DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1297 Call-by-Call Service Selection 20 Figure Notes Using Country Protocol 1, you integrate services and features such as MEGACOM, ACCUNET, and INWATS onto a single ISDN-PRI trunk group with flexible assignment of trunks to each service or feature. Calls such as an incoming 800 Service call that requires through-switching as an Outgoing WATS call can be routed via the same facility. See the ISDN trunk group screen on page ‘‘ ISDN trunk group’’ on page 738 for a listing of available services. 1. DEFINITY ECS 2. Megacom trunk group 3. Megacom 800 trunk group 4. SDN trunk group 5.

Screens used to administer Call-by-Call Service Selection You administer Call-by-Call Service Selection on a per trunk group basis. The following list shows the required screens and the fields you must use on each screen: nSystem Parameters Customer-Options — Version — ISDN-PRI — ISDN-BRI Trunks — Usage Allocation Enhancements nISDN trunk group —Service Type — Usage Alloc — all fields on the Incoming Call Handling Treatment (ICHT) Table nRoute Pattern —IXC — Service/Feature —Band You can administer trunk Usage Allocation for multiple called numbers within a given Service/Feature, or you can administer trunk Usage Allocation for incoming or outgoing calls independent of Service/Feature. nSystem Parameters Customer-Options — Version — ISDN-PRI Trunks — ISDN-BRI Trunks — Usage Allocation Enhancements n Network-Facilities (Refer to the DEFINTY services documentation for information about the Network Facilities screen.) —All
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1299 Call-by-Call Service Selection 20 ISDN messages and information elements for usage allocation Understanding the technical details of ISDN messages and information elements may help you implement ISDN. Call-by-Call Service Selection allows the system to specify one of the preceding service types on a call-by-call basis. You can specify service types by classifying incoming calls to an ISDN Call-By-Call trunk group using the called-party’s number. You can also specify service types with a SETUP message that indicates the intent of the originating system to initiate a call using the specified service or facility. The SETUP message may contain units called information elements (IE) that specify call-related information. The IE used with Call-by-Call Service Selection are: nNetwork-Specific Facility (NSF) — Indicates which facilities or services are to be used to complete the call (typically not used outside the US and Canada). The system also checks all incoming ISDN trunk calls for the presence of an NSF IE. If an NSF IE is present, the system makes sure that the requested service is compatible with the trunk administration before it accepts a call. For an outgoing call on a Call-By-Call trunk group, the NSF IE is constructed using the Service/Feature specified on the routing-pattern preference selected for the call. If the Service/Feature specified does not have an associated NSF, an NSF IE is not sent. For example, SETUP messages for incoming and outgoing calls classified only by a called-party number do not contain an NSF IE. nTransit Network Selection — Indicates which interexchange carrier is to be used on an inter-LATA call. If a call requires both the Service/Feature and the interexchange carrier to be specified, the interexchange carrier information is sent in the NSF IE rather than the Transit Network Selection IE. Usage allocation plans Optional Usage Allocation Plans (UAP) may be assigned to provide more control over a Call-by-Call Service Selection trunk group. You can allocate a minimum and maximum number of channels for incoming and outgoing called numbers, privileged users, and voice and data calls.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1300 Call-by-Call Service Selection 20 A UAP allows the customer to set the following options: nMaximum number of trunks that each service can use at any given time.The sum for all services may exceed the total number of trunk-group members. For example, for a15-member trunk group, you could administer a maximum of seven MEGACOM service calls, six MEGACOM 800 service calls, and eight SDN calls. This ensures that all trunk-group members are not dominated by a specific service, yet allows for fluctuations in demand. nMinimum number of trunks that always must be available for each service. The sum for all services may not exceed the total number of trunk-group members. For example, for a 10-member trunk group that provides access to MEGACOM service, MEGACOM 800 service, and SDN, the minimum number of trunks to be used for each of these services cannot add up to more than 10. When these UAP limits are exceeded, the system rejects the call, even if a trunk is available. On outgoing calls, the calling party receives a reorder tone unless other preferences are available. You can assign either fixed or scheduled UAP for each Call-by-Call Service Selection trunk group. nWith a fixed UAP, one plan applies at all times. nWith a scheduled UAP, different plans can be administered to apply at different times of day and different days of the week. As many as 6 activation times and associated plans can be assigned for each day of the week. You can have anything from a simple fixed UAP to a very flexible UAP with many scheduling options. You can even start out with no UAP and build one as the need arises. Incoming call-handling treatment Call-by-Call Service Selection provides special incoming call-handling treatment for ISDN trunk groups. An incoming call on an ISDN trunk is handled according to a treatment table administered for the trunk group. Depending on the platform you use, the table allows for a different number of combinations of call treatments. The treatment for an incoming call is selected based on the first 3 columns in the ICHT table on the ISDN Trunk Group screen. When the attributes of an incoming call match these specifications, the call is treated according to the corresponding
