Using Class of Service (COS) passwords

Class of Service passwords permit controlled access to a
system's resources both by internal and remote users. When
you enter a Class of Service password at a telephone, the
restriction filters associated with your Class of Service
password apply, rather than the normal restriction filters.
Similarly, when a remote user enters a Class of Service
password on an incoming auto-answer line, the restriction
filters and remote package associated with their Class of
Service password apply, rather than the normal restriction
filters and remote package. COS passwords are programmed
by either your customer service representative or installer.
