Call Progress Tones to Remote Party
nWhen a party dials to an X-Mobile station, the DEFINITY® system provides 
ring-back, busy, or re-order tone as appropriate. 
nIf the remote party is put on hold by the X-Mobile station, hold tone or 
music on hold is provided as administered for the system.
Call Waiting 
nWhen a call arrives for an X-Mobile station, and Call Waiting is 
administered, Call Waiting Tone is applied, as defined by the DEFINITY® 
system’s operation for call waiting for analog phones.
Conference
nIf an X-Mobile station has initiated a second call by a previous flash 
operation and the third party has answered the second call, then a flash 
operation will conference all three parties. 
nAnother flash operation by the X-Mobile station will DROP the last added 
party. 
nA Disconnect indication from the X-Mobile station while on a conference 
will leave the remaining parties connected and idle the X-Mobile station. 
nThe operation is defined by DEFINITY®’s treatment for conference by an 
analog station.
NOTE:
Applies only to second (inquiry) calls originated by the X-Mobile, it 
does not apply to call waiting calls.
Call Park/Answer Back
nAn X-Mobile station is able to park its current call after a flash operation in 
the normal method by feature access code. 
nAn X-Mobile station is able to answer a parked call by using the Answer 
Back feature access code.
Call Shuttle
nIf administered, an X-Mobile station is alerted via call waiting tone when 
another incoming call arrives for it while the X-Mobile station is on a call. 
nThe X-Mobile station can accept the second call via a flash operation. 
— This will put the first party on soft hold.
nSubsequent flash operations will shuttle between the second and first 
parties. 
nA disconnect operation in this case, where a party is being soft held, results 
in clearing the current call, and recalling the X-Mobile station to attempt to 
reconnect the soft held party.

Display-based Message Waiting Indication
nAll text information sent to an X-Mobile station contains information 
indicating a message is waiting for it, if the station is marked as having a 
message waiting. 
nNoted by an MW at the end of the display line. 
nContent of the string is administerable.
NOTE:
The display IE is used to indicate message waiting indication and is 
sent anytime the display updates.
Distinctive Ringing
nAll calls presented to the X-Mobile station as internal calls use a numbering 
plan code of 0x30 (network specific) in the calling party IE. 
nFor external calls, the numbering plan code is one of the standard public 
numbering plan values.
nAs an example, 0x21 is national ISDN.
Send All Calls
nAble to activate send all calls for itself by feature access code.
Terminating Extension Groups 
nAllowed to be a member of a terminating extension group.
Hunt Group 
nAn X-Mobile station is allowed to be a member of a hunt group.
Coverage Answer Group 
nAn X-Mobile station is allowed to be a member of a coverage answer 
group.
Abbreviated Dial
nAn X-Mobile station is allowed to use its station abbreviated dial lists and 
system abbreviated dial lists.
Call Pickup
nAn X-Mobile station is allowed to be in a Call Pickup Group.

Process
Idle X-Mobile WT’s switch-hook icon flashes when message is waiting
nWhen a message is left for an X-Mobile Station either through a messaging 
adjunct (for example, INTUITY™ AUDIX®) or one of the DEFINITY® 
system-based features (for example, Leave Word Calling), the X-Mobile 
WT’s message status indication is updated immediately. 
nIf the X-Mobile WT is idle, the switch-hook icon flashes. 
nIf the X-Mobile WT is offhook on a call, then the switch-hook icon starts 
flashing immediately after it goes onhook. 
nThe DEFINITY® system sends an MWI Activation message to the 
corresponding DAS whenever there is a change in the number of 
messages waiting at the X-mobile station resulting in one or more 
messages waiting for the user. 
nDepending on the type of message server, the message may not be sent 
with every change in status unless it results in a change in the indicator to 
an on-state. 
nThe number of messages field in the MWI activation message is always set 
to 1 regardless of the number of messages. 
nThe MW status is stored locally on the X-Mobile WT. 
nIt starts flashing the switch-hook icon immediately after the station goes 
onhook. 
nThe MWI Activation message is sent to the control link that the DEFINITY® 
system received the last location registration indication from the X-Mobile 
WT. 
nThis should handle the configuration where more than one DAS are 
connected to the DEFINITY®.
nIdle X-Mobile WT’s switch-hook icon remains off when no message is 
waiting. 
nWhen a message is deleted from an X-Mobile Station resulting in no more 
message waiting for the station, the flashing switch-hook icon on the idle X-
Mobile WT is turned off immediately. If the X-Mobile WT is offhook on a 
call, the switch-hook icon will not flash after the station goes onhook. 
nDEFINITY® sends an MWI Deactivation message to the corresponding 
DAS whenever there is a change in the number of messages waiting at the 
X-mobile station resulting in no more messages waiting for the user. 
nDepending on the type of message server, the message may not be sent 
with every change in status unless it results in a change in the indicator to 
an off-state. 
nThe number of messages field in the MWI Deactivation message is always 
set to 0. 
nThe MW status is stored locally on the X-Mobile WT.

