A Panasonic KX-TD7680 or KX-TD7690 portable station (PS) can be used in place of a proprietary telephone (PT), providing wireless access to PBX features and call handling.

Registration

Before a PS can be used, it must be registered with the PBX through system programming (

PS Registration [690]) and assigned an extension number.
Because a PS transmits radio waves, it is possible that a PS belonging to a neighboring PBX can be registered 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. (

Personal Identification Number (PIN) for PS Registration [692]). This PIN, if programmed, is only used during the PS registration process.
Each PS can be registered to more than one PBX if necessary, and registration can be canceled if a PS will no longer be used with one of these PBXs. (

PS Termination [691])

Connection

There are two ways a PS can be used.

As an Extension
A PS is assigned its own extension number when it is registered to a PBX. The PS can use this extension number to make and receive calls, just as a wired telephone can. A PS can be a member of an 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 way for several PSs to be notified of an incoming call simultaneously, but does not offer all of the features provided by an ICD group. (

1.2.2 Incoming Call Distribution (ICD) Group Features)

In Wireless XDP Parallel Mode
A PS can share an extension number with a wired telephone, allowing extension users to use their PSs when they are away from their desks to answer or make calls as if they were using their wired telephones. (

1.22.3 Wireless XDP Parallel Mode)

PS Interaction with CS

Each PS communicates with the PBX wirelessly through a cell station (CS). Each CS is connected to the PBX and sends and receives radio waves to and from different PSs within its range, using different channels for different PSs. Each CS has three channels, i.e., up to three calls (conversations) can be handled 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 the same PBX to offer a greater area of wireless coverage. Additionally, a PS does not need to be used with 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.

Handover
If a PS is within range of more than one CS, the PS will communicate with the CS which has the greatest signal strength and an available channel. When a PS user moves out of range of one CS and moves in range of another 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 during the 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).

[Example of Handover]

Handover is not possible when the PS is:

a)	Not within range of another CS.
b)	Within range of another CS but that CS is busy.
c)	On a conference call. ( 1.13.1 Conference Features)
d)	Screening a call via Live Call Screening (LCS) or recording a call via Two-way Record ( 1.21.2 Voice Mail DPT (Digital) Integration)
e)	Paging other extensions. ( 1.14.1 Paging)
f)	On a doorphone call.
g)	Dialing digits to make a CO line call.
h)	On a call with an extension which is recording the conversation via PC Console or PC Phone.

•	If every CS that a PS is in range of is busy when that PS is called, the call will not be connected and the caller will hear a busy tone.

Installation Manual

2.8 Connection of 2.4 GHz Portable Stations

A PS ring group is a way for several portable stations (PSs) to be notified of an incoming call simultaneously, while using only one channel of a cell station (CS).
Normally when a PS receives a call, one channel of a CS is used to ring the PS (

1.22.1 Portable Station (PS) Connection). If several PSs are members of an incoming call distribution (ICD) group, the available channels of a CS will become busy just by ringing each PS. Assigning a group of PSs to a PS ring group alleviates this strain on the CS because only one channel is needed to ring a PS ring group's members.
PS ring group members and related parameters are assigned through system programming, as explained below.

a)	Floating Extension Number: When this number is called, all PSs in the group ring.
b)	Group Name: Can be displayed on a ringing PS to indicate that the incoming call is a group call, and not a call directed to the PS's extension number.
c)	Incoming CO Line Call Information Display: Determines which information is shown on the PS display when a group call is received. Select "`Caller ID`" to display the caller's telephone number or name, or "`Called Number`" to display the name of the PS ring group which is receiving the call.
d)	Member PSs: Select each PS that will be a member of the corresponding PS ring group. Note that a PS can belong to more than one PS ring group.

[Programming Example: PS Ring Group]

[Example of PS Ring Groups 1 and 2]

Explanation:

PS Ring Group 1
PS 1, PS 2, and PS 3 will ring simultaneously when a call is directed to floating extension number 301, and will display the Caller ID information for the call.
These PSs will ring individually when a call is directed to their assigned extension numbers (programming not shown here).

PS Ring Group 2
PS 3, PS 4, and PS 5 will ring simultaneously when a call is directed to floating extension number 302, and will display "Sales 2".
These PSs will ring individually when a call is directed to their assigned extension numbers (programming not shown here).

ICD Groups vs. PS Ring Groups
Assigning PSs to either an ICD group or a PS ring group will allow multiple PSs to receive group calls simultaneously. The differences between the two are highlighted below:
Features
PS Ring Group
ICD Group
Members can ring simultaneously when a call is received
Calls can be distributed to member extensions using different methods
The CS is less likely to be busy; ringing all member PSs uses only one CS channel
Members can log-in, log-out, and use Wrap-up time, G-DN button
Both PTs and PSs can belong to the same group
Each member can belong to more than one group
Calls can wait in a queue if they can not be answered
[Example of CS Channels Used for PS Ring Group Calls and ICD Group Calls]
Explanation:
The PS ring group has six members which are in range of two different CSs. When a call arrives, each CS uses one channel to ring all member PSs within its range.
The ICD group has one proprietary telephone (PT) member, as well as six PS members which are in range of two different CSs. When a call arrives, each CS uses all three of its channels to ring each of the member PSs within its range.

