Selecting a Frame Relay Discovery Mode
When a Frame Relay Discovery Mode is active, the FrameSaver unit “discovers”
network DLCIs from the network LMI status response message. It configures a
network DLCI, a user data port DLCI, and automatically connects them to create
a PVC.
Main Menu →Auto-Configuration →Frame Relay Discovery Mode
Automatically configured network DLCIs are multiplexed, and each automatically
configured port DLCI carries the same DLCI Number as its corresponding
network DLCI. These are the same DLCI numbers that would have been
available had the FrameSaver unit not been inserted in the link, between your
equipment and the network.
NOTE:
A local Management PVC (e.g., the PVC between the router and the
FrameSaver unit’s user data port) must be configured manually; it cannot
be configured automatically (see Setting Up Local Management at the
Central Site).
The following will occur when a Frame Relay Discovery Mode is selected:
