nAttendant Control of Trunk Group Access
Calls will not route over a trunk with Attendant Control of Trunk Group 
Access set.
nAuthorization Codes
Authorization Codes must not be required for interflow routing. The FRL 
assigned to the VDN should be high enough so that the route desired for 
routing interflow c alls c an b e used without requiring an Authorization Code 
entry. If a route choice is encountered that requires a higher FRL, the 
interflow is considered an invalid d estination (rejected for Look Ahead 
Interflow or not available for standard interflow) without the a p plication of 
recall dial tone. Vector processing will continue.
nAAR 
ISDN-PRI facilities used to provide Look Ahead Interflow to a VDN on 
another switch in the customer’s network can use the AAR feature if 
private facilities are to be used for call routing.
nARS 
ISDN-PRI facilities used to provide Look Ahead Interflow to a VDN on 
another switch in the customer’s network can use the ARS feature for call 
routing.
nACD 
Look Ahead Interflow calls can b e interflowed directly to ACD splits on 
remote switches which d o not have Call Vectoring or Look Ahead Interflow 
enabled. In this case, the calls will be accepted or denied by generic call 
processing, even though full look ahead functionality will be lost. For 
example, an ACD split with a full q ueue would result in the call being 
rejected.
nCall Vectorin g
Call vectoring is required at the sending switch and the receiving switch.
Call vectoring operates d ifferently if Look Ahead Interflow is enabled at the 
sending switch. If ISDN-PRI facilities are successfully seized for a route-to 
operation, vector processing does not terminate until the call is accepted 
at the receiving switch.
A forced disconnect at the receiving switch will not cause the originator’s 
call to be dropped, but will only result in the failure of the Look Ahead 
Interflow attempt.
nCAS 
A centralized attendant can be a Look Ahead Interflow destination. 
						

							Feature Descriptions

nDID 
The Look Ahead Interflow routing over ISDN-PRI facilities can enter the 
receiving switch on a ‘‘DID’’ basis. That is, a destination extension address 
(a VDN) is included in the ISDN SETUP m e s sa g e  in the  Called Number 
information element.
nLook Ahead EAS Interflow o perates as described in this section for EAS 
and non-EAS environments.
nFRL and TCMs
The FRL for interflow over ARS/AAR route choices is assigned to the 
original VDN used for the incoming call.
nIncoming Call Management
The adjunct routing capabilities of vectoring can be used at the sending 
switch to determine if a call should be interflowed. Adjunct routing at the 
receiving switch can be used to tandem the call to a far-end switch.
nIS D N - PR I
ISDN-PRI connectivity end-to-end over a private network is required for 
Look Ahead Interflow.
nIntercept Treatment
No interc ept treatment should b e applied toward the c aller as p art of Look 
Ahead Interflow operation unless it results from a tandem connection on a 
non-Look Ahead Interflow basis. If the Look Ahead Interflow results in an 
intercept condition, the interflow should be rejected as part of the interflow 
vector programming, with alternate treatment provid e d at the sending 
switch.
nCDR (Sending Switc h )
No Ineffective Call Attempt or Outgoing Call CDR records will be 
generated for Call Vectoring route-to commands that are unsuccessful 
including denied Look Ahead Interflow attempts.
If a local (on-switch) call to a VDN generates a Look Ahead Interflow call 
attempt that is accepted, and answer supervision is returned from the 
receiving switch, then one Outgoing Call CDR record is generated with 
the originating extension as the calling number.
If an incoming (off-switch) call to a VDN g enerates a Look Ahead Interflow 
call attempt that is accepted, and no answer supervision is returned from 
the receiving switch, then one incoming CDR record will be generated.  
The VDN is the called number, and the duration is from the time answer 
supervision was provided to the incoming trunk.
If an incoming (off-switch) call to a VDN g enerates a Look Ahead Interflow 
call attempt that is accepted, and answer supervision is returned from the 
receiving switch, then two incoming CDR records will be generated: 
						

