1197 Bridged Call Appearance 
20
nPriority Calling
The primary telephone user or the bridging user can make a priority call. If 
a priority call is made to an idle telephone, the primary telephone and all 
bridging users are alerted by priority alerting. 
A user cannot use an abbreviated dialing FAC after using a priority calling 
FA C .
nPrivacy-Manual Exclusion
Exclusion prevents any other user from bridging onto the call. Activation 
of exclusion by any user (primary or bridged appearance) before placing a 
call, prevents any other user from bridging onto the call. Activation of 
exclusion by any user active on a call, while the primary user and/or any 
other bridging users are active on the call, drops all other users from the 
call (including the primary user), leaving only the activator and the 
calling/called party on the call.
nRedirection Notification (multiappearance telephones only)
Redirection Notification is not provided at telephones with a bridged 
appearance of a primary extension number unless Ringing — Abbreviated 
and Delayed is administered to give notification.
nRingback Queuing
Ringback Queuing is not provided on calls originated from a bridged call 
appearance. However, after the principal user of the bridged extension has 
activated Ringback Queueing, the resulting callback call alerts at bridged 
appearances as well as at the principal user’s telephone. The call can be 
answered from the primary user’s telephone or from any bridged 
appearance.
nRinger Cutoff (multiappearance telephones only)
Ringer Cutoff prevents any nonpriority (or nonintercom) incoming call 
from ringing at that telephone. This is independent of whether the call is to 
the telephone’s primary extension or to any of the bridged appearance’s’ 
extensions.
nRinging — Abbreviated and Delayed
See Ringing — Abbreviated and Delayed, for other bridged appearance 
alerting options.

1198 Bridged Call Appearance 
20
nService Observing
The telephone user or bridging user can bridge onto a service observed call 
at any time. If the telephone is being service observed and an incoming call 
is answered by the bridging user, the call is not observed unless or until the 
telephone user bridges onto the call. Conversely, if the bridging user is 
being service observed and an incoming call is answered by the telephone 
user, the call is not observed unless or until the bridging user bridges onto 
the call.
If the bridging user activates Service Observing using a bridged 
appearance, Service Observing is activated for the bridging user.
nTerminating Extension Group
TEG calls to the primary extension do not ring at the associated bridged 
appearances. TEG calls cannot be answered or bridged onto from a bridged 
appearance of the TEG member’s primary extension. The primary 
telephone should not be assigned to a TEG.
nTransfer
— Single-line telephones
A call cannot be transferred by an analog telephone if more than one 
user is active on that call.
The primary telephone user, when no other bridges are active on the 
call, can transfer the call using normal single-line transfer 
procedures. Any attempt by a bridging user to bridge onto this call 
during a successful transfer attempt is denied (a standard denial 
response is returned to the bridged appearance).
An analog bridging user, alone on a bridged call, can transfer the 
call, using normal transfer procedures. Any attempt by the primary 
telephone user to bridge onto this call during a successful transfer 
attempt is ignored; and any attempt to bridge on by a bridging user 
is denied.
If the bridging user has no other available bridged appearances of 
the primary extension (other than the one he or she is currently on), 
the bridging user, after pressing the conference/transfer button, must 
select a call appearance to be used for the transfer, before dialing the 
number.

1199 Busy Indicator 
20
nMultiappearance telephones
If the bridging user has at least one available bridged appearance of the 
primary extension (other than the one he or she is currently on), the system 
automatically selects a bridged call appearance for the transfer when the 
conference/transfer button is pressed.
You can administer the system to automatically select the first idle 
appearance if there is no idle appearance with an extension matching the 
extension that is transferring the call.
If the primary user and the bridged user are both on the call when one user 
transfers the call, the user performing the transfer becomes the controlling 
user for the participation of both users on the conference. The controlling 
user is immediately dropped from the call. When the noncontrolling user 
hangs up, the appearance goes on soft hold. In this case, one of two things 
must occur to disassociate the appearance from the call: all other parties on 
the call hang up, or the controlling user rejoins the call and hangs up again.
nVideophone 2500 (single-line telephones)
A user may not use an analog bridge to a Videophone 2500 principal that is 
on a video call.
nVoice Message Retrieval
A voice message to the primary extension can be retrieved on a bridged 
appearance by the bridged appearance user. If a security code is required to 
retrieve the message, the bridging user must use the security code of the 
primary telephone.
nVoice Paging
The use of Voice Paging automatically invokes exclusion. Therefore, 
interactions for this feature are the same as for Privacy-Manual Exclusion.
Busy Indicator
The Busy Indicator button provides multiappearance telephone users and 
attendants with a visual indicator of the busy or idle status of one of the following 
system resources:
nAn extension number 
nA trunk group
nA terminating extension group 
nA hunt group—either direct department calling (DDC) or uniform call 
distribution (UCD)
nAny loudspeaker paging zone, including all zones

