Configuring SPVCs
A permanent virtual circuit (PVC) is established administratively (that is, by network
management) rather than on demand (that is, using signaling across the UNI). A soft
PVC (SPVC) is established by the network using signaling. Once the SPVC
configuration is in place, the switch at one end of the SPVC initiates the signaling.
This release supports up to 4096K SPVCs per card.
The NMS provisions one end of the SPVC with the address identifying the egress
interface from the network. The calling end has the responsibility for establishing,
releasing, and re-establishing the call.
Supported Modules
SPVCs are supported on the following ATM modules:
