DAT-LINE (Data Line)
The TN726 Data Line circuit pack is a por t circuit that provides connectivity from
the system to asynchronous CPE having RS232-compatible seria l interfaces.
There are eight data lines (DAT-LINEs) on the Data Line circuit pack. If there are
errors assoc iat ed wi th the DT-LN- BD (Da ta Li ne Circ uit Pack) , refer to th e XXX-BD
(Common Port Circuit Pack) Maintenance doc umentation.
Data Lines are administered via the adm inistration terminal add data-module
command. The data module type is
data-line . The list data-module command
lists all administered da ta modules in the system.
The TN750 Announcement circuit pac k has one Data Line on it. The Data Line is
used for saving and restoring announcements. For a desc ription of this feature,
refer to ANN-BD (Announcement Circuit Pack) Maintenanc e documentation.
Also, if there are errors associated with the Announc ement circuit pac k, refer to
the ANN-BD Maintenance doc umentation.
NOTE:
If the tests for the Data Line in question pass and there are still
user-reported prob lems, there is probably an external problem. Test the
ADU, following the proced ures outlined in
User Manual Z3A Asynchronous
Data Unit
, 555-401-701. If the ADU appears to b e working properly, chec k
the external wiring and, finally, chec k the customer equipmen t.
