Te r m i n a l  Ty p e
nSetting the type in the station screen to XMOBILE will identify an X-mobile 
station.
Signaling Group administration
nNew field X-Mobility/Wireless Type is added to the signaling group form to 
indicate the type of X-mobile endpoints allowed for it (DECT or NONE). 
nThe default for the field is NONE.
nThe X-Station capability is turned off unless specifically enabled in the 
special applications form.
Signaling
nISDN PRI is modified to allow INFO messages with Display Information 
Elements to be sent at any time. 
nISDN PRI is also modified to allow INFO messages with Keypad Facility 
Information Elements to generate DTMF when the special application is 
enabled.
nThe X-mobile station is treated as an analog station in terms of feature 
interactions except as noted in previous requirements.
Description
nWhen a call comes into a station administered to be X-mobile, the software 
checks for a trunk group associated to the station. 
— It then signals the call to that station using that trunk group. 
nVery similar to how incoming calls are handled for BRI stations.  Add signaling-group

nWhen a call comes in from a trunk group marked as having X-mobile 
endpoints, the SETUP message is checked for a CALLING PARTY 
NUMBER Information Element. 
— If present, and if it matches the extension of a station marked as X-
mobile, that call is re-stimulated as an internal call originating from 
the X-mobile station.
Calling Capabilities
nAdministration of an X-mobile station allows an administrator to customize 
call options, based on the parameters for an analog station.
Call Detail Recording
nA Call origination from an X-mobile WT is present in the CDR as a call 
origination from the X-mobile station. 
nA Call Termination to an X-mobile WT presents as a call termination to the 
X-mobile station in the CDR.
Xmobile to Trunk mapping 
nNo limit to the number of X-mobile stations that can be supported per Trunk 
Group.
Call Coverage
nThe X-mobile station is allowed to cover calls not answered by the X-
mobile, either Ring No Answer or Subscriber Absent, when coverage is 
administered for the X-mobile station.
NOTE:
If remote coverage is administered for an X-mobile station, it then 
must be the last point of coverage.
Capacity Constraints and Feature Limitations
nThe X-Station Mobility works only when stations are remoted over ISDN 
trunks. 
nAn X-mobile station counts as wired DEFINITY® station in terms of station 
limits and configuration consideration.
Memory Impact of Capacity Changes
nThe X-mobile capability is administered on the station admin screen
nIt is implemented in such a way as to 
not increase the memory required on 
a per station basis.

Scenarios
nAll feature operations are intended to work exactly as if the X-mobile 
station were directly connected to the DEFINITY® System. 
nAnalog type feature operation were chosen, since most wireless terminals 
support only flash operations and are not multi-appearance or context 
sensitive. 
nIn almost all cases, the operation expected for an X-mobile station is 
identical to a similarly administered analog station.
XStation Mobility (MWL)
nAllows the DEFINITY® system to control and manage handsets not directly 
connected to the DEFINITY® system as if they were directly connected 
wired stations. 
nThe handset may have bridged appearances on wired terminals and thus 
be able to use DEFINITY® system features like call forwarding and call 
pickup. 
nIcon-based message waiting update is also supported. 
nAchieved by using the DEFINITY® system’s Administration Without 
Hardware (AWOH) capability and extending it to actual signal remote 
points.
Description
nWhen a call comes into a station administered to be X-Mobile, the software 
checks for a trunk group associated to the station. 
nIt then signals the call to that station using that trunk group. 
— Similar to how incoming calls are handled for BRI stations. 
nMWI Activation and Deactivation messages are exchanged between the 
DEFINITY® system and the DAS to update MW status on the X-Mobile 
WTs.
nUpon successful location registration of an X-Mobile WT, the DAS sends a 
location registration indication message to the DEFINITY® system. 
— Sends back an MWI Activation or Deactivation message back to the 
DAS to refresh the X-Mobile WT’s MW status. 
nDepending on the level of support on the X-Mobile WT, a detach indication 
may be sent to the DEFINITY® system indicating that the WT has left the 
system. 
— The DEFINITY
® system ignores this indication until further definition 
of this capability is available.

