A flexible button on a DSSConsole can be customised as an SDN button.• An extension can have up to eight PDN buttons.• If none of an extension’s PDN buttons are idle, the extension will not receive incoming calls, including CallWaiting. Therefore, it is strongly recommended for PDN extensions to have at least three PDN buttons.• Through COS programming, it is possible to select whether extensions can create SDN buttons on theirown extensions using PT programming.• Up to eight different extensions can assign SDN buttons corresponding to the same PDN extension.• When a PDN extension has an idle CO button or ICD Group button, calls will arrive on the following buttonsaccording to the following priority:– Incoming intercom calls to an ICD group: ICD Group button ® PDN button– Incoming trunk calls: S-CO button ® G-CO button ® L-CO button ® PDN button– Incoming trunk calls to an ICD group: ICD Group button ® S-CO button ® G-CO button ® L-CO button® PDN button• When multiple calls of the same status (e.g., on hold) are on a PDN extension, the status of the newestcall will be displayed on the corresponding SDN extensions. For example, if a PDN extension has two callsringing, an SDN extension will answer the call that arrived at the PDN extension last, when pressing theSDN button.• When a PDN extension is a member of an ICD group in Ring Distribution method, and an incoming callarrives at the ICD group, the incoming call status will not appear on the LEDs of the corresponding SDNextensions (® 1.2.2.1 Incoming Call Distribution Group Features—SUMMARY).104 Feature Guide1.7.1 Primary Directory Number (PDN)/Secondary Directory Number (SDN) Extension
