i	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:

11.6 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!
i	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.
i	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/IIIa2//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.

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.
