4. Order an ISDN Line
Call your local phone company and order an ISDN Basic Rate line.
To make ordering an ISDN line easier, Bellcore, in conjunction with the North American ISDN User’s Forum
(NIUF) and Local Exchange Carriers (LEC), have created several pre-defined ISDN packages which you can
order by simply specifying an ISDN ordering code (IOC).
Information to record when ordering your line
Ordering Code Features
EZ-ISDN 1 or
IOC: “U” Offers voice and data on both ISDN channels and supports advanced calling features such
as call conference, call transfer, and caller ID on the first ISDN number. You may have to
request these features individually, and there may be an additional charge for each one.
EZ-ISDN 1A or
IOC: “V” Same as EZ-ISDN 1, but adds Voice Mail support.
IOC: “S” Offers voice and data on both B-channels, but without any advanced calling features. If
you select this package, be sure to get Additional Call Offering (ACO). ACO is required
for call bumping (also known as dynamic bandwidth allocation) and call waiting to work
correctly. IOC “S1” includes ACO, however it is not supported everywhere.
EZ-ISDN 3 or 3A If you want to use Always On/Dynamic ISDN (AO/DI).
Capability Package AB Same as IOC U, but with advanced calling support on both channels and support for
AO/DI.
Capability Package AC Same as IOC V, but with advanced calling support on both channels and support for
AO/DI.
Item Description
ISDN phone number(s) The phone number assigned to your ISDN line. Some providers will give you two phone
numbers—one for each ISDN channel.
SPID(s) SPIDs (service profile IDs) identify the set of features and services provided by the ISDN
switch to which the ISDN device is connected.
When you subscribe to an ISDN line your provider allocates a SPID in the same way they
allocate an ISDN phone number. In some cases, the SPID is the same as the phone
number, in other cases it is the phone number with other digits added to it. It depends on
your provider.
Find out if your ISDN line supports AutoSPID. AutoSPID is a new National ISDN
protocol feature that enables the DIVA LAN ISDN Modem to automatically configure all
parameters for your ISDN line.
However, even if your ISDN line supports AutoSPID, it is a good idea to write down your
SPIDs.
Switch type The type of ISDN switch used by your provider. During configuration, the DIVA LAN
ISDN Modem automatically tries to detect the switch type your line is connected to.
However, if auto-detection fails, you need to manually specify the switch type. Three
types are supported: National ISDN-1, AT&T 5ESS, or AT&T 5ESSPP (5ESS
Point-to-Point).
Billing intervals Find out how your provider bills for ISDN usage. With this information on hand you can
configure the DIVA LAN ISDN Modem to minimize your connection costs. See
