Notes about COS passwords
The COS password can define the set of line pools that may be accessed and whether or not the
user has access to the paging feature.
The class of service (COS) that applies to an incoming remote access call is determined by:
• the filters that you apply to the incoming trunk
• the COS password that the caller used to gain access to Business Communications Manager.
• in cases where DISA is not automatically applied to incoming calls, the remote caller can
change the class of service by dialing the DISA DN and entering a COS password.
Remote users can access system lines, line pools, the Page feature, and remote administration (if
enabled through Software Keys). The exact facilities available to you through remote access vary
depending on how your installer set up your system.
Note: If the loop start line used for remote access is not supervised, auto-answer does not function
and the caller hears ringing instead of a stuttered tone or the system dial tone.

Security note:
COS password security and capacity
• Determine the COS passwords for a system randomly and change them on a
regular basis.
• Users should memorize their COS passwords and keep them private.
Typically, each user has a separate password. However, several users can
share a password or one user can have several passwords.
• Delete individual COS passwords or change group passwords when
employees leave the company.
• A system can have a maximum of 100 six-digit COS passwords (00 to 99).
You can copy the restriction filters and remote package from one COS
password to another. COS passwords must be unique.
To maintain the security of your system, the following practices are recommended:
• Warn a person to whom you give the remote access number to keep the
number confidential.
• Change COS passwords often.
• Warn a person to whom you give a COS password, to memorize the password
and not to write it down.
• Delete the COS password of a person who leaves your company.

Security note: Remote users can make long distance calls.
Remember that a remote user can make long distance calls that are charged to your
company. They can also access line pools and make page announcements in your office.