nIt will not flash the switch-hook icon after the station goes onhook.
nMWI operation follows ASN.1 specification in ETS 300 745-1.
nMWI Activation/Deactivation messages are conveyed through FACILITY 
messages.
nThe DEFINITY® system sends the MWI Activation/Deactivation messages 
in a connectionless mode through the ISDN FACILITY messages. 
— This type of message does not require an associated call. 
— Call reference value is always set to 0x00.
Interface supports immediate mode only
nThe DEFINITY® system supports the immediate mode MWI only.
nThe messages are sent immediately upon a change in the number of 
message waiting at the X-mobile station. 
nDepending on the type of message server, the message may not be sent 
with every change in status unless it results in a change in the indicator 
state. 
nDoes not retransmit the MWI status during a call origination. 
nThe deferred or combined modes are not supported.
nThe DEFINITY® system refreshes MWI status during location registration.
nUpon successful location registration, the X-Mobile WT’s MW status is 
refreshed. 
nWhile idle, its switch-hook icon starts flashing if one or more messages are 
waiting at the station. 
nAfter successful location registration with the X-Mobile WT, the DAS sends 
a location registration indication message to the DEFINITY® system. 
nUpon receipt of the message, the DEFINITY® system sends an MWI 
Activation or Deactivation message back to the DAS depending if message 
is waiting at the WT.
Memory Impact of Capacity Changes
nThe X-Mobile capability is administered on the station admin screen. 
nThere is a moderate user manager memory impact.

nThe display is the same as a standard analog station with one exception. 
nWhen the station is onhook, the port field is blank. 
nWhen the station is offhook the port field contains the identity of the 
connected ISDN trunk port.
DEFINITY® refreshes MWI hourly
nThe DEFINITY® system runs an hourly MWI refresh (also known as audit) 
on a time available basis. 
nIt limits the refresh rate to no more than 6 MWI messages per second. 
nThe foreground traffic is assumed to be negligible as the refresh is run at a 
time available basis. 
nAt this rate, the DEFINITY® system does not overload the DAS’s worst 
case MWI message handling capacity of 6 MWI messages per second.
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 feature is enabled.
nThe X-Mobile station is treated as an analog station in terms of feature 
interactions except as noted in previous requirements.
Call Detail Recording
nA Call origination from an X-Mobile WT appears in the CDR as a call 
origination from the X-Mobile station.
nA Call Termination to an X-Mobile WT appears as a call termination to the 
X-Mobile 
Performance Impact
nThere is a minimum impact on performance (similar to a BRI call). 
nWhen a new call is originated from a trunk group marked as allowing X-
mobility, it is analyzed to check if the origination is from an X-Mobile station. 
— If it is, the origination is treated as a local station origination. 
— The check yields the UID of the X-Mobile station if successful, the 
additional processing is minimal.

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 was chosen, since most wireless terminals 
support only flash operations and are not multiappearance or context 
sensitive. 
nIn almost all cases, the operation expected for an X-Mobile station is 
identical to a similarly administered analog station. 
nAll flash (recall) operations behave identically to an analog station 
administered for flash answer back, including those that result in re-
origination. 
nIn case of far-end (forward) disconnect, an X-Mobile station is forced 
onhook; therefore, there is no possibility of re-origination or hearing of tone 
(busy or intercept) after a far-end drop, as happens when a wired analog 
station remains offhook.

Reset Shift Call
When a station call is made to a busy station, reset shift dial tone, called second 
dial tone by the Japanese PBX manufacturers, is heard. During reset shift dial 
tone, a single digit may be entered, which replaces the last digit of the originally 
dialed extension, and the call is offered to the new station. 
The length of the reset shift dial tone is administrable on a system basis and 
should have a range of 0-255. It is normally set to 10 seconds. Japanese PBXs 
can give this tone for up to 1 or 2 minutes before reverting to busy tone. If call 
coverage is supplied for the incoming number, the call goes to coverage as 
normal. If the coverage path is busy, the reset shift dial tone is heard and a single 
digit may be entered as described above. This feature is only active for station to 
station calls, not for incoming or outgoing calls. More specifically, the originator 
and destination of the call must both be stations connected to the DEFINITY
® 
system. In DCS or QSIG environments, both stations need not be connected to 
the same DEFINITY
® system, but must be on the same DCS or QSIG networks. 
Operation for transfer and conference is similar. If, while one is setting up a 
conference or transfer, the dialed party is busy, reset shift dial tone is heard and 
an opportunity is provided for a last digit reentry as on a normal call.
NOTE:
Multi-function analog terminal (MFAT) sets do not receive reset shift 
dial tone.
Performance Impact
This feature uses a port on a tone detector the entire time that a station is offhook 
and listening to reset shift dial tone. This means that whenever this feature is 
assigned, additional tone detector circuit packs may be needed. The number of 
additional tone detector circuit packs will vary depending on the following things:
nThe percentage of calls that encounter busy.
nThe average length of time that station set users will wait, listening to reset 
shift dial tone, before they dial a digit.
nThe administered maximum duration of reset shift dial tone.
Requirements
nTN2182 tone/clock circuit pack, any suffix or vintage, or
nTN780 tone/clock circuit pack, vintage 2 or later.

