DEFINITY ProLogix Solutions Release 2 Overview 555-235-100 Issue 2 June 1999 10-4
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.)
