Troubleshooting interoperability

This section covers the following ATM interoperability topics:

■Physical connections—Checks for correct ATM installation and configuration

■Administration—Checks for correct DEFINITY ECS and ATM switch administration

■TN2305/TN2306 circuit pack—Checks LED status, circuit pack insertion, and demand tests

■ATM signaling architecture—Checks the interoperability between the DEFINITY ECS switch and the ATM switch

Because Lucent offers a variety of ATM switches, this discussion suggests general rather than specific diagnostics.

Physical connections

Has the ATM switch been installed and configured correctly?

Diagnostics

■Is the ATM switch powered up?

■If you are administering the ATM switch through a locally attached console, is there a local console terminal connected to the console port on the ATM switch processor circuit pack with the correctly pinned RS232 serial cable?

■If you are administering the ATM switch through telnet over the Ethernet, is there an Ethernet drop plugged into the Ethernet port on the ATM switch processor board? (Note that a few ATM switch commands are only permitted over the local console terminal.)
