Strata DK Programming 5/99 3-169
System & Station
Program 78 Overview
This program assigns ground/loop start CO lines:
♦ to ring over external page during night mode
♦ to be used with DISA features
♦ for direct access to IMDU/RMDS modem
♦ for Auto Attendant operation
Feature 1: Ring Over External Page During Night Mode
This program selects which ground/loop start CO lines will activate ringing over external paging
facilities during the NIGHT mode (for Tenants 1~4). The NT Relay on the PIOU, PIOUS, or
PEPU will also be activated if it is in the 1-second ON/3-seconds OFF mode.
Feature 2: DISA CO Line Assignment
This program assigns ground/loop start CO lines to be used with the Direct Inward System Access
(DISA) features. These lines may be set for DISA operation during the different system modes of
DAY, DAY2, and NIGHT. A line will switch to normal ringing after ten seconds if the outside
caller does not use the DISA feature. Normal function of these lines occurs for outgoing calls.
Note An optional security code for DISA outgoing lines calls is available via Program 60-6.
This code should always be programmed when using DISA and built-in Auto Attendant to
prevent unauthorized calls through the DK system.
Feature 5: Ring IMDU or RMDS Maintenance Modem
The IMDU (DK40i and DK424 only) or RMDS (DK424 only) Remote Maintenance modem can
be directly accessed by incoming ground/loop start CO lines assigned in this Program. Different
alternatives are available for the system modes of DAY, DAY2, and NIGHT. If none of these are
selected, the IMDU or RMDS can still be reached by dialing a modem [DN] with the DISA feature
or by a Ring Transfer from the DSS console attendant or any other station. The IMDU or RMDS
modem must be enabled with Program 77-1, LED 14-ON.
Feature 6: Built-in Auto Attendant CO Line Assignment
This feature selects ground/loop start CO lines for Auto Attendant operation. There is no limit to
the number of lines which can be assigned with Auto Attendant. Different alternatives are
available for system modes DAY, DAY2, and NIGHT.
Built-in Auto Attendant is not available for Tie, DID, ANI or DNIS lines on DK40i or DK424 and
is not available on any line of DK14.
Note Auto Attendant assignments 61~63 have priority over ACD assignments in Program 14-0.
