Property Management System (PMS) Interfac e Issue 3 March 1996 3-977 — Active with PMS message exchange (act-pms) nControlled Restriction—one of two choices must be administered: — Active with no PMS message exchange (act-nopms) — Active with PMS message exchange (act-pms) nHousekeeping Status Information—one of two choices must be administered: — Active with no PMS message exchange (act-nopms) — Active with PMS message exchange (act-pms) If active is selected, the following additional administration is required: — The number of additional information (Housekeeper Identification) d i gits from zero to six that can be dialed. nExtension Numbers—assigned to the PMS Journal/Schedule printer and PMS log printer, if used, and to the PMS. Before an extension is assigned, the System Manager should chec k to make sure that the extension is not already assigned as a Call Detail Recording (CDR) or PSC extension. nSeconds Before PMS Link Idle Time-Out—s pecifies the number of seconds that the system will wait b efore it concludes that the PMS is not sending data across the transmission link. Choice is a numb er of seconds from 5 to 20. nMilliseconds Before PMS Link Acknowledgment Time-Out—sp ecifies the maximum time the system expects acknowledgment from the PMS that a message was received correctly. Choice is a number of milliseconds from 100 to 500. nPMS Link Maximum Retransmissions—sp ecifies the maximum number of times that the system will retransmit a message in response to a negative a cknowledgment or send an inquiry for an acknowledgment from the PMS for a message before giving up on the message transmission. Choice is a number from 1 to 5. nPMS Link Maximum Retransmission Requests—specifies the maximum number of times that the system will accept requests from the PMS to resend a reply (acknowledgment or negative acknowledgment) that the system did not receive b efore g iving up on the incoming message. Choice is a number from 1 to 5. nPMS Protocol—s pecifies the communication protocol mode used between the switch and the PMS. The choices are either normal or transparent.
Feature Descriptions 3-978Issue 3 March 1996 nDefault Coverage Path for Client Rooms—s pecifies the coverage path value that is set for an extension when the switch receives a ‘‘check-out’’ message while in the ‘‘transparent’’ communication protocol mode, or when a save translation is stored for extensions with a Client Room COS. The choice is a number from 1 to 600. nNumber of Digits in PMS Coverage Path—located on the second page of the “system-p arameter hospitality” form. The coverage path can be set to “3” or “4”. This is used to d etermine if the PMS adjunct software is using a 3- or 4-digit format for coverage path messaging. Hardware and Software Requirements A PMS, if used, can be connected through an MPDM and port on a Digital Line circuit pack or through an ADU and a port on a Data Line circuit pack. A DTDM (with a null mo dem), 7400A data mo dule, and 7400B data module can also b e used for the PMS link. Journal/Schedule and PMS log printers can be used and also require at least an MPDM and a p ort on a Digital Line circuit pack or an ADU and a port on a Data Line circuit pack. The Journal/Schedule and PMS log printer functionality can be on the same or two distinct printers. For G3r, there is no means for connecting directly to the switch processor circ uit pack, like with G3i. G3r requires, in a ddition to the data module to connect directly to the adjunct, a TN726B and a TN553 circuit pack combination.
Pull Transfer Issue 3 March 1996 3-979 Pull Transfer Feature Availability This feature is available with G3i-Global and all Generic V2 and later releases. Description NOTE: G3i-Global, G3V2, and later systems come with this feature turned off by default. Pull transfer is an enhancement of the standard transfer operation. Standard transfer allows voice terminal users to transfer trunk or internal calls to other voice terminals within the system without attendant assistance. The Pull Transfer feature allows either the calling or the called party (the party to whom the held party will be transferred) to comp lete the transfer operation. Analog telephone called parties who wish to p ull transfer the party that the controlling party has on hold should momentarily flash the switchhook (or press the Flash key or the Recall b utton). This comp letes the transfer of the held party to the called party. Digital telephone called parties who wish to p ull transfer the p arty that the controlling party has on hold should press the Transfer key. This com pletes the transfer of the held party to the called party. Please see the Transfer feature for a d escription of the regular (push) transfer feature. Considerations The pull transfer feature provides a convenient way to connect a party with someone better qualified to handle the call. Attendant assistance is not required and the call does not have to be redialed. If the attendant is the controlling party, any attempt to com plete a Pull Transfer operation by the called party is ignored. Pull Transfer cannot be c ompleted if the Attendant is the called party. A held party can only be transferred by the attendant with Push Transfer. Pull Transfer can only be completed if the calling party is a station on the same switch as the called party, or if the called party on another switch has been reached via an Italian TGU/TGE tie trunks.
