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 Ordering ISDN Service User Guide part number 60000.015-8 or contact your telephone company for alternative line configurations. The Ordering ISDN Service User Guide is available on the ADTRAN home page at http://www.adtran.com or by calling ADTRAN.
