1. 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.

Untilrecently only thelarge InternetService Providershavebeen ableto offer56Kconnectivity

totheir subscribers. Now Digicom,Italy’smajor modemmanufacturer,providesthisinnovative

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.

Onhandshaking the SNM70determines themaximumspeed of56K andareliable 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.

3. DUAL MODEM SETUP

The SNM70 has dual, fully featured, digital K56flex modems inside one box: infact on the rear

pannel you can see the RS232 serial interface connector of modem 1 (orA) indicated as JC

and the RS232 serial interface connector of modem 2 (or B) indicated as JA.

For the above reason, the user must setup of the two modems separatly. We suggest startingt

the setup with the modem 1 connector JC and then proceed with the modem 2 connector JA.

The following AT command description is valid for each modem.

3.1. MODEM AT COMMAND SET

The modems support the AT command set, to define the configuration, initiate or terminate

modem communication, and to test the modem and the communication link. The modem will

work in two basic modes: command mode and data mode.

Command mode is when the modem is not connected to another modem, therefore “Off Line”

or in a idle condition. In this mode the modem will accept commands beginning withATprefix.

Data mode is when the modem is connected to another modem, that is an “On Line” condition

or functioning. In this mode all the characters sent from computer are interpreted as data and

they are sent to the remote modem. You may switch from data to command mode by entering

anescapesequence.Thedefault escapesequenceis +++this must haveat least onesecond

before and after being keyed. To go back into data mode simply typeATO.

Data Length

Each caracter of the AT command must be an ASCII code with any of the following format

combinations:

START BIT DATA BIT PARITY STOP BIT TOTAL

171110

180110

170210

171110

The modem will accept even, Odd, mark, or space.

3.1.1. AT COMMAND SET DESCRIPTION

AT Attention

All the characters following the letters ‘AT’ are commands. InAT command mode the modem

automatically detects the computer speed and parity format. The modem will response using

the same speed and parity format ofAT command.
