Paradyne 9128-II - Manual (Page 49)

3. Configuration
9128-A2-GB20-60 April 2002 3-15
NOTE:
If the default setting (1MPort or 1PPort) is not the setting required for your
application, change the Frame Relay Discovery Mode before connecting the
network cable or editing discovered option settings. Otherwise, the
FrameSaver unit will start discovering DLCIs as soon as it powers up.
If this occurs, you can recover by deleting the discovered DLCIs. If only a local
management PVC between the router and the FrameSaver unit has been
configured, simply select the desired Frame Relay Discovery Mode and Save
the change.
The default discovery mode, depending on model, is 1MPort or 1PPort.
When 1MPort mode is active, the unit creates for each DLCI discovered on the
network a multiplexed network interface DLCI (which contains two EDLCIs: one for
Port-1 data and the other for management), a standard Port-1 DLCI (with the same
number as the network interface DLCI), and a Management PVC, then
cross-connects them. When LMI is active on the network interface and PVC status
information (with provisioned DLCI numbers) is next received from the network,
the unit automatically saves the settings to the Current Configuration area.
When 1PPort mode is active, the unit uses the Network DLCI values obtained from
the Network LMI status response message to automatically configure for each
DLCI a corresponding DLCI for Port 1 having the same numeric value as the
Network DLCI, and automatically cross connects them. The DLCIs created on the
network side are IP Enabled (not standard or multiplexed) DLCIs. In addition,
payload management is configured for the network DLCI and assigned the Node
IP Address.
Configuration options set by selecting a discovery mode can be manually
modified, refined, or deleted at any time using the Configuration menus. No
previously discovered and configured DLCIs or cross-connections will be removed
unless authorized or Automatic Circuit Removal is enabled (see
Automatically
Removing a Circuit on page 3-16). Additional discovered DLCIs will be configured
according to the current Frame Relay Discovery Mode setting. Selecting or
changing the setting will not affect IP Addresses or Subnet Masks.
NOTE:
When auto-configuration creates a multiplexed DLCI, but a standard DLCI is
needed, change the DLCI to standard from the network DLCI Records screen:
