Data Communication
SNT09
One of the possible applications on ISDN network is the back
up and restore of the leased connections. This function is
particularly required in EDP environments where the reliability
of leased lines is necessary.
SNT09 has been projected and manufactured to face these
requests. It is a very sophisticated equipment able to route
automatically the data transmitted on digital and analog direct
circuits, over ISDN switched connection.
When SNT09 is connected to DCEPlus on the CDN national
line,it is able to interpret the ACDdata which are also indicated
on the MSS01 consolle. This can be used for the network
device management and for the back up and restore accounting.
SNT09 enables and disables the alternative circuit both on
Point to Point and on Multipointconnections on the basis of
sophisticated criteria like line presence or absence,
error percentage on received and transmitted data, coming
from a statistical analysis on the main link activity.

The routing on an alternative connection takes place without
interrupting the data transmission, therefore each terminal
connected to SNT09 can “see” the geographic
connection in a transparent way.
SNT09 is equipped with a clock/calendar in order
to programme possible stop, to change the time
with one command only.
SNT09 is a made in Italy product which
is projected and manufactured by digicom S.p.A.,
leading company on the market for twenty years
with Quality Certification according to
ISO9001/EN29000andBABT.
The product is homologated, marked and it is in
conformity with ITU-T recommendations
warranting thehighest Quality Level.
