Telematics  
SNM46F, V34+ family  
SNM46F is a professional V34+ 33600/28800 modem/fax in  
standalone version, usually called “external modem”.  
It is projected and manufactured by digicom and its features are  
in conformity with the latest communication standards. The  
same product is also available in rackmount versionwith the  
name SNM46FR. The customer offering telematic services on  
switched network will be able to optimize the power connections  
and the modems management; the rackmount version, as well  
as the standalone one, can be managed by digicom’s  
Network Management called MSS01.  
The same design is proposed also in following versions:  
SNM41FPC for ISA Bus and CCM44F for PCMCIA Bus.  
Both products have the same characteristics of the standalone  
or rack version except for features in synchronous configuration  
which cannot be used in a personal computer.  
Thanks to Autosync standard it is possible to communicate in  
SDLC or X32 synchronous emulation towards systems of IBM  
midrange or mainframe family with emulators 5250 or 3270  
Autosync compatible; this software is quite popular and also  
IBM offers a version for 3270 environment in Dos or Windows  
and for 3270 and 5250 environment in OS/2.  
In order to offer a complete solution, digicom reached an  
agreement with MicroIntegration for the supply of Autosync  
compatible software in version 3270 for DOS and 5250 for DOS  
and/or Windows which can be used on PSTN with  
SDLC protocol or on PDN with X32 protocol.  
SNM46F and all rackmount, PC or PCMCIA models operate at  
a speed of 33.600/28.800 bps according to ITU-T V34+/V34  
standard and as they are based onmultistandard technology,  
they can connect to any modem down to the minimum speed  
of 300 bps (Pos applications...)  
Thanks to error correction with MNP4, MNP10EC and V42  
protocols, automatically selected at the connection,  
communications are guaranteed against any noise and  
transmission is allowed also through E-TACS cellular  
network for users working with portable PC and cellular  
phones.  
These modems have got a powerful compressor  
which is based on MNP5 and V42bis standards  
and allows to reach a speed of 115200 bit per  
second; it is possible to send 115200 characters per second  
and this means that a file of 200 Kbyte can be transmitted in  
a maximum time of 70 seconds and a minimum time of about  
20 seconds according to the number of errors, retransmissions  
and redundancy on the files.  
The whole family of SNM46F modems has got the fax feature  
which allows to transmit and receive faxes in conformity  
with group 3 recommendations (9600, 7200, 4800,  
2400 bps) but also at the highest fax speed  
14.400 bps (V17 recommendation). Complete  
software  
for  
fax  
management,  
communication to data banks and file  
transfer management is supplied free of charge  
and in Italian language with every digicom’s  
product.
