In countries other than the USA, the router’s ISDN directory
numbers and subaddresses may be 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
AR Series Router Software
Reference
for more information.
Go to Step 5.

In the USA, the ISDN switch type and SPIDs values may also
need to be set. Setting the system territory to USA
automatically sets the ISDN switch type to National ISDN-1.
This should be correct for all new ISDN installations. If the
router is to be connected to another switch type, the switch
type can be set with the command:
SET Q931=0 PROFILE=DMS-100
for a Northern Telecom DMS-100 switch running custom
software, or:
SET Q931=0 PROFILE=5ESS
for a Lucent 5ESS switch running custom software.
If the switch type is not National ISDN-1, the SPIDs (supplied
by the ISDN service provider) must also be entered with
the command:
SET Q931=0 SPID1=
spid SPID2=spid
If the switch type is National ISDN-1 the router will, when first
turned on, attempt to obtain the SPIDs itself from the switch
using the Auto SPID procedures. The success of this procedure
can be monitored with the command:
SHOW Q931=0 SPID
If the Auto SPID procedure succeeds the router will either
select the SPID values to use by itself, or tell the user (in the
output of the SHOW Q931=0 SPID command) how to select
the SPID values.
If the Auto SPID procedures fail, SPIDs can be entered manually
with the command:
SET Q931=0 SPID1=
spid SPID2=spid
This section describes how to configure ISDN on the AR745
router using the command line interface. ISDN on the router
requires minimal user configuration, other than selecting a
territory, creating call definitions and configuring the Point-to-
Point Protocol (PPP) to use the ISDN calls. The lower layers of
the ISDN protocol stack (BRI, LAPD and Q.931) are
automatically configured when the router starts up.
Warning: The factory default hardware and software settings
described here are correct for European Union (EU)
countries. For other countries, contact your distributor or
reseller for details of local requirements.
CONFIGURING BASIC RATE ISDN
To configure Basic Rate ISDN on the AR745 router, follow
these steps:
1
Check the BRI hardware configuration. The AR745 router
can only operate in TE mode and is shipped with the standard
100
Ω
termination jumpers removed. This is appropriate for
most situations, where the building wiring provides the ISDN
termination. Your distributor or reseller can advise you whether
or not termination jumpers should be installed.
2
Select the country in which the router is being operated,
using 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 the
United States, use the command:
SET SYSTEM TERRITORY=USA
Warning: If you are not sure which territory to use, contact
your 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.
For installations in the USA, go to step 4. For installations in
other countries, go to step 3.
