The VLNC35 circuit packs provide four 100BASE-T, IEEE 802.3 compliant electrical interfaces that are capable of spanning distances of 100 meters.
The VLNC35 provides optical 100BASE-LX IEEE 802.3 compliant (100 Mb/s) fast Ethernet interfaces that are capable of spanning distances of 10,000 meters. The PTM port performs protocol transparent filtering and bridging of incoming media access control (MAC) frames. MAC frames with a destination address on the local bus are filtered by the circuit packs to prevent unnecessary transmission of frames over the wide area network (WAN). The interface auto-negotiates mode (full/half duplex) and speed (10/100 Mb/s) when interfacing with other 802.3 compliant devices over twisted pair media.
The VLNC35 circuit pack must be housed in slot 1 of Function Unit C and is not equipment protected. However, facility protection can be provided through the WAN via SONET (UPSR/SNCP, or 1+1) and/or through the IEEE 802.1W spanning tree algorithm.
For a detailed list of PM parameters and thresholds, refer to Ethernet performance monitoring parameters in Chapter 5, Operations, administration, maintenance, and provisioning.
