DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1207 Call Charge Information 20 Attendant consoles Automatic Charge Display Mode does not apply to attendant consoles. The attendant must always press a button to enter display mode. Performance impact Call Charge Information can impact system performance in several ways. The information coming in over ISDN trunks takes up bandwidth, and reduces the maximum amount of traffic the ISDN D-channel can handle. This is especially true in countries such as Germany and France, where the network sends charging information updates as often as every 3 to 10 seconds for each active international call. The number of sets that display charge information and the frequency of updates also affect performance. Normally, the update frequency should match the average rate at which call charge updates are received from the public network. !CAUTION: Updating displays too frequently can cause unnecessary system performance degradation. If performance slows to an unacceptable rate, you may need to lengthen the amount of time between updates. Button operations If you administer a button for charge display, the display-set user can press the disp-chrg button at any time during the call to see the current charges. If your public network sends charge information only at the end of a call, display-set users must have this button and press it just before they hang up. After the call drops, the charge will appear. Other display functions If a user invokes the elapsed-timer display, the timer may overwrite part of the charge display. If the user has a local directory (Dir button), and presses this button while a call is in charge display mode, the call-charge information will overwrite the directory any time an update comes in. To avoid this, the user must press Exit or Normal.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1208 Call Charge Information 20 Interactions nAttendant Features Attendant consoles cannot have automatic charge display. If you want the attendant to see call charges, you must assign a disp-chrg button to the attendant console. If the attendant moves to transfer an outgoing call, the display returns to normal mode. If the transfer does not complete, or the call remains at the attendant console for whatever reason, the attendant must press the disp-chrg button again to view call charges. nAutomatic Incoming Call Display If a user has charges displayed for an existing call and a second call rings on another line appearance, the display returns to normal mode for a short time to show the identity of the caller. The user must press disp-chrg again to view call charges, or if automatic charge display is enabled, must wait for the Charge Update Frequency Timer to expire. nBridged Appearance If a user makes a call using a bridged appearance, the call charges display on the telephone from which the call is made. If that telephone has Automatic Charge Display as part of its COR, the charges will appear automatically. The actual charge for the call appears on the CDR report as if the call had been made from the principal’s extension, not the bridged appearance. nCall Coverage or Forwarding — Off Net Call charges for a call to an extension whose calls are redirected over a public-network trunk are charged to the called extension, not the calling extension. However, if the call is placed from an internal phone that has charge display capability, the caller will see the charges for the redirected call. nCall Park When a user parks a call, the display mode returns to Normal. If a user retrieves a parked, outgoing call from another display telephone, the display on that set shows the current call charges if the user presses a disp-chrg button, or if the user’s COR allows Automatic Charge Display. If call splitting is enabled, the display shows the charges accumulated since the user unparked the call.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1209 Call Charge Information 20 nCall Transfer For Advice of Charge, if a transferred call is routed over a public-network ISDN-PRI trunk group, AOC administration for the outgoing trunk group controls whether AOC information is requested or recorded for the call. If two or more outgoing trunks are connected together via trunk-to-trunk transfer, the DEFINITY ECS may receive AOC information from the network for each outgoing trunk involved in the call. nCDR Adjuncts DEFINITY ECS does not tandem AOC information through a private network to other switches. Therefore, the CDR adjunct that records AOC information must receive its input from DEFINITY ECS directly connected to the public network. nCDR Call Splitting If you use CDR Call Splitting for outgoing trunks, each time a call is transferred, the system generates a separate record. Attendant Call Recording, a form of Call Splitting, generates a CDR record when an attendant drops from a call. Incoming Trunk Call Splitting has no effect on charge information. If you rely on Call Splitting or Attendant Call Recording, you should request call charge information during the call. However, for AOC, this increases message