Parking (replugging on the bus) in the ISDN ex-
change
You can temporarily interrupt an external call and
park it in the ISDN exchange because for example
- you want to continue the conversation from an-
other ISDN telephone at the multi-equipment
access (bus)
- you have answered a call on the ISDN
telephone at the multi-equipment access and
want to continue it on an analog telephone of
the telecommunications system.
The line (B-channel) becomes free when the call
is parked in the exchange.
You have to continue a parked call within 3 min-
utes. The ISDN exchange disconnects the parked
call after 3 minutes.
Since several calls may be parked at your ISDN
access, you have to identify every parked call with
a "connection ID".
Please see the appropriate operating instructions
to find out how to park and unpark a call with an
ISDN telephone.

Every internal subscriber can pick up (unpark) the
external call. If two external calls are parked in
the telephone system, the first external call is
given priority for unparking.
If the parked external call is not recovered within
4 minutes, you will receive a recall.
The parked external call causes connection costs.
