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.
The Meridian 1 signaling interface consists of the A07 DS-30X signaling
controller. This interface provides an 8 Kbps signaling link via 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.
