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.
Users should memorize their COS passwords instead of
writing them down. Typically, each user has a separate
password. Several users can share a password or one user can
have several passwords.
Individual COS passwords should be deleted when an
employee leaves the company. Group COS passwords should
be changed if one of the group members leaves the company.
Changing your Class of Service
You must enter a Class of Service password each time you
want to make a call that is normally restricted on a line or
telephone.
To change the restriction filters on a line or telephone:
1. Press
²ß¡.
2. Enter your six-digit COS password.
COS passwords allow you to define individual passwords and
determine the restriction filters, and remote package
associated with each.
