PVC Management Interworking Sample Clauses

PVC Management Interworking. On the Frame Relay side of the IWF, the PVC management procedures are as defined in ITU-T Recommendation Q.933 Annex A (See Figure 2 below). The procedures must be bidirectional to facilitate transport of status indications in both directions. Support of asynchronous status messages is optional. On the ATM side of the IWF, the PVC management procedures are based on mechanisms provided in the ATM Forum UNI 3.1 and B-ICI 1.1. The IWF will receive indications from the Frame Relay network and map them to the corresponding ATM indications and then send them to the ATM network. Likewise, the IWF will receive indications from the ATM network and map them to the corresponding Frame Relay indications and then send them to the Frame Relay network.
