VC4/VC LO Allocation

(Applies to the CE-100T-8 only.) Use the VC4/VC LO Allocation tab 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. The CE-100T-8 has four pools, each with a maximum capacity of three STS-1s with SONET or three VC3s with SDH. All 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.

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 VC4s/VC LOs used by the circuit provisioned on the port. If the circuits provisioned are LO VCAT, there is a maximum of 63 VC12s with SDH.

  • Pool: Identifies the pool in which the VC4s/VC LOs are categorized. The ONS 15454 SDH CE-100T-8 card has four pools.

  • Refresh: Updates the POS Port Map area with current data.

Pool Utilization area

Displays the pool utilization information.

  • Pool: Identifies the pool number. The ONS 15454 SDH CE-100T-8 card has four pools.

  • Type: Displays the type of circuit the pool currently supports (VC4 or VC LO).

  • 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. If you provision VC12 VCAT circuits on SDH, you can create four circuits if the total members between all four circuits is less than or equal to 63.

  • Pool Usage: Displays the maximum number of VC4 or VC LOs per pool and the number of currently provisioned VC4 or VC LOs in the pool; for example, 1 of 1 VC4s or 63 of 63 VC LOs.

  • Pool Available: Indicates availability of the pool for the new circuit (Yes or No).

  • Help: Displays context-sensitive help.
