B-2 ATLAS 810

PLUS

User Manual 61200266L1-1

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.