activity on the signaling channel and reduces Busy Hour Call Capacity of the DEFINITY System. In some countries, or with specific protocols, AOC information during a call is not available. In this case, you can use the Elapsed Time in the CDR records to allocate the charges among the parties on the call. You must use CDR Call Splitting if you want the charge display to restart at 0 when a call is transferred. nCentralized Attendant Services In any configuration where a branch system has no direct connection to the public network, the private network does not pass call-charge information to these branches. nConference If a user adds a third party to a call in charge-display mode, the display returns to normal. Call charges will not appear as long as there are more than two parties on the call. nDistributed Communications System (DCS) In any configuration where a branch system has no direct connection to the public network, the private network does not pass call-charge information to these branches.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1210 Call Coverage 20 nElectronic Tandem Network (ETN) In any configuration where a branch system has no direct connection to the public network, the private network does not pass call-charge information to these branches. nHold If a user places a call on hold, the display returns to normal mode. The user must press disp-chrg again to view call charges, or if automatic charge display is enabled, must wait for the display to refresh. nLast Number Dialed Users can view the dialed number while active on a call by pressing the stored-numb button, then the last-numb button. To view call charges again, the user must then press the disp-chrg button, or (if Automatic Charge Display is part of the user’s COR) the Normal button. nQSIG In any configuration where a branch system has no direct connection to the public network, the private network does not pass call charge information to these branches. nSystem Resets If you perform a warm reset while calls are active with charge display, the charge display will freeze. To resume call charge updates, users must press the Normal button. Call Coverage Call Coverage provides automatic redirection of calls to alternate answering positions in a Call Coverage path. Call Coverage allows you to: nEstablish coverage paths with up to 6 alternate answering positions nEstablish redirection criteria that govern when a call redirects nRedirect calls to a local switch location nRedirect calls to a remote (off-net) location nRedirect calls based on time-of-day nAllow users to change back and forth between two coverage choices (either specific lead coverage paths or time-of-day tables). Refer to ‘‘ Extended User Administration of Redirected Calls’’ on page 1337 for more information.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1211 Call Coverage 20 Hardware requirement The Coverage of Calls Redirected Off-Net (CCRON) generally requires call classification hardware. Both the Call Classifier - Detector and Tone Clock/Call Classifier - Detector circuit packs provide tone detection ports including the capability to do call classification. There are 8 ports on each circuit pack. For countries using the USA tone plan, a Call Classifier - Detector or Tone Clock/Call Classifier - Detector circuit pack is sufficient to provide call classification. For countries not using the USA tone plan, the Call Classifier - Detector and Tone Clock with Call Classifier - Tone Detector circuit packs must be configured appropriately to provide call classification. The number of simultaneous monitored calls depends on the: ntotal amount of outbound call traffic, nnumber of call classification ports available, and nuse of other switch applications that make use of call classification ports. Coverage of Calls Redirected Off-Net competes with the following switch applications for ports on the Call Classifier - Detector and Tone Clock with Call Classifier - Tone Detector circuit packs: nAnswer Detection nCall Prompting nCallVisor ASAI nMulti-Frequency Compelled (MFC) signaling Serious degradation of switch performance, including the inability to launch new calls, can result from an insufficient resource of call classifier ports. Detailed description When a call meets the redirection criteria of the principal, the call attempts to route to one of up to 6 points in the coverage path. If no coverage points are available, the call may revert to the called principal or group. If any point in the path is available, the call either rings the individual phone or member of a group specified for that point or queues on the group. Once a call is ringing or queued at any point in a coverage path, the call never reverts to the called principal or group, or to the previous point. A call remains at a coverage point for the Coverage Subsequent Redirection interval. At the end of this interval, the call attempts to route to any remaining points in the coverage path. If no other point is available to accept the call, the call remains queued or continues ringing the current coverage point.