874 NTAK091.5 Mb DTI/PRI card
The D-channel 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, and transmit clockoutput. The
receive and transmit clocks can be of slightly different bit rate from each
other as determined by the transmit and receive carrier clocks.
Feature selection through software configuration forthe D-channel includes:
•56 Kbps
•64 Kbps clear
•64 Kbps inverted (64 Kbps restricted)
DCHI can be enabled and disabled independent of the PRI card, as long as
the PRI card is inserted in its cabinet slot. The D-channeldata link cannot
be established however,unless the PRI loop is enabled.
On the NTAK09use switch 1, position 1 toselect either the D-channel
feature or the DPNSS feature, as follows:
OFF = D-channel
ON = DPNSS (U.K.)
