BD-FE1-4ETH-MM is Fast Ethernet over 1 or 2-port E1 protocol convertor. Ethernet traffic over E1 lines is transferred to the packet-switched network via the unit’s Fast Ethernet ports. The encapsulation method support HDLC/PPP-BCP(RFC3518)/GFP-F.

Typical Applications

The device can be used in a point-to-point application or in a hub-and-spoke topology, operating opposite Grancom’s CS1200 series, MRS46xx series and third-party gateways.

Typical applications include:

l  Ethernet private Line/LAN services

l  IP DSLAM, cellular IP, and WiMAX base station backhauling 

l  Interoffice or enterprise LAN connection. 


   ●   Built-in intelligent switch fabric and provide 4-port fast Ethernet

   ●   Support 2047 bytes frames

   ●   Up to 2K MAC address entries                                                                      

   ●   Support IEEE802.1Q VLAN and QinQ double tagging

   ●   Support HDLC/PPP-BCP(RFC3518)/GFP-F encapsulation

   ●   Support E1 frame or un-frame application

   ●   Provide statistics for each E1 channel

   ●   Configure via CLI/Web/SNMP(v1/v2c)

   ●   Support software and firmware upgrade
