Feature transparency means that features work the same from a user’s perspective,
whether the telephones involved are assigned to the same switch or to different
switches. Users in a DCS can dial each other with four or five digits as if they were all
on the same switch.

Here are some examples of feature transparency in a Distributed Communication
System:
System:
•
Leave Word Calling (LWC) allows you to press a button on your voice-terminal
and leave a standard “call me” message with your name and phone number. When
your DEFINITY ONE is linked with other switches in a DCS, you can call any
employee in the DCS complex and press the LWC button to automatically leave a
standard message.

•
Calling-Party Name Display — If your telephone is equipped with a digital
display, information about the person calling you is displayed before you pick up
the receiver. With DCS, you can know who is calling whether that person is in a
nearby building or even across the country.

Centralized Messaging services for an entire DCS complex (subnetwork) may be
coordinated by one system, depending on the traffic volumes and versions of the
main and remote switches. This means that switches with smaller messaging
requirements do not share a voice messaging system with another switch.

DEFINITY ONE’s Distributed Communication System features DCS over ISDN-PRI
with path replacement for optimizing trunks. Thus when you transfer out of your
AUDIX voice messaging system, for example, DEFINITY ONE sets up a new path
that optimizes system resources.

Distributed Communications System and ISDN
Distributed Communication System nodes are connected by digital trunks (for
example, using DS1 or ISDN-Primary Rate Interface facilities). DEFINITY ONE can
send DCS messages over ISDN-Primary Rate Interface D channels. As a result, you
are not limited to private or leased facilities between your various locations. You can
also use public-network services. (See
example, using DS1 or ISDN-Primary Rate Interface facilities). DEFINITY ONE can
send DCS messages over ISDN-Primary Rate Interface D channels. As a result, you
are not limited to private or leased facilities between your various locations. You can
also use public-network services. (See
.)
The Software Defined Network supports every DCS transparency except the
following:
following:
•
DCS attendant control of trunk group access
•
DCS attendant direct trunk group selection
•
DCS busy verification of terminals
All other capabilities and limitations associated with the DCS still apply.
AUDIX systems networked via DCS can also be supported over ISDN-Primary Rate
Interface. (See
Interface. (See
