Busy Seconds (Line Busy) Reports

The D6600 Receiver software monitors and reports
when a call group of receiver lines cannot receive
signals. The receiver cannot process signals if its
incoming telephone lines are in trouble, if other
communicators have the line tied up, or if the line card
is inoperative. The receiver interprets these conditions
as busy time.
The amount of busy time accumulated during a 10 min
period is the basis for a Busy Seconds Reports. The
10 min busy period begins when all lines in a call
group become busy, or when a non-programmed single
line for a call group becomes busy. The D6600 totals
the accumulated busy time and prints the Busy
Seconds Report after the 10 min period ends. After at
least 60 sec (10%) of busy time, the receiver generates a
report. The D6600 reports up to 100% busy time.
Program the Busy Seconds Reports option to No if
Busy Seconds Reports are not wanted for all lines.
Setting the Line Sniff option to 2 disables reports for
individual lines.
Set Busy Seconds Reports to Yes for UL
Listed central stations.
UL inspectors might investigate the amount of time the
digital receiver lines cannot receive signals. Ensure
lines are available to process emergency signals on a
timely basis. Excessive Line Busy Reports can indicate
it is necessary to install additional lines in rotary with
your primary receiver lines.
Assign each line to a call group. For the group to start
accumulating busy time, all lines in the call group must
be online, in trouble, or without an operating line card.

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 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 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 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 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.
Program a non-zero number in the Two-way Audio
Duration option. This option affects all formats, and
the control panels cannot control the two-way audio
duration over the D6600.
If the qualifying criteria apply, the D6600 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.
