Data Rate
— 48kbit/s, 56 kbit/s, 64 kbit/s or external.
2.2.3.3 H.100 CT Bus
An H.100 CT Bus interface is provided to allow connection to other H.100 compatible
boards. The H.100 CT Bus supports 4096 channels (or timeslots) and the associated
clock and framing signals. This board is capable of generating the CT Bus clocks, or
can act as a slave. CT Bus channels may be used individually, or 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.
Bus type
— H.100 CT Bus
Clock rate
— 8192 kHz
Connector
— Edge connector
Clocking
— Master or Slave
2.2.4 Protocol Resource Support
When used in a signaling node, the DSI SPCI board supports the Message Transfer Part
(MTP) running on the board and optionally other protocols including MTP3, ISUP and
TUP. Board based protocols are enabled by a license button.
MTP3, ISUP, TUP, SCCP, TCAP, MAP, INAP and IS41 can also be run on the host. The
protocols are enabled by software licenses. See Section 2.3, “License Buttons” on page
12.
2.2.5 Visual Indicators
The DSI SPCI board includes the following visual indicators:
User LED’s : Three general purpose red LEDs, labeled A, B and C, are available to the
user application.
2.2.6 Power Requirements
Power requirements are described as follows:
• +5 VDC ± 5% power
2.0 A max., 1.5 A typ.
• Power dissipation
10.5 W max.
