on
page 56
for
information on the number of Legacy Link cards supported by an NBX
system.
■
The maximum loop length is 1000ft (300m).
■
The supported Norstar handsets are the M7000 Series and T-Series
models: M7100, M7208, M7310, M7208N, M7310N, M7324, T7100,
T7208, T7316, T7406 (digital cordless).

When connected to the card, the Norstar handset reflects the features
and functionality of the NBX Business Telephone. For details of specific
phone model features and capabilities, see the
Legacy Link for Norstar
Handset Compatibility and Overview.
■
The Norstar phones are line-powered from the card through an
external power source. No additional phone power is required.
■
The 3Com Legacy Link cards do not support compression. Voice traffic
between a legacy handset and an NBX device that supports
compression will be uncompressed.
■
Handsets connected to the card can be configured through the Button
Mappings page of the NBX NetSet utility. You can configure each
phone individually, but 3Com recommends that you use the
Telephone Groups option within the NBX NetSet utility to define a
group with specific button mappings for each telephone type, which
can then be re-used for any number of phones.
■
The Norstar Handset Overview document is available from the 3Com
web site. It compares the differences in operation of the Norstar
handsets, including button mapping and default layouts.
■
Quick reference cards are supplied with the 3Com Legacy Link for
Norstar card. You should replace the existing Norstar Quick Reference
Cards (situated under the handset on the Norstar phone) with the
new 3Com Quick Reference Cards provided.

Templates for Norstar Key Cap Labels and Norstar Phone Quick
Reference Cards can be obtained at
