Certain devices-most notably, some European fax
machines-only recognize a ring frequency of 25 Hertz
(Hz). Some telephones use a 20 Hz ring frequency.
Remote Gateway 9150 units connected to fax machines
that only recognize a 25 Hz ring frequency can require a
different Ring Frequency setting. To change this setting,
select 25 from this drop down list box.
Valid options are 20 and 25.
The default is 20.
Click on the up or down arrow to change the time zone
difference between this Remote Gateway 9150 unit and
the RLC.
Note: Time Offset is in 15-minute intervals to a maximum
of, plus or minus, 24 hours.
The default is 0.
