The NTAK93DCHI daughterboard can be operated in two separate modes
as defined by an on-board dip switch. It can operate in a standard DCHI
mode common to most ISDN standard countries. It can also operate in a
U.K. specific mode using the DPNSS format. The DDCH supports only a
single port which directly interfaces to the PRI motherboard.

Card-LAN interface
A Dual Port UARThandles the functionsof the serial ports forthe Card-LAN
serial link test port interface. The test interface is an asynchronous 4800
bps 8 bit connected to port A of the UART.The card-LAN interface is an
asynchronous 19.2 kbps 9 bit start/stop connected to port B of the UART.
The connection to the test port is available at the backplane/MDFconnector.
