**********MAP SUMMARY**********
Maintenance Concepts For Modem Failure
This MAP is entered from Chapter 5 after the most probable cards
were replaced and the IML test 0111 is still failing. The MAP is
also entered from Chapter 2, step 8, Host Attachment Problem.
The Maintenance Concept is to run the resident integrated modem
self test whenever a flashing 3274 0111 code and display code of
0111 016 is indicated. If the self test fails, the failing card is
indicated via the led indicators on the A 1-02 card. The self test
and wrap test description and procedure is described in Chapter
5, Integrated Modem Section. The Host attachment and IML test
0111 MAP decisions will aid you in isolating other problems that
can cause an integrated modem failure, such as: internal external
cables, option wiring, incorrect card type, switch setting, power,
etc.
Is the IML test stopping at Code 01117
