Chapter 3: Local Management for T1 Service

3.5.2Frame Relay Interface Configuration

Access the WAN Interface Configuration screen through the WAN Physical Configuration screen, by using the arrow keys to highlight the WAN INT CONFIG command, then press ENTER. Proceed with the following steps to configure the WAN Interface.

1.Set the Interface Number that is being used for the WAN connection by typing the same number into the Interface Number field that was input into the timeslots in the WAN Physical Configuration screen, then press ENTER (refer to the Note on page 3-19).For Frame Relay PtoP, the interfaces are assigned when DLCIs are created (in this case a zero needs to be entered in this field).

2.Use the arrow keys to highlight FR LMI. Press the SPACE bar to select ANSI_94, T1.617-Dor Q.933-A, then press ENTER.

NOTE

The choice NO LMI under FR LMI is a test mode only and should not be used in a practical application.

3.Make any changes to the available settings as desired.

4.Use the arrow keys to highlight SAVE, then press ENTER. The message “SAVE DONE!” displays and Local Management saves the changes to memory.

In FR PtoP, the DLCIs must be entered statically, as they will not come up dynamically as in FR PtoMP.

In FR PtoMP, there is an option to statically enter the DLCIs in association with a Protocol Manager, the physical port and MIB II, using the DLCI field in the Interface screen. If the DLCI is not static, it will be deleted if the Frame Relay switch determines that the DLCI has been eliminated. If the Frame Relay switch previously reported status on a DLCI, when it does not report the status of the DLCI, the DLCI and its associated information is deleted from the platform. Static entries are never deleted automatically. They must be deliberately deleted by the user. To enter a DLCI, it is set to “Inactive” and saved, but to delete a DLCI, it must be accessed and entered as “Invalid” and saved.
