6NOTE: Outgoing DISA calls are controlled by the dialing class of the station identi-fied by the security code.The DISA line must have disconnect supervision from thecentral office. Insist that this service is verified by your installation/service company.DISA SECURITYA common practice among hackers is to repeatedly dial a known DISA accessnumber (usually with a computer) and try a different passcode each time. Thehacker hopes to eventually chance upon the correct passcode and thus gainaccess to your system. The OfficeServ 100, OfficeServ 500, and OfficeServ 7000Series security feature counts the number of sequential incorrect passcodeattempts. If a certain number is reached, DISA is disabled and the system sends analarm to designated display stations. The number of passcode attempts and thedisable duration are both programmable. In addition, the OfficeServ 100,OfficeServ 500, and OfficeServ 7000 systems will print an SMDR record (a cus-tomer-provided printer is required) each time an incorrect passcode is entered.The DISA alarm will ring for a programmable time before canceling the ringing;however, the DISA alarm display will remain until the alarm is cleared. To clear theDISA alarm, follow the following procedure:• Lift the handset and dial 58.• Enter the DISA alarm passcode (see your service company).• Replace the handset.WARNINGAs it is impossible to prevent unauthorized access to your telephone sys-tem by hackers, we suggest that you do not turn the DISA feature on unlessyou intend to use it. If you do use this feature, it is good practice to fre-quently change passcodes and periodically review your telephone recordsfor unauthorized use.FORCED ACCOUNT CODESVERIFIEDWhen set for this option the user must enter an account code for all outgoing calls.The account code entered will be verified from a system list.
