1.1.1 The Physical Interface
Thirty-two independent ports are provided on the board. Each port on the
board provides a complete S/T Basic Rate ISDN interface. This interface
can be configured under software control as either a piece of terminal
equipment to interface to a central office or PBX, or as a network
termination to interface to terminal equipment such as ISDN phone sets or
ISDN modems. Layer 1 support is provided by the board to handle all the
details of framing and clocking.
