Inspecting LEDs

To get a high-level status of the system, observe the LEDs on the TN2305/TN2306 ATM interface circuit packs and the ATM switch. For information on interpreting the LEDs on the ATM switch, refer to your switch’s quick reference guide. For information on interpreting the LEDs on the TN2305/TN2306 circuit packs, refer to the following books:

■DEFINITY Enterprise Communications Server Release 8 Maintenance for R8r

■DEFINITY Enterprise Communications Server Release 8 Maintenance for R8si

■DEFINITY Enterprise Communications Server Release 8 Maintenance for R8csi

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 may only be permitted over the local console terminal.)
