Configuring ATM PVCs
Configuring Frame Relay-to-ATM Interworking Circuits
VCI (1..nnnn)
(ATM endpoint 
only, VCCs only)
Enter a value to represent the VCI for an ATM circuit. See 
page 10-9 for information about setting this value.
When you configure the ATM circuit:
• On a Frame-based IOM, enter a value from 32 to 63.
• On an ATM-based IOM (such as the ATM DS3 module), enter 
a value from 32 to 255.
•On a 
1-port ATM CS DS3/E3 and 1-port ATM IWU 
OC-3c/STM-1
 module, the total number of bits available for 
the VPI and VCI is 12 bits. For example, if the VPI is set to 1, 
there are 11 bits available for the VCI. If the VPI is set to 2, 
there are 10 bits available for the VCI.
Note: If you are configuring the VCI on a 
1-port ATM CS 
DS3/E3
 or 1-port ATM IWU OC-3c/STM-1 module, the 
VCI range depends on the number of VPI bits selected on the 
physical port. See the Switch Module Configuration Guide 
for CBX 3500, CBX 500, GX 550, and B-STDX 9000 for 
more information.
• For FRF.5 network interworking, enter a value from 1 to nnn 
to represent the VCI for an ATM circuit.
Endpoint 
Connection ID: 
DLCI 
(Frame Relay 
endpoint) 
Enter a unique DLCI for this logical port.
Management 
Circuit
If you select this check box, this PVC configuration will be 
included in the NMS initialization script file. This file contains all 
the SNMP set requests necessary to replicate the entire switch 
configuration. Once you download this file to the switch, this 
PVC can be used to establish NMS-to-switch connectivity. This 
option is especially useful in some management configurations. 
Clear the check box to disable this feature (default).
Is Template 
(Optional) 
You can save these settings as a template to configure another 
PVC with similar options. To create a template, select the check 
box in the Template field. Clear the check box to disable (default). 
See “Using Templates to Define Circuits” on page 10-92 for more 
information.
