The 8x 1GbE module accepts one to eight 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 8 x 1GbE module accepts Ethernet packets transferred from the SW-CNT and provides one to eight unique 10/100/1000 BaseT output signals.

Eight 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. Auto-Negotiation is supported on all 8 ports. In addition, customer loopback and continuity checking functionality is also provided to facilitate circuit setup and operational troubleshooting.

The 8x 1GbE module has four encapsulation/decapsulation modes of operation: Transparent, Double Tag, Tunneling and Tag Exchange (Over Write). All modes handle packets up to Jumbo Frames (i.e. maximum of 9022 bytes in length including headers and FCS). Input filtering and rate policing is provided on each individual Ethernet circuit to guarantee that data bursts cannot disrupt overall traffic flow. Either optical or electrical SFPs can be used on the rear panel.

A 4x 1GbE line module (with rear panel SFP cage) is also available that accepts one to four 10/100/1000 Ethernet BaseT signals.
