Users with multi-appearance phones
The following description only applies to systems with deluxe paging. To page 
and park an active call simultaneously, users with a multi-appearance phone press 
Transfer, dial the trunk access code + an extension number where the call will be 
parked, make the announcement, and press Transfer again. The paged party dials 
the answer back feature access code + the extension number and is connected 
directly to the parked call. If the paging user ends the page by pressing Conference 
instead of Transfer, they are conferenced with the parked caller and both are 
connected in a 3-way conference with the paged user when he or she responds. 
This is called “Meet-Me Conferencing.”
If the paging user doesn’t want to park the active call, deluxe paging also allows 
“Meet-Me Paging.” Paging users can put an active call on hold and make their 
page, announcing their own extension. When the paged party calls, the paging 
user can conference the call on hold or transfer it to the paged party.
Users with single-line phones
This description only applies to systems with deluxe paging. To page and park an 
active call simultaneously, users with a single-line phone press Recall or flash the 
switch hook, dial the trunk access code + an extension where the call will be 
parked, and press Recall again. The paging user is conferenced with the parked 
caller and both are connected in a 3-way conference with the paged user when he 
or she responds. In other words, Meet-Me conferencing is standard operation for 
users with single-line phones. The paged party dials the answer back feature 
access code + the extension number and is connected directly to the parked call.
If the paging user does not press Recall until the loudspeaker paging time-out 
interval expires, they hear confirmation tone and the active call is automatically 
parked on their extension. When the paged party answers the call, they are 
connected to the paging party who can then transfer the call to the calling party.
How users place chime pages
Users page by dialing the trunk access code for a zone followed by the extension 
of the person they want to page. The system matches the extension dialed to its 
assigned code and plays the code over the loudspeakers. If users have an active 
call when they start to page, the call is automatically parked on the extension 
dialed in the page. Paged parties may retrieve the parked call normally.
Auxiliary paging systems
DEFINITY ECS requires a separate port for each paging zone and supports a 
maximum of 9 zones. If you have more than 9 zones or don’t want to allot that 
many ports for paging, Lucent can provide auxiliary paging systems. These

systems can support many zones from 1 port. They can also provide additional 
capabilities such as two-way communication through the loudspeaker system (the 
person paged can speak directly to the pager over the loudspeaker).
For more information, contact your Lucent Technologies representative.
Restrictions on loudspeaker paging
These restrictions apply to both voice, deluxe voice, and chime paging:
nA paging call can’t be placed on hold, included in a conference call, or 
transferred. Ringback queuing doesn’t work with loudspeaker paging calls 
either.
nUsers with any of the following restrictions cannot page:
— Controlled restriction
— Manual originating line service
— Origination restriction
— Miscellaneous trunk restriction
nA user with a single-line phone will not hear a call-waiting tone if they get 
a call while they’re paging.
nListed directory number and direct inward dialing calls cannot access the 
paging system. However, attendants can park incoming calls and page.
nRemote users (such as remote access users and tie-trunk users) who are 
paging cannot use # to park calls on their own extensions.
Interactions
nBridged Call Appearance
If a parked call includes a shared terminating extension group, a shared 
PCOL, or a redirected call with a temporary bridged appearance, the 
maximum number of off-hook parties on the call is five, instead of six. The 
sixth position is reserved for the answer-back call.
nCall Coverage
If a coverage call is parked by deluxe paging, the temporary bridged 
appearance at the principal extension is maintained as long as the covering 
user remains off-hook or places the call on hold.

