If you use a telephone line with tone dialling, the base station transmits signals
across the telephone line when you press the
R key. Telephone networks or
switchboards use either earth or hook flash as a signalling method. You will
find details of which one is used in the appropriate documentation. You must
set the base station to the appropriate signalling method for the telephone net-
work or switchboard.
Earth signalling
Earth signalling can only be used with a suitable telephone line.
To set the earth signalling method:
Route:
BaseStation » Settings » Basic » PhoneLine
1. Select
Basic
and press YES.
PIN:
is displayed.
2. Enter the PIN code for the base station (see page 78) and press
YES.
3. Select
PhoneLine
and press YES.
The opposite of the current setting is displayed.
4. Scroll to either
GoToEarth
or
GoToFlash
. If the display shows:
•
GoToFlash
press NO because the base station is already set to earth
signalling.
•
GoToEarth
press YES to set the base station to earth signalling.
Hook flash
Hook flash is a signalling method in a telephone network or on a switchboard
and is initiated by pressing the
R key on the handset. It is normally used for
call transfer. Hook flash actually simulates an on-hook-off-hook sequence
during a call. The length of such a sequence can be adjusted. In most cases the
factory setting (default) is correct. You will find details in the appropriate
documentation.
It is important to set the hook flash duration correctly. If it is set too short or
too long the telephone network or the switchboard may not detect a hook flash
or may even end the call.
The hook flash duration is limited to a certain range. If you try to exceed the
range, the handset sounds a warning tone and defaults to the lower or upper
limit.