1200 Busy Verification 
20
The Busy Indicator button provides the attendant or user with direct access to the 
extension number, trunk group, or paging zone.
You can assign extension numbers, trunk group access codes, and Loudspeaker 
Paging access codes to a Busy Indicator button.
The Facility Busy lamp indication for a vector directory number (VDN) does not 
light when the VDN is being used. The associated button may be used to place a 
call to a VDN.
Busy Verification
Busy Verification (Verify button) allows attendants and specified multiappearance 
telephone users to make test calls to trunks, telephones, and hunt direct 
department calling (DDC) and uniform call distribution (UCD) groups. 
Attendants and multiappearance telephone users can distinguish between a 
telephone that is truly busy and one that only appears busy because of some 
trouble condition. They can also use this feature to quickly identify faulty trunks.
An attendant or multiappearance telephone user can activate Busy Verify by 
pressing the Verify button. If they want to verify a telephone or hunt group, they 
enter an extension number. If they want to verify a trunk, they dial a trunk-access 
code, followed by the 2- or 3-digit number of the trunk-group member to be 
verified. If the trunk-group member number is less than 10, the system requires a 
leading zero (01 or 001 rather than 1).
NOTE:
For DEFINITY ECS G3si or G3csi, the member number is a 2-digit 
number; for DEFINITY ECS G3r, the member number is a 3-digit number.
After an attendant or multiappearance telephone user has activated Busy 
Verification, the system checks the validity of the extension or trunk-access code 
and member number. If the number is not a telephone extension, DDC/ UCD 
group-extension, Automatic Call Distribution (ACD) split number, or trunk access 
code with a valid member number, the system denies Verify and returns intercept 
tone.
When you use Verify to check a valid telephone extension (one that is in the dial 
plan and assigned to a telephone), the system initiates a priority call to that 
extension. Ta b l e  1 4
 describes the process.

When you use Verify to check a valid ACD split, UCD group, or DDC group, the 
system initiates a priority call to that group. (Valid in this case means the split or 
group is translated and at lease one member is logged in.) Ta b l e  1 5

1203 Busy Verification 
20
Considerations
nA busy verification cannot be made to an analog extension that is waiting 
to be answered at another extension. A call must be answered before it can 
be verified.
nIf your country requires a tone other than 440 Hz, use the Intrusion feature 
rather than Verify to verify telephones.
nThe system does not provide bridging when you verify UCD and DDC 
groups or RLTs.
nYou cannot make outgoing test calls on DID trunks.
nYou can verify an extension that is administered without hardware 
(X-ported). In this case, the system generates reorder tone.
Interactions
nAutomatic Callback
Once the called party in an Automatic Callback call hangs up, neither 
extension can be busy-verified until both the calling and called parties are 
connected or the callback attempt is canceled (by the activating party or by 
time-out of the callback interval).
nCall Coverage
Since the busy-verification call to an extension is originated as a priority 
call, the call does not go to coverage.
nCall Forwarding
Busy verification made to an extension with call forwarding activated, does 
not busy verify the forwarded-to extension. Only the called extension is 
busy verified.
nCall Waiting Termination
You cannot verify an extension that called an active telephone and is 
receiving call-waiting ringback tone unless the extension has an idle call 
appearance.
nConference
The system denies busy verification of any extension involved in a 
conference call of more than five people. However, the system does allow a 
busy verification of any extension involved in a conference call of 5 or 
fewer parties. The system also denies busy verification of a trunk on a 
6-party call.