nCall Park
If a call is parked by deluxe paging and the time-out interval expires, the 
call normally returns to the paging user. However, with remote access and 
tie trunk access, the call returns to the attendant. If unanswered, the call 
follows the coverage path of the paging user.
nCall Pickup
If you use call pickup or directed call pickup to answer a call and then park 
it by deluxe paging, a temporary bridged appearance at the principal 
extension is maintained if you remain off-hook or place the call on hold.
nConference — Attendant and Terminal 
Paging calls cannot be conferenced.
nData Call Setup
If the Data button has been pressed for modem pooling, access to paging is 
denied.
nData Privacy
If a call has Data Privacy activated and you park it by deluxe paging, Data 
Privacy for that call is automatically deactivated.
nHunt Groups
If a hunt-group member parks a call using deluxe paging, the call is parked 
on the member’s own extension, not the hunt-group extension. You cannot 
park calls on a group extension by dialing the extension as a call-park 
destination.
nNight Service
If a night-station user parks a Night Service call with deluxe paging, the 
call is parked on the night station’s primary extension.
nPersonal Central Office Line
If a PCOL call is parked by deluxe paging, the temporary bridged 
appearance of the call is maintained at the PCOL extension until the call is 
disconnected.
nTerminating Extension Group
If a TEG member parks a call using deluxe paging, the call is parked on the 
member’s extension, not the group extension. You cannot park calls on a 
group extension by dialing the extension as a call-park destination.
nTransfer
Paging calls can’t be transferred.

Chime paging
nAbbreviated Dialing
Don’t use special characters in abbreviated dialing lists used with chime 
paging.
nConference — Attendant
A call cannot be conference while the attendant is accessing paging 
equipment. The attendant can, however, release the call after paging the 
called party.
nConference — Te r m i n a l
A call cannot be conferenced while the user is accessing paging equipment.
nPagePac Paging Systems
If you use chime code paging with a PagePac system, you can only page 
one zone at a time. PagePac systems expect a 2-digit code to access a 
particular zone. The system, however, immediately plays the chime code 
once a connection is established.
nTransfer
A call cannot be transferred while the attendant is accessing paging 
equipment.

1421 Malicious Call Trace 
20
Malicious Call Trace
Malicious Call Trace (MCT) allows you to trace malicious calls. MCT allows you 
to define a group of telephone users who can notify others in the group when they 
receive a malicious call. These users then can retrieve information related to the 
call. Using this information, you can identify the malicious call source or provide 
information to personnel at an adjacent switch to complete the trace. MCT also 
allows you to record the malicious call.
You allow users in the group to activate MCT and/or to control malicious call 
trace. The controlling telephone user, or controller, receives the information that 
MCT collects on the call.
MCT Voice Recorder
The MCT Voice Recorder is any type of audio recorder (for example, a standard 
audio cassette player) that you can control via the DEFINITY Auxiliary Trunk 
board. 
To record the call, manually place the MCT Voice Recorder in Record mode. The 
telephone user then activates the MCT feature which applies power to the recorder 
(via the connected Auxiliary Trunk’s control signal interface).
Activating MCT 
To activate MCT while on an active malicious call, perform one of the following:
nPush an MCT-Activate feature button
nPlace the call on hold, get a second call appearance, and dial an 
MCT-Activate Feature Access Code (FAC). After the dial tone, the user 
then dials their own extension, presses
 #, or waits for a 10-second time-out.
nSignal another user in the defined group to activate MCT. The co-worker 
activates MCT, waits for the dial tone, and dials the call recipient’s 
extension.
nInform a controller, who can request that another switch continue tracing 
the call. 
The switches must be tandemed. The controller on the first switch supplies 
the trunk member port id to be traced. The controller on the second switch 
activates MCT and presses 
*, followed by the trunk port id. The letters A 
through E of a port id are entered as 1 through 5 on the station keypad. For 
example, trunk port id 01C0401 would be entered as 0130401.

