5.2.3 SYSTEM DATA

DIALING MODE

Select the dialing mode to agree with the user's type of line.
• TONE: Dialing using tones
• PULSE: Dialing using pulses

MODEM SPEED

You can set the maximum modem speed.
During call setup, the baud rate is automatically adjusted to agree with the slowest
device. Keep the default at 33.6 Kbps.
Only adjust this where the local line conditions are extremely poor.

ERROR RATE

The baud rate automatically goes to 2400 bps when the error rate is not the same
as the set value. This keeps the error rate below the set value.
You can set the rate between 5% and 10%.

SET TX LEVEL

You can set the level of the transmission signal. The Tx level must be less than -12
dBm.
CAUTION: The send fax level is set at the factory. Do not change this in the field.

SILENCE TIME

In ANS/FAX mode, after a call is picked up by the answering machine, the machine
monitors the line. If a period of silence is detected on the line, the machine
processes the incoming call as a fax message and the machine begins to receive.
You can select a silence detection time between limited (about 12 seconds) and
unlimited time.
When "12 sec" is selected, the machine switches to receive mode immediately
after it detects a period of silence. When "unlimited" is selected, the machine does
nothing until the answering operation is completed (this also occurs when a period
of silence is detected). After the answering operation is completed, the machine
switches to receiving mode.
