Hardware
Though the primary components are the same, your DEFINITY ECS can vary widely in size and appearance, depending on your capacity requirements. It may be as small as a single wall-mounted cabinet, or it may be as large as several tall cabinets linked together in the same room or even hundreds of kilometers apart. Regardless of configuration,
however, the system’s footprint is relatively small. The DEFINITY system is essentially an arrangement of port networks and circuits that
connect incoming to outgoing communications ports. Up to three port networks can be connected directly to each other. When there are more than three port networks, the connections are made through a Center Stage Switch.

Processor Port Network (PPN)

Every DEFINITY ECS has one Processor Port Network (PPN). It is often the only component in small systems. The PPN houses the Switch Processing Element.
The Switch Processing Element (SPE) contains the central processing unit, which supervises system operation. It also contains a mass storage system for loading system software and saving system translations.
Because your applic ati on requi rem en ts m ay vary widely, DEFINITY ECS has three types of SPEs av ail able with proven capacities o f 70 ,000 calls per hour, 140,000 calls per hour, and 250,000 calls per hour. The performance you realize will depend on the call processing, administrative, and maintenance activities in which your system is engaged.

Expansion Port Network (EPN)

Expansion Port Networks (EPNs) are used when the system grows beyond the capacity of a single port network or must serve geographically dispersed offices. EPNs provide additional ports as needed. A system can have up to 43 Expansion Port Networks.

Center Stage Switch (CSS)

The Center Stage Switch (CSS) is a connection hub that provides port network communication. It is an essential component of a DEFINITY ECS configuration if the system is composed of more than three port networks. Often it is incorporated into smaller configurations to allow for growth. The CSS consists of from one to three switch nodes. Switch nodes are composed of one or two switch node carriers, depending on

whether the system i s being du plica ted for enh anced reliab ility. Each carrier can reside in the PPN cabinet or an EPN cabinet. One switch node can accommodate up to 15 Expansion Port Networks.
Fiber Link Administration
Port cabinets are connected via direct fiber links or through fiber links to a Center Stage Switch to provide the connections required for voice and data information transfer. The CSS is composed of switch node carriers that are interconnected by fiber links. It provides both circuit-switched and packet-switched connections. Fiber Link Administration create s the t ra nslati on dat a defin ing the se li nks b y identi fying the end point pairs for each link. Endpoints can be an expansion interface or a switch-node-interface circuit pack.

Carriers and Cabinets

Carriers are enclosed shelves composed of vertical slots that hold circuit packs. Circuit packs make up the logic, memory, and switching circuitry for the system. Port circuit packs connect to telephones, computers, and communications lines. The carriers are designed to accept any type of port circuit pack in each circuit pack position.
Each cabinet contains at least one carrier. The circuit packs fit into connectors attached to the rear of the slots. Every connector is connecte d to s ign al b u ses an d power supplies in the cabinet.
The cabinets also house equipment that supplies power backup, ringing signal voltage, and mass storage for software translations.
There are three types of cabinets
Compact Mod ular Cabinet. (CMC)
Single-Carrier Cabinet. (SCC)
Multi-Carrier Cabinet (MCC))

Compact Modular Cabinets
The Compact Modular Ca binet (CMC) is a s mall, wa ll- or floo r-mounted un it that supp orts a single port network. It is thus well-suited to small, growing organizations. For a modest initial investment, the CMC gives you the capacity that you need now. As your organization grows, you can connect up to two more modular cabinets to expand the existing port network. Each CMC can hold up to 10 circuit packs. Figure 2 shows a Compact Modular Cabinet.

The SCC can support additional, expansion port networks, so you can add capacity as needed, up to the limit set by the overall DEFINITY system architecture. Each SCC contains a single circuit pack carrier with up to 20 circuit packs, depending on the carrier type. Up to four SCCs can be st ack ed to form a single port network, and ad ditional port networks can be connected for still more capacity. Figure 3 shows a typical single-carrier cabinet.

System Overview

Reliability and Recoverability

Reliability and Recoverability
The system is designed to recover from a power outage or other failure instantly, regardless of the source of the failure. Each port network includes a set of segmented, parallel buses. If one of the paired segments fails, the other bus segment continues to
handle communications. You can always further enhance the system’s reliability by duplicating critical components such as processors or fiber-optic links between port networks.

Configuring for Reliability /Recoverabili ty

DEFINITY ECS can be configured to meet the disaster recovery needs of any business. For example:
Calls can be routed throu gh an a lte rnate DEFINI T Y EC S if o ne s ite is des troyed or
disabled by natural or man-made disaster.
Multimedia (voice, video, data) connections to the network can all be made
redundant, in case of network failures. The system can be routed through multiple public exchanges to protect against network failures (a cable or fiber being cut, for example).
DEFINITY's universal hardware and flexible software allow systems to be re
configured quickly in emergency situations. Por t networks can be added and network routing can be changed in a matter of minutes.
The TN2211 Optical Drive will replace the present TN1656 Tape Drive. The new
Optical Drive will pro vide the sa me fun ct ionali ty as the Tape drive , s uch a s, stor age for software upgrades, translation backups, announcement file backups, core dumps, etc. It is also fas ter th an the Tape Drive. A ful l ba ckup to the Optical Driv e will take appro xim ately 20 min utes . The present Tape Drive bac kup tak es about 95 minutes.

