4.2.4 Inhouse calling
You would like to make an inhouse connection with another PABX subscriber.
b
Lift up the receiver of your phone.
You will hear the internal dial tone.
t
Dial the number of the inhouse subscriber you wish to call.
You then hear the ringing tone. The inhouse subscriber is being
called.
The called subscriber answers his/her phone.
g
Conduct your call.
a
Hang up the receiver of your phone to end the inhouse call, or
the inhouse party you are taking to hangs up the receiver. You
then hear the busy signal. Hang up your receiver. This cancels
the inhouse connection.
4.2.5 External connections
You can establish two external connection simultaneously via the two B
channels of an ISDN connection. These connections can also exist simultane-
ously with two different parties.
This allows you, for example, to call an external business partner while you
simultaneously transmit data from your PC to another business partner.
An external caller who has dialed a non-existing internal direct dial-in number
when the PABX is set up for a point-to-point connection, is signaled at the
telephones in the switchable call modes. At the same time, the central alarm
bell can be activated.
When you make an external call via your PABX, the PABX automatically
transmits the service identification character that has been programmed for the
analog connection or in the ISDN terminal.
Please note: ISDN terminals linked to multipoint connection and the internal
ISDN bus may not always have the same dial tones, calling cycles and operating
procedures as the PABX analog terminals. This has nothing to do with your
PABX, but results because of the differing ISDN terminals.
