Modem 3600 D-1

Appendix D

Fault Isolation Procedure

This diagnostic test procedure and the indicator lights built into the

modem allow a rapid check of the terminals, modems, and telephone line

interface. This procedure can be used to verify normal system operation

and to isolate faulty equipment in case of failure.

Ensure the units are turned on and remote loops are enabled at both sites

before starting the fault isolation procedure.

Note

In some cases the observer must distinguish between rapid LED

blinking and steady on in tests.

Telephone Interface

1) Connect the modem to the dial-in line by the LINE jack on the back

panel.

2) If the dial line is installed with a standard data jack, connect a

standard telephone to the TELSET/LEASED LINE jack on the

back panel of the modem and use the standard telephone procedure.

Standard Phone

1) Configure the modem to V.34 33600 IDLE mode by pressing the

TALK/ DATA button, and then lift the receiver. No dial tone is

heard. Press the TALK/DATA button to display V.34 IDLE and

wait for dial tone.

2) Dial out; the phone should operate normally.