							Look Ahead Interflow
Issue  3   March 1996
3-859
1. An incoming record with the VDN as the called number and the 
duration as the time since answer supervision was provided to the 
incoming trunk.
2. An outgoing record containing the incoming trunk information as 
the calling number and the dialed d i gits and the outgoing trunk 
information as the called number.
The sending of a Look Ahead Interflow information element is counted 
toward Message Associated User-to-User Information (MA-UUI) counts.
nCDR (Receiving  Switch)
On the receiving switch, an incoming Look Ahead Interflow call is treated 
like any other incoming vector call as far as CDR is concerned. An 
incoming CDR record is recorded on all calls which return answer 
supervision.  The duration of the call is the time since answer supervision 
was returned.
If answer supervision is returned by the vector (via an announcement, 
collect, disconnect, or wait with music command), and the call 
is never terminated to another destination, then the VDN extension is 
recorded as the called number in the CDR record.
If the call terminates to a hunt group, then the VDN, hunt group, or agent 
extension is record ed as the called number.  If the ‘‘Record VDN in 
Record’’ option of the Feature Related System Parameters is ad ministered 
as ‘‘y,’’ then the VDN extension will override the ‘‘Call to Hunt Group - 
Record’’ administration option for Vector Calls.
If the call terminates to a trunk (tandem), then two CDR records will be 
generated:
1. An incoming record with the VDN as the called number and the 
duration as the time since answer supervision was provided to the 
incoming trunk.
2. An outgoing record containing the incoming trunk information as 
the calling number and the dialed d i gits and the outgoing trunk 
information as the called number.
nTrunk-to-Trunk Transfer
Interflowed calls may be transferred by a receiving switch agent to 
another trunk connection.

Administration
For full functionality, this feature requires the ISDN-PRI, Call Vectoring and Look 
Ahead Interflow o ptions to be enabled at both the sending and receiving 
switches.
Private network ISDN implementations require Private Network access software 
in the sending and receiving switches. If the destination number is specified as a 
10-digit public number, then ARS software could be used; otherwise, Private 
Network access software would be required.
Call Vectoring and ISDN-PRI (Integrated Services Digital Network (ISDN) — 
Primary Rate Interface) must be a dministered as described in their separate 
feature d esc riptions discussed elsewhere in this chapter.
Hardware and Software Requirements
Existing ISDN-PRI hardware can be used for ISDN connectivity to the receiving 
switch. No new hardware is required. Interconnecting facilities must b e ISDN-PRI 
with no interworking for the full c a pabilities of the feature to be o perational. Look 
Ahead Interflow calls which interwork may interflow successfully but the ability to 
do so on an intelligent b asis will be lost as will the Look Ahead Interflow DNIS 
information.
The ISDN-PRI, ETN (PNA), DCS or UDP, Call Vectoring, and Look Ahead 
Interflow features must be activated on both the sending and  receiving switches. 
As indicated above, PNA or ARS will be required for call routing. 
						

							Loudspeaker Paging Access
Issue  3   March 1996
3-861
Loudspeaker Paging Access
Feature Availability
This feature is available with all Generic 3 releases.
Description
Provides attendants and voice terminal users dial access to voice p aging 
equipment.
As many as nine individual p a ging zones can be provided by the system. (A 
zone is the location of the loudspeakers, for example, conference rooms, 
warehouses, or storerooms.)  In addition, one zone can be provided by the 
system to activate all zones simultaneously.
Each of the 10 zones provided by the system is assigned an individual trunk 
access code. The trunk access codes are used to activate Loudspeaker Paging 
Access. A  user can activate Loudspeaker Paging Access by dialing the trunk 
access code of the desired paging zone.  In addition, the trunk access codes 
can be stored in Abbreviated Dialing lists.  This allows multiappearance voice 
terminals to activate the feature via Ab breviated Dialing buttons.  Attendants can 
use a Direct Trunk Group select button to activate Loudspeaker Paging Access, 
if the desired  paging zone’s trunk access code is assigned to one of the buttons.
Once a user has activated Loudspeaker Paging Access for the desired zone, the 
user can speak into the handset and make the announcement.
In a ddition to, or instead of the system loudspeaker paging equipment, a 
PagePac  paging system can be used. A PagePac p aging system has a distinct 
advantage over the switch p aging system in that a PagePac system requires only 
one port on one circ uit pac k to provide as many as 39 paging zones. The switch 
p a ging system requires a separate port for each paging zone with a maximum of 
nine zones. Three different PagePac paging systems are available for use:
nPagePac 20
This is the smallest PagePac system.  The basic system provides a single 
p a ging zone with an input source for music over the pa ging system. The 
music can also serve as the music for the Music-on-Hold Access feature. 
Ad d itional add-on hardware is available to provide multizone paging for 3, 
9, or 39 p a ging zones.
nPagePac VS
This system provides 1 to 3 paging zones. It also permits the paging of all 
zones simultaneously. Ad ditional hardware is available to provide music 
and/or talkb ack over the p a ging system. 
						