Feature Descriptions 3-980Issue 3 March 1996 Interactions nAnalog Station Recall Operation and Feature Ac tivation: If the controlling party (with a party on hold) is talking with the called party, and either analog station recall or feature activation is initiated by the called party, the controlling party will not be put into the Hold for Transfer mo de but will be Pull Transferred. nDigital Station Transfer Operation: if the controlling party (with a party on hold) is talking with the called party and the transfer operation is initiated by the called party, the controlling party will not be p ut into the Hold for Transfer mode but will be Pull Transferred. nCDR: Checks will be made to ensure that calls are correctly recorded with CDR when a Pull Transfer o peration is com pleted. nNon-BRI Stations: If the “Pull Transfer” field on page 6 of the System Parameters Features form is set to “y,” the following could occur: Station A calls Station B, who answers, then presses the Transfer b utton and dials Station C. Station C answers and presses the Transfer button. The call from Station A is transferred to Station C. nBRI Stations: If the “Pull Transfer” field on page 6 of the System Parameters Features form is set to “y,” the following could occur: Station A calls Station B, who answers, then presses the Transfer b utton and dials Station C. Station C answers and presses the Transfer button to “ pull” the transfer. Instead, Station C goes off hook on another call appearance as if a new transfer is being originated. Administration The ‘‘System Feature’’ form is used to enable Pull Transfer. Hardware and Software Requirements No sp ecial hardware is required to implement the Pull Transfer feature in a standalone configuration. However, in a network environment, the TN497 TGU/TGE tie trunks are the only trunks that support the flash signalling necessary to comp lete the Pull Transfer operation between switches.
QSIG Global Networking Issue 3 March 1996 3-981 QSIG Global Networking Feature Availability This feature is available with Generic 3 Version 2 and later releases. Description QSIG Global Networking provides compliance to the International Organization for Standardization (ISO) ISDN-PRI private networking specifications. QSIG Global Networking Basic Call QSIG Global Networking Basic Call is available with G3V2 and later releases. The Basic Call complies with ISO standard 11572 for layer 3 to support private network connectivity. This means it provides the ISDN-PRI connection from PB X-t o - PB X. QSIG Global Networking Platform The QSIG Global Networking Platform, available in G3V3 and later releases, provides a private network protocol for the support of QSIG supplementary services. This p latform meets requirements for the ISO Private Network Generic Functional Procedures (Standard 11582) for Call-Related supplementary services. (Supplementary services are services provided by the PBX beyond voice or data connectivity and number transport and d isplay. Examples of supplementary services include Name Identification, Call Forwarding, and Transfer.) The QSIG Global Networking platform is based on Integrated Services Digital Network-Primary Rate Interface (ISDN-PRI) basic call setup protocol. It supports Call Relate d supplementary service transport, Abstract Syntax Notation 1 (ASN.1)/Basic Encoding Rules (BER), and Remote Operation Service Element (ROSE) services/protocols. QSIG is the generic name for a family of signaling protocols b ased on ITU-T (formerly CCITT) Q.931 a c cess protocols across the Q reference point. (The Q reference point or interface is the logical point where signaling is passed between two peer entities in a private network.) The QSIG signaling is used to provide PBX-to-PBX private networking in a multivendor environment. QSIG is being defined by the International Standard s Organization (ISO) to be the worldwide standard for PBX-to-PBX private networks. These standards are also supported b y the ISDN Private Networking Specification (IPNS) Forum, which is a consortium of PBX vendors working to esta blish worldwide standards for vendors to follow on a voluntary basis.
