USERT is the remote identity.
Neither telephone number nor dialback function exist.
The access level is 0.
K=01-02 If USER1
should login, this field instructs the modem to
use key index 1 or 2.
Key number 0 is only used during the key negotiation and is not
used as a definite key.
In encryption mode, the answering
modem determines which of the keys to be used.
If it is possible
to choose among several keys, as in the example above, the
answering modem will choose one of them at random. The call
modem must have all the possible keys stored in its key table.
The key negotiation is further described in the section
«Key negotiation diagram».
Seen from the users point of view the modem is operated as
normal whether a connection is made in DES mode or not. From
the originator site (your modem is already configured):
Dialling
ATDT3701
1710 ge
The modem dials number 37011710
and connects.
Result code: CONNECT 14400
As soon as a successful DES connection is made, the modem
behaves just like having a normal V.42 bis connection. (Error
free channel with data compression).
Asynchronous or synchronous/general requirements.
in synchronous communication with encryption an extra
hardware module is required. The power-up menu will display
CRYPT-OK if an encryption module is found. In addition the
modem
should have a software version 7.10 or higher. In
asynchronous communication no extra hardware are required,
however the encryption module will increase the throughput
considerable for the higher speeds (9600 and above).
