Look Ahead Interflow Issue 3 March 1996 3-857 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 3-858Issue 3 March 1996 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.
Feature Descriptions 3-860Issue 3 March 1996 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.
Feature Descriptions 3-864Issue 3 March 1996 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.
Loudspeaker Paging Access — Deluxe Issue 3 March 1996 3-865 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.)
