ConditionsCAUTIONThere is a risk that fraudulent telephone calls will be made if a third party discovers a personal identificationnumber (PIN) (verification code PIN or extension PIN) of the PBX. The cost of such calls will be billed tothe owner/renter of the PBX. To protect the PBX from this kind of fraudulent use, we strongly recommend:a. Keeping PINs secret.b. Selecting complex, random PINs that cannot be easily guessed.c. Changing PINs regularly.• Extension PIN LockIf the extension PIN is entered incorrectly three times, the line will be disconnected. If an incorrect PIN isentered a preprogrammed number of times, the PIN will be locked. Only an extension assigned as amanager can unlock a PIN, after which it will be reset. In this case, the PIN will be unlocked and cleared.This feature is also known as Station Password Lock.• Remote Extension PIN ClearIf an extension user forgets his or her PIN, a manager can clear (reset) the PIN, and the extension usercan assign a new PIN.• Extension PIN DisplayIt is possible to select whether to show the extension PIN on the display through system programming. Bydefault, it is shown as dots.PC Programming Manual References4.5 [2-3] Timers & Counters—Miscellaneous— Extension PIN—Lock Counter4.9 [2-6-1] Numbering Plan—Main—Features— Extension PIN Set / Cancel4.18 [2-9] System Options—Option 1— PT LCD—Password / PIN Display6.1 [4-1-1] Wired Extension—Extension Settings—Main— Extension PIN6.10 [4-2-1] Portable Station—Extension Settings—Main— Extension PINPT Programming Manual References[005] Extension Personal Identification Number (PIN)Operating Manual References3.1.2 Personal Programming3.2.2 Manager Programmingf5.1.7 Extension Port ConfigurationDescriptionThere are three types of extension ports, used to connect digital proprietary telephones (DPTs), analogproprietary telephones (APTs), single line telephones (SLTs), Cell Stations (CSs), DSS Consoles, and VoiceProcessing Systems (VPS) to the PBX.