The SREPN must be administered separately (not as a duplicated PPN) to function in a disaster recovery scenario. It will not function as a survivable remote EPN without the administration (stations, trunks, features) to support its operation.
DEFINITY ECS Network Connections
The system can be connected to public and private networks in a variety of ways.

Public Telephone Network

DEFINITY ECS supports a full range of digital and analog connections to a Public Telephone-Network Central Office, including ISDN-PRI and ISDN-BRI.

Private Telephone Networks

DEFINITY ECS supports the many kinds of private-network connections, including:
Digital telephone handsets

TCP/IP Networks

DEFINITY ECS can also connect to Ethernet Local Area Networks (LANs) and the Internet.
The optional DEFINIT Y LAN G ate w a y fe ature le ts the D EFINI TY syst em e x chang e
messages with LAN communications software.
DEFINITY ECS now supports Internet Protocol (IP) trunks using the TN802B
circuit pack and C-LAN card (TN79 9B). How ever, to connect to the netw ork and do signaling over IP, only the TN799B is required.
IP trunking is a good choice for basic, corporate voice and fax communications, where cost is a major concern. IP-trunk calls travel over a company’s intranet
rather than the Public Telephone Network. So, for the most common types of internal, corporate communications, IP trunks offer considerable savings.
IP trunking is usually not a good choice for applications where calls have to be routed to multiple destinations (as in most conferencing applications) or to a voice messaging system. IP-trunk calls are compressed to save network bandwidth. Repeated compression and decompression results in a loss of data at each stage and degrades the final quality of the signal. This is not a problem in normal, corporate voice or fax calls. They go through two or three compression cycles at most. But multipoint conference calls and most voice messaging systems add too many compression cycles for acceptable quality.
DEFINITY ECS now includes the IP Solutions feature, which supports audio and
voice transmissions over a LAN or WAN. For more information about IP Solutions, see ‘‘IP Solutions’’ on page 56.

ATM Networks

Three kinds of Asynchronous Transfer Mode (ATM) connectivity are available with DEFINITY ECS. Any standards-compliant ATM switch can serve as the switch node connecting DEFINITY ECS port networks. In this type of configuration, the ATM switch replaces the Center-Stage Switch.
The three kinds of ATM connectivity DEFINITY ECS supports are as follows:
ATM Port Network Connectivity (ATM-PNC) provides an alternative to either the
direct-connect or C ente r Stag e Sw i tch co nfi gurations for connecting the Processor Port Network (PPN) to one or more Expansion Port Networks (EPNs). ATM-PNC provides reduced infrastructure cost and improved network manageability.

ATM Circuit Emulation Service (ATM-CES) lets a DEFIN ITY ECS emulate an
ISDN-PRI trunk on an ATM facility. A TM-CES maximiz es port network capac ities b y consolidating trunking.
The ATM Trunk feature supports telephony and Wide-Area Network (WAN)
connectivity over ATM networks. ATM-WAN extends the PNC beyond a single ATM switch. It allows for use of DEFINITY ECS applications over an ATM infrastructure across locations. ATM-WAN consolidates comm u ni cat ion s tr a ffi c , all o w in g for quicker and more efficient transport of voice, data, video, and mixed media communications.

Telephones
DEFINITY ECS telephon es fall into three b asic families —Analog, Digital Communica tions Protocol (DCP), and BRI. These terms describe how each type of telephone communicates with the DEFINITY ECS switch. These families of telephones are designed to accommodate the types of communications various users require. All telephones have touch-tone dialing and the message-waiting lamp for notification of messages.

Telephones for the Global Marketplace

With help from ou r man y global customer s, Lu cent Technologies h as de v eloped the 8400, 9400, 6400 and 6200 series telephones to meet the demand for two-wire telephones in the global marketplace.
8400-Series Telephones
The 8400 digital telephones are versatile two-wire/four-wire Digital Communications Protocol (DCP) telephones with new styling that offer new flexibility and cost savings. They automatica lly detect whethe r they are plugg ed into a two-wire or four-wire digital lin e circuit card. This is a s ignifi cant b enefit becau se it pro vides an easi er tr ansi tion t o eithe r a two-line or a four-line environment, therefore reducing wiring expenses and installation adjustments . It al so al low s y o u to s a v e sp ace i nside the c abine t b y us ing 2 4-port two-wire boards in place of 16-port four-wire boards.