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1212 Call Coverage 20 Call Classification Classifying a call means determining the state of the call at its final destination. That means whether the call was answered, received busy, reorder, intercept, special information tone (SIT), or other treatment. Call classification is accomplished by the ISDN protocol or ports on the: nTone Clock with Call Classifier - Tone Detector circuit pack nCall Classifier - Detector circuit pack Coverage Path A Call Coverage path is a list of up to six alternate answering positions (covering users/points) that are accessed, in sequence, when the called party or group is not available to answer the call. You can assign any of the following entities a coverage path so they are eligible to have calls redirected to coverage: nACD split nAgent LoginID nPCOL group nTEG nHunt group nPhone (on-net or off-net) You establish the coverage paths and set the redirection criteria. If a coverage path is not assigned to a particular facility, calls are not redirected from that facility, unless another feature is assigned. A coverage path can include any of the following: nAnnouncement nAttendant group nAUDIX nCoverage answer group nHunt group nPublic network number (off-net) nVector directory number (VDN) nPhone (on-net or off-net)
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1213 Call Coverage 20 DEFINITY ECS allows for multiple coverage paths. However, for any particular call only one coverage path is used. The “lead” coverage path is the first coverage path in a chain that is considered when a call redirects to coverage. The chain is defined in the Next Path Name field on the Coverage Path screen. When a call redirects to coverage, the lead coverage path at that time is checked to determine whether its coverage redirection criteria match the call status. If there is a match the lead coverage path is used. If the lead coverage path’s redirection criteria does not match, the system moves down the path chain until it finds a coverage path with redirection criteria that matches the call status. If the chain is exhausted before the system finds a match, the call does not redirect to coverage. Once a coverage path is selected, it is used exclusively through the duration of the call. You can assign lead coverage paths directly in the Coverage Path 1 or Coverage Path 2 fields on the appropriate screens. For example, to assign a lead path for a TEG, set the Coverage Path field on the Terminating Extension Group screen. You can also assign the lead paths indirectly by assigning a Time-of-Day Coverage Table to the Coverage Path 1 and Coverage Path 2 fields. Then, the system selects the lead path according to the time of day. Subsequent redirection interval The number of times a call rings at a particular coverage point before the switch moves the call to the next coverage point depends on the type of ringing coverage point (for example, local, Distributed Communications System (DCS), CCRON, and so forth). For each type of coverage point, the following table shows which subsequent redirection interval on the System-Parameters Call Coverage/Call Forwarding screen is used. nLocal — On the System-Parameters Coverage/Forwarding screen, the Local Subsequent Redirection/CFWD Don’t Answer Interval field. nOff-net — On the System-Parameters Coverage/Forwarding screen, the Offnet Subsequent Redirection/CFWD Don’t Answer Interval field. n* — The call is left off-net. Type of Coverage Subsequent Redirection Interval local local remote * CCRON off-net DCS local
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1214 Call Coverage 20 Call redirection criteria Redirection criteria determine the conditions under which a call redirects from the principal (called) extension to the first position in the coverage path. The criteria and conditions that apply are as follows: nActive Redirects calls to coverage immediately when the principal is active on at least one call appearance. For a phone with only one appearance or a single-line extension, assign the Busy criterion (discussed below) instead of the Active criterion. nBusy Redirects calls to coverage when all available call appearances at the principal extension are in use. For multiappearance phones, one call appearance can be reserved for outgoing calls or incoming priority calls (discussed later). The remaining assigned call appearances are available for other incoming calls. An incoming call (other than a priority call) redirects to coverage only when all of these unreserved call appearances are in use. If at least one unreserved call appearance is idle at the principal extension, the call remains at that idle appearance. A Terminating Extension Group (TEG) is considered busy if any phone in the group is active on a call. Each phone in a UCD or DDC group must be active on at least one call appearance for the call to redirect to coverage. If any phone in the group is idle the call directs to that phone. If no phone is available, the call can queue if queuing is provided. If queuing is not provided, then the call routes to coverage. If the queue is full or all agents are in an auxiliary state, the group is considered busy and the call routes to coverage. Queued calls remain in queue for the Don’t Answer Interval. A call will not cover to a hunt group if no agents are logged in, or if all agents are in AuxWork mode. nDon’t Answer Redirects calls to coverage if unanswered during the assigned Don’t Answer Interval. A call rings for the Don’t Answer Interval and then redirects to coverage. nCover All Calls Redirects all incoming calls to coverage. This criterion has precedence over any other criterion previously assigned.