4Enter the number corresponding to the class of virtual circuit you want to define.

■If you want to create a standard VPC/VCC permanent virtual circuit to connect data ports, select [1] PVC and follow the instructions under “Adding PVC Virtual Circuits”.

■If you want to create a virtual circuit to support video conferencing, select

[2]RS366 Template and follow the instructions under “Defining RS366 (Video) Virtual Circuit Templates”.

■If you want to create a VCC virtual circuit to connect VCM ports, select

[3]VCM VCC and follow the instructions under “Adding Voice Compression Module VCC Circuits”.

■If you want to create a VCM subchannel circuit that bundles multiple DS0s, select [4] VCM Subchannel and follow the instructions under “Adding VCM Subchannel Circuits”.

Adding PVC Virtual To configure a VPC/VCC virtual circuit to connect data ports, follow these steps:

Circuits

1When you are prompted to select the virtual circuit type, as shown earlier in Figure 105, enter 1 to create a PVC circuit.

As shown in Figure 106, you are prompted to select a virtual circuit type.

Figure 106 Selecting the PVC Virtual CIrcuit Type: VCC or VPC

2Enter the number corresponding to the type of virtual circuit you want to configure:

VCC (virtual channel connection)—You can use this connection type for circuit between non-UNI and UNI cards and between UNI and UNI cards; both the VPIs and the VCIs will be translated.

VPC (virtual path connection)—You can use this connection type only for circuits between UNI and UNI cards; only the VPIs will be translated.

To operate a circuit as a VP, set the connection type to VPC.

A screen appears, listing the PathBuilder S330/S310 modules and ports by slot number and prompting you to select a slot for side A, as shown in Figure 107.