Handling Incoming Calls

Automatic Hold
Allow Attendants and multi-function telephone users to alternate easily between two or more calls. For example, with automatic hold, selection of a second call automatically puts the active c al l (if any) on hold and mak es the s ec ond cal l ac tive. This feature can be activated on a system-wide basis only. When automatic hold is not activated, the selection of the second call drops the first call.
Hold
Allows you to disconnect from a call temporarily, use your telephone for other call purposes, and then return to the original call.
Long Hold Recall
Visual and audib le warnings are sent to the telephone where a call has been on hol d past a specified period of time. Both visual and audible warnings are used if the telephone is on-hook. If the telephone is off-hook, a "priority ring" is used. The call is identified as a long-held call by the letters "hc" on the display. This is an optional feature at the system level.
19
Transfer
Allows telephone users to transfer trunk or internal calls to other telephones within the system without attendant as sistance . This feature pro vides a conv enient w ay to con nect a party with someone better qualified to handle the call. Single-line telephone users momentarily flash the switchhook or press the Recall button, dial the desired extension, and hang up. Multi-appearance telephone users press the Transfer button, dial the desired extension number, and press the Transfer button again. This is an optional feature at the system level.

Tr un k-to -Trunk Tran sfer
Allows the attendant or telephone user to connect an incoming trunk call to an outgoing trunk call. This feature is particularly useful when a caller outside the system calls a user or attendant and requests a transfer to another outside number. For example, a worker, away on business, can call in and have the call transferred elsewhere. The system assures that incoming Central Office trunks without Disconnect Supervision are not transferred to outgoing trunks or other incoming C ent ra l O ffi ce trunks witho ut D i sc onn ec t Supervision.
Transfer — Outgoing Trunk
to Outgoing Trunk
Allows a user or attendant to initiate two or more outgoing trunk calls and then transfer the trunks together. The transfer operation rem o ves the original us er from t he co nne cti on and conferences the outgoing trunks. Alternatively, the controlling party can establish a conference call with the outgoing trun ks and then dro p out of the conf erence , leav ing only the outgoing trunks on the conf erence . This is an optio nal enhan cement t o Trunk-to-Trunk Transfer and requires careful administration and use. DCS Trunk Turnaround may be a safer alternative to this feature.
Transfer Upon Hang-Up
20
Provides you wit h the ability to tr ansfer a call by hangi ng up instead of having to press the Transfer button a second time. You would press the Transfer button, dial the number the call is being transferred to and then hang up. This is an optional feature at the system level. You will still be able to transfer a call by pressing the Transfer button a second time.
Transfer Recall
Returns the unanswered transfer calls back to the person who transferred the call. T r ansfer Recal l uses a priority alerting signal, and the disp lay on the telephone sho ws "rt", which indicates a returned call from a failed transfer operation.
Abort Transfer
Allows a user to a bort a tra ns fer a ttem pt by pressing a non-id le lin e appearance. Th e c all being transferred would be taken off a transfer-type hold and be put on a traditional hold. The transfer will also be aborted when you hang up (going on-hook), unless Transfer Upon Hang-Up is activated on the switch. This is an optional feature at the system level.

It also al lows you to a nswer a call from any telepho ne after being page d by a telephone user or an attendant.
Misoperation Handling
NOTE:
This feature is requi red onl y in France and Italy, but it can be used at any location where the feature has been turned on.
Defines how cal ls are ha ndl ed when a misoperation occurs. A mi so per ation is when calls are left on hold when the controlling station goes on hook.
For example, a misoperation can occur under either of the following conditions:
If you hang up prior to completing a feature operation (in some cases, hanging up
completes the operation, as in call transfer). If, for example, you place a call on hold, begin to tra nsfer the call, dial an i n valid extension number, and then hang up,
that’s a misoperation.
When the system enters night service while attendant consoles have calls on hold.
The system admini st ra tor c an al ter th e s tan dard Misoperation Han dli ng to e ns ure t hat an external caller is not left on hold indefinitely, or dropped by the system after a misoperation with no way to reach someone for help.

Call Redirection
Call Forwarding
Call Forwarding provides four functions:
Call Forwarding All Calls — Allows calls to be forwarded to an internal extension,
external (off-net) number, an attendant, or an attendant group.
Call Forwarding Override — Allows the user at the forwarded-to extension to
override Call Forwarding and either initiate a call or transfer a call back to the forwarded-from extension.
Call Forward Busy/Don’t Answer — Allows calls to be forwarded when the called
extensio n is b u sy or wh en the call is not ans w ere d after an adm inis tr ab le int erval. I f the extension is bus y, the call forwards immediately. If the extension is not bus y, the incoming call rings the called extension, then forwards only if it remains unanswered longer than the administered interval.

