Using Class of Service (COS) passwords
Class of Service passwords permit controlled access to system 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.
Users should memorize their COS passwords instead of writing them
down. Employee COS passwords should be deleted when they leave the
company. Typically, each user has a separate password. Several users can
share a password or one user can have several passwords.
