When the Hold option is set for 1 to 99 sec the line
card remains off-hook for the programmed hold after
sending the audio event signal to the automation
firmware, allowing the firmware controlled PBX to
pick up the line. Then it hangs up.
10.6.1 Enhancements and Changes
• Setting TWA by the selected Alarm Code allows
one or multiple Alarm Codes to be selected. TWA
works with 10 to 40 baud Pulse formats, DTMF
4/1, 4/2, 4/3 and Contact ID formats
• Setting TWA by the selected zone number allows
the selection of one or multiple zone numbers.
TWA works with 10 to 40 baud formats and
DTMF 4/1, 4/2 and 4/3 formats.
The zone number is the last digit of events
that activates the TWA function.
• TWA by combined conditions include account
number, alarm code, and zone number
• Supports TWA auto-entered by more events and in
various protocols, including Contact ID Event
Code 606, and SIA control blocks.
When the line card is in Two-Way Audio Mode, it
only goes on-hook when the operator presses [CAN] ,
or the automation firmware issues a Stop Listening
Command !Knn<CR>, where nn is the physical line
number.
The maximum on-line time during two audio
sessions is disabled.
The line card listen in duration settings
overrides any control panel listen in
duration settings.
When pressing [CAN] during the two-way audio
session, the receiver prompts the operator to enter the
line number for stopping the two-way audio. Ensure
the D6600 is not in Menu Mode during this operation.
The OL/LF LED flashes green during the audio
session.
The D6600 prints the audio status on the printer with
the physical line number and sends the audio status to
the automation firmware with the physical line
number.
The D6600 decodes the first digit of the account
number to determine when to start two-way audio
operation. If the first digit of the account number
matches the selection, two-way audio activates.
10.6.2 Two-Way Audio Modes of Operation
• Transfer: D6600 transfers the incoming line to
another line; a flash operation occurs at the end of
the alarm signal. The receiver dials the line
programmed at Transfer Phone Number (refer to
Menu Items 3.1.4.18 Flash [x 100ms] and 3.1.4.19
Transfer Phone Number in the D6600 Program Entry
Guide [P/N: 4998122702]).
• Hold: The D6600 remains off-hook as
programmed so another device can take over the
line before hold time expires. Refer to Menu Item
3.1.4.20 Hold in the D6600 Program Entry Guide
(P/N: 4998122702) to program.
• Duration: The D6600 remains off-hook as
programmed or until terminated by a Stop
command. Connect a regular telephone in parallel
with the incoming telephone line. Refer to Menu
Item 3.1.4.1 Duration in the D6600 Program Entry
Guide (P/N: 4998122702) to program.
The D6600 can only perform one of these
operations at a time. If there is more than
one, the sequence is Transfer, Hold, and
Duration.