Call Forwarding Off Net — Allows calls forwarded off net to be tracked for busy or
no-answer conditions. The system brings the call back for further call-coverage processing if specified conditions are met. This feature is particularly useful for Telecommuters, who can have their on-site office calls forwarded to their home offices.
Call Coverage
Call Coverage provides automatic redirection of calls that meet specified criteria to alternate answering positions in a Call Coverage path. A coverage path can include any of the following: a telephone, an attendant group, a Uniform Call Distribution (UCD) hunt group, a Direct Department Calling (DDC) hunt group, an Automatic Call Distribution (ACD) hunt group, a voice messaging system, or a Coverage Answer Group (CAG) established to answer redirected calls.
In addition to redirecting a call to a local answering position, you can administer Call Covera ge to:
Redirect calls based on time-of-day

To activate and deac tiv ate th is featu re, the attendant typically presses the Night button on the principal attendant console or designated console.
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 a busy tone. They do not queue for the attendant.
Trunk Answer from Any Statio n allo ws tel eph one users to answer all incoming calls
to the attendant when the attendant is not on duty and when other voice terminals have not been designated to answer the calls. The incoming call activates a gong, bell, or chime and a voice-terminal user dials an access code to answer the call.
Trunk Group Night Service allows an attendant or a designated telephone user to
individually assign a trunk group or all trunk groups to the night service mode. Specific trunk groups individually assigned to the service are in Individual Trunk Night Service Mode. Calls coming into these trunk groups are redirected to designated night service extensions. Incoming calls on other trunk groups are processed normally.

Bridged Call Appearance — Multi-Appearan ce Telephone
Allows calls ma de to or from a primary teleph one use r’s extension number to be handled from more than one telephone. A bridged call appearance is set up by administering a primary extension and the button number associated with it on a multi-lamp button on another telephone . One way this feature is most often used is by secretaries or as sistants who answer or handle calls to the primary extension (an executive, for example). When the primary extension receives a call, the bridged call appearance flashes or rings on all telephones administered with this feature. The call can be answered by anyone having a telephone with this feature a nd handled as if the primary ex tension u ser was a ns wering it. The maximum number of bridged appearances has been expanded from 25 to 64 with DEFINITY ECS R8.
Bridged Call Appeara nce — Single-Line
Telephone
Allows single-l ine tel ephone s use rs to ha v e a bridged appear anc e on a m ulti-a ppear an ce telephone.
Temporary Bridged Appearance
Allows multi-appearance telephone users in a terminating extension group or personal central office line group to bridge onto an existing group call. If a call has been answered using the Call Pickup feature, the originally called party can bridge onto the call. This feature also allows a called party to bridge onto a call that redirects to coverage before the called party can answer it.
27
Privacy — Manu al E xcl u si on
Allows multi-appearance telephone users to keep other users with appearances of the same extension number from bridging onto an existing call. Exclusion is activated by pressing the Exclusion button on a per-call basis.
Privacy-Auto Exclusion
When the Class of Service is set for the Automatic Exclusion option, the feature is activated when you take your telephone off-hook. The feature can be deactivated when you push the Exclusion button before dialing a call or during a call. An excluded call that is on hold can be taken off hold by any telephone that has a bridged appearance of the telephone that put the call on hold.

Circular Station Hunting
This new hunt group type is an alternative to the "ddc" or "hot-seat" algorithm in a hunt group. DEFINITY ECS keeps track of the last extension in the hunt group that received a call. When another incoming call arrives, it is sent to the next idle extension, bypassing the exten sion that ha d rece iv ed t he pr e vio us call . The f irst e xte nsion in the hunt grou p wil l no longer be the busiest telephone while the others in the group are sitting idle.

Emergency Access to the Attendant
Provides for emergency calls to be placed to an Attendant. These calls can be placed automatically by the system or can be dialed by system users. Emergency access calls can receive priority handling by the Attendant.
Crisis Alert
Crisis Alert uses both audib le and vis ual al erting to notify desig nated e x tensions whe n an emergency call is made. Audible alerting sounds like an ambulance siren. Visual alerting
flashes the CRSS-ALRT button lamp and the display of the caller’s name and extension. Crisis Alert’s display of the origin of the emergency call enables the attendant or other user to direct emergency-service response to the caller.
If an emergency call is made while another crisis alert is still active, the incoming call will be placed in the q ueue . If th e sys tem is ad mini ster ed so t hat all users mu st resp ond, th en eve ry user must resp ond to every call, in which case the calls are not n ecess arily queued in the order in which they were made. If the system is administered so that only one user must respond, the first crisis alert remains active at the phone where it was acknowledged. Subsequent calls are queued to the next available station in the order in which they were made.
Crisis Alert can also send notif icatio n of an e mergen cy ca ll to a di git al page r . In th is case , it sends a message of 7 to 22 digits to the pager and displays a crisis alert code, an extension and room number, and a main number (if one is entered). The person paged thus knows the origin of the emergency call and can direct emergency-service response to the appropriate location. To use Crisis Alert with a digital pager, the system is administered so that at lea st one digita l set has a CRSS-ALR T b utton an d the Alert Pager field is set to y. Any station with a CRSS-ALRT button and a pager receives the correct alert.

