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.