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1301 Call-by-Call Service Selection 20 following 4 columns. If an incoming call matches more than one set of specifications, the most restrictive case applies. The following table lists the possible cases from most restrictive to least restrictive. Call detail recording On successful call attempts using ISDN Call-By-Call trunk groups, CDR records the NSF specified by the call’s NSF IE. CDR refers to this information as the ISDN Network Service (INS). The value passed to CDR is the 3-digit equivalent of NSF IE. NSF information for Facility Type 2 calls (used with ISDN-Pri Call-by-Call trunk groups) also is recorded if the NSF is available in the incoming SETUP message. If an outgoing Call-by-Call Service Selection call uses an interexchange carrier other than the presubscribed common carrier, CDR records the 3-digit or 4-digit Interexchange Carrier Code (IXC). CDR may not record the IXC properly if the dialed-code format differs from the US IXC formats. When a Call-by-Call Service Selection call is rejected because of a UAP, CDR records the cause as an ineffective call attempt. The NSF recording takes place also for the user-defined Facility Type 2. However, the NSF recording takes place only if the NSF is available in the incoming SETUP message.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1302 Calling Party/Billing Number 20 Interactions nMultiquest Flexible Billing Do not use a Service/Facility with the Facility Type field set to 2 or 3. NSF processing is not performed for Facility Type 2. An NSF is not included in the outgoing SETUP message for Facility Type 3. nTime-of-Day Routing Any Time-of-Day Routing administration that affects routing preference also affects Call-by-Call Service Selection. Use Time-of-Day Routing to vary the IXC based on the time of day and day of the week. Calling Party/Billing Number Calling Party Number/Billing Number (CPN/BN) allows the system to transmit CPN/BN information to an ISDN-PRI trunk group. The CPN is the calling party’s telephone number. BN is the calling party’s billing number. The CPN/BN may contain international country codes. CPN/BN is used with an adjunct application. Brief Description The following list shows the screens used to administer CPN/BN and the fields you must use on each screen: nISDN trunk group — All fields including Per Call CPN/BN nISDN Numbering — Public/ Unknown or ISDN Numbering — Private —All nProcessor Channel Assignment (Refer to the DEFINTY services documentation for information about this screen.) —All On the ISDN Trunk Group screen, assign all fields needed to provide an ISDN-PRI link between the system and the adjunct. Set the Per Call CPN/BN field to can-only, can-pref, bn-only, or bn-pref as required to make sure that CPN/BN information is sent with a call-offered event report to the adjunct. On the Processor Channel screen, assign all fields for one data link. The system can support only one interface.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1303 Calling Party Number Restriction 20 Related topics Refer to ‘‘ ISDN service’’ on page 1394 for an overview of ISDN capabilities. Refer to the DEFINITY ECS Guide to ACD Call Centers for information on using Calling Party Number and Billing Number with Automatic Call Distribution (ACD) and Inbound Call Management. Complete all screens required to administer ACD. Refer to the DEFINTY services documentation for information about the Multifrequency-Signaling-Related System parameters screen. Calling Party Number Restriction With Calling Party Number (CPN) Restriction, you can administer individual phones to restrict sending CPN information on outgoing calls (per call restriction). Also, phone users can use a phone button or a feature access code (FAC) to restrict CPN information on individual outgoing calls (per line restriction). CPN Restriction works on any trunk that supports MFC signaling. Per Line CPN Restriction overrides any outgoing trunk group CPN administration. Per Call CPN Restriction overrides any Per Line CPN Restriction for the phone, and it also overrides any Trunk Group administration for sending the calling number. For a tandemed ISDN call, only the Tandem Trunk Group’s “sending calling number” administration applies. Interactions CPN Restriction is not supported on: nlocal switch station-to-station calls ncalls originated from attendant console or data module nDCS calls (DCS CPN information is not affected by CPN Restriction) nUniform Dial Plan (UDP) calls nTrunk Access Code (TAC) calls where the Per Line CPN Restriction field on the * screen is y or r, or when the Per Call CPN Restriction FAC is dialed before the TAC nnon-ISDN calls that must be tandemed nPer Call CPN Restriction over Adjunct Switch Application Interface (ASAI) and CTI interfaces
