Result Description/Recommendation

4 ABORT For this test, an Error Code of 4 can have one of two different meanings:

a. The target DATA-CHL is busy and, therefore, not available for use.

b. Internal system error

Determine if the target DATA-CHL is in use for some other function (that is,

CDR Link, System Printer Link, Journal Printer Link, PMS Link, or secondary

administration terminal connection) as described previously in the "Status

of network Control Data Channels" section. If so, check for errors on the

function that is using the DATA-CHL. If there are no errors, there is a high

probability that the DATA-CHL is not defective. Proceed with the remaining

steps only if it is necessary to completely test the target DATA-CHL.

1. If the target DATA-CHL is in use for some other function, busyout the

function (PRI-CDR/SEC-CDR, SYS-PRNT, PMS-PRNT/JNL-PRNT,

PMS-LINK) or the DATA-CHL (secondary administration terminal

connection only).

2. Retry the command at 1-minute intervals a maximum of 5 times.

3. Restore any busied out PRI-CDR/SEC-CDR, SYS-PRNT,

PMS-PRNT/JNL-PRNT, PMS-LINK MOs to service before moving on to

another activity.

ABORT Internal system error

1. Retry the command at 1-minute intervals a maximum of 5 times.
