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 outdoor 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 during the wait
During the wait, the microphone is obviously muted and will remain as such also when the switchboard operator connects
the internal unit to the other party, which means that, once connected, it will be necessary to use T3
to re-enable
the microphone. Alternatively, you can also use T3 before the new connection is made. In this case the microphone
will already be enabled. Given that it is not possible to know beforehand the exact moment at which the switchboard
operator will connect the internal unit to the other party, this strategy has been chosen in order to ensure that the other
party hears nothing unless at the explicit request of the party waiting.
