Basic Rate ISDN Line

When ordering your ISDN line from the telephone company, request EZ-ISDN 1 (Capability Package U) to ensure it is set up properly. EZ-ISDN 1 is recommended by the industry for most home office/small business applications. If EZ-ISDN is not available from your service provider order Generic Data M. For more information regarding ordering ISDN, see the ADTRAN document Ordering ISDN Service User Guide part number 60000.015-8, or contact the telephone company for alternative line configurations. The Ordering ISDN Service User Guide is available on the ADTRAN home page at http://www.adtran.com (under the Information Desk) or by calling ADTRAN.
