Your Responsibility for Your System’s Security

Toll fraud is the unauthorized use of your telecommunications system by an unauthorized

party, for example, persons other than your company’s employees, agents, subcontractors, or persons working on your company’s behalf. Note that there may be a risk of toll fraud associated with your telecommunications system and, if toll fraud occurs, it can result in substantial additional charges for your telecommunications services.

You and your system manager are responsible for the security of your system, such as programming and configuring your equipment to prevent unauthorized use. The system manager is also responsible for reading all installation, instruction, and system administration documents provided with this product in order to fully understand the features that can introduce risk of toll fraud and the steps that can be taken to reduce that risk. Lucent Technologies does not warrant that this product is immune from or will prevent unauthorized use of common-carrier telecommunication services or facilities accessed through or connected to it.

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

Hardware

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

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

■ Data-communications equipment, including data modules and data terminal

equipment.

■ Attendant and voice messaging systems

■ Multimedia and video conferencing equipment

■ Call Center systems

■ Hospitality systems

■ Auxiliary loudspeaker-paging and music-on-hold equipment

■ Peripherals, such as journal printers and call detail-recording equipment.

■ Asynchronous Transfer Mode or ATM

■ IP solutions, such as IP trunking and IP softphones

■ Other private-network switches

DEFINITY ECS Network Connections

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.

9400-Series Telephones

The 9400 digit al tel ephones, also known as Europhon es, provide inexpensive support for two-wire installations, while still providing a European design. Three models of the 9400 telephones are available in gray and cream white. The 9403, 9410B, 9410D, and 9434 telephones are similar in design and features to the 8400 series.

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.

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

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.

Call Park

Allows you to put a call on hold and then retrieve a call from any other telephone on the system. This is helpful when you are on a call and need to go to another location for information. 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.

Manual Messag e Waiting

Allows multi-appearance telephone users to light the status lamp associated with the manual Message Waiting button at another multi-appearance telephone. They do this by simply pressing a button on their own telephone. This feature can be administered only to

pairs of telephones such as a secretary and an executive. The secretary might press the button to signal to the executive that a call needs answering or someone has arrived for an appointment. The executive might use the button to indicate that he or she should not be disturbed.

Internal Automatic Answer

Allows specific tel ephone s to answer incoming internal calls automatically. This feature is intended for use with telephone s that hav e sp eake rphones or headset s. You simply press an Internal Automatic Answer feature button, and calls are automatically answered when the telephone is idle. Internal and Distributed Communications System (DCS) calls can be answered using Automatic Answer, but only attendants can use Automatic Answer to answer external calls directed to the attendant.

Recall Sign al ing

Recall Signaling al lo ws th e user of an a nalog statio n to pl ace a call o n hold , u se the v oi ce terminal for other call purposes, and then return to the original call.

Local Call Timer Automatic Start/Stop

Automatically starts the local timer of a 6400 series telephone when a call is received. The timer is stopp ed autom atically w hen a ca ll is en ded. When a call i s placed on hold the timer continues to run, but is not displayed. When the call comes off hold, the total elapsed call-time disp lays.

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.

Telephone Features

■ 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

■ Redirect calls to a remote location

■ Allow users to change bac k and fo rth between two lead-c overage paths from either

an on- or off-site location

Coverage Callback

Allows a covering user to leave a message for the called party to call back the person who called.

Coverage Incoming Call Identification

Allows mult i-appear ance tele phones us ers withou t a displa y in a Cov er age Ans w er Group to identify an incoming call to that group.

Go to Cover

Allows users who call another internal extension to send the call directly to coverage.

Send All Ca lls

Allows users to temporarily direct all incoming calls to coverage regardless of the assigned call-coverage redirection criteria. Covering users can temporarily remove their voice terminals from the coverage path. The feature is activated and deactivated via a button or access code.

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.

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.

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.

Speed/Convenience Calling

Abbreviated Dialing

Provides lists of stored numbers you can use to:

■ Place local, long-distance, and international calls

■ Activate features

■ Access remote computer equipment

You simply dial the list number and the one-, two-, or three-digit number associated with the telephone number you want. The number is then automatically dialed by the system. A frequently called number can be stored on an abbreviated dialing button that you need only press once to make the call.

