Mitel 3000 Australia Installation and Maintenance Manual
The data port is primarily intended for PC modems rather than standard
telephones. Caller ID information is supplied to Feature Phones as a
digital signal on the c-d pair. This means that the Caller ID information is
not supplied on the a-b pair, so it is not available to any device
connected to the data port on the Feature Phones.
The Caller ID information for internal and external calls is supplied to the
phone. The 0 is inserted when the number is received from an external
call. The 0 is not stored when the call is received from an internal call.
Using the 0 allows both internal and external calls to be redialed from
within the phone's Caller ID store.
The data port provides the location for the connection of devices such
as PC modems, cordless telephones, additional ringers/ringer lights or
recording equipment (recording equipment needs to be ac coupled). It
is important not to go off hook on a cordless telephone or modem when
on a call on the feature phone as you will hear 'dead air' on the feature
phone, which might be mistaken for a loss of transmission. Equally, do
not try to operate the feature phone when the data port (analog phone
or modem) is off-hook. If you are swapping between a Feature Phone
and cordless telephone you should go off hook on the cordless
telephone before hanging up on the Feature Phone if you want to
maintain the call in progress.
Note: If your modem is configured in auto-answer mode (for example
because the connected PC is running a fax or answering machine
application), then incoming calls may be answered unexpectedly by the
modem.
As Designed. This shows that handsfree intercom answer is enabled.
The phone programming settings are not updated when a database is
restored.
This includes:-
- Auto Answer
- Headset mode
- Background music
- Ringing Options
- Contrast Options
The Time and date is not restored. This needs to be set separately
when a database is restored as the recovered time will not be correct by
the time it is resent.
This is usually caused when the caller has hung up and the phone(s)
continue to ring for a period. If the ringing phones are answered during
this period it will appear to be a "Phantom call" - no one is on the line.
The ringing signal on the PSTN line is ringing on for 1 second, off for 4
seconds, repeated. When a caller hangs up the line stops sending the
ringing signal. However the system will not be aware that the ringing
has stopped for some seconds. The system will stop ringing the internal
extensions when it has not detected a ringing signal on the line for a
period 5.5 seconds. The internal phones will still indicate there is a call
