FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Proprietary service - Call Transfer
Definition
The existing “Call Transfer” (for detailed information regarding the function, see Facility Description TRANSFER,
document 485/155 34-ASB 150 02 Uen) has been modified to display the correct Calling/Connected Line/Name
Indentity of the involved CN parties.
Operation
Since signalling during the alerting and active phase is required (sending of new number and name), UUS services 2
and 3 must be activated so that the proprietary CN Call Transfer can work with a full display support .
If one involved party cannot use UUS (e.g.: a user from the public ISDN), the Call Transfer is nevertheless carried out
but this party is not provided with the new private number or name. That means it is possible to transfer all internal
and external calls (private or public), but only external users in the private network who can use UUS 2 and/or UUS 3
are provided with the new private number and name by using the proprietary UUS protocol.
Example1
Both connections before Call Transfer (A <-> B and C <-> B) are Regional calls (TON of Calling/Connected numbers
= RL1). The new connected numbers, which are sent from the transferring exchange to the new originating and the
new terminating exchange after CT, have the correct prefix for display presentation at the new originator / terminator.
