The H.110 Basic Rate ISDN Board
The Infinity Series H.110 Basic Rate ISDN Board actually consists of two
boards. The front board which contains the processor, DSP’s, switching,
HDLC controllers, and logic. The rear board contains the interface and
connectors to the Basic Rate Interface ports.
3.1 PCI Configuration
As Infinity Series boards conform to the PCI standards, there are no
switches to set to configure the H.110 BRI Board's memory address, I/O
addresses, or interrupt. The host processor’s bios will automatically
configure the board at boot time to avoid conflicts with other boards in the
system.
3.2 Jumpers & Headers for the Front Board
The following is a complete list of all jumpers for the H.110 BRI ISDN

downloaded firmware will be executed after a reset if it is

default firmware is executed after reset.