1422 Malicious Call Trace 
20
Once MCT is activated, information on the call is collected and alerts users in the 
group. The alert is not a call, so it is not affected by queues at the user’s terminal. 
If an MCT Voice Recorder is connected, it begins recording the conversation.
NOTE:
Any Bridging, Conference, or Intrusion tone connected to parties on the 
connection are temporarily removed while the MCT Voice Recorder 
connects.
Controlling MCT 
The first controlling terminal to respond to an MCT alert becomes the controller 
for the call. Alerting on any other controlling terminals stops.
To begin trace of an incoming call using the Malicious Call Trace feature, the 
controller dials the 3-digit equipment location of the incoming trunk.
During alerting, the controller’s display shows the message “MALICIOUS CALL 
TRACE REQUEST.” While this message displays, no information on incoming 
calls displays.
When the controller pushes the MCT-Control button, information displays 
identifying the called party. When the controller pushes the button again the 
remaining MCT information displays.
MCT collects and displays three types of information, calling information as 
follows:
nIf the call originated inside the system or on the same node within a DCS 
network, the calling number displays. 
nIf the call originates outside the system and an ISDN calling number 
identification is available on the incoming trunk, then the calling number 
displays. Otherwise, the incoming trunk-equipment location displays. In 
this case, the user must call the connecting switch.
For all calls, the system displays the called number, the activating number, 
whether the call is active, and identification of any other parties on the call.
Deactivating MCT
The controller deactivates MCT by dialing the MCT-Deactivate FAC. 
Deactivation frees resources involved in the trace that were blocked. When all 
parties hang up, the MCT Voice Recorder disconnects.

Administering MCT for ISDN notification
The following describes how to administer the ISDN MCT notification for an 
ISDN trunk group (public-ntwrk, tandem, tie, or access).
Display the System-Parameter Customer-Options form and ensure that ISDN is 
enabled. 
One of the following must be set on the DS1 form:
nIf the DS1 is connected to the public network in Australia, set Country 
Protocol
 field to 2.
nFor a private network of DEFINITY systems, set Country Protocol to 1 
and 
Protocol Version to a. This is recommended if DCS features are 
used in the private network.
nFor a private network of DEFINITY systems, set Peer Protocol to 
q-sig. (Peer Protocol appears on the DS1 form when Signaling 
Mode
 field is isdn-pri, Connect field is pbx, and Interface field is 
peer-master or peer-slave.)
One of the following must be set on the ISDN-BRI Trunk Circuit Pack form:
nIf the ISDN-BRI is connected to the public network in Australia, set 
Country Protocol field to 2.
nFor a private network of DEFINITY systems, set Interface to 
peer-master or peer-slave.
Considerations
nTrunks involved in MCT are blocked from dropping to facilitate tracing. 
Telephones involved in a malicious call are not blocked from dropping.
nExcept for Emergency Access to the Attendant, features that normally 
display information do not do so on a controlling telephone. Otherwise, 
these features function normally until MCT deactivates.
nDo not use FACs to activate MCT because the process takes users too long.
nVisually Impaired Attendant Service (VIAS) voices-out display 
information for MCT activation, but not for MCT control.
nMCT information on an active malicious call is lost during a switch failure.
nWhen directing a trace to an adjacent switch, consider the following: 
— The malicious caller may hear a warning tone as a result of the 
intrusion.

Features and technical reference 
1424 Malicious Call Trace

— You may lose continuity on the trace because the person activating 
MCT on the second switch may not be the MCT controller.
nIf a malicious call comes in on a non-ISDN trunk, the controller needs the 
telephone number for the connecting switch and a cross-reference of 
system-trunk port numbers (including DS1 channel number, if appropriate) 
not the trunk equipment locations at the connecting switch. Be sure that 
they have this information.
nThe following are the system initiated operations for MCT:
— Conversation Recording — After the user activates MCT, the system 
attaches a MCT Voice Recorder, if available, to record the 
conversation, if available.
— Historical Recording — After the user activates MCT, the system 
records the MCT-information that you can subsequently retrieve via 
the MCT History report.
Interactions
nBridged Call Appearance
If a user at a primary extension receives an indication call, then a telephone 
with a bridged call appearance of this extension can bridge on to the call. 
For an MCT-Activate button push, if the currently active extension is a 
bridged appearance, the system records the primary extension as the MCT 
recipient.
For an MCT-Activate FAC, the user dials the number of the telephone with 
the bridged call appearance that is actually on the call, instead of the 
bridged number. However, the system logs the primary extension as the 
recipient. Likewise, for self-originated MCT activations via FAC, the 
system logs the primary extension as the MCT recipient provided that the 
recently held appearance is a bridged call appearance. When you activate 
MCT for yourself, dial # or wait for interdigit time-out.
nConference
A user can use conferencing to place a malicious caller on hold. The user 
can initiate conferencing and enter the MCT-Activate FAC, then stop 
conferencing and return to the malicious caller’s appearance.
MCT-Activate can be generated for a member of a conference and is not 
affected by the number of parties on the conference.
nCentralized Attendant Service
MCT-Activate, MCT-Control, and MCT-Deactivate must be performed by 
telephones within the same PBX.

