Switchboard scenarios
If the unit either making or receiving the call is a porter switchboard, there are other possible scenarios. For
example, the switchboard operator could connect an internal unit to another internal unit, to an external unit or
to a second porter switchboard.
If the switchboard operator already has the other internal unit, external unit or switchboard on hold, he/she will
connect it directly.
Alternatively, he/she could put this internal unit on hold while carrying out the necessary operations to call the
other party. The switchboard operator can only connect an external unit to the internal unit if the external unit
is already on hold:
Internal unit connected to external unit
During the wait, the internal unit will emit a specic tone. The internal unit can also cancel the wait by putting
the internal unit in standby mode using the P/A key.
Internal unit put on hold
During the wait, the microphone is obviously muted and will remain as such also when the switchboard operator
connects the the internal unit to the other party, which means that, once connected, it will be necessary to use
