## 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.
