1.22 Portable Station (PS) Features166 Feature Guide1.22 Portable Station (PS) Features1.22.1 Portable Station (PS) ConnectionDescriptionA Panasonic KX-TD7680 or KX-TD7690 portable station (PS) can be used in place of a proprietarytelephone (PT), providing wireless access to PBX features and call handling.1. RegistrationBefore a PS can be used, it must be registered with the PBX through system programming (→ PSRegistration [690]) and assigned an extension number.Because 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 identificationnumber (PIN) can be programmed for this PBX that must be entered on the PS during registration. (→Personal Identification Number (PIN) for PS Registration [692]). This PIN, if programmed, is only usedduring the PS registration process.Each PS can be registered to more than one PBX if necessary, and registration can be canceled if aPS will no longer be used with one of these PBXs. (→ PS Termination [691])2. 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 thisextension number to make and receive calls, just as a wired telephone can. A PS can be a member ofan incoming call distribution (ICD) group, can be assigned as the destination for redirected calls, etc.,just as a wired telephone can.A PS can also be a member of a PS ring group (→ 1.22.2 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. (→ 1.2.2 Incoming Call Distribution (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 wiredtelephones. (→ 1.22.3 Wireless XDP Parallel Mode)3. PS Interaction with CSEach PS communicates with the PBX wirelessly through a cell station (CS). Each CS is connected tothe PBX and sends and receives radio waves to and from different PSs within its range, using differentchannels for different PSs. Each CS has three channels, i.e., up to three calls (conversations) can behandled simultaneously by one CS.A PS must be within range of a CS in order to be used, however, multiple CSs can be used with thesame PBX to offer a greater area of wireless coverage. Additionally, a PS does not need to be usedwith a specific CS; any PS can communicate with any CS provided the PS is registered to the PBX,and provided the CS has at least one channel available.
