■Station Message Detail Recording (SMDR). This system management feature keeps track of incoming and outgoing calls and prints out reports on a printer attached to your control unit. It also prints programming reports that can alert you to tampering with the system. Inspect these reports frequently. (Call Accounting System applications also provide a utility for detecting toll fraud. See Table 4–12 on page 4-57.)

Toll fraud is a growing criminal industry, and there are individuals who have made a science of defrauding businesses of millions of dollars. You should strongly caution users against the following practices that can compromise the security of the system:

■Writing down barrier codes or passwords and keeping them in a wallet or purse

■Making remote access calls or other password-protected calls from public telephones in such a way that they can be viewed by others, who may even use telescopes or binoculars to see the digits as they are dialed

■Sharing barrier codes or passwords with others or saying them out loud in public locations

■Programming passwords or barrier codes on telephone buttons inside or outside the system

For more information about security, see ‘Remote‘ Access’’ on page 4-53 and
