Status of Network Control Data Channels
In order to perform maintenance testing on the Network Control DATA-CHLs, the
DATA-CHLs cannot be busy with one of the functions described previousl y. A
series of system technician commands can be used to determine if the
DATA-CHLs are busy and, if so, to determine the function for which t hey 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 determine the extensions for the
administered Network Control Data Channels (DATA-CHLs).
NOTE:
A Network Control Data Channel (DATA-CHL) is identified by a "type" value
of "netcon."
For each Network Control Data Channel (DATA-CHL) on the Active SPE,
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 be in service/active. However, the
form does not indicate the reason the DATA-CHL is busy. This must be
determined using other system technician commands.
Use the procedures below to determine whether busy Network Control Data
Channels (DATA-CHLs) are being 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 jour nal-printer
wakeup-log, busyout journal-printer pms-log, or busyout pms-link
command, respectively. Do not issue any of these busyout c ommands unless
instructed to do so while investigating Error Codes according to the "System
Technician-Demanded Tests: Descriptions and Error Codes" subsection. If one
of these links must be busied out to perform maintenance testing, restore the link
to service according to PRI-CDR/SEC-CDR (PRI-CDR Link),
PMS-PRNT/JNL-PRNT (PMS Printer Link), and PMS-LINK Maintenance
documentation, respectively.
If a DATA-CHL is busy but is not being used for one of these links, then it is being
used for a secondary administration terminal connection or for maintenance
testing. If it is being used for a secondary administration term inal connection,
then in order to test the DATA-CHL that the connection is using, the DATA-CHL
must be busied out using the busyout data-module <ext> command.
NOTE:
The busyout data-module <ext> command causes the connection over
the associated DATA-CHL to be dropped. Do not issue this command
unless instructed to do so.