Abbreviated Dialing Labeling

Labeling of Abbreviated Dialing (AD) Butto ns on Softkeys allo w s users of 840 0 and 6400 series display telephone sets to administer labels for the AD buttons that appear on their softkeys. These personalized labels appear on the menu display.

Abbreviated Dialing On-Hook Programming

On-Hook Programming allows users of 8400 and 6400 series telephone sets with enabled speakers to access the programming mode without going off-hook during avail able call appear an ce s . Signaling changes fr om D T MF to the S-channel, allowing the use of a longer (60 sec onds) ti me-ou t period. Signali ng will remain DTMF and the curr ent time-out period of 10 seconds will still apply to non-display telephone sets.

Enhanced Abbreviated Dialing

Supplements Abbreviated Dialing by providing one enhanced number per system. Enhanced num ber lists can contain any number or dial access code. System Administrators designate privileges for group number lists, system number lists and

enhanced number lists. With privileged lists, users can access otherwise-restricted numbers (e.g., Stations without long-distance access can be programmed to access specified long-distance numbers).

Active Dialing

6400 series telephone sets ha v e a diali ng option where the set will se nd S-chann el b utton codes when the user pres ses a number on t he dial pad when on-hook.

Telephone Self-Administration

Allows you to program feature buttons on 6400-series telephones yourself.

Automatic Callback

Allows internal users who placed a call to a busy or unanswered internal telephone to be called back automatically when the called voice terminal becomes available.

When a user activates Automatic Callback, the system monitors the called telephone. When the called t ele phone becomes a vailable to receive a cal l, the sy s tem ori gin ate s the Automatic Callback call. The originating party receives priority ringing. The calling party then lifts the handset and the called party receives the same ringing provided on the original call.

Ringback Queuing

Places calls in an ordered queue (first in, first out) when all trunks are busy. The telephone user who is trying to make a call is automatically called back when a trunk becomes available, and hears a distinctive three-burst signal when called back.

Last Number Dialed

Allows you to automatically redial the last number dialed. The system saves the first 24 digits of the last number dialed, whether the call attempt was manually dialed or dialed using Abbreviated Dialing. When you press the Last Number Dialed button or dial the Last Number dialed feature access code, the system places the call again.

Remote Access

Permits authorized callers from remote locations to access the system via the public network and then use its features and services.There are a variety of ways of accessing the feature. After gaining access, you hear a system dial tone, and, for system security, may be required to dial a barrier code.

Recorded Te lephone Dictation Access

Allows telephone users, incl uding Remot e Access and incom ing tie trunk users , to access dictation equipment. The dictation equipment is accessed by dialing an access code or extension number . Th e s tart/stop fu nc tio n c an b e voice or dial controlled. Other functions such as initial activation and playback are controlled by additional dial codes.

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.

Manual Originating Line Service

Connects single-line telephone users to the attendant automatically when the user lifts the handset. The attendant number is stored in an Abbreviated Dialing list. When the telephone user lifts the handset, the system automatically routes the call to the attendant using the Hot Line Service feature.

Trunk Flash

Trunk Flash allows a feature or function button on a multifunction telephone or attendant console to be assigne d as a F lash b ut ton. Pressi ng this b utton whi le con nected to a trunk (which must have been administered to allow Trunk Flash) causes the system to send a flash signal out over the connected trunk.

Trunk Flash enables multifunction voice terminals to access central office customized services that are provided by the Central Office to which DEFINITY ECS is connected. These services are electronic features, such as conference and transfer, that are accessed by a sequence of flash signal and dial signals from the DEFINITY System station on an active trunk call. The Trunk Flash feature can help to reduce the nu mber of

trunk lines connected to th e D EFINITY system. “Digit 1 as Fla sh ” as us ed i n Italy and the United Kingdom will not serve as the flash button in this application.

