ISDN Ordering Codes (IOCs)

ORDERING ISDN USING IOCS

The development of ISDN ordering codes (IOCs) simplifies the process of or-

dering ISDN service. The ISDN Solutions Group, a consortium of ISDN equip-

ment vendors, service providers, and Bellcore, established these codes to

represent predetermined line configurations for ISDN Basic Rate service for

specific applications.

ADTRAN and Bellcore have registered and tested eight generic IOCs. Of

these, four are recommended for operation of the ISU 128. After reviewing

the following list, order ISDN lines from the local service provider. Request

the appropriate IOC for your application. They are described in detail in this

chapter.

In some areas, ISDN tariffs may warrant the use of ordering codes with less

features. For example, in a particular region, there may be additional monthly

expense associated with having voice service on each B channel. If you have a

data only application,

Capability R

(previously

Generic Data I

) may be more

cost-effective.

If these are not available from your service provider or you would like more

information regarding ordering ISDN see the ADTRAN document
