Chapter 5: Configuration
Remote Supervision
The ISU 512 has the ability to be remotely accessed and configured from an-
other ISU 512. The originating ISU 512 can remotely access another ISU 512
using a smart dial string with a #6 suffix.
The ISU 512 can be protected from illegal access by using the password pro-
tection built into the remote protocol. The Supervision (SPV) password can be
accessed in the menu tree at:
3=CONFIG
1=Netw. options
1=Dial Line
8=Passwords
1=SPV Password
The smart dial string format for this type of call is as follows:
<number>#6#<password>
For example, the dial string 9224323#6#4321 places a remote supervisory call
to the remote unit and sends the 4321 string as the SPV password. If the re-
mote unit's SPV password matches the request is accepted. If the password
does not match, the call is terminated by the remote unit. The remote unit
places Inv Password in the status buffer.
During remote SPV, the remote unit can be accessed via the front panel or the
VT 100/maintenance port interface. While in remote SPV, the maintenance
port prompt changes from the --512--> to the --REM--> prompt. The VT 100
screens change to signify any configuration changes being passed to the re-
mote unit. The originating unit's configuration is not changed while a remote
SPV is in progress.
The password may be up to six alphanumeric characters in length. If no SPV
password is entered, the unit is unprotected and all attempts at remote config-
uration are accepted.
