1-4 What does your AR100 need?
Ordering ISDN in Australia
The AR100 supports keeping an ISDN call connected semi-permanently. If you
subscribe to the OnRamp Express service in Australia, outgoing calls on this
line are charged at a lower rate than regular dial on demand ISDN calls. This
means that a call can be set up to remain connected indefinitely, and to be
reconnected if a fault in the ISDN network disconnects it.
Note: Only outgoing calls on the OnRamp Express service are charged at the
lower rate. Incoming calls are charged at the higher casual rate, even if the calls
are kept up semi-permanently, potentially leading to high ISDN call charges.
Ordering ISDN in North America
In the United States and Canada, Basic Rate ISDN is provided using National
ISDN-1, 5ESS or DMS-100 formats on the following switch types, all of which
are supported by the AR100 Series routers.
■
NI-1 (National ISDN-1)
■
5ESS (AT&T Custom, Point to Point or Multipoint)
■
DMS-100 (Northern Telecom)
Because an ISDN service provider uses hundreds of parameters to configure an
ISDN line, the North American ISDN Users’ Forum (NIUF) has defined some
standard Capability Packages to make it easier to order ISDN. Each capability
package consists of some standard line sets and feature sets that match the
requirements of particular applications. Many ISDN service providers have
implemented these capability packages, and you can order the one that suits
your needs by using the corresponding ISDN Ordering Codes (IOCs). The
ordering of ISDN services has been further simplified by defining some EZ-
ISDN packages which are supersets of Capability Packages that are expected to
meet the needs of many ISDN subscribers. Note that the EZ-ISDN packages 1
and 1A are the same as the superset capability packages U and V.
If your ISDN service provider does not use IOCs, see “ISDN Order Forms” on
page 1-7.
If your ISDN provider uses IOCs, use Table 1-1 to choose the capability pack-
age that suits your needs. Some ISDN service providers have lower call charges
for data-only applications. If this is the case and you do not require voice capa-
bilities, order an ISDN line that supports data only. Some ISDN service provid-
ers charge lower rates for voice calls than for data calls. The AR100 supports
Data Over Voice (DOV), enabling you to send data calls as though they are
voice calls, if the router at the other end of your calls is also configured for
DOV. Depending on your location and ISDN service, this may not be permit-
ted. If you will use DOV you may need to order an additional directory
number from your ISDN service provider. Voice features supported by the
AR140 are described in “Telephony on the AR140” on page 1-6.
You c an send th e ISDN Line Configuration Request Form with IOCs in
“ISDN Order Forms” on page 1-7, or call your telephone company and give the
corresponding information to the ISDN representative.
