STS/VT Allocation

Use the STS/VT Allocation subtab to display how provisioned circuits populate the pools. Use this information to free the bandwidth required for provisioning a circuit, if there is not enough existing capacity on any one pool for provisioning the desired circuit. All virtual concatenation (VCAT) circuit members must be from the same pool. One of the four memory pools is reserved for the low-order VCAT circuits, if sufficient bandwidth exists to support the high-order circuits on the remaining three pools. To help prevent stranding bandwidth, provision your high-order VCAT circuits first to distribute them evenly. For a list of ONS nodes and cards that support this subtab, see Maintenance.


POS Port Map area	Displays the port map information.
Port	Identifies the port on which a circuit is provisioned (only one circuit per port is allowed).
Allocation	Displays the number of STSs/VTs used by the circuit provisioned on the port. If the circuits provisioned are LO VCAT, there is a maximum of 84 VT1.5s with SONET.
Pool	Identifies the pool in which the STS/VTs are categorized. The ONS 15310-CL and ONS 15310-MA CE-100T-8 and ML-100T-8 cards have two pools; the ONS 15454 CE-100T-8 card has four pools.
Refresh	Updates the table with current data.
Pool Utilization area	Displays the pool utilization information.
Pool	Identifies the pool number. The ONS 15310-CL CE-100T-8 and ML-100T-8 cards have two pools; the ONS 15454 CE-100T-8 card has four pools.
Type	Displays the type of circuit the pool currently supports (STS or VT).
Circuit Usage	Displays the maximum number of circuits per pool and the number of currently provisioned circuits per pool; for example 1 of 4. Display options are x of 4 on pools 1 and 2 and x of 3 on pool s 3 and 4. I
Pool Usage	Displays the maximum number of STSs or VTs per pool and the number of currently provisioned STSs or VTs in the pool; for example, 68 of 84 VTs.
Pool Available	Indicates availability of the pool for the new circuit (Yes or No).
Help	Displays context-sensitive help.
