Configure primary PVPCs and backup PVPCs using the command-line interface. Backup
PVPCs are redundant to primary PVPCs. A primary PVPC automatically switches to a backup
PVPC if the primary PVPC were to fail.
PVPCs carry data between defined points within the Avidia chassis, such as between a
cell-based channel card and a line card. PVPCs also carry data from subscriber modems to
Avidia channel cards, and from Avidia line cards to other destinations in the ATM backbone
network.
PVPC configuration requires specifying a Virtual Path Identifier (VPI). For PVPCs, the system
only translates the VPI value and does not check or change any configured Virtual Channel
Identifier (VCI) value.