nData Privacy
Busy verification is denied if it would cause a bridging attempt on a 
telephone that has activated Data Privacy.
nData Restriction
The system denies Verify if Data Restriction is active on a call, and a busy 
verification bridging attempt is made on that call.
nHold
Busy verification of a multiappearance telephone is denied if all call 
appearances have calls on hold.
nIndividual Attendant Access
An attendant cannot make a busy verification of another individual 
attendant console or of the attendant group.
nLoudspeaker Paging Access
The system denies busy verification if the telephone or trunk to be verified 
is connected to paging equipment.
nTransfer
Once the originator of busy verification has bridged onto a call, any 
attempt to transfer the call is denied until the originator drops from the call.
ntelephone Origination Restriction
A telephone that is origination restricted can be assigned a Busy Verify 
button. However, the button cannot be used.
ntelephone Termination Restriction
The system denies busy verification of telephones that are termination 
restricted.

1205 Call Charge Information 
20
Call Charge Information
DEFINITY ECS provides two ways to know the approximate charge for calls 
made on outgoing trunks:
nAdvice of Charge — for ISDN trunks
Advice of Charge (AOC) collects charge information from the public 
network for each outgoing call. Charge advice is a number representing the 
cost of a call; it is recorded as either a charging or currency unit.
nPeriodic Pulse Metering — for non-ISDN trunks
Periodic Pulse Metering (PPM) accumulates pulses transmitted from the 
public network at periodic intervals during an outgoing trunk call. At the 
end of the call, the number of pulses collected is the basis for determining 
charges.
Call-charge information helps you to account for the cost of outgoing calls 
without waiting for the next bill from your network provider. This is especially 
important in countries where telephone bills are not itemized. You can also use 
this information to let employees know the cost of their phone calls, and so 
encourage them to help manage the company’s telecommunications expenses. 
Note, however, that you cannot necessarily use this information to dispute 
telephone bills with the network provider.
You need to request either AOC or PPM service from your network provider. In 
some areas, your choice may be limited. Your Lucent Technologies representative 
can help you determine the type of service you need.
NOTE:
This service is not offered by the public network in some countries, 
including the US.
Detailed description
The availability of AOC and PPM varies from one country to the next. In some 
countries, AOC information is received automatically for each call. In others, the 
system must request AOC information for each call.
In some countries, the public network sends call-charge information only at the 
end of a call. In others, the public network sends information during a call as well. 
PPM is available over the following trunk types:
nCO
nDIOD
nFX
nPCOL
nWAT S

1206 Call Charge Information 
20
CDR Output
The ISDN Call Charge or PPM field contains the last cumulative charge received 
from the network. If Call Splitting or Attendant Call Recording is enabled, and a 
call has been transferred for the first time, the ISDN Call Charge field contains the 
cumulative charge most recently received from the network. 
For all subsequent transfers, the ISDN Call Charge field contains the difference 
between the cumulative charge most recently received and the value generated in 
the previous CDR record for the same call.
A zero appears in the Call Charge field when: no AOC information is received; a 
value of zero is the last charge information received; or the outgoing trunk group 
is not administered for AOC or PPM.
Charge Display and CDR
DEFINITY ECS provides two ways for you to view call-charge information: on a 
display or as part of the Call Detail Recording (CDR) report. 
From a display, you can see the cost of an outgoing call, both while the call is in 
progress and at the end of the call. If you want end users to control when they 
view this information, you can assign a display button that they can press to see 
the current call charges. If you want call charges to display automatically 
whenever a user places an outgoing call, you can set the Automatic Charge 
Display field to 
y on the user’s Class of Restriction (COR) screen.
You can administer the system so that call charges appear on CDR reports. You 
can also allow users to view call charges on phone displays. For information on 
how to set this up, see ‘‘
Viewing call charge information’’ on page 463. 
Considerations
The Primary (or Secondary) Output Format for the CDR report must be one of the 
following types.
nCustomized — You must also include either the ISDN-CC or PPM fields in 
your record design. If you use both types of call-charge information, you 
need both fields.
nExpanded (Enhanced 24-word standard ASCII)
nInt-direct
nInt-ISDN (International ISDN expanded)
nInt-process 
nUnformatted (Enhanced 24-word standard ASCII)
nIf you want call charges to restart at 0 for calls that are forwarded or 
transferred, administer Outg Trk Call Splitting.
