Creating an ATM Circuit

In the NMC-RX application, you need to navigate to the ATM subinterface level to create an ATM circuit for the module.

To create an ATM circuit:

1. Navigate to the ATM subinterface in the list area.
2. In the list area, click a subinterface, right-click, select Create, and click ATM Circuit.

The Create ATM Circuit dialog box appears.

3. Set the ATM circuit parameters (Table 56).

 Table 56:  ATM Circuit Parameters

 NBMA Parameters

 Inverse ARP

 Enables InARP on the circuit


 ARP Refresh Rate (Min.)

 Specifies refresh rate for ARP in minutes; range 1-60


 OAM Settings

 Status

 Enables OAM F5 loopback cell generation on the circuit; enables VC integrity features that have an effect on the operational state of the ATM PVC


 Loopback Frequency

 Time interval in seconds between transmissions of OAM F5 loopback cells; range 0-600. If this option is not specified, OAM F5 loopback cells are generated once every 10 seconds.
