Appendix B. Troubleshooting
B-2
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 excessive errors,
report fault to the Telco.
•
Verify proper state of DTE signals via the terminal interface or the LCD
front panel.
Switched calls are not working
Misconfiguration
•
Verify that the end point has proper call accept/reject criteria. For RBS
applications, check signaling bit status on the terminal interface for
proper operation.
Verify that the end point is set up for correct signaling.
Cannot communicate with ATLAS USING VT-100
connected to the Control/Chain In Port
Misconfiguration, improper cabling
•
Verify that ATLAS is receiving commands (press keys on terminal and
verify that the received byte count in the front panel increments).
•
Check cabling, verify that the chain port rate matches that of the at-
tached terminal; check chain port status leads on the front panel.
