If You Place Your ISDN

telephone company and schedule installation of your ISDN line wherever possible.
Be sure to ask for the order code or order confirmation number.
If You Place Your ISDN
Order Through the
Telephone Company
To simplify the many features available for ISDN, Bellcore has created several
packages, called ISDN Ordering Codes (IOC), for choosing an ISDN line
configuration that best fits your needs. Of these packages, 3Com has two
recommendations, each of which allows you to take the fullest advantage of the
supplementary voice features supported by the ISDN LAN Modem. The ISDN LAN
Modem has completed the ISDN Ordering Codes Translations Review and is
registered with EZ-ISDN 1 and EZ-ISDN 1A.
Your choice will depend on whether or not you want Voice Mail capability on your
line:
■ For ISDN without Voice Mail, 3Com recommends
Capability Package U or
EZ-ISDN 1.
■ For ISDN with Voice Mail, 3Com recommends
Capability Package V or
EZ-ISDN 1A.
For a complete explanation of these Capability Packages, the specific
supplementary services included with each, and certain limitations in their
coverage which relate to the ISDN LAN Modem, refer to the two sections,
“Supplementary Voice Features Included with U, EZ-ISDN-1, V and EZ-ISDN 1A”
and “Limitations of ISDN Ordering Codes U, EZ-ISDN 1, V and EZ-ISDN 1A.”
