CONFIGURING PVPCS
Configure PVPCs from the PVPC Configuration Table window. From this window, you can
optionally configure backup PVPCs for the primary PVPCs.
Backup PVPCs are redundant to
primary PVPCs. A primary PVPC automatically switches to a backup PVPC if the primary
PVPC were to fail. Do one of the following to open the
PVPC Configuration Table window:
• In the
Site Map Navigation window, click ATM then PVPC Configuration Table.
• In the
Tree Navigation window, click Configuration Management, ATM, then PVPC Configuration.
The
PVPC Configuration Table window displays.
PVPCs carry data between defined points within the Avidia chassis, such as between a
cell-based channel card and a line card (see “Configuring PVCCs” on page 443 for creating
cross-connects from a frame-based channel 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.
