DAT-LINE (Data Line Port)
The TN726 Data Line circuit pack has 8 ports, each of which supports an RS-232
interface to asynchronous Customer Premises Equipment (CPE). Each of these
ports and the equipment connected to it constitute a data line. For DT-LN-BD
(Data Line Circuit Pack) errors, refer to "XXX-BD (Common Port Circuit Pack)".
Check circuit pack-level errors first since the usability of the ports depend on the
health of the circuit pack.
Data line ports are administered at the terminal with the
add data-module
command. The data module type is
data-line
. The
list data-module
command
will list all administered data modules in the system. See “PDATA-PT” for details
on how data lines are used as system ports.
The TN750 Announcement circuit pack also has one data line-type port on it.
This data line port is used for saving and restoring announcements. For a
description of this feature and repair instructions for the TN750, refer to
“ANN-BD”.
NOTE:
If the tests for the data line port in question pass, and user-reported
complaints persist, there is probably an external problem. Test the
asynchronous data unit (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 then check the
customer equipment.