							Feature Descriptions
3-862Issue  3   March 1996 
nPagePac 50/100/200
This system provides up to 24 p aging zones. Ad d itional hardware is 
available to provide music and/or talkb ack over the paging system.
PagePac equipment is also easy to use. A user simply dials the extension 
number (PagePac 50/100/200 only) or trunk access code assigned to the 
PagePac system. This connects the user to the PagePac equipment. If there is 
only one p a ging zone, the user then uses the handset of the voice terminal to 
p a ge someone.  If there are multiple zones, the user, after hearing a steady tone, 
dials a one- or two-digit code to access the desired zone(s) before p a ging.
Considerations
With Loudspeaker Paging Access, a user can b e paged at any location with 
loudspeaker paging equipment.  This feature is particularly useful when used in 
conjunction with the Call Park feature.  When a user is away from his or her 
location and receives a call, an incoming call can be answered and parked by 
another user.  The called party can then be paged and told what extension 
number the call is parked on.  The called party can then answer the parked call 
from a nearby voice terminal.
The system can have up to nine individual zones plus one zone to activate all 
zones simultaneously. A PagePac p a ging system can be used to provide up to 
39 paging zones.
An LDN or DID call cannot be connected to the paging facility.  However, the 
attendant can make the page and park the incoming call using the Call Park 
feature.
Interactions
The following features cannot be used with Loudspeaker Pa ging:
nAttendant Conference
nTerminal Conference
nData Call Setu p
nHold
nRingback Queuin g
nTransfer
Normally, a call to a busy single-line voice terminal results in a call waiting tone 
being heard by the called voice terminal user.  If that user is in the process of 
p a ging, the call waiting tone is not heard.
It is not p ossible to use a PagePac  p aging system for Code Calling Access when 
multizone paging is desired. The PagePac systems expect a two-digit code to  
						

							Loudspeaker Paging Access
Issue  3   March 1996
3-863
access a particular zone. The system, however, immediately plays the chime 
code once a connection is esta blished.
Administration
Loudspeaker Paging Access is administered by the System Manager.  The 
following items require administration:
nThe “ Deluxe Paging” and “Call Park Timeout to Originator” field on the 
Feature Related System Parameters screen must be a dministered as no.
nLoudspeaker Paging Access buttons are assigned through the Attendant 
Direct Trunk  Group  Selection, Ab breviated Dialing, and Facility Busy 
Indication features.
nTrunk access codes and Class of Restriction (per zone provid e d).
nPaging expiration interval.
nCDR activation.
If a PagePac p a ging system is to be used, it must be assigned a trunk access 
code or extension number (PagePac 50/100/200 only).
If a PagePac p a ging system is accessed through a CO or analog trunk, 
administration is not d one through the “Loudspeaker Paging Access”  form. 
Instead, the line is accessed as a standard trunk (trunk access code of a CO) or 
a standard extension (dialed extension that connects to PagePac).
Hardware and Software Requirements
Requires loudspeaker paging equipment and one port on a TN763 Auxiliary 
Trunk circuit pack (TN763D supports A-law) for each individual zone.  Paging 
interface equipment, consisting of a 278A adapter and a 24 volt power supply, is 
also required for each individual zone.  (This hardware can be shared with the 
Code Calling Access feature.  Each feature is activated by the assigned trunk 
access code.) A TN417 is also required in Italy, the United Kingdom, and 
Australia.
If Pa gePac  e quipment is used, one p ort on a TN747 CO Trunk circuit pack, 
TN742 (TN746B supports A-law), TN769, or TN746B, Analog Line circuit pack, or 
TN763 Auxiliary Trunk circuit pack (TN763D supports A-law) is required 
(depending on which PagePac system is used).
No a d ditional software is required.

Loudspeaker Paging Access — Deluxe
Feature Availability
This feature is available with all Generic 3 releases.
Description
Provides attendants and voice terminal users with inte grated dial access to voice 
paging equipment and Call Park capabilities.
When Loudspeaker Paging Access — Deluxe (also called Deluxe Paging in the 
remainder of this description) is activated, the call is automatically parked. The 
Call Park feature d oes not have to be activated separately. This is c onsistent with 
the Code Calling  Access feature activation. In  addition to the automatic Call Park 
capability, Deluxe Paging also lets parked calls return to the parking user with 
special distinctive alerting upon expiration of the Call Park Time-out interval.
Deluxe Paging also provides the ‘‘Meet-Me Paging’’ and ‘‘Meet-Me 
Conferencing’’ functions.  With Meet-Me Paging, a user can simply activate 
Deluxe Paging, make the announcement for someone else to c all him or her back 
and hang up. When the paged party answers, he or she is connected to the 
p a ging party. With Meet-Me Conferencing, another party can easily be paged 
and added onto a conference call.
The customer has the option of having either normal Loudspeaker Paging 
Access (disc ussed elsewhere in this document) or Loudspeaker Paging A c cess 
— Deluxe (Deluxe Paging). This desc ription disc usses only Deluxe Paging.
Paging Zones
As many as nine individual p a ging zones can b e provided by the system.
(A zone is the location of the loudspeakers, for example, conference rooms, 
warehouses, or storerooms.)  In addition, one zone can be provided by the 
system to activate all zones simultaneously.
Each of the 10 zones provided by the system is assigned an individual trunk 
access code. The trunk access codes are used to activate Deluxe Paging. A  
user can activate Deluxe Paging by dialing the trunk access code of the desired 
p a ging zone.  In a d dition, the trunk access codes can be stored in Abbreviated 
Dialing lists.  This allows multiap p earance voice terminals to activate the feature 
via Ab breviated Dialing b uttons.  Attendants c an use a Direct Trunk Group select 
button to a ctivate Deluxe Paging, if the desired paging zone’s trunk access code 
is assigned to one of the buttons.

