Product Description

1. Summary
This compact desktop ZMUX-08E is the fundamental device for the digital communication system, which is also named PCM basic group device. The device is used to multiplex the signals such as voice, data and image into a
standard 2M link via various interface cards, realizing point-to-point transmission.
2. Functional Features
a) It provides 8 channels of optional subscribers interfaces of various types to facilitate the access of various
services;
b) It provides 2M channel for transmission directly;
c) The voice interface supports caller ID display;
d) CCB payphone application with polarity reversal;
e) The bit rate of the port marking 10Base_T is 64kbps.
f) Perfect indications of status are available to facilitate maintenance and management;
g) With very small size, attractive appearance, and easy for installation and operation
