4. First, program the pause time (used with speed dial). Highlight Pause Time and press Enter to view your
choices. Valid options are from 0.5 to 7.0 seconds. The default is 2.0 seconds.
5. Next, program the auto pause insertion time (used with PBX type CO line ports). Highlight PBX Auto
Pause and press Enter to view your choices. Valid options are from 0.5 to 7.0 seconds. The default is 1.0
second.
6. When you are done, press Esc to return to the Database Programming screen. The system prompts: “Exit
This Feature?”; press Y for yes.
7. The system prompts “Save Current Setting?” Press Y to save your changes.
8. The system then prompts “File Exists, Override?” Press Y to continue with the save operation.
9. Press Esc to return to the Database Programming menu.
10. When you have finished all programming changes, perform a Send operation to copy your new database to
the DX-80 switch system memory. For more details, see Section 2.1.4.4, F4 – Send .
6.6 Specifying Ring Abandon
The system allows you to set the ring abandon time. Ring abandon is the interval the system waits for the next ring
before classifying the call as dropped from the CO trunk.
Typically, CO ring cycles include one second of ring (voltage) followed by three seconds of no ring (removal of
voltage). It is possible for COs to vary from this pattern, and if your customer’s CO does you may have to adjust
the default ring abandon setting. A longer ring abandon gives the system more time to realize the absence of CO
trunk ringing, but while the system waits it continues to ring the extension. If in fact the call has been dropped by
the trunk, the extension user can receive dial tone when picking up a ringing line.
The ring abandon time starts when the CO trunk ring (voltage) occurs, and includes the interval after the ring
(removal of voltage). So, if the CO is using the 1/3 pattern, a ring abandon time of 10 seconds means the system
will wait another 6 seconds for a ring (voltage) to occur before classifying the line as a ring abandon and stopping
the system ring at the extension (1 second ring + 3 seconds no v 6 additional seconds no voltage = 10
seconds).
