LINESHARE MASTER
6. Calculating the Timing Parameters
The total of these calculations is
equal to the length of time that the
Lineshare Master stays on line after
a phone number is dialed.
In the above example, the
Lineshare Master will drop the line
about 35 seconds (34.5) after the
phone number was dialed. If the
modem is on line for 40 seconds
after dialing, the two systems will
function properly.
If you are on an extension phone
and the Lineshare Master is active, at
the end of a phone number you can
enter the # # command to turn the
unit OFF. When you are ready for
the Lineshare Master to transmit the
tones again, enter # * at the end of a
phone number. This reactivates the
Lineshare Master to start
transmitting the tones.
For the best performance from the
system, set the Lineshare Master to
stop sending tones and drop the line
five seconds before the fax or
modem time-out period expires.
If a modem dials a phone number
through the Lineshare Master and
the modem stays on-line about 45
seconds, the Lineshare Master
should stay on-line for 40 seconds of
the call. This allows the Lineshare
Master to have the best chance of
routing a call to the proper device.
If adjustment to any of the timing
registers is necessary, it is important
to have the proper calculation to
ensure that the Lineshare Master
drops the line about five seconds
before the calling device. To
calculate the timing parameters,
perform the following steps:
1. Multiply the Tone Time (TT)
and the Number of Tones (NT):
0.5 seconds x 8 tones=
4 seconds
2. Multiply the Silence Time (ST)
and the Number of Tones (NT):
3.5 seconds x 8 tones= 28
seconds
3. Add these two totals together:
4 + 28 = 32 seconds
4. Add the total from #3 to the
Time Before First Tone (TBFT)
and two seconds for the tone
detection timer:
32 s 0.5 seconds (TBFT)
+ 2.0 seconds= 34.5 seconds
