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”.

n

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”.

n

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”.

n

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”.

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

1 When 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

2 Enter 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.

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.