This capability is provided by assigning a Trunk ID button to the attendant console or telephone . This feature i s particularly helpful for identi fying a faulty trunk. Tha t trunk can then be removed from service and the problem quickly corrected.
Crisis Alert
Visibly and audibly alerts Attendants when an emergency call is placed. The feature indicates from where an emergency call is made, which allows the Attendant to direct emergency-service res ponse to the call er. Though often used in the hospi tality indu stry, it can be set up to work with any standard attendant console.

Attendant Features
Audible alerting sounds lik e an am bul ance siren . Visual ale rting consists of flash ing of the crisis-alert button lamp and d isplay of the caller name and extension. When crisis alerting is active, the console is placed in position-busy mode so that no other incoming calls interfere with the emergency call. The console can still originate calls. The Attendant must press the position-busy button to unbusy the console and the crisis-alert button to deactivate audible and visual alerting.
Trunk Gro up Access
Allows an Attendant to control trunk groups and prevents telephone users from directly accessing a controll ed trunk grou p. This allows the At tendant to monitor the use of these trunk groups. By watching the lamps associated with the trunk groups, the Attendant can determine if the number of busy trunks in a specific trunk group has reached a preset warning level and if all trunks in a specific trun k group are busy. The Attendant can then handle other calls to these trunk groups accordingly.
Direct Extension Selection With Busy Lamp Field
Allows the Attendant to keep track of extension status — whether the extension is idle or busy — and to place or extend calls to extension numbers without having to dial the extension number. The Attendant can use this feature in two ways: using standard Direct Extension Selection access, or using enhanced Direct Extension Selection access.
46
Trunk Group Busy/Warning Indicators to Attendant
Provides the Attendant with a visual indication that the number of busy trunks in a group has reached an administered level. A visual indication is also provided when all trunks in a group are busy. This feature is particularly helpful to show the Attendant that the Attendant Control of Trunk Group Access feature needs to be invoked.
Room Status (Hospitality Industry)
Allows an Attendant to see whether a room is vacant or occupied and the housekeeping status of each room. This feature is only availabl e when you have Enhanced Hospitality enabled for y o ur s ystem . Th is feature combines the property managem en t ca pab il iti es o f Check-In/Check-Out and Housekeeping Status but does not require that you have a Property Management System.

Attendant Direct Trunk Group Selection
Allows the Attendant direct access to an idle outgoing trunk by pressing the button assigned to the trunk group. This feature eliminates the need for the Attendant to memorize, or look up, and dial the trunk access codes associated with frequently used trunk groups. Pressing a labelled button selects an idle trunk in the desired group.

Centralized Attendant Service

Enables Attendant services in a private network to be concentrated at a central location. Each branch in a Centralized Attendant Service has its own listed directory number or other type of access from the public network. Incoming calls to the branch, as well as calls made by users directly to the Attendants, are routed to the centralized Attendants over Release Link Trunks.

Attendant with DCS

Control of Trunk Group Access
Allows an Attendan t at any node in th e D istributed Communi cat ion Sy ste m (DC S) to ta ke control of any outgoing trunk group at an adjacent node. This is helpful when an Attendant wants to prevent telephone users from calling out on a specific trunk group for any number of reasons, such as reserving a trunk group for incoming calls or for a very important outgoing call.
47
Direct Trunk Group Selection
Allows the Attendant direct access to an idle outgoing trunk in a local or remote trunk group by pressing the button assigned to that trunk group. This feature eliminates the need for the Attendant to memorize, or look up, and dial the trunk access codes associated with frequen tly us ed trunk g roups . Di rect Trunk Group Sele ction is in tended to expedite the handling of an outgoing call by the Attendant.
Display
Shows call-re lated information that helps the A ttendant to operate the console. Also shows personal service and message information. Information is shown on the alphanumeric display on the Attendant console. Attendants may select one of several available display message languages: English, French, Italian, or Spanish. In addition, your company may define one additional language for use by users and Attendants on their display.

IP Solutions
NOTE:
To maximize voice quality using IP Solutions, you must consider both your hardware and network configurations. For example, with IP Softphones, you can send the audio over traditional circuit switch lines, providing high quality voice, or over IP using LAN connections. When making calls over the LAN, voice quality will vary and may be unacceptable if you don’t tune your computers and data network. For example, systems without full duplex audio cards and switch Ethernet ports are not recommended and will provide poor audio quality.
In addition, IP call capacities currently do not match those of traditional switch lines. See Chapter 4 in the inofmration on call performance.
IP Solutions supports two trunk configurations and three types of softphones. It uses a new IP Interface circuit pack inside the DEFINITY ECS. This IP Interface is new with Release 8. It can operate in either of the following two modes:
IP Trunk—used for IP trunk connections . T his i s the d efault mode for t he R eleas e 8
IP Interface, and this mode makes it compatible with Release 7 systems.

