13.1.27 PS (Portable Station)DescriptionA Panasonic portable station (PS) can be used in place of a proprietary telephone (PT), providing wirelessaccess to PBX features and call handling.Cell Stations (CSs) allow PSs to receive reception within a designated area.1. RegistrationBefore a PS can be used, it must be registered with the PBX through system programming and assignedan extension number.® 3.47 [1-2] Portable Station—PS Registration and De-registration— Registration® [690] PS RegistrationBecause a PS transmits radio waves, it is possible that a PS belonging to a neighboring PBX can beregistered to your PBX. To prevent this sort of unauthorized registration, a personal identification number(PIN) can be programmed for this PBX that must be entered on the PS during registration. This PIN, ifprogrammed, is only used during the PS registration process.® 3.47 [1-2] Portable Station—PS Registration and De-registration— Personal Identification Number® [691] PS TerminationEach PS can be registered to more than one PBX if necessary, and registration can be canceled if a PSwill no longer be used with one of these PBXs.® 3.47 [1-2] Portable Station—PS Registration and De-registration— De-registration® [692] Personal Identification Number (PIN) for PS Registration2. ConnectionThere are two ways a PS can be used.As an ExtensionA PS is assigned its own extension number when it is registered to a PBX. The PS can use this extensionnumber to make and receive calls, just as a wired telephone can. A PS can be a member of an incomingcall distribution (ICD) group, can be assigned as the destination for redirected calls, etc., just as a wiredtelephone can.A PS can also be a member of a PS ring group (® 13.1.31 PS—Ring Group). A PS ring group is a wayfor several PSs to be notified of an incoming call simultaneously, but does not offer all of the featuresprovided by an ICD group. (® 9.1.1 ICD GROUP FEATURES)In Wireless XDP Parallel ModeA PS can share an extension number with a wired telephone, allowing extension users to use their PSswhen they are away from their desks to answer or make calls as if they were using their wired telephones.(® 20.1.5 Wireless XDP Parallel Mode)3. PS Interaction with CSEach PS communicates with the PBX wirelessly through a cell station (CS). Each CS is connected to thePBX and sends and receives radio waves to and from different PSs within its range, using different channelsfor different PSs.A PS must be within range of a CS in order to be used, however, multiple CSs can be used with the samePBX to offer a greater area of wireless coverage. Additionally, a PS does not need to be used with a specificCS; any PS can communicate with any CS provided the PS is registered to the PBX, and provided the CShas at least one channel available.HandoverIf a PS is within range of more than one CS, the PS will communicate with the CS which has the greatest signalstrength and an available channel. When a PS user moves out of range of one CS and moves in range ofanother CS, the PS will "hand over" its communications to the new CS. Handover is possible when:a. The PS is on an intercom call or on a call with an outside party. (The call will not be disconnected duringthe handover.)b. A call is ringing at the PS. (The call will continue to ring after the handover.)c. The PS is in idle status (i.e., waiting to receive calls).Document Version 2013-05 Feature Manual 28713.1.27 PS (Portable Station)
