Installing the SCbus Interface Board

in the Impact FXS Digital Communications System

Introducing the SCbus Interface Board

The SCbus interface board allows Computer Telephony (CT) applications to connect one or more SCbus

compatible circuit boards in the Impact FXS computer (for example; network, voice, facsimile, speech

recognition, video, and so forth) to the Impact FXS’ digital station or trunk ports through time division

multiplexing (TDM) on the SCbus.

SCbus is a TDM bus for communications within a node of the Signal Computing System Architecture (SCSA).

(The SCSA standard specifies the signal processing system for PC-based voice and call processing, and telecom

switching.) The SCbus features an architecture that includes a serial message path for signaling and control and a

16-wire parallel Time Division Multiplexing (TDM) data path.

The conversion of a CTI application from traditional loop start ports to digital SCbus ports provides a more

effective and efficient operation than that provided by analog ports, which historically have been used in the CTI

industry.

CTI applications use the Enterprise or wideopen.office

toolkit in order to perform switching operations and call

processing on the Impact FXS SCbus interface board that is plugged into the Impact FXS proprietary telecom

backplane. These toolkits consist of PC software libraries that provide the instructions to the FX system for

performing these functions.

When installing more than one SCbus interface board, install the first one in the 6th (top) universal board slot of

the Impact FXS telephony portion and the next one in the 5th universal board slot, and so forth. Connect the

SCbus interface board’s ribbon cable to the CTI application board that is plugged onto the Impact FXS

computer’s motherboard. The internal cable connection between the SCbus board and the CTI application board

routes the voice-path between the two locations. Attach the PC power cable from the power supply to the SCbus

interface board to the first SCbus interface board you installed. Any subsequent SCbus interface boards you install

do not require the power connection. In addition to these internal cables, the installation requires external cabling

between the Impact FXS system’s computer and telephony portion. The particular external cabling required is

dependent upon the CTI application being operated. For example, when using a voice mail application, a cable is

required to connect the computer’s COM 2 port to the telephony’s COM 2 port. The cabling requirements are

illustrated in the figure on page 7 of this instruction.

An SCbus installation includes the following items:

•

SCbus Interface Board (product code FXSCBUS),

•

SCbus Application Board or Boards (as needed),

•

Enterprise ToolKit Software including all required disks (product code ENTRP-SW).
