Two-Way Audio

When using the D6600/D6100i for Two-Way Audio
(TWA) verification, use the Flash or Hold option
according to the central station Private Branch
Exchange (PBX) system, taking the D6600/D6100i off
line in a short period. If a PBX is not used, connect a
regular telephone in parallel with the incoming
telephone line. Once the D6600/D6100i is in Two-
Way Audio Mode, the operator can pick up the
telephone and undertake the two way audio operation.
Return the telephone to the receiver after the two-way
audio operation finishes.
The D6600/D6100i verifies the first digit of the account
code range 0 to F programmed in the Account Digits
option for the following communication formats:
•
Pulse (3 or 4 digit account code)
•
DTMF
•
BFSK
•
2
Modem II/IIIa
•
SIA
If the received account code is two-way audio enabled,
the line card goes into Two-way Audio Mode.
Programming a non-zero number in the Two Way
Audio Duration option affects all formats, and the
control panels cannot control the two-way audio
duration over the D6600/D6100i.
If the qualifying criteria apply, the D6600/D6100i
sends a signal to the automation firmware indicating
the physical line is in Two-Way Audio Mode. The line
remains off-hook for the time programmed in minutes
in the Two-Way Audio Duration option.
or
When the flash option is set for 1 to 20 (100 ms to
2 sec), the CPU first sends the two-way audio signal to
automation firmware. Then the line is flashed (quickly
disconnected and reconnected) for the programmed
flash duration. It remains off-hook for another 5 sec
then hangs up.
or
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 includes the
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's listen-in duration settings
override the control panel's 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/D6100i 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/D6100i 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.
