Notice!
Although it is not mandatory, not assigning a line to a call group, or when there is only one
line in the group, 1 min of busy time during a 10 min period results in a Busy Seconds Report.
If you do not assign a line to a call group, displays and printer reports identify the line number
instead of the Group number. A Line Busy Report shows and prints:
Two-Way Audio
When using the D6600/D6100IPv6 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/D6100IPv6 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/D6100IPv6 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.

Notice!
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 specif-
ic audio events used in SIA and Contact ID.

Notice!
D6100IPv6 Two-Way Audio was not investigated by UL.
The D6600/D6100IPv6 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
– Modem II/IIIa
2/
/4
– 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/
D6100IPv6.
If the qualifying criteria apply, the D6600/D6100IPv6 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.
