Signaling interface
The signaling interface consists of the A07 DS-30X signaling controller. This interface provides
an 8 Kbps signaling link through the DS-30X timeslot zero data bit zero. Messages are 3 bytes
in length.
Carrier interface
The E1 interface connection to the external digital carrier is provided by the line interface chip.
This chip provides accurate pulse shaping to meet the CCITT pulse mask requirements. It
provides clock recovery functions on the receive side as well as tolerance to jitter and wander
in the received bit stream.
Impedance matching
The line interface provides for the use of 120 ohms twisted pair cable. The impedance is
selected by a switch, as shown in
Table 232: Impedance matching switch selection
page 528.

Note:
The ON position for all the switches is towards the bottom of the card. This is indicated by
a white dot printed on the board next to the bottom left corner of each individual switch.
Carrier grounding
The NTAK79 card provides the capability of selectively grounding the shield of the Tx and/or
Rx pairs of the carrier. Closing (down) the on-board switch applies FGND to the appropriate
NTAK79 2.0 Mb PRI card