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1215 Call Coverage 20 nSend All Calls/Go to Cover Allows users to activate Send All Calls or Go to Cover as an overriding coverage criteria. This redirection criteria must be assigned before a user can activate Send All Calls or Go to Cover (discussed later). nNo Coverage Occurs when none of the above criteria are assigned. Calls redirect to coverage only when the principal has activated Send All Calls or the caller has activated Go to Cover. Both of these overriding criteria are discussed later. Redirection criteria can be assigned in combinations. For example, you can combine Active/Don’t Answer and Busy/Don’t Answer. Other combinations are not possible or do not provide any useful function. For example, Active/Busy does not accomplish anything. A busy phone is always active. Redirection criteria are assigned separately for internal and external calls. By linking the coverage paths, Busy/Don’t Answer can be assigned for internal calls and Active can be assigned for external calls. Similarly, Busy/Don’t Answer can apply for external calls and No Coverage can apply for internal calls. In the latter case, internal calls remain directed to the called phone or group. All calls extended by the attendant are treated as external. Warning users if their calls are redirected You can warn analog phone users if they have features active that may redirect calls. For example, if the user has activated send all calls or call forwarding, you can administer a setting to play a special dial tone when the user goes off-hook. See ‘‘ Special Dial Tone’’ on page 669 for more information. Features that override Call Coverage Some system features override Call Coverage criteria; they are checked before the redirection criteria are checked. These features are: nCall Forwarding All Calls Call Forwarding provides a temporary override of the redirection criteria, if Send All Calls is not active. The call attempts to complete to the forwarded-to extension before redirecting to coverage. If the principal’s redirection criteria are met at the forwarded-to extension, the call redirects to the principal’s coverage path.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Features and technical reference 1216 Call Coverage 20 nGo to Cover Go to Cover allows users, when calling to another internal extension, to send the call directly to coverage. This is optionally assigned to a button on a phone and is activated by the internal calling party. Use of Go to Cover is discussed later. nSend All Calls Send All Calls allows principals to temporarily direct all incoming calls to coverage regardless of the assigned redirection criteria. For example, if the redirection criteria are administered so that no calls redirect, all incoming calls terminate at the principal’s phone unless Send All Calls is activated. Also, Send All Calls allows covering users to temporarily remove their phones from another user’s coverage path. Send All Calls is activated by pressing the Send All Calls button or by dialing the Send All Calls access code. It is deactivated by pressing the button a second time or by dialing the deactivate code. A user who is not assigned a coverage path with Send All Calls or Cover All Calls redirection criteria, cannot activate Send All Calls. Any attempt to activate Send All Calls is denied if the currently active coverage path does not allow it in its coverage criteria. However, if the user activates Send All Calls for a coverage path that does allow it, and then the user’s coverage path is changed by the system to a coverage path that does not allow Send All Calls: — The Send All Calls button remains lit. — Send All Calls automatically resumes when the user is changed back to a coverage path that does allow it. If a user has activated Send All Calls and has only one coverage point, and receives a call from that coverage point, the call rings silently at the user’s phone, because the coverage point is already on the call. Send All Calls is similar to Cover All Calls, discussed previously. However, you set Cover All Calls and it is used for screening the principal’s call. The principal may or may not be rung on an incoming call, depending on how this function is assigned. Send All Calls is controlled by the principal and is normally used when the principal is away temporarily. TEG calls are not affected by Send All Calls. nSend Term Send Term is the Send All Calls equivalent for TEG. Since a TEG cannot be in a coverage path, Send Term applies only to a directly called TEG.
