11.18.5 Open-Ended VCAT
• FC_MR-4 (line mode) card—All VCAT circuits using FC_MR-4 (line mode) cards have a fixed
number of members; you cannot add or delete members.
• ML-Series cards—All VCAT circuits using ML-Series cards have a fixed number of members; you
cannot add or delete members.
Table 11-18 summarizes the VCAT capabilities for each card.
11.18.5 Open-Ended VCAT
For applications where the complete end-to-end VCAT circuit is not in a CTC managed network, CTC
will only see either the source or the destination of the Virtual Concatenated Group (VCG) and some of
the intermediate nodes. Figure 11-16 shows an end-to-end VC AT circuit. The termination points of the
end-to-end VCAT circuit, with VCAT functionality, are referred to as the VCAT-Source and
VCAT-Destination. The termination points of the CTC managed circuit, which is the Open-Ended VCAT
circuit, is referred to as simply the Source and Destination.

1. When adding or deleting a member from an LCAS VCAT circuit, Cisco recommends that you first put the member
in the OOS-MA,OOG service state to avoid service disruptions.

2. For CE-Series cards, you can add or delete members after creating a VCAT circuit with no protection. During the
time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry
traffic.
