2.2.2 Host Interface
The DSI SPCI board is a 32-bit PCI board, but can also be installed in 64-bit PCI slots.
The board is keyed as universal and can be installed in either 5 V or 3.3 V signaling
environment slots.
2.2.3 Physical Interfaces
The DSI SPCI board supports the following physical interfaces:
• DSI SPCI4 - Four T1/E1 digital trunk interfaces. See Section 2.3.1, “Run Modes”
below for more detail.
DSI SPCI2S – Two T1/E1 digital trunk interfaces.
