DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1447 Multiappearance Preselection and Preference 20 nIdle Appearance Preference When a user lifts the handset to place a call, the system automatically connects them to an idle appearance even if an incoming call is ringing at another appearance. The in-use (red) lamp tracks an idle appearance when the user lifts the handset. nLast Appearance Preference When a user lifts the handset, they connect to the call appearance or bridged appearance last used for a call, unless an audibly ringing call on a different appearance caused the line selection to move. If the line selection moves, a call may be originated, answered, or unheld, depending on the state of that appearance. nPreselection Before lifting the handset to place or answer a call, the user can press a call appearance button or a feature button to select an appearance when the in-use lamp is dark. Preselection reenters a held call or activates a feature or the speakerphone if the telephone is so equipped. Preselection overrides both Preference options. If the user does not lift the handset within 5 seconds after using Preselection, the selected appearance returns to idle. You can assign a preselection feature button. For example, if a user presses an Abbreviated Dialing button, a call appearance is automatically selected. If the user lifts the handset within 5 seconds, the system automatically places the call. Preference dictates whether a user connects to the ringing call appearance or to an idle call appearance. If there is no call, users automatically connect to an idle call appearance when they lift the handset, regardless of which Preference option is assigned. Considerations nMultiappearance telephones can have from 2 to 10 call appearances. One of these call appearances is reserved for placing calls or for receiving a Priority Calling call. If a telephone has 2 call appearances and one of them is active, a nonpriority call cannot access the other call appearance, even if the call appearance is idle. The default number of call appearances is 3. nThe reserved call appearance is not a fixed-position button; it is just the last-idle call appearance. For example, if a telephone has 10 call appearances, any 9 can be in use, but the tenth (last) is reserved.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1448 Multifrequency Signaling 20 Interactions nAutomatic Incoming Call Display Incoming calls are not displayed if Idle Appearance Preference is activated. nCall Coverage If you administer Cover All Calls as the redirection criterion for a telephone, administer Idle Appearance Preference for the telephone. The called party can then lift the handset without accidentally connecting to a call that should be screened. nIntegrated Services Digital Network — Basic Rate Interface When an ISDN-BRI telephone (with Select Last Used Appearance enabled) transfers a call while off-hook by using the handset, the user hears dial tone on the last-used call appearance. Users of other telephone types hear silence in this case. Related Topics For more information, refer to ‘‘ Station’’ on page 894. You administer this feature with the following two fields: nIdle Appearance Preference nSelect Last Used Appearance Multifrequency Signaling Multifrequency (MF) signaling is a form of address signaling used between switches and the central office (CO). It is similar to dual-tone multifrequency (DTMF) signaling in that tones convey the dialed number. With MF signaling, the signal is typically a combination of two frequencies from a group of 5 or 6 frequencies (2/5 or 2/6). The origination switch and destination switch exchange tones that have specific meanings according to the MF protocol. Detailed description DEFINITY ECS supports two frequency groups: nR2-multifrequency compelled signaling (R2-MFC) frequency nR1 frequency (for Spain and Russia)
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1449 Multifrequency Signaling 20 R2-MFC is a version of MFC recommended by the International Telecommunication Union (ITU). It provides signaling between a CO and a switch over analog or digital CO, Direct Inward Dialing (DID), or Direct Inward and Outward Dialing (DIOD) trunks. It also provides signaling between 2 DEFINITY switches. DEFINITY ECS provides MF signaling that complies with ITU regulations and national regulations for specific countries. It provides these types of MF signaling: Multifrequency Espana (MFE), MF Shuttle, and multifrequency compelled (R2-MFC). These protocols signal the called number, the calling party’s number (automatic number identification (ANI)), and information about the type of call or type of caller (category). DEFINITY ECS allows prefix digits for ANI sent on outgoing calls to be defined per PBX or per the originator’s class of restriction. If a call is a tandem call and the incoming and outgoing trunk use different protocols, the switch makes no attempt to convert between the various protocol’s meanings for category. Instead, nthe PBX uses the incoming trunk’s Class of Restriction (COR) assigned category if the outgoing trunk is Russian or R2-MFC, and nthe PBX uses ARS call types if the outgoing trunk is MFE. DEFINITY ECS provides the incoming ANI to all features on the switch that need to identify the calling party. MFE MFE, for Country code 11 (Spain), uses R1 frequency and compelled signaling. It is available on CO and DID trunk groups. There are four kinds of MFE signaling: nPublic 2/5 nPublic 2/6 nIbercom 2/5 nIbercom 2/6
