BusinessLink - General
The BusinessLink (CTI-link) integrates PBX
functionality with a computer environment. This can be
any single stand alone PC or Netware environment.
The link to the computer environment is based on a
V.24 interface using a proprietary protocol which fulfils
the functionality level of ECMA CSTA standard.
The user has the possibility to control the switch and
request services through the PC or workstation without
being physically connected to the switch. It allows the
PC client to initiate processes on behalf of any user/
agent in the system and therefore, save time and
increase productivity e.g. in call centre applications.
In other words the purpose of this interconnection is to
carry status information about devices (extension line,
trunk line, ACD group etc.) from the PBX to the
computer and requests for telephony functions from
the computer to the PBX.
BusinessPhone offers two different CTI-platforms:
• BusinessLink for Novell (BL Novell)
• BusinessLink for Windows NT (BL NT)
BusinessLink for Novell supports TSAPI for Novell's
NetWare. The BL Novell uses a serial V.24-interface
running with 9600 bps (19200 with R10 system
software) to transfer the information between the
exchange and the Telephony Server. The information
exchanged via this interface is a proprietary one.
The conversion from our proprietary protocoll to TSAPI
is done by a special NLM (Netware Loadable Module)
running on the Telephony Server.
The CTI-client uses TSAPI connectivity over Novell
Netware (3.x and 4.x) to communicate with the
Telephony Server and thus also with the exchange.
BusinessLink for Windows NT supports TSAPI on
Windows NT networks. The BL NT uses also a serial
V.24-interface running on 19200 bps to transfer the
information between the exchange and the Telephony
Server. The information exchanged via this interface is
a proprietary one.
The conversion from our proprietary signalling to
TSAPI is done by a special Windows NT Service
running on the Telephony Server (Windows NT
machine).
The CTI-client uses TSAPI connectivity (CSTA.dll)
over a Windows NT network (version 4.0 or higher) to
communicate with the Telephony Server and thus also
with the exchange. In the future, BL NT will also
support TAPI clients.
