4 E1 to Ethernet GFP Converter

Overview

The 4 E1 to ethernet converter  is the IP ethernet over TDM converter, which supports the conversion from MAC frames to 1 – 4 E1 lines. The maximum bit rate is 7.8Mbps (4E1 lines). The 4E1 converter not only provides alarms and status of the E1 line but also Ethernet interface together with advanced management functions, such as, throughput statistic of the Ethernet, but also supports the Unification Network Management via SNMP and GUI .

Features:

 n  E1 interface

?        Supports automatic removal and recovery of E1 channels that used for carrying payload. The E1 channels that have urgent alarm, such as LOS and LOF, or the Bit Error Rate (BER) exceeds 1E-6, are removed automatically, and during this period, some Ethernet packets may be lost; It will be resumed when the fault dismisses .

?        Supports the embedded E1 BER Tester function, to detect any E1 channel of  4 channels. When the embedded E1 BER Tester is used via CLI command, the particular E1 channel on testing mode can not convey E1 service, while the other E1 channels are not affected by the BER test.  

?        The differential delay between any two of the 4 E1 can be up to 220ms; when the factual differential delay exceeds 220ms, alarm is generated and Ethernet is cut off.

?        Jitter tolerance and jitter transfer characteristic compliant to ITU-T G.823.
