…Challenges Over the past decade, service providers introduced the first generation of Ethernet Wide Area Network (WAN) services. Generally, these were based on Ethernet ports integrated in SONET/SDH systems for point-to-point Transparent LAN Service, or best-effort multipoint Ethernet service based…

The ESLM maps Ethernet packets to SONET/SDH frames using industrystandard mechanisms: Generic Framing Procedure (GFP), Virtual Concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS). This module supports 10 x GbE or 1 x 10GbE ports and up to 64 SONET/SDH Virtual Concatenation Groups (VCGs),…

…-impacting central switch matrix card switch-outs. The CN 3600 offers a full array of Ethernet cards from 10/100bT and 100bFX to Gigabit—all supporting standard GFP for transparent transport over any SONET/SDH network, as well as virtual concatenation for aligning service bandwidth to transport…
