INT-9321 ITU / CEPT E3 / E1 Multiplexer / Demultiplexer


 The INT-9321 is a multiplexer and demultiplexer for ITU / CEPT telecommunications standard E1 rate (2.048 Mbps) to / from E3 rate (34.368 Mbps) PCM signals. The multiplexer accepts up to 16 E1 inputs and a produces single E3 output. The demultiplexer accepts a single E3 input signal and provides 16 E1 outputs. For line interface testing local side loop-back of the E1s and remote side loop-back of the E3s is provided. The INT-9321 is enclosed in a full width 1U (1.75 high) rack mount chassis, and operates from either 120 / 240 VAC 50 / 60 Hz AC power, or optionally DC power. The unit may be controlled from its front panel or remotely via its serial RS-232C interface.
