2. Select the territory.
To select the country or region in which the router is operated, enter the
command:
SET SYSTEM TERRITORY={AUSTRALIA|CHINA|
EUROPE|JAPAN|KOREA|NEWZEALAND|USA}
The territory determines which Q.931 profile is used on the ISDN interface.
For example, to select the Q.931 profile for New Zealand, enter the
command:
SET SYSTEM TERRITORY=NEWZEALAND
If you are not sure which territory to use, contact your authorised distributor
or reseller. Failure to select the correct territory will invalidate the approval of
this product with respect to the applicable national standards for the country
in which the product is used.
3. Set directory numbers and subaddresses.
The router’s ISDN directory numbers and subaddresses are set with the
command:
SET Q931=0 NUM1=number NUM2=number SUB1=subaddress
SUB2=subaddress
This step is only required if the router is sharing the ISDN S/T bus with
other ISDN devices. See the Software Reference for more information.
4. Create call definitions.
Create ISDN call definitions to enable the router to make ISDN calls to
other devices on the ISDN network. This is the only step you must
complete to configure ISDN on the router. Before a call can be made from
one router to another, create call definitions on both routers, by entering
the command:
ADD ISDN CALL=name NUMBER=number PRECEDENCE={IN|OUT}
options...
For example, a Remote Office router is to be connected to the Head Office
router via ISDN. The ISDN number of the Remote Office router is 1234567.
The ISDN number of the Head Office router is 9876543. The called party
subaddress information element (IE) is used to carry connection
information, and PPP interfaces are created explicitly to use the ISDN calls.
Either router can initiate the call, but calls from the Remote Office have
precedence. On the Head Office router, to create a call to the Remote Office
router, enter the command:
ADD ISDN CALL=ROHO OUTSUB=LOCAL SEARCHSUB=LOCAL
NUMBER=1234567 PREC=IN
On the Remote Office router, to create a call to the Head Office router, enter
the command:
ADD ISDN CALL=ROHO OUTSUB=LOCAL SEARCHSUB=LOCAL
NUMBER=9876543 PREC=OUT
Each call has the same name (ROHO), and this name is passed via the
called subaddress IE to provide identification to the remote end of the link.
Each router will search for this call using the called subaddress IE.
You must set the precedence to ensure that in the event of a call collision
(the same call made and answered at the same time), one call is completed
and other call is cleared. The direction of precedence is not important, but
