2.5ACS-FRS Card Troubleshooting

Problems with a FRS card could indicate a number of causes. Some possibilities are:

•T1 or E1 network failure

•Improper frame relay network configuration

•Improper FRS card configuration

•Improper user card configuration

•Faulty cabling between the DTE and user card

•Improper DTE configuration

Typically, a problem is indicated by the inability to send or receive frame relay traffic through the FRS card. There are numerous ways of isolating and clearing the problem. When troubleshooting frame relay communications problems through an FRS card, follow this general sequence:

1.If all Frame Relay traffic is affected, verify that the US/EUR jumper is correctly placed to match the US/EUR jumper on the chassis. The FRS card performs a self-test on power-up. A “healthy” card will have a green LED lit on the front panel. Do not proceed with further steps until a green LED is present.

2.Verify that the T1 or E1 network is working properly by checking for current CGA-Red and CGA-Yellow alarms (see Chapter 3-A for alarm viewing instructions). If no CGA alarms are present that would affect the frame relay traffic, continue with step 3.

3.Verify that the FRS port is connected to the proper WAN card and time slot or user card port and that the correct type of LMI is selected. If a user card port is used, verify the configuration settings on the user card port and the cable connection to the DTE. The LMI must be UP for data to flow on the circuit. Do not proceed with further steps until the LMI is up.

4.Go to the Port Performance Monitoring Screen by pressing P from the FRS Main Screen. Analyze the register and status information provided to help determine the cause of the problem.
