cb – callback security
The callback functionality makes the established link more secure. After an incoming call
the adapter will make a callback to either a preconfigured number or to the incoming
number. The callback can be protected by a password. The unit can also be configured for
a secure access without callback.
If the password is enabled, the calling part will be prompted for the password directly
after connection. When the password is entered correctly, the adapter will disconnect the
current link and make a callback after a preconfigured number of seconds (configurator
command: capa [default 3]).
If the unit is configured as ”secure access”, it will allow data only after the password is
correctly entered.
After 3 retries of entering wrong password or after 60 seconds, the link will be discon-
nected and the callback/secure access aborted.
The number to callback must be entered in the catab number table (catab1, catab2
or catab3).
The passwords is stored in: cbpwd1, cbpwd2 or cbpwd3.
When making a callback to a number stored in catab, the password in cbpwd1 is
connected to the number in catab1 (and cbpwd2 to catab2 and cbpwd3 to catab3)
A callback to an analogue modem can be done with ID90-V90 and by storing an ’#’
before the number in catab. (see also the catab command in this manual)
For an even more secure connection please also refer to the acctab command.
Callback control:
0: callback disabled (default)
1: callback enabled, No password needed, callback number only in
position1 in catab (catab1)
2: callback enabled, No password needed, callback to incoming number
3: access security enabled, Password in one or more positions in
cbpwdx (x= 1,2 or 3)
4: callback enabled, Password in one or more positions in cbpwdx
(x= 1,2 or 3), callback to number in catab, (cbpwd1 corresponds to
catab1…)
5: callback enabled, Password in one or more positions in cbpwdx
(x= 1,2 or 3), callback to incoming number
6: callback enabled, Password in one or more positions in cbpwdx
(x= 1,2 or 3), callback to number that is entered after password
check is OK.
