command. These extensions are called
active
extensions. When assigning an
active extension to a DATA-CHL XX (where XX is 01, 02, 03, or 04) the Add
Data-Module form also requires the user to assig n a unique

maintenance

extension. The maintenance extension is required.
1. Determine if CDR, System Printer, Journal Printer, and/or PMS Links are
using the DATA-CHLs and busyout these links if it is necessary to us e the
test network-control long command.
2. Refer to ‘‘SW-CTL (Switch Control)’’ Maintenance documentation before
executing the reset switch-control c ommand to determine the
consequences of running the Switch Control Reset Test (Test #93).
3. Refer to ‘‘IO-PROCR (I/O Processor)’’ Maintenance d ocument before
executing the reset io-processor c ommand to determine the
consequences of resetting the IO Processor.
Status of Data Channels
In order to perform maintenanc e testing on the DATA-CHLs, the DATA-CHLs
cannot be busy with one of the func tions described previously. A series of system
technician command s can be used to d etermine if the DATA-CHLs are busy and,
if so, to determine the function for whi ch they are being used . This series of
system technician commands is described below and should be done before
testing the DATA-CHLs.
Issue the list data-module command to deter mine the extensions for the
administered Data Channels.
NOTE:
A Data Channel is identified b y a "type" value of "netcon."
For each Data Channel, determine if the DATA-CHL is busy by issuing the status
data-module <ext> command using the DATA-CHL’s extension. If the DATA -CHL
is busy, the Service State field in the resulting form will b e in service/active.
However, the form does not indic ate the reason the DATA-CHL is busy. This must
be determined using other system technician c ommands.
Use the procedures be low to determine whether busy Data Channels are b eing
used for CDR, Journal Printer, or PMS Links. If a DATA-CHL is busy with one of
these links then, in order to test the DATA-CHL, the link must be busied out using
busyout smdr-link, busyout journal-printer wakeup-log, busyout
journal-printer pms-log, or busyout pms-link command, respectively. Do not
issue any of these busyout command s unless instructed to d o so while
investigating Error Codes acc ording to the "System Technician-Demanded Tests:
Descriptions and Error Codes" subsec tion. If one of these links must be b usied
out to perform maintenance testin g, restore the link to service acc ording to
PRI-CDR/SEC-CDR (PRI-CDR Link), PMS-PRNT/JNL-PRNT (PMS Printer Link),
and PMS-LINK Maintenance documentatio n, respectively.
