DCS Compact II General Description
Each Miscellaneous card provides a dry contact pair to control a customer–
provided common bell or common audible device. These contacts must be
programmed as members of a station group and may provide steady or
interrupted closure.
Computer Telephony Integration (CTI)
Computer Telephony Integration (CTI) allows integration between the DCS
Compact II and a personal computer system (PC) or a local area network (LAN).
Caller ID service is required on TAPI and TSAPI inbound call applications that
use the CLIP information to display computer records in conjunction with the
presentation of the call to the station on the DCS Compact II system. TAPI and
TSAPI are described below.

l TSAPI (developing)
Jointly developed by Intel and Microsoft, TAPI(Telephony Applications
Programming Interface) Delivers telephony features to the Windows
desktop. TAPI is an open application interface (OAI) protocol that supports
First Party Call Control. A DCS Compact II Computer Telephony Module
(CTM) is required to connect any keyset to a personal computer running
Windows 3.1 or Windows 95. The number of CTMs that can be installed
on a system is only limited to the number of keyphones. The features and
functionally of the DCS Compact II keyset are not changed.
TSAPI (Telephony Services Application Programming Interface) was
developed by Novell and AT&T and is the method of integrating the DCS
Compact II system to a computer. TSAPI is a LAN based solution allowing
computers to communicate directly to the telephone system over the
network system. This establishes a logical connection rather than a
physical connection between telephone and computer. It eliminates the
cost and administrative overhead of connecting every PC to a desktop
phone. It emphasizes third–party call control. (Example: calls can be
tracked as they are transferred, making it more suited to large office
applications). TSAPI can emulate first–party type call control for the DCS
Compact II system, rather than from the telephone as TAPI does. For
example, to make a call the DCS Compact II rather than the telephone
would dial the phone number, and the call would be then transferred to
the telephone. Novell Telephony Services 2.1 or higher specifies the data
communications link between the Novell Netware file server running the
Netware Telephony Services NLM and the Samsung DCS Compact II. The
