BCM 4.0 Networking Configuration Guide
Remote users can access system lines, line pools, the Page feature, and remote administration. The
exact facilities available to you through remote access vary depending on how your installer set up
your system.
External access tones
You can hear some of the following tones when accessing BCM from a remote location. Table 103
shows the different types of tones and what they mean.
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).
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.
