Appendix E. Troubleshooting

Cannot pass data from T1 interface to V.35 port

Misconfiguration, improper cabling

•Verify that the T1 signal is being received. If not, check that the cabling is correct.

•Verify that the T1 is being received without errors. If not, double-check that framing and coding are set properly.

•Verify that desired dedicated map is active.

•Verify that bandwidth is mapped to the correct V.35 port.

•Verify that the V.35 port is set to the correct data rate (terminal inter- face).

•Check T1 performance using the terminal interface; if there are excessive errors, report fault to the Telco.

•Verify proper state of DTE signals via the terminal interface.

Switched calls are not working

Misconfiguration

•Verify that the endpoint has proper call accept/reject criteria. For RBS applications, check signaling bit status on the terminal interface for proper operation.

•Verify that the endpoint is set up for correct signaling.

Cannot communicate with ATLAS 550 using VT-100 connected to the Control/Chain In Port

Misconfiguration, improper cabling

•Check cabling, verify that the Control/Chain In port rate matches that of the attached terminal.
