DATA-CHL (Data Channel)
From the viewpoint of administration, the four DATA-CHLs on the TN2402/TN798
Processor circuit pack are numbered 01 through 04. Each DATA-CHL may be
assigned a unique extension using the add data-module [ <ext> | next ]
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 assign 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 use the
test network-control long command.
2. Refer to ''SW-CTL (Switch Control)'' Maintenance documentation before
executing the reset switch-control command to determine the
consequences of running the Switch Control Reset Test (Test #93).
3. Refer to
executing the reset io-processor command to determine the
consequences of resetting the IO Processor.
Status of Data Channels
In order to perform maintenance testing on the 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 Data Channels.
NOTE:
A Data Channel is identified by 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 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 Data Channels 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.
