Customer Support Information
To reduce the risk of unauthorized access through Remote Administration and
Maintenance, please observe the following procedures:
The System Administration and Maintenance capability of a Hybrid/PBX or
Key system is protected by a password.
— Change the default password immediately.
— Continue to change the password regularly.
— Only give the password to people who need it and impress upon them
the need to keep it secret.
— If anyone who knows the password leaves the company, change the
password immediately.
If you have a special telephone line connected to your Hybrid/PBX or Key
system for Remote Administration and Maintenance, you should do one of
the following:
— Unplug the line when it is not being used.
— Install a switch in the line to turn it off when it is not being used.
— Keep the Remote Administration and Maintenance telephone number
secret. Only give it to people who need to know it, and impress upon
them the need to keep it a secret. Do not write the telephone number
on the Hybrid/PBX or Key system, the connecting equipment, or
anywhere else in the system room.
If your Remote Administration and Maintenance feature requires that
someone in your office transfer the caller to the Remote Administration
and Maintenance extension, you should impress upon your employees
the importance of only transferring authorized individuals to that
extension.
