Bandwidth management
The 2xGigE/FC-P2P circuit pack supports both contiguous and virtual
concatenation bandwidth provisioning.
Contiguous concatenation
When the VCAT attribute in the WAN port is set to DISABLE, only one
connection (STS-1, STS-3c, STS-12c or STS-24c) can be cross connected to a
2xGigE/FC-P2P WAN port.
— SONET contiguous (STS-1, STS-3c, STS-12c and STS24c)
