Facility Attributes - Nortel NTRN10AN Planning Manual

Virtual concatenation
When the VCAT attribute in the WAN port is set to ENABLE, up to 7 STS3c
or 21 STS1 connections can be cross connected to a 2xGigE/FC-P2P WAN
port.

When the VCAT attribute of the WAN port 1 and port 2 is set to DISABLE,
if a STS1 granularity connection is made against one of these ports, the
only valid connection that can be made against the other WAN port is STS1
connections.
When the VCAT attribute of the WAN port 1 and port 2 is set to DISABLE,
if an STS-nc (STS3c, STS12c or STS24c) connection is made against one
of these ports, the only valid connection that can be made against the other
WAN port is STS-nc connections.
When the VCAT attribute of WAN port 1 and port 2 is set to ENABLE,
both ports must have the same RATE attribute.
