Introduction
The Integrated Services Digital Network is being
developed
to
provide
telecommunication services over an all digital
network. The key element to this fully digital network
is to provide service integration using a global
a
full
range
of
standardized set of user access interface points.
These standardized interfaces are revealed in the
ISDN User Access Reference Model explained in
detail in Application Note MSAN-128, ”Implementing
an ISDN Architecture Using the ST-BUS”.
An essential element to the ISDN evolution is to
provide service to all end users while keeping the
cost affordable. To minimize the cost, ISDN must
utilize the existing network to its fullest and choose
the most economical set of digital interfaces. As
these
interfaces

The Subscriber Network Interface Circuit (SNIC) is a
four wire interface which terminates the on premise
subscriber loop. As such, it finds applications in
digital telephone sets, digital PABX line cards, low
rate multiplexer and in the NT1/NT2 functional block
of the ISDN reference model. This application note
deals with the functional details of the MT8930B/31B
as well as the network specification at the Subscriber
Network Interface. In order to take full advantage of
the contents of this note, reference must be made to
the MT8930B/31B data sheets.