NOTE:
IP Trunk is the default mode for the Release 8 IP Interface only because it may also be used to replace the IP Interface in Release 7 systems. In a Release 8 system, however, the Release 8 IP Interface should be used in MedPro mode.
MedPro—used for H.323 trunk connections and H.323 voice processing for IP
softphones. This mode requires the new C-LAN circuit pack.
DEFINITY ECS supports multiple Release 8 IP Interfaces operating in a mixture of these two modes or a combination of Release 7 IP Interfaces (operating in the IP Trunk mode) and Release 8 IP Interfaces (operating in either mode). However, a Release 7 or Release 8 IP Interface operating in IP Trunk mode cannot comm uni cate with a Relea se 8 IP Interface operating in MedPro mode.

Overview
The following features are designed for use in the hospitality industry. Other features listed elsewhere may be of use in this industry, however. The Attendant Crisis Alert feature is primarily used in lodging establishments. That feature is a basic feature because it is available on any system that has the appropriate attendant console.

Automatic Wakeup

Allows Attendants, front desk users, and guests to request that a wakeup call be placed automatically to a certain e xtensi on nu mber at a late r time . When a w ak e up call is placed and answered, the system can provide a recorded announcement (which can be a speech synthesis announcement), music, or simply silence. With the Integrated Announcement feature, multiple announcements enable international guests to use wakeup announcements in a variety of languages.
61

Do Not Disturb

Allows guests, Attendants, and authorized front desk users to request that no calls, other than priority calls, be connected to a particular extension until a specified time.

Dual Wakeup

This capability is part of the Automatic Wakeup Hospitality Hotel/Motel feature. Dual Wakeup allows each extension to request two wakeup calls within one 24-hour period.

Room Activated Wakeup With Tones

This capability is part of the Automatic Wakeup Hospitality Hotel/Motel feature. Room Activated Wakeup With Tones allows guests to schedule wakeup calls via tones that prompt for the time they want to receive the wakeup call.

The Hospitality features set (Auto Wakeup, Do Not Di stu rb, Property Management Syste m) is the same on both packages.

Names Registration

Automatical ly sen ds a gue st ’s name and room e xte ns ion from the Pro pe rty Manageme nt System (PMS) to the DEFINITY ECS at check-in, and automatically removes this information at check-out. The information may be displayed on any attendant console or display-equipped telephone at various hotel locations (for example, Room Service or Security).

Suite Check-In via the Hunt-to Feature

This feature is basically for the Hospitality Industry. Suite Check-In via the Hunt-to feature allows more than one station to be "checked- in" at one time. This is useful for a guest room that may have multiple extensions. This feature allows all extensions to be "checked-i n" at the sam e time .

Property Management System (PMS) Digit to Insert/Delete
Many customer configurations base the room telephone extension on the room number by adding an extra leading digit. The PMS Insert/Delete Digit feature allows users to delete the leadi ng dig it of t he e x tensio n in mes sage s. The fea ture is use ful for a hotel that has multiple extensions sharing an extra leading digit in front of the room number. The leading digit is automatically inserted when the message goes to the PBX.
NOTE:
The PMS interface supports 3-, 4-, or 5-digit extensions, but prefixed extensions do not send the entire number across the interface. Only the assigned extension number is sent. Therefore, you should not us e prefixed extensions for numbers that are also going to use the Digit to Insert/Delete function.

Single-Digit Dialing and Mixed Station Numbering

Allows hotel staff and guests easy access to internal hotel/motel services and provides the capability to associate room numbers with guest room telephones. The feature provides the following dial plan types: single-digit dialing, prefixed extensions, and mixed numbering.
63

Auto-Selection of DID Numbers

Allows the hotel to give guests a telephone number that is not associated with the room number. The telephone number will be a Direct Inward Dialed (DID) number and will change each time someone checks in. There is an Automatic Digit Rotation that allows the number to change and be picked randomly from a block of DID numbers whenever a new guest checks in.

Station Hunt Before Coverage

This feature changes the interaction that occurs between station hunting and call coverage. Station Hunt before Coverage causes a call going to a busy station to go through a station hunting process before going to coverage. If all the stations in the Hunt group are busy, the call will go to the coverage path.

Troubleshooting

Automatic Circuit Assurance

Assists in identifying possible trunk problems. The DEFINITY ECS maintains a record of the performance of individual trunks and automatically calls a designated user when a possible fail ure is det ected. Thi s feature provid es better service through early detecti on of faulty trunks and consequently reduces out-of-service time.

DCS Automatic Circuit Assurance

Allows a user or Attendant at one node to activate or deactivate Automatic Circuit Assurance referral calls for the entire DCS network. This transparency allows the referral calls to originate at a node other than the node that detects the problem.

Busy Verification of Terminals and Trunks

Allows Attendants a nd us ers of m ul t i-a ppe ar an ce telephones to m ake test calls to trunks, telephones, an d hunt g roups to c hec k the sta tus of an apparently bus y resourc e. Wit h this feature, an Attendant or multifunction telephone user can distinguish between a telephone that is truly busy and one that only appears busy because of some problem. You can also use the feature to quickly identify faulty trunks.

