For example if a user needs to provision an STS-3c or STS-1-3v on the CE-100T-8 card shown in
Figure 17-4, an STS-3c or STS-1-3v worth of bandwidth is not available from either of the two pools.
The user needs to delete circuits from the same pool to free up bandwidth. If the bandwidth is available
but scattered among the pools, the circuit cannot be provisioned.
Looking at the POS Port Map table, the user can determine which circuits belong to which pools. The
Pool and Port columns in Figure 17-4 show that the circuit on port 5 is drawn from Pool 2, and no other
circuits are drawn from Pool 2. Deleting this one circuit will free up an STS-3c or STS-1-3v worth of
bandwidth from a single pool.
The POS Port table has a row for each port with three columns (Figure 17-4). They show the port
number, the circuit size and type, and the pool it is drawn from. The Pool Utilization table has two
columns and shows the pool number, the type of circuits on that pool, how much of the pool’s capacity
is being used, and whether additional capacity is available.
CE-100T-8 VCAT Characteristics
The ML-100T-8 card and the CE-100T-8 card (both the version for the ONS 15310-CL and
ONS 15310-MA and the version for the ONS 15454 SONET/SDH) have hardware-based support for the
ITU-T G.7042 standard link capacity adjustment scheme (LCAS). This allows the user to dynamically
resize a high order or low order VCAT circuit through CTC or TL1 without affecting other members of
the VCG (errorless). ML-100T-8 LCAS support is high order only and is limited to a two member VCG.
To enable end-to-end connectivity in a VCAT circuit that traverses through a third-party network, you
must create a server trail between the ports. For more details, refer to the "Create Circuits and VT
Tunnels" chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.
