INT-9321 ITU / CEPT E3 / E1 Multiplexer / Demultiplexer
Overview
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 E1’s and
remote side loop-back of the E3’s 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.
