Your
MERLIN
Communications System was designed to provide you
with sophisticated telephone service. Modular and expandable, it can
grow as your business needs grow. You can increase the usefulness of
your
MERLIN
system by installing a Type I Feature Cartridge in your
Control Unit. If you have such a Feature Cartridge, ignore this document
and read the material that came with the cartridge. If you’ve elected to
stay with Standard Features for now, this Guide will tell you how they work.
This guide explains Standard Features for three different models—the
206, 410 and 820. They differ in the number of lines and voice terminals
(telephones) that can be accommodated.
You can use a variety of different voice terminals with your
MERLIN
system. All
MERLIN
voice terminals, available now or offered in the
future, will work on your
MERLIN
system. The same is true of almost
all accessories.
