necessary, to conform with the connectivity requirements of the communication link serving the destination device, thereby enabling the call to reach the destination device.
