4 Enter 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
n
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
n
[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
n
[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,
n
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.
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.