Feature Descriptions 3-982Issue 3 March 1996 The G3V3 release of QSIG Global Networking is a foundation for the QSIG supplementary services. It provides the Name Identification supplementary service, as defined by ISO Standards 13864, 13868, and 11572. G3V4 a d ds to the QSIG supplementary services b y providing for Call Forwarding as defined b y ISO Standards 13872 and 13873 and Call Transfer as defined by ISO Standards 13865 and 13869. DEFI NI TY s yst em G3V3 a n d later releases provide QSIG Global Networking in a d dition to some national protocols and the European Telecommunications Standards Institute (ETS I) protocols for supplementary services. The p rotocols are mutually exclusive. Users must specify on the “ ISDN-PRI Trunk Group” form which protocol they wish to use for ISDN-PRI supplementary services. Therefore, users who require the QSIG Global Networking Platform must a dminister it on the “ ISDN-PRI Trunk Group ” form. On this form, the national supplementary service protocols are defined as protocol ‘‘a’’, the QSIG Global Networking protocol is identified as protocol ‘‘b’’, and the ETSI Sup plementary Service protocol is identified as protocol “c”. Supplementary Services Identification Services The I dentification Services feature allows the PBX to send or receive the calling number, calling name, connected number, and connected name. Furthermore, it allows you to a dminister ‘‘yes,’’ ‘‘no,’’ or ‘‘restricted’’ for sending identification information. ‘‘Restricted’’ means that DEFINITY system sends the information but sends it ‘‘presentation restricted’’, which indicates to the receiving switch that the information should not be displayed. In the current release, a received restricted name or number is included on the Call Detail Record (CDR). Due to current networking limitations, a received Restricted Calling Party Number is d isplayed. However, a received restricted Connected Party Number or Calling/Connected Name is not d isplayed. The I dentification Services feature displays up to 15 characters for the calling/connected name and up to 15 digits for the calling/connected number across ISDN-PRI interfaces. When the DEFINITY system acts as a transit PBX (a PBX, other than the originating or terminating PBX, through which a call passes), it usually passes the name information as it receives the information. (A Transit PBX is defined as a PBX that routes an incoming call administered for Supplementary Services protocol “b” to a trunk also administered for Supplementary Services protocol ‘‘b.’’) However, in the case of tandemed calls, trunk g roup a dministration may override incoming tags, as long as d oing so does not lower the restriction on the information. For examp le, a tandemed call that comes in as restricted remains restricted even if the outgoing trunk is administered for ‘‘presentation restricted.’’ However, nonrestricted data is sent restricted if the trunk group administration is set for ‘‘presentation restricted.’’ The ability to send Calling Name, Connected Name, Connected Number, and Calling Number, or to send them restricted, is administered on the ‘ISDN-PRI
QSIG Global Networking Issue 3 March 1996 3-983 Trunk Group’ form. Also, the ‘ISDN Public-Unknown-Numbering’ and/or ‘ISDN Private-Numbering’ forms must be administered. The numbering form used to create the number is based on the ‘Numbering Format:’ field on the ‘isdn-pri Trunk Group’ form. If public or unknown is specified, the ‘ISDN Public-Unknown-Numbering’ form is used. If private is sp ecified, the ‘ISDN Private-Numbering’ form is used. Call Forwarding (Diversion) QSIG Call Forwarding is based on the DEFINITY system Call Forwarding All Calls and Call Forward Off Premise features. It extends the feature transparency aspects of Call Forwarding if there is a QSIG link between any of the PBXs involved. The feature is activated either by dialing a feature access code or by pressing a Call Forwarding button. See the Call Forwarding All Calls feature for a detailed description of how to use the Call Forwarding feature. QSIG Call Forwarding differs from other Call Forwarding features in that a d ditional call information is available to both the caller and the diverted-to terminal above what is provided if the call is forwarded over a link that is not administered for QSIG Supplementary Service protocol “b.” The originator (caller) of the call will see “forward” on their display. The diverted-to user will receive information that the call has been forwarded with the redirection symbol “f.” Depending upon QSIG Identification Services administration, the originator will see the connected party’s name or number followed by “forward.” The diverted-to user will see the originator’s identification (name or numb er) and the diverting user’s (called party) identification (name or numb er) followed by “f.” Up to 16 digits c an be stored as the forwarded-to number. A total of 20 digits can be sent at the time of forwarding (including the TAC or AAR/ARS access codes). When a call has already been forwarded three times, it will not be forwarded again but instead will terminate at the final forwarded-to terminal. Remote activation and deactivation are not su pp orte d. Because QSIG Call Forwarding is comp atible with the ISO QSIG standards, the DEFI NI TY s yst em ca n provide feature transparency for Call Forwarding with any PBX designed to these standards. Transfer QSIG Transfer is based on the current DEFI NIT Y syst em Transfer and Trunk-to-Trunk Transfer features. QSIG Transfer signalling will occur as long as one of the calls involves a QSIG link b etween the two PBXs. QSIG Transfer c onforms to ISO 13869 for QSIG Call Transfer By Join. This means that the transfer occurs through the switch where the transferring user resides and if the transfer involves two trunks, neither will be released after the transferring party is dropped from the call.
