Verifying ATM
Signaling Functions
Use the following procedure to verify ATM signaling functions:
1
Use the following command to check the UNI Version setting of your
ATM Backbone SwitchModule:
CB5000> show atm <slot>
interface
Examine the setting of the UNI Version parameter of the ATM
Backbone SwitchModule. It must match the ATM switch setting to
which it is connected. The valid settings are:
■
3_0
■
3_1
Contact your network supplier for the UNI version setting of the ATM
switch.
2
If necessary, reset the UNI Version parameter and corresponding ATM
signalling times using the following command:
CB5000> set atm <slot>
uni_version 3_1
(or
3_0
)

If you made any changes in Step 2, reset the module using the
following command:
CB5000> reset module <slot>
ATM commands do not take effect until you reset the module. Use the
DMM RESET MODULE command to enable any ATM parameter changes.
