2.3 Hardware Overview
The SPCI2S and SPCI4 boards are full length PCI boards with 33MHz 32 bit
PCI interface. The boards are Universal expansion boards capable of detecting
the host signaling environment in use and adapting themselves to either +5V
or +3.3V signaling environments.
Note: The distinction is the signaling protocol used and not the power rail to which board
connects.
Each board has an H.100 CT Bus interface, which is used to provide
connectivity to further boards or to other H.100 CT Bus compatible boards,
such as voice processing and fax cards.
The H.100 CT Bus supports 4096 channels (or timeslots) and the associated
clock and framing signals. Each board is capable of generating the CT Bus
clocks, or can act as a slave. CT Bus channels may be used individually or can
be grouped to provide a higher bandwidth data path. The signals are carried
between boards in a host computer using an H.100 CT Bus ribbon cable.
2.4 System Requirements
To use the SPCI2S or SPCI4 signaling board, the host computer must meet
the following minimum specifications:
• This signaling board is for use only with UL listed computers that have
installation instructions detailing user installation of card cage
accessories.
• Rev. 2.1 PCI compliant computer system.
• One free 33MHz 32 bit PCI full size expansion slot.