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1450 Multifrequency Signaling 20 MF Shuttle MF shuttle signaling, for country code 15 (Russia), uses R1 frequency and noncompelled signaling. With MF shuttle signaling, it is possible to change to decadic rotary pulse in the middle of address signal exchange. MF shuttle signaling is available on CO, DID, and DIOD trunk groups. Also, automatic number identification (ANI) transmission, for Country code 15, uses a gapless R1 MF signal and is completed within 800ms. This is available on an outgoing CO trunk group. R2-MFC R2-MFC permits each country to define the meanings of the R2 frequency combinations. Specific frequency combinations for different countries are described in the DEFINITY ECS Application Notes for Type Approval. R2-MFC Considerations nBoth non-group II signaling and group II signaling are supported on incoming MF signaling calls. The group II signaling protocol has an extra signal that provides caller-category information. Only group II signaling is supported on outgoing MF signaling calls. nMF signaling also can be used in tandem trunk groups. After address signals are collected from an incoming group II MF signaling call, the call can route to a group II MF signaling trunk. nBoth incoming and outgoing MF signaling calls support ANI. The terminal displays ANI information and the Call Detail Recording (CDR) record records it. nWhen DEFINITY ECS uses an open numbering plan, the end-of-dial signal must be defined in the incoming Group I signal administration. After sending all address digits, the CO sends the end-of-dial signal to DEFINITY ECS. nIf DEFINITY ECS makes an outgoing call to the CO that uses an open numbering plan, the CO should send the signal A.1 to DEFINITY ECS after sending the last address digit to the CO. Then, the CO should timeout and send a pulsed signal A.3 to DEFINITY ECS requesting the Group II signal.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1451 Multifrequency Signaling 20 Guidelines for administering MF signaling To administer MF signaling, first you identify the origination switch and the destination switch. (The switch making the call is the origination switch; the switch answering the call is the destination switch.) nThe origination switch creates forward signals, classified as group I and group II signals. nThe destination switch creates backward signals, classified as group A and group B signals. Group I and group A signals comprise the basic signaling for the dialed number. More elaborate signaling requires Group II and group B signals. Signal meanings and timer values can be administered. The sequence below shows a typical interaction between the origination (forward group I and group II signals) and destination switch (backward group A and group B signals). Forward Backward Group I digit -->
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1452 Multifrequency Signaling 20 Second, you assign the correlation between signal codes and their meanings. 1. Assign a code to every message. The code consists of a group category, like group II or A, and a number. nFor example, you might assign code A.1 to the message “next-digit.” 2. Assign a signal to each identifying code. nIn every country, the frequencies (levels may differ by country) assigned to the identifying codes are the same. However, the messages assigned to the identifying codes may be different. For example, in Switzerland the B.6 code and its associated signal convey the free message, while in Thailand, free is conveyed by the B.1 code and its associated signal. But in both Switzerland and Thailand, the frequency associated with the B.1 code is the same. As another example, you might assign the signal “busy” to the B.1 code. To receive Russian incoming ANI: nOn the DID or DIOD trunk group screen, set the Country field to 15 and the Protocol Type field to inloc. nOn AAR and ARS Digit Analysis Table screen, set the ANI Rq field to y or on AAR and ARS Digit Conversion Table screen, set the ANI Req field to y. Interactions nASAI ANI collected from incoming R2-MFC signaling can be used with ASAI. nAbbreviated Dialing Although calls dialed automatically from an abbreviated dialing privileged list complete without class of restriction (COR) checking, ANI prefix and ANI truncation still apply. nAttendant Console If the attendant assists or extends a call for a station via Straightforward Outward Completion and Through Dialing, and if the attendant has not yet released the call when the request for ANI comes in from the far end, the attendant’s COR is used to select the ANI for the call. If the attendant has already released the call when the request for ANI comes in from the far end, the attendant’s COR is used to select the ANI for the call.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1453 Multifrequency Signaling 20 nAuthorization Codes The COR of the authorization code as administered on the authorization-code form is not used for ANI prefix determination, even if the originating endpoint enters an authorization code before call processing for an outgoing call seizes an outgoing trunk. If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk, the ANI for PBX is used. nBridging The ANI of a telephone’s primary extension also applies to calls originated from a bridged call appearance of that extension on another terminal. ANI prefix and ANI truncation will still apply to the primary extension number of bridged call appearances. nCall Detail Recording CDR records ANI collected from incoming MF signaling. For India MFC, on incoming calls, ANI digits may be appended with zeroes if the actual ANI digits are less than the administered ANI-length; in those cases, the zero-digits appear on CDR. nCall Redirection A call is redirected if any of the following are active: Call Forwarding, Call Coverage, Send All Calls, or Night Service. nCall Vectoring Call Vectoring can now use ANI collected from incoming MFC signaling. The ANI of a call vector is not used when a call vectoring route-to command routes a call over an outgoing trunk. Instead, the ANI of the originating party is sent. nDID No Answer Timer DID No Answer Timer is applied to MF signaling DID calls. nDistributed Communications System (DCS) In a DCS arrangement, the ANI sent to the CO is determined by the ANI for PBX on PBX_B, but the category sent to the CO is determined by the Category for MF ANI field on the Class of Restriction form for the incoming DCS trunk or by the type of call. nExpert Agent Select (EAS) For ANI, the EAS agent’s login extension number and COR overrides the extension number and COR of the physical terminal where the agent is logged in. ANI prefix and ANI truncation apply to logged in EAS agents.