NOTE:
If the X-Mobile trunk does not return alerting, and instead returns a 
disconnect or release, the DEFINITY® system software advances to the 
next coverage point, if administered.
If the next coverage point is not administered, DEFINITY
® system 
software disconnects ringback tone and present busy tone. 
On an ISDN interface, after XX seconds of busy tone, a disconnect with 
cause SUBSCRIBER ABSENT (17) is passed if the originator was ISDN.
nAllows phones remote over a trunk interface to be controlled by the 
DEFINITY® system as if they were directly connected to it. 
nAccomplished by administering a station record for each station to be 
controlled as type X-Mobile. 
nThese X-Mobile stations have additional administration information further 
describing the capabilities of the remote station. 
nEach X-Mobile station has an associated Trunk Group. 
nIf the call or other signal needs to be sent to it, the DEFINITY® system uses 
the associated D-Channel to communicate with the remote terminal. 
nWhen a call arrives over a D-Channel which carries X-Mobile traffic, that 
call is analyzed to check if an X-Mobile remote station originated it.
— If it was, then the call is re-associated in call processing as an 
internally originated call from the local X-Mobile station. 
— Allows a large number of DEFINITY
® system features to work for 
the remotely controlled station, including bridging. 
nIcon-based message waiting enables X-Mobile WT users to check for 
messages while idle instead of the display-based message waiting feature 
that only informs status while on a call. 
— When message is waiting at an idle X-Mobile WT, its switch-hook 
icon flashes. 
nBoth types of message waiting indication can co-exist in a system.
Administration
Enabling X-Station Mobility
nNew field Maximum XMOBILE Stations is created on the Customer 
Options form and defaults to 0. 
nWhen this field is set to 0, the feature is disabled. 
nIt is only possible to set the field to N > 0 if the system is administered as 
R8 or later.

Station form indicates MWI update type
nThe Message Waiting Type field on the station form indicates the mode of 
MWI update to the WT. 
nThe MWI activation/deactivation message is used when the field is set to 
ICON. 
nThe MW is attached to the end of the display line during an incoming or 
outgoing call if the field is set to DISP.
nNo MWI update is sent if the field is set to NONE.
Mobility Trunk Group field on station form changes 
nThis Mobility Trunk Group field is updated dynamically.
nIf the field is changed through the change command instead of the add 
command, the following warning message appears on the SAT:
Overriding this field may cause failure in 
delivering incoming calls to this station.
nIn a multiple DAS configuration, the Mobility Trunk Group field may change 
without user intervention after the last form submittal. 
nAs an X-Mobile WT roams among the DASs, it sends a location registration 
indication message to the DEFINITY® system through the signalling link of 
the trunk group associated with the particular DAS. 
nThis informs the DEFINITY® system to deliver incoming calls to the station 
through the updated trunk group’s signalling link. 
— If this is overridden, incoming calls may be sent to a DAS that the X-
Mobile WT is not currently registered to.
Signaling Group administration
nNew field has been added to the signaling group form to indicate the type 
of X-Mobile endpoints allowed for it (DECT or NONE). 
nThe default for the field is NONE.

nIf the administered software version is V5 or earlier this feature cannot be 
enabled.
nThe only form that includes new fields is the signaling group form. The new 
field is defaulted to none on upgrades. 
nThe feature must be enabled from the customer options screen. If number 
of X-Mobile Stations is set to N > 0, then X-Station Mobility is enabled for 
this system.
nX-Mobility functionality requires that ISDN PRI is also enabled.
Capacity Constraints and Feature Limitations
nThe X-Station Mobility only works when stations are remote over ISDN 
trunks. 
nAn X-Mobile station counts as a wired DEFINITY® system station in terms 
of station limits and configuration consideration.
Call Processing
Basic Call Termination
nA call for an X-Mobile station looks up the current trunk group associated 
with the X-Mobile station.
nIt then extends the call over the trunk group to the remote station.
NOTE:
For PRI trunks, this involves sending a setup message with a calling 
party number and a called party number indicating the extension 
number of the X-Mobile WT.
Basic Call Origination
nA call from an X-Mobile station appears to DEFINITY® system Call 
Processing to have been locally originated by that station. 
nDEFINITY® associates call origination to X-Mobile stations by analyzing 
the CALLING PARTY NUMBER Information Element in the SETUP 
message received over an ISDN trunk marked as having X-Mobile 
endpoints and matching the number with the extension of an X-Mobile 
station.
NOTE:
The X-Mobile station is modeled as an analog station as far as a 
DEFINITY® system’s internal call structures are concerned. The calling 
party number is the X-Mobile station’s extension number. Digit 
modification is not required.