This feature applies to all hardware platforms.
NOTE:
Since Japan does not have regulations on the characteristics for reset 
shift dial tone, users require training to properly identify the tone that 
DEFINITY
® ECS uses for this feature. If the PBX is being used by 
people with limited dexterity, the timer associated with this feature is 
set to a large value, to give such users enough time to press the extra 
digit.
Call Processing
Reset shift feature operation
Play reset shift dial tone on busy calls if:
nA station or attendant originates a call, and
nThe dialed endpoint is in the dial plan and is one of the following types:
1. Station extension (extension)
2. Prefixed  extension (p extension)
3. AAR (aar)
nThe destination uses out-of-band signaling — either CCMS or ISDN trunk 
signaling — to signal “busy” back to the caller, then the calling set will 
receive reset shift dial tone.
Out of band signaling operation
Play reset shift dial tone on busy calls for non-ISDN trunks that use out of band 
busy signaling. This includes DCS trunks using out of band signaling such as X.25 
or TCP/IP. Subsequent reset shift dial attempts if a user receives reset shift dial 
tone, enters a single digit, and the resulting destination is busy, the calling set will 
receive reset shift dial tone again and restart the reset shift timer.
Turn off special dial
The PBX turns off reset shift dial tone when it receives a dialed digit from the 
station user. If a station user is listening to reset shift dial tone and the Reset Shift 
Timer expires, the station user receives busy tone.
NOTE:
The reset shift timer can be set to 0, in which case busy tone is sent 
instead of reset shift dial tone.
Maintain previous operation
When Reset Shift Timer field on systems parameter form is set to 0, operation will 
revert as if the Reset Shift Call Feature was not implemented.

Administration
Initial Administration
To administer the reset shift call feature on a DEFINITY® system where it was not 
previously used, the following procedure should be utilized:
1. In order to fully use the reset shift call feature, station extensions should be 
assigned with contiguous numbers for groups of users. Thus, users with 
similar job functions should have extensions that differ by only the last digit.
2. Set the Reset Shift Timer (seconds): field on the system parameters form 
to a value other than 0. The value entered in the Reset Shift Timer 
(seconds): field is the number of seconds that reset shift dial tone will be 
audible before busy tone is heard.
Removing Administration
To disable the reset shift call feature on a DEFINITY® system where it is active, 
set the Reset Shift Timer (seconds): field in the system parameters form to 0.
Timer administration
The system parameters features form has a new field for setting the reset shift call 
timer. The new field is called Reset Shift Timer (seconds). The timer will have a 
range between 0-255.
On an upgrade from a previous release to R8, the Reset Shift Timer field defaults 
to 0, disabling the feature.
The Reset Shift Timer (seconds): field is on the feature related system parameters 
form. It specifies the number of seconds that a station user can listen to reset shift 
dial tone and have the opportunity to launch a new call by pressing a single digit.

NOTE:
Japan does not have national regulations covering the cadence, 
frequency, or level of the reset shift dial tone. However, the de-facto 
standard is to mimic Japanese PBX operations.
Reset shift dial tone frequency
The reset shift dial tone has a frequency of 400 Hz ± ±± ±20 Hz. This requirement 
is based on the Fujitsu switch documentation for center frequency, and the 
acceptable range is based on the NTT ranges 3 specified for the public network.
Reset shift dial tone cadence
The reset shift dial tone has a repetitive cadence of 100 (± ±± ± 20%) milliseconds 
of silence, followed by 150 (± ±± ± 20%) milliseconds of tone, followed by 100 (± 
±± ± 20%) milliseconds of silence, followed by 650 (± ±± ± 20%) milliseconds of 
tone.
This requirement is based on the Fujitsu switch documentation for cadence, and 
the acceptable range is based on NTT specification for the public network.
Reset shift dial tone level
The reset shift dial tone has the same level as the currently implemented 
Japanese dial tone ± ±± ±2dBm. The range for this requirement is also obtained 
from the NTT Tone board support.
The reset shift dial tone is provided by systems equipped with either the TN780 or 
the TN2182B circuit packs.
