Functions

8E1 to optical Ethernet converter is the IP over TDM converter, which supports the conversion from MAC frames to 1 -8 E1 lines. The maximum bit rate is 15.744Mbps (8E1 lines) . With different LAN card, E1 card and power card, it can meet various requirements. It not only provides alarms and status of the E1 line and 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 .
Compliant to international standards, the device can communicate with products from other manufacturers adopting the same standards.
