DAT-LINE (Data Line)
The TN726 Data Line circuit pack is a port circuit that provides connectivity from
the system to asynchronous CPE having RS232-compatible serial interfaces.
There are eight data lines (DAT-LINEs) on the Data Line circuit pack. If there are
errors associated with the DT-LN-BD (Data Line Circuit Pack), refer to the
XXX-BD (Common Port Circuit Pack) Maintenance documentation.
Data Lines are administered via the administration terminal add data-module
command. The data module type is
data-line . The list data-module command
lists all administered data modules in the system.
The TN750 Announcement circuit pack has one Data Line on it. The Data Line is
used for saving and restoring announcements. For a description of this feature,
refer to ANN-BD (Announcement Circuit Pack) Maintenance documentation.
Also, if there are errors associated with the Announcement circuit pack, refer to
the ANN-BD Maintenance documentation.
NOTE:
If the tests for the Data Line in question pass and there are still
user-reported problems, there is probably an external problem. Test the
ADU, following the procedures outlined in
User Manual Z3A Asynchronous
Data Unit
, 555-401-701. If the ADU appears to be working properly, check
the external wiring and, finally, check the customer equipment.
1. Where P is the port network number (1 for PPN and 2 or 3 for EPN); C is the carrier
