Terminating Calls
Calls may be terminated in one of three ways:
• When there are no Page/Party
®
handsets off-hook on the designated party line, the TI984 disconnects
from the telephone line after a programmable delay. See the Programming Procedure section (page
7) for details.
• Pressing the RESET button on the front panel of the TI984 or a remote RESET button immediately
disconnects the TI984 from the telephone line.
• If the incoming telephone line is equipped with the Loop Current Disconnect feature, the TI984
automatically disconnects from the telephone when the outside caller hangs up the telephone.
Number of Incoming Rings
This function sets the number of rings (1 to 10) that the TI984 waits before answering incoming calls. If
you want to give the operator a chance to pick up the call before the TI984 responds, you may want to
program a fairly high number of rings.
The number programmed into the unit (0 to 9) sets the delayed number of rings before the unit answers.
For example, if 0 is programmed as the delay for the incoming rings, the unit answers after the first ring
(programmed number plus 1). If 4 is programmed, the unit delays 4 rings and answers after the fifth ring.
Hang-up Delay
This parameter sets the time that the TI984 pauses between the time when the Page/Party
®
station goes
on-hook and the call is disconnected. If the delay is set to 0, the TI984 disconnects the call when the
Page/Party
®
station goes on-hook.
However, the hang-up delay can be set at 15 seconds or higher if, for example, the Page/Party
®
user needs
to page a third individual but does not want to disconnect the telephone call. At this setting, the user has
15 seconds to make a page and get back to the page line without disconnecting the call.
Universal Parameters
The following parameters remain the same in both day and night modes. They can be set in either mode,
and do not need to be set again when programming the parameters for the other mode.
Internal/External Day/Night Switch
Determine if an internal or external (remote) switch will control the day/night mode, and make the
appropriate selection. If the user plans to operate the Day/Night switch located on the front panel of the
TI984, then INTERNAL should be chosen. This momentary switch toggles the unit between day and night
modes. The user may watch the LED located next to the switch to determine the unit mode. Steady on or
steady off means the unit is in day mode, while a blinking LED means that the unit is in night mode.
To operate the day/night mode remotely, wire a two-position switch and select the EXTERNAL mode. This
is to ensure that the day and night modes can be marked on the remote switch.