Facility Busy Indication

Allows users of multi-appearance telephones to see which lines, trunk groups, terminating extensi on grou ps, hu nt grou ps, or paging z ones (called res ources o r facilities ) are busy. When the lamp associated with the resource is lit, the resource is bu sy.
You can store extension numbers, trunk group access codes, and Loudspeaker Paging access codes in a Facility Busy Indication button. The Facility Busy Indication button provides direct access to any of the facilities.

Facility Test Calls

Allows telephone users to make test calls to access specific trunks, dual tone multifrequency receivers, time slots, and system tones. The user dials an access code and makes the test call to make sure the facility is operating properly. Security measures are included to prevent unauthorized use.

Packet Error History

Provides a 24-hou r history of important pac ket le v el st atistics tha t indirectl y indica te some LAN performance characteristics. The 24-hour history gives the ability to look back at these measures if the trouble cleared.

Variable Length Ping

Provides an enhancement to the ping command included in R7.1. This enhancement specifies a longer packet to be sent by ping and shows if a router or host has a problem fragmenting or integrating transferred packets.
Information and Reports

Recent Change History

Allows the system manager to view or print a history report of the most recent administration and maintenance changes on the switch. This report may be used for diagnostic or information purposes.

Service Observing

Allows a specified user, such as a supervisor, to observe or monitor another user’s calls. A vector directory number call can also be observed. Observers can observe in listen-only or listen-and-talk mode. You set up Service Observing to observe a particular extension, not all calls to all extensions at a terminal.
71
NOTE:
Service Observing may be subject to federal, state, or local laws, rules, or regulations or require the consent of one or both of the call parties. Familiarize yourself and comply with all applicable laws, rules, and regulations before using this feature.

Calling Party/Billing Number (CPN/BN)

Allows the sy stem to t ransmit C alling P a rty Number/Billing N umber (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. It is used with an adjunct application.

Call Charge Information

Provides two ways to know the approximate charge for calls made on outgoing trunks:
Advice of Charge — For ISDN trunks
Advice of Charge (AOC) collects charge information from the public network for each outgoing call. Charge advice is a nu mber representing the cost of a call; it is recorded as either a charging or currency unit.
Periodic Pulse Metering — For non-ISDN trunks
Periodic Pulse Metering (PPM) accumulates pulses transmitted from the public network at periodic i ntervals d uring an out going trun k call. At the end of the c all, the number of pulses collected is the basis for determining charges.
Call-charge information hel ps y ou to acco unt for th e cos t of outgo ing ca lls w ithou t wai tin g for the next bi ll from y our netw ork pro vider . T his is espe cially i mportant in count ries where telephone bills are not itemized. You can also use this information to let employees know the cost of their phone calls, and so encourage them to help manage the company’s telecommunications expenses.
NOTE:
This feature is not offered by the public network in some countries, including the United States.
In addition, the Pass Advice of Charge to BRI endpoints feature will transparently pass AOC information that has been received from PRI networks to WCBRI endpoints.

Bulletin Board

Provides a place on the switch where you can post information and receive messages from other switch users, including Lucent Technologies personnel. Anyone with appropriate permissions can use the bulletin board for everyday messages. In addition, Lucent Technologies personn el can lea v e high-p riority me ssag es , whi ch are disp la y ed on the first 10 lines of the bulletin board.

Administration Without Hardware
Allows you to administer telephones that are not yet physically present on the system. This feature works the same as administration with hardware: when stations are moved, user-activated features such as Call Forwarding and Send All Calls are preserved and functional. This greatly facilitates the speed of setting up and making changes to the telephones on the system.

Terminal Translation Initialization (TTI)

DEFINITY ECS provides Terminal Translation Initialization, a feature that works with Administration Without Hardware. Terminal Translation Initialization associates the terminal translation data with a specific port location through the entry of a special feature-access co de, a Terminal T ranslation Initiali zation security code, an d an extension number from a terminal that is connected to a wired (but untranslated) jack.

Tenant Partitioning

Allows partitioning of the DEF INITY ECS in order to lease the system’s services and features to tenants. This provides attractive new services and revenue for “virtual” landlords. It provides the robust features of a large system at affordable rates to small business tenan ts. DEFIN ITY ECS supports up to 100 partitions and 27 Attendant Grou ps. Multiple Attendant Groups can be assigned to each partition. Stations, hunt groups, and other endpoints assigned to a Class of Service can be partitioned. Network routing pattern preferences also support the assigned Tenant Partitioning. Tenant Partitioning also allows you to assign a unique music source for each tenant partition for customers who are put on hold.