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1304 Class of Restriction 20 Class of Restriction You use Class of Restriction (COR) to define the types of calls your users can place and receive. Your system may have only a single COR, a COR with no restrictions, or as many CORs as necessary to effect the desired restrictions. You will see the COR field in many different places throughout the DEFINITY System - when administering phones, trunks, agent logins, and data modules, to name a few. You must enter a COR on these screens, although you control the level of restriction the COR provides. You must administer a COR for the following objects: nAgent LoginID nAccess Endpoint nAnnouncements/Audio Sources nAttendant Console nAuthorization Code — COR Mapping nConsole-Parameters nHunt Groups nLoudspeaker Paging nData Modules nRemote Access (each barrier code has a COR) nStation nTerminating Extension Group nTrunk Groups nVector Directory Number Called-party and calling-party restrictions Called-party and calling-party restrictions are the basis for all CORs. When no restrictions are needed, assign a single COR with called-party and calling-party restrictions set to none. You can use this COR for unrestricted telephones, trunk groups, terminating extension groups, Uniform Call Distribution (UCD) groups, Direct Department Calling (DDC) groups, data modules, attendant groups, and individual attendant extensions. The called-party restriction is checked only at the called terminal, module, attendant console, zone, or group, even if a call redirects from one telephone to another. For example, if a called terminal (with no terminal restrictions) has Call Forwarding active to a restricted terminal, the call still completes.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1305 Class of Restriction 20 Inward restrictions You can use inward restrictions to permit users to receive only internal calls. Inward restrictions prohibit users at assigned telephones from receiving public-network, attendant-originated, and attendant-extended calls. The COR of the originally-called extension is the only one checked unless you administer 3-way COR check on conference and transfer calls. Denied calls are routed to intercept tone, a recorded announcement, or the attendant for Direct Inward Dialing (DID) calls. Manual terminating line restrictions You can use manual terminating line restrictions to allow users to receive calls only from an attendant or that were extended by an attendant. Calls can redirect to a manual terminating line-restricted telephone. The COR of the originally-called extension is the only one checked. Local CO, foreign exchange (FX), and Wide Area Telecommunications Service (WATS) calls are routed to the attendant. DID calls are routed to an announcement or the attendant. Telephone calls are routed to intercept treatment. Origination restrictions You can use origination restrictions to prohibit users from originating calls. These users can still receive calls. Outward restrictions You can use outward restrictions to prevent users from placing calls to the public network. These users can still place calls to other telephone users, to the attendant, and over tie trunks. If necessary, an attendant or an unrestricted telephone user can extend a call to an outside number for an outward-restricted telephone user. When outward restriction is applied to the Calling Party Restriction field on the Class of Restriction form, calls coming into a trunk with that COR will be denied if they make use of the AAR/ARS feature. Public restrictions Public restrictions prohibit users from receiving public-network calls. Denied calls are routed to an intercept tone, a recorded announcement, or the attendant. Public restrictions still allow users to receive internal calls from other telephones or calls that were extended from the attendant.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1306 Class of Restriction 20 Termination restrictions You can use termination restrictions to prohibit users from receiving any calls. These users can still originate calls. DID or Advanced Private-Line Termination calls route to a recorded announcement or the attendant. Fully restricted service Fully restricted service prevents specific users from making or receiving public-network calls. Fully-restricted users cannot use authorization codes to deactivate this feature. Calls from the public network to a fully-restricted extension redirect to intercept treatment or to the attendant. If the call redirects to the attendant, the attendant’s display indicates the call was redirected because of fully restricted service (FULL). There are circumstances where an extension with fully restricted service can access or be accessed by the public network. Miscellaneous terminal restrictions You can use miscellaneous terminal restrictions to prohibit users from accessing other specific terminals. Restricted calls are routed to intercept tone. Miscellaneous restriction groups apply on a per-COR basis. However, you can assign the same COR to more than one facility. Facilities with the same COR may be like facilities (such as two telephones) or different facilities (such as a telephone and a trunk group) Miscellaneous trunk restrictions You can use miscellaneous trunk restrictions to prohibit users from accessing specific trunk groups, such as WATS or CO trunk groups. Any or all trunk groups can be in a miscellaneous-trunk-restriction group. Restricted calls are routed to intercept tone. Toll and TAC-Toll restrictions Toll restrictions prevent users from placing public-network calls to certain toll-call numbers. Toll restriction is not a COR; you assign Toll restrictions to outgoing trunk groups on the Trunk Group form. You disable TAC-toll restrictions for specific outgoing trunk groups on the Trunk Group form.
