Slip control
Slip control provides organized recovery of PCM when the clock recovered from the external
facility is at a different frequency with respect to the local clock.
D-channel support interface
The D-channel support interface is a 64 Kbps, full-duplex serial bit stream configured as a DCE
device. The data signals include:
• receive data output
• transmit data input
• receive clock output
• transmit clock output
The receive and transmit clocks can be of slightly different bit rates from each other as
determined by the transmit and receive carrier clocks.
The NTBK50 supports a D-Channel Handler Interface (DCHI) daughterboard. It is equivalent
to a single port of an NTAK02 SDI/DCH card. The NTBK50 also supports a Downloadable D-
Channel Handler interface (DDCH) daughterboard. The DDCH brings MSDL D-channel
capability to the system.
DCHI Configuration for NTAK93 only (SW1)
The NTAK93 DCHI daughterboard can be operated in two separate modes 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 DPNSS mode, which is not supported at this time. The DDCH
supports only a single port which directly interfaces to the PRI motherboard. See
Settings for the DCHI dip switch (SW1)
on page 558.

Card-LAN interface
A Dual Port UART handles the functions of the serial ports for the Card-LAN serial link test
port interface. The test interface is an asynchronous 4800 bps 8 bit connected to port A of the
NTBK50 2.0 Mb PRI card