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1454 Multifrequency Signaling 20 nHunt Groups and Automatic Call Distribution (ACD) Splits For ANI, a physical terminal’s extension number and COR overrides the extension number and COR of the hunt group or ACD split that the terminal is a member of or logged into. ANI prefix and ANI truncation apply to terminals that are members of hunt groups or logged into ACD splits. nIntercept treatment For DID MF signaling calls that are denied, you can administer whether the corresponding B.x signal or intercept tone should be sent to the CO. The default is to send the administered DID/TIE/ISDN Intercept Treatment. If the option to send the B.x signal is set, then: — For Group II calls, the B.x signal for the intercept is sent to the CO. — For non-Group II calls, if the CO dials an invalid number, the trunk is locked (regardless of this option). If the CO dials a number that is valid but not assigned, intercept tone is sent to the CO. nMultimedia Call Handling (MMCH) For call origination, multimedia complexes use the COR assigned to their telephones. ANI prefix and ANI truncation will apply to the telephones assigned to multimedia complexes. nOff-Net Call Coverage or Call Forwarding If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk that can supply ANI, the ANI received from the incoming trunk is used. If the originating endpoint is neither of the above, the ANI for PBX is used. nPersonal Station Access (PSA) For ANI, the PSA extension number and COR overrides the extension number and COR of the physical terminal where the PSA extension number is associated. ANI prefix and ANI truncation will apply to associated PSA extension numbers. nRemote Access The COR of a remote access barrier code is not used for ANI prefix determination when the originating end point dials a remote access extension and then places a call. If the originating endpoint is an extension, the extension’s ANI is used. If the originating endpoint is an incoming trunk, the ANI for PBX is used.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1455 Multifrequency Signaling 20 nStation Set Displays When no ANI is possible, if station sets are equipped with display option, they do not display the ANI digits. Instead, the trunk group name displays. When ANI is possible, ANI displays on the station set. For India Only. If ANI digits are padded with “zero,” then zeroes also are displayed along with ANI digits. nTandem / Offnet Calls If ANI digits are received on incoming MFC calls, the ANI digits are sent to outgoing tandem/off-net calls. For Russia Only. The ANI is requested on incoming trunks only when all the address digits have been collected. When the incoming trunk on a tandem call is a Russian incoming local trunk administered to collect ANI, the PBX collects all ANI digits before seizing the outgoing tandem trunk. This happens even if ARS is administered with a “min” value low enough that it would be possible to determine an outgoing route through digit analysis. For India Only. On an outgoing tandem-call, the default operation is to send the ANI-Not-Available forward signal if ANI is not available from the incoming trunk. However, in order to support this operation, leave the ANI for PBX field blank, and define the ANI-Not-Available signal.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1456 Night Service 20 Night Service DEFINITY ECS provides the following Night Service features: nHunt Group Night Service nNight Console Service nNight Station Service nTrunk Answer from Any Station nTrunk Group Night Service Hunt Group Night Service Hunt Group Night Service allows an attendant or a split supervisor to assign a hunt group or split to Night Service mode. All calls for the hunt group then are redirected to the hunt group’s designated Night Service extension (NSE). When a user activates Hunt Group Night Service, the associated button lamp lights. Night Console Service Night Console Service directs all calls for primary and daytime attendant consoles to a night console. When a user activates Night Console Service, the Night Service button for each attendant lights and all attendant-seeking calls (and calls waiting) in the queue are directed to the night console. To activate and deactivate this feature, the attendant typically presses the Night button on the principal attendant console or designated console. Night Station Service Night Station Service directs incoming calls for the attendant to designated extensions. Attendants can activate Night Station Service by pressing the Night button on the principle console if there is not an active night console. If the night station is busy, calls (including emergency attendant calls) receive busy tone. They do not queue for the attendant. When Night Station Service is active, incoming calls to the attendant route as follows: nDID Listed Directory Number (LDN) calls route to a designated DID-LDN night extension. nInternal calls route to the DID-LDN night extension (unless you administer the system so only DID-LDN calls can route to the LDN night extension).