•

A maximum of 32 PS ring groups can be programmed.

•

Each member of a PS ring group must be a PS, but each member does not need to be in range of the same CS. When a call is directed to a PS ring group, all CSs connected to the PBX will try to ring members of the group.

•

PS ring groups do not have Log-in or Log-out features. There is no way for a PS to log-in to or log-out from a PS ring group.

•

A PS ring group may be assigned as a member of an ICD group, but the PS ring group cannot log-in to or log-out from an ICD group. The PS ring group (and therefore its members) will always be logged-in.

•

When a PS is assigned to a PS ring group, the following settings are used if it receives a call directly, but are disregarded when it receives a group call:

a)	Delayed Ringing (All PSs will ring simultaneously.)
b)	The incoming call display preference assigned to the PS through system programming.
c)	Features set on the PS, such as Call Forwarding (FWD). Note, however, that if a PS user has set Do Not Disturb (DND), that PS will not ring for group calls either.

•

When a call is directed to a PS ring group, the PBX will try to ring the group's members regardless of whether or not they are already on another call. If all members of a PS ring group are busy when the group is called, their PSs will not ring but the caller will hear a ringback tone.

•

A PS ring group will only ring one call at a time on its member PSs. If a PS ring group is ringing one call when another call is directed to the group, the group will appear busy to the caller. If a call is directed to a specific PS within the group in this situation and the PS is available to answer calls, the PS will ring as usual.

•

Although each CS has three channels (i.e., can handle three conversations at once), the PBX will ring calls for only two PS ring groups at a time. In other words, if two calls directed to two different PS ring groups are ringing, no other PS ring group calls will ring until one of the other ringing calls is answered. This leaves one CS channel available for other calls.

•

If a PS in a PS ring group has set the DND feature for CO line calls, the PS will not ring for CO line calls as well as intercom calls directed to the group.

•

Compatible PS
A Panasonic KX-TD7680 and KX-TD7690 can be assigned to PS ring groups.

A portable station (PS) can be used in parallel with a wired telephone, i.e., a digital proprietary telephone (DPT), analog proprietary telephone (APT), or single line telephone (SLT), allowing an extension user to make or receive calls with either the wired telephone or the PS. The PS will use the same extension number as the wired telephone, and many of the wired telephone's extension settings (Call Forwarding [FWD], Class of Service [COS], etc.) are also used by the PS.
This mode is similar to XDP Parallel mode used to pair DPTs with SLTs. (

2.1.1 Extension Port Configuration)
In order to use a PS in Wireless XDP Parallel mode, the mode must be turned on using the PS.

[Example of Wireless XDP Parallel Mode, XDP Parallel Mode]

•

Whether or not a PS is allowed to pair itself with a wired telephone is determined by the COS assigned to the extension number of the wired telephone. (

Wireless XDP Parallel Mode for Paired Telephone [515])

•

Wireless XDP Parallel mode can be turned on or off using the PS only.

•

To switch between the wired telephone and the PS during a conversation, simply go off-hook with the other telephone. The call will not, however, be switched when the extension is:

a)	Engaged in a conference call. ( 1.13.1 Conference Features)
b)	Screening a call using Live Call Screening (LCS) or when recording a conversation using Two-way Record. ( 1.21.2 Voice Mail DPT (Digital) Integration)
c)	Receiving an Off-hook Call Announcement (OHCA). ( 1.7.4.3 Off-hook Call Announcement (OHCA))
d)	Being monitored by another extension. ( 1.7.3 Call Monitor)
e)	When the extension has a call on consultation hold. ( 1.12.5 Consultation Hold)

•

When a PS in Wireless XDP Parallel mode is on a call, other extension users cannot perform the following features when they call this extension:

—

Automatic Callback Busy

—

Executive Busy Override

—

Whisper OHCA (

1.7.4.4 Whisper OHCA)

•

When a PS is paired with a wired telephone, most of the extension settings assigned to the wired telephone (extension number, extension name, etc.) will be used by the PS, and the PS will use its own extension settings once again when Wireless XDP Parallel mode is canceled. Note, however, that the following extension settings of the wired telephone are copied to the extension settings of the PS when Wireless XDP Parallel mode is activated, and will remain in effect for the PS after the mode is canceled.

If an extension number is required when changing any PS settings while in Wireless XDP Parallel mode, use the original extension number assigned to the PS, not the extension number of the paired (wired) telephone.

•

If the Extension Feature Clear is performed, the corresponding extension data for both the wired telephone and the PS will be cleared. (

1.24.2 Extension Feature Clear)

•

When a call arrives, both the wired telephone and the PS will ring. However, when one of the following settings is made, only the telephone which was used to make the setting will ring.
