The LNW170 circuit packs provide four 1000BASE-X (SX, LX, and/or ZX- very long reach 80km), IEEE 802.3-compliant (1000Mbps) GbE interfaces and four 100BASE-ZX/LX/FX IEEE 802.3-compliant (100 Mbps) fast Ethernet interfaces. The LNW170 circuit packs provide Ethernet private line or switched services, with QoS. Protection is provided via SONET UPSR/BLSR or through the IEEE 802.1w (or 802.1d) spanning tree algorithm.
The LNW170 can also use electrical PTMs that are provisionable to support either 100BASE-T or 1000BASE-T traffic. The electrical PTMs can occupy ports 1−8.
The LNW170 is an unprotected pack by default. Alcatel-Lucent 1665 DMX supports link aggregation on LNW170 LAN ports, which can be used to provide facility protection. The LNW170 can also support aggregation across LNW170 circuit packs. For more information on Link Aggregation, see Link aggregation (LNW170 LAN ports).
When Alcatel-Lucent 1665 DMX is equipped with non-VLF Main packs, unprotected LNW170 packs can only be placed in Slot 1 of any Function Unit group or Growth slot on the shelf (A1–G1) and Alcatel-Lucent 1665 DMX supports a total add/drop capacity of 20 1000BASE-X ports and 20 1000BASE-ZX ports if all available slots are equipped with LNW170 circuit packs. If the LNW170 circuit packs occupy only slot 1 of a Function Unit group, slot 2 must be populated with an apparatus blank. However, the LNW170 can be populated on both slots with non-VLF Mains if it is in equipment-protected mode.
When Alcatel-Lucent 1665 DMX is equipped with VLF Main (LNW59, LNW82, or LNW504) packs, Ethernet packs can occupy both Slot 1 and 2 of a Function or Growth Unit (where applicable). With VLF Mains and all tributary slots populated with LNW170 packs, up to 40 1000BASE-X and 40 100BASE-LX ports are addressable.
The LNW170 can utilize 1000BASE-X optics. The LNW170 can also utilize 100BASE-X PTM optics for optical fast Ethernet. These PTM optics can be ordered and plugged into the LNW170 as their capacity becomes needed.
For the detailed specifications of these optics, see:
The LNW170 use electrical PTMs that are provisionable to support either 100BASE-T or 1000BASE-T traffic. The electrical PTMs can occupy ports 1−8.
The dual function electrical PTMs are provisionable for 100 or 1000 Mbps traffic. They 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).
For more information on the PTM optics available for the LNW170, see 100/1000BASE-T electrical Ethernet specification and 100/1000BASE-X/T (optical/electrical) Ethernet (LNW170).
Performance monitoring capabilities are available on the LNW170 circuit packs. A detailed list of monitored parameters can be found in Performance monitoring.
