The GbE-2ch module accepts one or two 10/100/1000 BaseT signals, provides rate policing and VLAN tagging and transfers them to the MD8000 SW-CNT modules. In the receive direction, the 2GbE module accepts Ethernet packets transferred from the SW-CNT and provides one or two unique 10/100/1000 BaseT output signals.

Two completely independent bi-directional GbE channels ensure that data on the individual ports is kept separate, permitting operation at full wire speed rates with total isolation. Both ports support Auto-Negotiation.

The GbE-2ch board has two modes of operation; transparent or port tagging mode. Both modes handle packets up to Jumbo frames (up to 9022 bytes in length including headers and FCS). Port tagging is utilized for point-to-point connections with path failover protection. Transparent mode is used for multiple point WAN connections. In addition the GbE-2ch board provides input filtering and rate policing to guarantee that data cannot impact video traffic. Either optical or electrical rear boards can be used for the GbE-2ch line module.