Trunk Group Circuits

Trunks provide the communications links between DEFINITY ECS and other switches, including Central Office switches and other premises switches. Trunks that perform the same function are grouped together and administered as trunk groups. Trunks interface with DEFINITY ECS via port circuit packs. DEFINITY ECS trunk group circuit types include the following:

Local Exchange Trunks

Local exchange trunks connect DEFINITY ECS to a Central Office. The following are some of the types available:
Central Office trunks, which connect DEFINITY ECS to the local Central Office for
incoming and outgoing calls
Foreign Exchange trunks, which connect DEFINITY ECS to a Central Office other
than the local one
Wide Area Telecommunications Service (WATS) trunks, which allow you to place
long-distance outgoing voice-grade calls to telephones in defined service areas. The calls are priced according to distance in the service area, length of the call, time of day, and the day of the week
800-service trunks, which let your business pay the charges for inbound
long-distance calls so that callers can reach you toll-free
Direct Inward Dialing (DID) trunks, which connect DEFINITY ECS to the local
Central Office for incoming calls dialed directly to stations without Attendant assistance
Digital Service 1 (DS1) trunks, which can be used to provide T1 or ISDN Primary
Rate Interface (PRI) service

Tie Trunks

Tie trunks carry communicati ons betw ee n DEF INITY E CS and o ther switches in a private network. Several types of trunks can be used, depending on the type of private network you establish .

Auxiliary Trunks

Auxiliary trunks connect devices in auxiliary cabinets with the DEFINITY ECS. Some of the features that are supported with this type of trunk are recorded announcements, telephone dictation service, malicious call trace, and loudspeaker paging.
Central Office: The location housing te lephone s w itching equipme nt that pr ovide s local
telephone service and access to toll facilities for long-distance calling.
Advanced Private Line Termination (APLT)
Provides access to and termination from CO (Central Office)-based private networks; namely, Common Control Switching Arrangements (CCSA) and Enhanced Private Switched Communications Service (EPSCS). APLT trunks are physically the same as those used for analo g tie t runks, where the tru nk signa ling i s compa tib le with EPSCS and CCSA network switches. The outgoing APLT trunk repeats any number of digits to the private network as dialed. APLT trunks can tandem through the PBX from EPSCS network only; CCSA networks require an Attendant to complete the call.
Direct Inward/Outward Dialing (DIOD)
Traditionally, CO (Central Office) trunks and DID (Direct In w ard Dial ing) trun ks interf ace a PBX with a Central O ffice . A C O trunk se rvices outgoing calls and ac cepts inco ming c alls that are terminated at the Attendant. A DID trunk is used for calls that need to be terminated without an Attendant interaction.
The DIOD trunk combines the features of a CO trunk and a DID trunk to provide both outgoing and incoming calls with addressing information in both directions.

IP Trunks

IP trunk groups ma y b e de fine d as a virtual priv ate n etw ork’s tie line s betw ee n DEFINITY ECS systems or ITS-E servers. Each DEFINITY IP Trunk circuit pack provides a basic twelve-port package that can be expanded up to a total of 30 ports. The number of ports that are defined will corres pond to the total number of si multan eous call s transm itted ov er the IP Trunk Interface.
The benefits of IP Trunk include a reduction in long distance voice and fax expenses, facilitating global communications, providing a full function network with data and voice convergence and optimizing networks by using the available network resources.

ISDN Trunks

Gives you access to a variety of public and private network services and facilities. The ISDN standard consists of layers 1, 2, and 3 of the Open System Interconnect (OSI) model. DEFINITY ECS can be connected to an ISDN using standard frame formats: Basic Rate Interface (BRI) and the Primary Rate Interface (PRI).
An ISDN provides end-to-end digital connectivity and uses a high-speed interface which provides service-independent access to switched services. Through internationally accepted standard interfaces, an ISDN provides circuit or packet-switched connectivity within a network and can link to other ISDN supported interfaces to provide national and international digital connectivity.
Integrated Services Digital Network—(Basic Rate Interface (ISDN-BRI)
Enables connection of the system to equipment or endpoints that support an Integrated Services Digital Network (ISDN) by using a standard format called the Basic Rate Interface (BRI). This fe atur e i s a 19 2-Kbp s int erfa ce tha t c arries t w o 64 -Kbps B-cha nnels and one 16-Kbps D-channel.
ISDN is a global access standard that uses a layered protocol. It eliminates the need for multiple, se parate ac cess arr ange ments for v oice , data, fac simile , and vi deo services an d networks. Using the same pair of wires that now carry simple telephone calls, ISDN can deliver voice, data, and video services in a digital format.
The ISDN-BRI Trunk circuit pack al lows DEF INITY ECS to suppo rt the T interface and the S/T interface as defined by ISDN standards (ITU-T recommendation I.411). The circuit pack provides eight ports to the network and supports two B channels and one D channel. The ISDN-BRI Trunk provides the following advantages:
Provides an inexpensive way to connect to ISDN services provided by the network
provider
Meets almost all ETSI Country protocol requirements
Supports essential (not supplementary) ISDN services
BRI trunks support public-network access outside the U.S. on point-to-midpoint connections, with the restriction that DEFINITY ECS must not be configured in a passive bus arrangement with other BRI endpo ints. ISDN-BRI trunks can be used as inter-PBX tie lines using the QSIG peer protocol.