PagePac Paging
In a ddition to, or instead of the system loudspeaker paging equipment, a 
PagePac  paging system can be used. A PagePac p aging system has a distinct 
advantage over the switch p aging system in that a PagePac system requires only 
one port on one circ uit pac k to provide as many as 39 paging zones. The switch 
p a ging system requires a separate port for each paging zone with a maximum of 
nine zones. Three different PagePac paging systems are available for use:
nPagePac 20
This is the smallest PagePac system.  The basic system provides a single 
p a ging zone with an input source for music over the pa ging system. The 
music can also serve as the music for the Music-on-Hold Access feature. 
Ad d itional add-on hardware is available to provide multizone paging for 3, 
9, or 39 p a ging zones.
nPagePac VS
This system provides 1 to 3 paging zones. It also permits the paging of all 
zones simultaneously. Ad ditional hardware is available to provide music 
and/or talkb ack over the p a ging system.
nPagePac 50/100/200
This system provides up to 24 p aging zones. Ad d itional hardware is 
available to provide music and/or talkb ack over the paging system.
PagePac equipment is also easy to use. A user simply dials the extension 
number (PagePac 50/100/200 only) or trunk access code assigned to the 
PagePac system followed by the extension number where the call is to be 
parked. This connects the user to the PagePac e quipment. If there is only one 
p a ging zone, the user then uses the handset of the voice terminal to page 
someone.  If there are multiple zones, the user, after hearing a steady tone, dials 
a one- or two-digit code to access the desired zone(s) before paging.
Operations
User operations vary d e pending on the type of voice terminal the user has and 
whether or not the user is an attendant.  Therefore, the various user o perations 
are described separately for single-line voice terminals, multiap p earance voice 
terminals, and attendants.
Activation of Deluxe Paging by Single-Line 
Voice Terminal Users
1. Go off-hook to get dial tone.
If already on a call with another party, press the Re call button or flash the 
switchhook.  The other party is placed on hold and recall dial tone is 
heard.
2. Dial the trunk access code for the desired paging zone. (Dial tone is 
heard.) 
						

							Feature Descriptions
3-866Issue  3   March 1996 
3. Dial the extension number where the call is to be parked. (Confirmation 
tone is heard and the call is temporarily parked.)
To park the call on your own extension, dial a ‘‘#’’ instead of the extension 
number.
4. Make the announcement. (The loudspeaker paging timer starts.)
5. Press the Recall button before the administered loudspeaker paging 
timeout interval expires and go on-hook. (The p aging equipment is 
released, the parked call is now waiting to be answered, and the timer for 
the Call Park Time-out interval starts.)
If another party was on the call and was placed on hold in Step 1, that 
party and the p aging party are in conference, parked on the call, and 
connected to the  paged party when he or she answers the call. (This is 
known as Meet-Me Conferencing.)
If the loudspeaker paging time-out interval expires before the Recall 
button is pressed, the paging user receives confirmation tone, the paging 
equipment is released, the call is automatically parked on your extension, 
and the calling party hears music (if provided). When the p ag e d party 
answers the call, he or she is connected to the paging party.  The paging 
party can then transfer the call to the calling party.
If the Call Park Time-out interval expires, the c all returns to the p aging user 
with the proper distinctive alerting (One-burst for internal calls and 
conference calls with both internal and external parties; Two-burst for 
external calls).  If unanswered, the call follows the coverage path of the 
p a ging user.
If no answer-b ack is required on the call, hang up instead of pressing the 
Recall button. The parked call is dropped and the paging equipment is 
released.
Activation of Deluxe Paging by Multi-Appearance Voice Terminal 
Users
1. Go off-hook to get dial tone.
If already on a call with another p arty, press the Transfer b utton.  The other 
party is placed on hold and dial tone is heard.
2. Dial the trunk access code for the desired paging zone. (Dial tone is 
heard.)
3. Dial the extension number where the call is to be parked. (Confirmation 
tone is heard and the call is temporarily parked.)
To park the call on your own extension, dial a ‘‘#’’ instead of the extension 
number.
4. Make the announcement. (The loudspeaker paging timer starts.)
