COMMON BELL
Definition
Common bell facility gives to all extensions the
possibility to pick up the call from an extension that has
been predefined as a common bell extension.
If the common bell feature is used in large working
areas, it may be a good thing to use a mounted bell in
connection with the common bell extension in order to
attract everybody’s attention.
Use
Common bell is similar to the function of the call pick
up group, however the difference is that all extensions
can pick up the common bell call.
The common bell extension used in small working
areas can be that of the operator.
In the systems that already have an operator, the
common bell extension can be the answer position of
the off-duty operator.
Common bell extension can be programmed as a night
answering position too.
Operation
All telephones
If a call is waiting at the common bell extension, all
extensions of the system (operator included) can pick
up this call by dialling a programmable common bell
pick up code:
• Lift the handset (ANALOGUE or BASIC tele-
phones)
• Dial the relevant common bell pick up code (de-
fault value *73#).
• The connection between the extensions will be
established immediately and at the same time
the common bell extension will be ready to treat
the next call.
If two or more extensions try at the same time to pick
up a call from the common bell extension, just the first
one will pick it up. The other extensions will receive the
"number unobtainable" tone. In addition to this tone,
the extensions with display will show:
EXECTUTIVE telephone
STANDARD telephone
The same situation will be faced if you dial the
common bell pick up code and no calls are present at
the common bell extension.
Capacity
One extension of the system can be defined as a
common bell extension.
Limitations
An operator must not be defined as a common bell
extension.
The code of the common bell, naturally must be
different from those of the pick up groups.
The extensions that have no access to the common
bell extension (prohibited by traffic group), can not pick
up the common bell calls.
