The LNW63/64/87/170 circuit packs support dual function electrical Pluggable Transmission Modules (PTMs), also known as small form-factor plug-ins (SFPs), that are provisionable for either 100 or 1000 Mbps traffic. On the LNW170 and LNW87, the PTMs can function at both 100 and 1000BASE-T rates. On the LNW63 and LNW64 only the 1000BASE-T rate is supported.
The electrical Ethernet PTMs conform to the IEEE802.3 standards for 100BASE-T and 1000BASE-T in the respective settings (IEEE802.3z and IEE802.3ab). Connectivity is provided for an RJ-45 Cat 5 cable and the PTM has a maximum span length of 100 meters.
The 100/100BASE-T Ethernet interfaces comply with the following transmission standards:
standard IEEE 802.1D for transparent bridging and spanning tree protection.
standard IEEE 802.3, Section 25 for 10/100 Mb autonegotiation (including flow control, full-duplex transmission, and half-duplex transmission).
Performance monitoring capabilities are available on the 10/100T circuit packs. For a detailed list of monitored parameters, see Performance monitoring.
