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
