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.

ATM settings for the OC3 line card, which may be useful when configuring virtual circuits.
