10.6 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 for a short period. If a PBX is not used, connect a
regular telephone in parallel with the incoming
telephone line. When 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.
D6600 Two-Way Audio (TWA)
verification is fully supported using the
D6641 line card. The D6640 does not
support option 3.1.4.21 Audio Event,
3.1.4.22 Audio Zone, or protocol specific
audio events used in SIA and Contact
ID.
D6100i Two-Way Audio was not
investigated by UL.
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
22
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
goes on-hook only 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 online 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 that the D6600/D6100i 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.
