STS/VT Allocation
Use the STS/VT 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-MR-6 and CE-MR-10 cards have 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 VT VCAT circuits, if sufficient bandwidth exists to support the STS circuits on the remaining three pools. To help prevent stranding bandwidth, provision your STS VCAT circuits first to distribute them evenly.
 
Item
Description
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 VT VCAT, there is a maximum of 84 VT1.5s with SONET.
First STS: Identifies the first STS number that the circuit uses.
First VT: Identifies the first VC VT number that the circuit uses. This only applies to VT circuits.
Retrieve: Updates the POS Port Map area with current data.
STS Map area
Displays the pool utilization information.
STS: Identifies the STS number.
Pool: Identifies the pool number.
Type: Displays the type of circuit the pool currently supports (STS or VT).
Port: Displays the port number.
Next STS in VCG: Identifies the next STS number in the VCG group.
Help: Displays context-sensitive help.
