Remote Administration and Maintenance
The Remote Administration and Maintenance feature of your
telecommunications system, if you choose to use it, permits users to change the
system features and capabilities from a remote location.
The Remote Administration and Maintenance feature, through proper
administration, can help you reduce the risk of unauthorized persons gaining
access to the network. However, telephone numbers and authorization codes
can be compromised when overheard in a public location, are lost through theft
of a wallet or purse containing access information, or through carelessness
(writing codes on a piece of paper and improperly discarding them).
Additionally, hackers may use a computer to dial an access code and then
publish the information to other hackers. Substantial charges can accumulate
quickly. It is your responsibility to take appropriate steps to implement the
features properly, evaluate and administer the various restriction levels, and
protect and carefully distribute access codes.
Under applicable tariffs, you will be responsible for payment of toll charges.
AT&T cannot be responsible for such charges and will not make any allowance
or give any credit resulting from unauthorized access.
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 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