Flash Operation
nIf an INFO message containing a KeyPad Facility Information Element of 
the value 0x15 or values 0x1B, 0x48, the message is interpreted as a 
Flash-hook operation from the remote station.
NOTE:
These values are defined by the ETSI DECT GAP standard and the 
RCR-28 PHS standard.
Bridged Appearances
nAn X-Mobile station can have bridged appearances on wired stations, or be 
a bridged appearance of a station. 
— Those bridge appearance status LEDs reflect the status of the X-
Mobile station. 
nThe X-Mobile station is able to bridge on or off calls at will, just like any 
bridge of a directly connected wired station.
NOTE:
When a wired phone has a bridged appearance of an X-Mobile, it is an 
analog bridge. 
When the X-Mobile is a bridge of another phone, it is a digital button 
bridge.
Call Progress Tones
nWhen an X-Mobile station is on a call, the DEFINITY® system provides 
local call progress tones for that call
— Dial Tone
— Alerting
— Coverage Tone
—Busy
— Re-order
— Custom Alert
— Call Waiting Tone
— Call Prompting Tone
— Confirmation Tone
— Stutter Dial Tone

Display
nWhen an X-Mobile station is ringing or active, an ISDN Info message is 
used to update its display whenever appropriate. 
nThe display for an X-Mobile station is limited compared with standard 
DEFINITY® system displays. 
nThe length is limited to 15 characters. 
nOther than the optional message waiting indication, display information is 
limited to calling/called party names or numbers. 
nThere are no redirection indications nor conference displays.
Called Party Name
nWhen an X-Mobile station calls another par ty, the DEFINITY® system 
provides to the X-Mobile WT the name administered for the called party via 
an ISDN info message.
Connected Party
nWhen call processing would normally update a station’s display with text 
information (such as the connected party), it sends that information to the 
X-Mobile station in an INFO message contained in a DISPLAY Information 
Element.
Calling Party Number
nCalling Party Number is sent to the X-Mobile station when available. 
The calling party number is not displayed when the number is restricted from 
display as defined by DEFINITY
® system translation.
X-Mobile to Trunk mapping
nThere is no limit to the number of X-Mobile stations that can be supported 
per Trunk Group.
NOTE:
The number of simultaneous calls supported by the interface is limited 
to the number of trunks assigned to an X-Mobile trunk group.
Call Coverage
nThe X-Mobile station is allowed to cover calls not answered by the X-
Mobile, either Ring No Answer (RNA) or Subscriber Absent, when 
coverage is administered for the X-Mobile station. An X-Mobile station is 
also allowed to be a coverage point.

Calling Party Name
nThe X-Mobile station sends the calling party name information in a 
DISPLAY Information Element whenever normal call processing for that 
station would update the display of the station to indicate the calling par ty.
NOTE:
After connect, an INFO message overrides the handset operation of 
the display in order to keep the handset display current.
Call Transfer
nWhen an X-Mobile station indicates a flash during a call, it is treated as 
initiating a transfer operation. 
nThe operation is defined by DEFINITY® system’s standard operation for 
transfer from an analog phone.
NOTE:
Transfer is completed with an onhook button press.
Call Forward
nAn X-Mobile station is allowed to activate and deactivate call forwarding 
(all, busy, don’t answer) just as if it were a directly connected station. 
nThe remote station state is used to determine if call-forwarding criteria are 
met.
nIf the remote station is busy, then busy criteria is met. 
nIf the remote station does not answer the call, RNA criteria is met.
Te r m i n a l  Ty p e
nSetting the type in the station screen to XMOBILE will identify an X-Mobile 
station. 
Calling Capabilities
nAdministration of an X-Mobile station allows an administrator to customize 
call options, based on the parameters for an analog station.
DTMF Generation
nWhen an X-Mobile station is on a call, and INFO messages are received 
indicating KeyPad numeric button pushes, DTMF is generated on the call.
NOTE:
Digits are stimulated as CP_DIGITS to the Callp, which eventually are 
translated to ESIG_EXDs and invoke gm_esig to generate DTMF tone.
