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 version

with 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 on

multistandard

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

p r o t o c o l s , a u t o m a t i c a l l y s e l e c t e d a t t h e c o n n e c t i o n ,

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).
