Routing Internal Calls
Internally the operator console is dialled up using the number of the switching cen-
tre defined in the numbering plan or via a call distribution element.
On an Aastra 5380/5380ip or Office 45 operator console the calls are provided on 
the line keys. If all the line keys are busy, the calls will be placed into the internal call 
queue.
On an Aastra 1560 / Office 1560, the calls are entered in the call queue for internal 
calls on the graphic interface. The operator select the call directly form the call 
queue.
Calls from the private leased-line network are handled in the same way as internal 
calls.
Routing a Personal Call (Internal or External)
The personal part of an operator console corresponds to an ordinary internal user. 
The calls are routed accordingly.
Call Signalling and Presentation on the Terminal
External and internal calls for the switching centre are signalled on all operator con-
soles.
Call Forwarding to a Substitution Destination 
Calls to operator consoles can be diverted to a substitution destination (see "Sub-
stitution Circuit", page 171).
In a two-company system the call forwarding destination applies to both compa-
nies.
