Digicom Network Card SNT09 User Manual

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.
