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 previously. 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 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 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 journal-printer
wakeup-log, busyout journal-printer pms-log, or busyout pms-link
command, respectively. Do not issue any of these busyout commands 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 terminal 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.
