10 Distributed Communication System

To support DCS customers, DEFINITY ProLogix Solutions can transport DCS messages over ISDN- Primary Rate Interface D channels. As a result, you are not limited to private-line connections between your various locations. You can also use the Software Defined Network (SDN) services.

The Software Defined Network supports all DCS features except the 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 Chapter 4 for more information.)
