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)
