3.5.1Frame Relay Physical Configuration

Begin the WPIM-T1/DDS physical configuration by accessing the WAN Physical Configuration screen through Local Management (Figure 3-1). Proceed with the following steps:

1.Use the arrow keys to highlight the WPIM X field at the bottom of the screen. Press the SPACE bar to select the number of the WPIM to be configured, then press ENTER.

Use the arrow keys to highlight the MgrType field. Configure Protocol Manager Type as either FR PtoMP or FR PtoP. There are two settings for Frame Relay, Point to Point (FR PtoP) and Point to Multipoint (PtoMP). Frame Relay Point to Point has one Interface per DLCI assigned when DLCIs are created by the Service Provider. In Frame Relay Point to Multipoint, there is one interface to multiple DLCIs, and the DLCIs are dynamically learned. Backup can only be run on FR PtoP, not FR PtoMP.

NOTE

When changing from one protocol to another on a WPIM-T1/DDS that has been operational, save NONE as the protocol before changing to another protocol.

2.Use the arrow keys to highlight Timeslot View. Press the SPACE bar to select New, then press ENTER. The cursor moves to the first timeslot available in the Timeslot Configuration Table.
