FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Proprietary service -
Centralised Operator
Definition
In a stand-alone system all incoming external calls
which can not be answered, due to the fact that the
desired destination is busy, does not answer, is
blocked or not configured, will be routed to the
operator position.
This function also exists in a private network and is
called Centralised Operator (COP). All systems
covered by the private network are configured to
reroute an unsuccessful incoming external call to a
defined COP position.
The COP can be located in any proprietary PBX in the
private network, with the purpose to serve all network
users in the same way as users in the own dedicated
PBX.
Use
The aim of the Centralised Operator is to provide the
internal operator features to all users in the private
network, independent of whether the Centralised
Operator is located in the own PBX or in any other
proprietary PBX in the private network.
In a private network Centralised Operators are used
especially for these kind of configurations where you
have small systems included, which do not have a
dedicated operator of their own.
Operation
The Operator functionality in a private network is built
up via public ISDN (VPN: Virtual Private Network) and/
or via leased lines using QSIG with proprietary
signalling.
The following COP-features are supported:
• Bypass call forwarding
• Supervision of busy with recall at free
(similar to the Call Back on busy function)
• Camp on
• Intrusion with forced release
• Night Service Notification (only supported
when COP is located in ASB 501)
see also chapter ” Rerouting”
• Recall at No Answer
• State Presentation
• Transfer
For more information regarding Operator functionality
and especially on the difference between internal and
network behavior, see OPERATOR,
