Make the the following entries in Route table 3 in the Route table window:
(tab. for break out)
Line 1: Route 2, Dial rule 3, Warning: NONE
Make the the following entries in the Dialling rules table window:
Line 1: Rule name: Trunk, Rule format: A, Procedure: C&W single-stage (if main network supplier is
entered here instead of C&W single-stage, you cannot jump to lines in the route tables)
Line 2: Rule name: CorNet, Rule format: A, Procedure: Corporate network
Line 3: Rule name: Break out, Rule format: D77E3A, Procedure: Corporate network
Line 4: Rule name: Trunk via CorNet, Rule format: D77E2A, Procedure: Corporate network
Line 5: Rule name: To slave via trunk, Rule format: D02111234E2A, Procedure: Main network
supplier
(D02111234 is the Euro-ISDN route telephone number of the slave system)
Programming the slave system via Assistant E
Assign the protocol S0: CorNet-N variant 2 slave (direct) to the CorNet lines in the Lines/networking
window.
All other settings are programmed as described for master systems.
Closed numbering with break out in the master system via LCR
Prerequisites for programming example
The master system contains the extension numbers 100 - 499 while the slave system contains the
numbers 500 - 699.
Only the master system has an ISDN trunk connection with attendant code 0 (e.g. trunk group 1 with
code 0. A second trunk group code must also be assigned so that the slave system with trunk group
code 0 can seize a trunk in the master system. If this is not set, you will set up an attendant call in the
master system by dialling the digit 0 from the slave system!)
Both systems have a CorNet link to the remote system (route 2 in the master system, route 1 in the
slave system)
Programming the master system via Assistant E
Go to Routes in the Lines/networking window and select Route 2. Make the following settings:
Enter the route name, the trunk group code for route 2 must be deleted.
The route type is set to PABX in the Routing parameters window. The route telephone number
(PABX number) is set under No. and type, outgoing. A second route telephone number 77 is to be set
in addition to 0 for route 1.
The CorNet lines are to be assigned to route 2 in the Trunks window. Double-click on the asterisk in
the Param column for the relevant line to set the protocol to S0: CorNet-N variant 2 master (direct).
In the System Parameters window, ensure that the call number of the external attendant code is set to
