Begin the T1 configuration by accessing the WAN Physical Configuration screen through Local Management (Figure 3-1). Access the WAN Physical Configuration screen from the WAN SETUP menu item in the host platform.

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.

2.Use the arrow keys to highlight MgrType. Select PPP.

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.

3.Use the arrow keys to highlight Timeslot View. Press the SPACE bar to select New, then press ENTER. The cursor moves to Timeslot #1 of the Timeslot Configuration Table.

4.Insert an interface number (refer to NOTE below) into every timeslot as needed. Type the number, press ENTER, then use the arrow keys to highlight the next timeslot field. Exit this field by using the arrow keys. The cursor automatically moves to the T1 Line Coding field.

NOTE

The value assigned to the timeslots is the interface being used for WAN communication. The next available interface is displayed on the WAN Physical Configuration screen in the Next IF field (seeFigure 3-1). The Next IF number shown must be used to add a new interface. The Next IF will increment as interfaces are added. The previously entered interfaces can be modified by entering the interface number.

The following four steps are based on information supplied by the service provider. Consult the service provider for the correct settings.
