BusinessLink for Windows NT
Version1.1
Definition
The BusinessLink for Windows NT (BL NT) provides
an external computing device with control functionality
to request telephony services from the PBX and
response reports events on every activity within the
CTI environment. BL NT is based on proprietary
signalling via a serial V.24 interface between the PBX
and the CTI Server. The clients (e.g. ACD-agents,
Operators) are connected to the CTI Server by means
of a Local Area Network (LAN) which is based on a
Windows NT. The software on the client side is a DLL
(Dynamic Link Library) which translates the messages
from the Teleophony Server towards the client
application. The (digital) CSTA telephone devices of
the clients are connected directly to the PBX. The
propiretary information from the PBX is converted to
TSAPI standard with a Windows NT intermediate
Service in the CTI Server.
Use
With the BL NT it is possible to run TSAPI applications
in a Windows NT network. The big advantage
compared to BusinessLink for Novell is that there is no
need for additional software to provide CTI
functionality towards client PCs.
Two different client software modules are part of the
BL NT product:
• 32-bit CSTA.dll
The 32 bit CSTA.dll is the standard interface for
applications to the Windows NT environment. It is used
by the BusinessPhone Call Centre Assistant (CCA)
and the BusinessPhone Operator Suite (OWS) and all
other 32 bit applications to communicate with the CTI
Server and the PBX.
• 16-bit CSTA.dll
The 16 bit CSTA.dll is required to run 16 bit CTI
applications on Windows 95 or Windows NT client
PCs.
Note: The 16 bit CSTA.dll is not yet released.
Operation
Due to the fact that BL NT use the same CTI interface
than BL Novell, the main functionality of the BL NT
remains the same. Therefore, in this document only
new features compared to BL Novell are explained.
• Monitoring of ACD groups
New calls to an ACD group are presented directly to a
free ACD agent or are queued before they are handled
by one of the ACD agents belonging to this group. In
order to provide the CTI Server with event and status
information about the calls which are handled by the
ACD group, it will be possible to start a CTI monitor on
an ACD group. After the successful start of a CTI
monitor on the directory number of an ACD group the
following information is forwarded to the CTI Server:
• Calls alerting at the ACD group,
containing the connected party number.
