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. Employees’ 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.

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

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.

If you use your Norstar system from outside the 

office, you may have to enter a Class of Service password 
to gain access to the system. See “Using your Norstar 
system from an external location” on page 184.
