3Enter the desired port number.

■If you are setting up point-to-point video conferencing (between remote PathBuilder S330/S310 switches).

■Enter 4 to select the serial (V.35) port.

■If you are setting up multi-point video conferencing (both between remote PathBuilder S330/S310 switches and between remote PathBuilder S330/S310 switches and a central PathBuilder S330/S310 switch).

■For the remote units, enter 4 to select the CBR serial (V.35) port.

■For the central unit, enter 1, 2, or 3 to select one of the CBR T1-DSX/E1 ports.

The Add Virtual Circuit screen lists the parameters you will enter for side A of the circuit template and prompts you to set the first parameter. See “CBR Module Virtual Circuit Parameters”, later in this chapter, for parameter descriptions.

4Follow the prompts that appear at the bottom of the screen, pressing [Enter] after each entry.

Your settings are added to list of parameters at the top of the screen as you enter them. You must enter a setting for all the parameters for which you are prompted in order to add a circuit template. Press [Delete] to back up to a previous selection.

When you have completed side A of the circuit template by entering a setting for each parameter, the Add Virtual Circuit screen displays a list of PathBuilder S330/S310 modules that you can use for side B of the circuit template.

Figure 112 shows the Add Virtual Circuit screen with side A completed for a video virtual circuit template using the CBR serial port. Figure 113 shows the Add Virtual Circuit screen with side A completed for a virtual circuit template using a CBR T1-DSX/E1 port.
