User Manual 61200226L1-1

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.