Feature Descriptions 3-984Issue 3 March 1996 The user activating the Transfer feature will see no difference between QSIG Transfer and the standard DEFINITY system Transfer or Trunk-to-Trunk Transfer features. See the Transfer feature and Trunk-to-Trunk Transfer feature descriptions for basic feature operation. QSIG Transfer d iffers from the standard DEFINITY system Transfer feature in that a d ditional call information is available for the connected parties after the transfer completes. However, the information is only sent on QSIG links, that is, if one c all is local to the transferring PBX, that user will not receive any new call information. Depending upon QSIG Identification Services administration, the connected parties’ disp lays will show each other’s name and/or numb er. If the name and number are not available, the display of a connected party is updated with the name of the trunk group involved. Interactions Identification Services Interactions nDistributed Communications Systems (DCS) There is no interworking for Calling/Connected Numb ers information or for Connected Name information in a DCS network. The Calling Name from a DCS network is received by the QSIG Global Network platform. However, the Calling Name is not sent by the QSIG Global Network platform to a DCS network. nNon-DCS Non-QSIG Global Networking ISDN-PRI Networks Calling/Connected Name and Number information may be sent to and from a non- DCS non-QSIG Global Network platform, d e pending on the protocol version (country protocol) for the interface. Call Forwarding (Diversion) Interactions All interactions that ap p ly to the standard DEFINITY Call Forwarding -- All Calls feature also a p ply to Call Forward ing with QSIG. See Call Forward ing All Calls on p age 3-396 for a description of these interactions. The following are a dditional interactions. nDistributed Communications Systems (DCS) nCall Forwarding feature transparency will not exist on calls tandemed between a QSIG (Sup plementary Service p rotocol B) network and a traditional DCS network. However, the basic call will continue. nForwarding and Coverage If the last c overage p oint in the coverage p ath is a number that routes over an ISDN PRI SSB trunk, the call will b e treated as a QSIG Diverting call.
QSIG Global Networking Issue 3 March 1996 3-985 nQSIG Identification Services Availability of name and/or num ber display at the originating and diverted-to users depends upon how QSIG Identification Services have been administered for the PBXs involved. nTerminating Call has Coverage Active If a call is forwarded off switch, the terminating switch has call coverage activated, and the criteria are met, the call does not route to the forward ing party’s coverage path, it routes to the terminating station’s coverage path. Transfer Interactions nDistributed Communications Systems (DCS) The only DCS transparency that will exist when a call is transferred in a DCS network and passed over a QSIG administered trunk is calling name. nQSIG Identification Services Availability of name and/or num ber display at the connected parties depends upon how QSIG Identification Services have been administered for the PBXs involved. Administration QSIG Global Networking and the Supplementary Services it provides require ISDN-PRI. Therefore, ISDN-PRI must be enabled on the “System-Parameter Customer-Options” form. On the ‘ISDN-PRI Trunk Group ’ form, the “ Supplementary Services Protocol” field must be administered to ‘‘b’’ to enable the QSIG sup plementary services protocols. See DEFINITY Communications System Generic 3 Version 4 Imp lementation, 555-230-655, or DEFI NI TY Com munications System Generic 3 V2/V3 Implementation , 555-230-653, for information about a dministering QSIG Name and Number Identification, Call Forwarding and Transfer. Hardware and Software Requirements QSIG Global Networking does not require any hardware or software b eyond what is required for normal ISDN-PRI connectivity. The TN767 circuit board is used for 24 channel applications and the TN464 with suffixes C and greater are used for both 24 channel and 32 channel applications. Users must have display-equipped voices terminals for displaying the call identification information.
Feature Descriptions 3-986Issue 3 March 1996 Queue Status Indications Feature Availability This feature is available with all Generic 3 releases. Description Provides indications of queue status for ACD calls based on the number of calls in queue and time in queue. These indications are provided via lamps assigned to the terminals or consoles of split agents or supervisors. In addition, an auxiliary warning lamp can be provided to track queue status based on the number of calls or time in queue. Also, display-equipped voice terminals and consoles can display the time in queue of a split’s oldest call and the number of calls in that split’s queue. Two types of Queue Status Indications are provided: nNumber of Queued Calls The Number of Queued Calls status indication is based on the total number of calls, excluding Direct Agent Calls (DACs), in queue at a split. DAC calls are not counted here, nor are they included in the count when checking whether a threshold warning should be given. The status indication can be provided by an Number of Queued Calls button with associated lamp on a voice terminal or console. Each split is assigned a Number of Queued Calls warning threshold. When this threshold is reached, the lamp associated with the Number of Queued Calls b utton flashes. If there are calls in the q ueue, b ut the threshold is not reached, the lamp lights steadily. If there are no calls in queue, the lamp goes dark. In a ddition to the Number of Queued Calls button(s), the Numb er of Queued Calls status indication can be provided b y an auxiliary queue warning lamp. This lamp can b e installed at any location c onvenient to the split agents. When the Number of Queued Calls warning threshold is reached, the auxiliary queue warning lamp lights steadily. nOldest Queued Time The Oldest Queued Time status indication is based on the time in queue of the oldest call in a split queue. The status indication can b e provided b y an Oldest Queued Time (Oldest Queued Time) button with associated lamp on a voice terminal or console. Each split is assigned an Oldest Queued Time warning threshold of 0 to 999 seconds. When the oldest c all in queue has been in queue for this length of time, the lamp associated with the Oldest Queued Time button flashes. If there are calls in the queue, but the threshold is not reached, the lamp lights steadily. If there are no calls in queue, the lamp goes dark.
