Description: This module contains Alcatel's proprietary MIB definition for managing point-to-point and point-to-multipoint Permanent Virtual Connections (PVCs).

The MIB supports the creation, modification, query and deletion of PVCs (Permanent Virtual Connections) on Cell Relay endpoints, both Permanent Virtual Path Connection (PVPC) and Permanent Virtual Channel Connection (PVCC) are supported. PVPCs are defined by nncCrPvpcTable and PVCCs are defined by nncCrPvccTable.

PVPCs or PVCC's connecting different endpoint types, CR to FR, FR to CR, CR to CE, CE to CR, CE to FR or FR to CE are not suppported at this point. Resource connections such as Signalling, PNNI, ILMI and CPSS are also not supported.

PVCs can be created by one of two ways: using rowStats as 'createAndGo' or using rowStatus as 'createAndWait'+'active'.

In some cases, to create a PVC via this table requires two SET-REQs, because one SET-REQ PDU cannot fit all required objects. In these cases, the rowStatus is set to createAndWait(5) for the first 1 SET-REQ and set to active(1) for the last SET-REQ.

In some cases, all required MIB objects can fit in one SET-REQ PDU. In these cases the rowStatus should be set to createAndGo(4)

To delete a PVC, the SNMP manager should set rowStatus of the PVC instance to 'destroy'.

Each PVC is modeled as set of entries in the PVC table. A point- to-point PVC is modeled as one entry; a point-to-multipoint (N leafs) is modeled as N entries in this table. The N entries of a point-to- multipoint PVC shares the same source end point.
