GENERALITY
This operating manual describes the installation
procedures and the main features of the
SNM 70, the innovative K56Flex™ host modem.
DEAR CUSTOMER,
Thank you for choosing a Digicom modem.
Until recently only the large Internet Service Providers have been able to offer 56K connectivity
to their subscribers. Now Digicom, Italy's major modem manufacturer, provides this innovative
and unique 56K host modem that will enable any business to benefit from the near ISDN
connecting speeds for remote access to LANs, BBSs or PC's.
The SNM70 K56Flex host modem is a direct replacement for the slower 33.6 V34bis modem.
At the host site (or remote LAN access node) the SNM-70 connects to the telephone network via a
single ISDN Basic rate Interface (BRI). The SNM-70 has 2 RS232 communication ports for interface
to the host equipment and can accept 2 simultaneous incoming connections at 56K.
To realise the 56K connection speed the remote user (client) must have a K56Flex standard
modem and simply dials one of the two telephone numbers to connect to the host modem.
On handshaking the SNM70 determines the maximum speed of 56K and a reliable connection
is established. If the incoming call is from a slower 33.6 V34 modem then connection is made
at 28.8/33.6 Kbps, or the fastest speed supported by the remote user modem.
