Signaling interface

The 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

For the E1 interface, the connection to the external digital carrier is provided by the line interface chip. This device 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.
