•
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 CS 1000 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
