E1 Fiber Modem

provide a light interface, two devices to V.35-butt or mode provide an E1 interface, framing and non-framing optional

Description:

The FHC-4030G is designed to provide fiber connection for E1 equipment. It includes a E1 Line Interface Unit that provides E1 line driver/receiver,data/clock recovery, jitter attenuation, AMI/B8ZS/HDB3 encoding, AIS (Alarm Indication Signal) detection, BPV (Bi-Polar Violation) detection, and loop back mode. It offers two modes of Loopback for testing the connection integrity. In the Local Loopback mode, the modem loops back the received E1signal. In the Remote Loopback mode, the modem sends loopback codes to cause the far-end modem to loop back the received optical data.

Features

provide a light interface, two devices tou uV.35-butt or mode

provide an E1 interface, framing and non-framing optional

support of the main timing, tracking E1 interface, track-mouth, two-wayu asynchronous timing of four regular pattern;

E1 interface for the CRC / non-CRC-frame framing model can automatically adapt

E1 interface input jitter-tolerance and jitter transmission characteristics superior to industry standards, adapt to the complex network

with multiple functions and built-in the circular line error testing capabilities to facilitate the opening of detection;

with remote power detection equipment, theu distinction can be broken or remotely power defibrillators

rich panel that makes it easy for usersu determine fault