nDCS
If a telephone in a DCS network is involved in a malicious call, the 
extension is recorded and displayed with the MCT information. MCT 
notification passes over ISDN-PRI DCS trunks but MCT-Activate, 
MCT-Control, and MCT-Deactivate must be performed by telephones 
within the same DCS node.
nEmergency Access to the Attendant
Ordinarily, during MCT-Control no other feature can access the controlling 
telephone’s display. However, MCT gives up control of the display until the 
Emergency Access call has completed.
nISDN
ISDN notification of an MCT activation takes place if either the originator 
of the call is an ISDN trunk group with Country Protocol 2 or any trunk on 
the call is an ISDN private network trunk with Country Protocol 1 and 
Protocol Version “a” or Peer Protocol q-sig. When the ISDN trunk group is 
Country Protocol 2, notification is sent only to the public network.
nMake-Busy/Position-Busy/Send All Calls
The switch attempts to activate Make-Busy or Position-Busy for telephones 
or consoles that activate MCT-Control. If a user has a Send All Calls (SAC) 
button administered, then SAC activates when the user activates 
MCT-Control. When MCT is deactivated, the telephone resets to its 
original state.
nMusic-On-Hold
If an agent places a malicious call on hold that is being recorded and the 
call goes to music-on-hold, the music-on-hold port and the MCT Voice 
Recorder port can lock. In this case, the MCT Voice Recorder continues to 
record the music-on-hold and is unavailable for recording subsequent 
malicious calls. You must perform a busy-out/release on the MCT Voice 
Recorder port to drop the connection.
nPriority Calling
A priority call to an MCT recipient is denied.
nQSIG Global Networking
MCT notification passes over the following ISDN QSIG trunk groups: 
tandem, tie, access, and DMI-BOS. QSIG supplementary services name 
and number ID provide a malicious caller’s name and telephone number.
nTransfer
If a user transfers a malicious call, the MCT information displayed on the 
controlling telephone identifies the transferring party as the MCT recipient.

1426 Messaging Server Interface 
20
A user transfers a malicious caller to hold. The user initiates a Transfer, 
receives the second dial tone, enters the MCT-Activate FAC, then halts the 
remainder of the Transfer operation and returns to the malicious caller’s 
appearance.
nTrunk Access Code
To activate MCT for a Trunk Access Code (TAC), a user must have an 
MCT-Control button administered. The user hears a dial tone and enters the 
trunk-member number for the trunk group that the TAC identified. The user 
then becomes the MCT controller for a call involving the identified trunk 
member. This TAC operation is useful when users need to trace a call that 
has tandemed through their switch to terminate on another switch.
nTrunk Groups
If a Personal Central Office Line (PCOL) is involved in an MCT, then the 
switch may hold up the trunk until the MCT deactivates.
Messaging Server Interface
NOTE:
This product is not supported as part of Lucent’s service support agreements 
for DEFINITY ECS R6 and later or DEFINITY BCS and Guestworks Issue 4 
and later. 
The Messaging Server (MS) interface provides MS-based features to the system 
such as Directory Service, Message Center Service, and Unified Messaging 
Services such as Electronic Documentation Communications, UNIX system mail, 
Office Telesystem, and DCS Centralized Messaging.
The MS interface consists of a control link between the DEFINITY ECS and the 
MS and includes a hunt group of MS agents that take messages. You must set a 
coverage point on the Coverage Path form to include the hunt group number of the 
MS agent hunt group.
The control link transmits extra information relevant to each MS agent-handled 
call for the following services:
nMessage Center Service — When agents receive (or drop) calls to leave or 
retrieve messages.
nLeave Word Calling — When users leave simple messages to call back or 
retrieve the call-back messages without MS agent intervention.
