PCL Controller Overview
Xedge Switch Version 7.20 and later supports the Xedge Packet Cell Link (PCL).
PCL is a dual-width card that support all features found in the ISG2 along with
the added features listed below.
Features & Benefits
•
Cost-effective DS1 IMA to DS3, or E1 IMA to E3 cell-relay transport
•
ATM standard compliant ATMF UNI 3.1 solution
•
Conformance with IMA 1.0 and IMA 1.1 standards
•
NNI support for both DS1/E1 IMA or DS3/E3 ATM
•
Fast Ethernet for management and/or Ethernet/IP data (up to 4 connections)
•
ATM loopback and diagnostic of physical layer performance
•
Optional choice of PLCP and HEC formats for DS3/E3
•
Xedge platform supports migration to Ethernet/IP MPLS applications
Routing
PCL determines routes based on IP destination addresses. PCL builds layer-3
tunnels across the Xedge cloud to other PCL devices and selected Layer-3 devices
(e.g., centralized router resources or external routers connected to the network via
MPLS or ATM interfaces). Each PCL supports from 20 to 40 IP tunnels which
may be established using OSPF, RIP2, or deterministic MPLS/ATM routes, or by
selecting a specific PCL tunnel as a local site’s default gateway. PCL can be
configured with auto re-routing, along with variations on limited and restricted
re-routing.
