DIVA T/A ISDN Modem User’s Guide 8
Using EZ-ISDN or ISDN Ordering
Code (IOC) to order your ISDN
Line
(North America only)
We highly recommend that you use our toll free ISDN ordering
service to make sure you get the correct ISDN line the first time. This
service is free to our customers. Dial 1-888-800-DIVA.
EZ-ISDN / IOC simplifies the ordering of your ISDN line. It lets you
use simple codes to order pre-configured packages of ISDN features
and services.
The North American ISDN User’s Forum (NIUF) and Local
Exchange Carriers (LEC) administer the assignment of codes.
Bellcore administers the National ISDN Ordering Code (IOC)
process.
We recommend the use of the following ISDN Ordering codes:
•
IOC “S” offers basic voice/data features without the advanced
calling features described below. If you select this option, make
sure to get Additional Call (ACO). ACO is required for Call
Bumping (also known as Dynamic Bandwidth Allocation--
DBA) and Call Waiting to work correctly. IOC “S1” includes
ACO, however it is not supported everywhere.
•
EZ-ISDN 1 (or IOC: “U”) adds voice/data to both B-channels.
The Advanced calling features such as Call Conference, Call
transfer, etc., are only available on one B-channel.
Note: Calling Features only apply to DIVA T/A models
equipped with analog ports. For more information on Calling
Features, see page 100. For more information on analog device
support, see page 98.
•
EZ-ISDN 1A (or IOC: “V”) adds VoiceMail to EZ-ISDN.
•
EZ-ISDN 3 or 3A adds Always On/Dynamic ISDN (AO/DI)
support.
Note: If you want to use the DIVA T/A’s Calling Features, ask your
ISDN service provider for the values of the Feature Keys. You need
these values to ensure that the DIVA T/A has full access to these
features. Refer to the section “Feature Key Values” on page 102 for
more information.