Special Dial Tone

Provides the ability to play a Special Dial Tone whenever an analog set is not able to receive calls. When such conditions as Call Forward All Calls, Call Forward Busy/NA, Send All Calls or Do Not Dist urb are activ ate d on a teleph one set, a Sp ecial Di al Tone lets you know that you cannot receive any calls.

Telephone Displays

Voice Terminal Display

Provides multi-appearance telephone users with updated call and message information. This information is displayed on a display-equippe d teleph on e. Th e information displ a y ed depends upon the display mode selected by the user. Information that allows personalized call answering is available on many calls.

Users may select any of the fo llowin g as the displa y m essage language : English (default), French, It alian, or Spanish . In additi on, mess ages can be admin istered on the syst em in a fifth language. The language for display messages is selected by each user.

Voice Messaging and Call Coverage

Often an A UDIX sy stem is set up as the las t point on a call-co v e ra ge path, as in Figure 8. A secretary or colleague who answers a redirected call intended for you can als o tran sfer the caller to your AUDIX mailbox. The caller may prefer to leave voice-mail for you if the message is personal, lengthy, or technical.

Many other options are av ailab le . For e xa mple, a caller can redirec t a call from the AUDIX system to an attendant. Or the caller can transfer to another extension instead of leaving a message. You can even have the AUDIX automated attendant answer all calls to the company and s end ca lls to v arious extensions. In this case, cal lers ar e instru cted t o enter keypad commands to direct the call.

Voice Message Retrieval

Allows telephone users, remote access users, and attendants to retrieve Leave Word

Calling and Call Coverage voice messages. It can be used to retrieve a user’s own messages or messages for another user. However, a different user’s messages can be retrieved only by a user at a telephone or attendant console in the coverage path, by an administered system-wide message retriever, or by a remote-access user when the extension and associated security code are known. The system restricts unauthorized users from retrieving messages.

Message-Retrieval Options

With the Message - Waiting Lamp on their telephon es, employees always know w h en th e y have messages. Messages can be retrieved in a variety of ways, such as:

■ Display retrieval — Users having digital telephones with displays or a personal

computer integrated with a telephone can display messages.

■ Speak-to-Me — Usi ng a n y touc h-t one telephone, em ployees can dial Speak-to-Me

and hear a synthesized voice read their messages over the telephone.

These message-retrieval options can be assigned to users individually.

Provides for automatic placement of a data call when the originator hangs up. Data Hot Line may be used for security purposes. This feature offers fast and accurate call placement to commonly called data endpoints. Data terminal users who constantly call the same number can use Data Hot Line to automatically place the call when they hang up the telephone.

Default Dialing

Provides data terminal users who dial a specific number the majority of the time a very simple method of dialing that number. This feature enhances Data Terminal (Keyboard) Dialing by allowing a data terminal user to place a data call to a preadministered destination in several different ways, depending on the type of data module. Data Terminal Dialing and Alphanumeric Dialing are unaffected.

Data Privacy

Protects analog data calls from being disturbed by any of the system’s overriding or ringing features. Data Privacy is activated when you dial an activation code at the beginning of the call.

Administered Connections

Automatically establishes an end-to-end connection between two access or data endpoints based on administered attributes. This feature provides capabilities such as alarm notification, including an administrable alarm type and threshold; automatic restoration of connections established over a Software-Defined Data Network; ISDN-PRI trunk group [service ma y be referred to as ISDN-PRI (A C/AE) Service]; sc heduled as w ell as continuous connections; and administrable-retry interval for failed connection attempts.

Multimedia Calling

Multimedia calls are initiated with voice and video only. Once a call is established, one of the parties may initiate an associated data conference to include all of the parties on the call who are capabl e of supporting data. The data conference is controlled by an adjunct device called an Expansion Services Module (ESM).

Multimedia Call Early A nswer on Vectors and Stations

Early Answer is a feature applied to multimedia calls in conjunction with conversion to voice. Early Answer:

■ Answers the data call

■ Establishes the multimedia protocol prior to completion of a converted call

■ Ensures that a voice path to/from the originator is availabl e when the (voice) call is

answered

For an incoming call, Early Answer answers the dynamic service-link calls when the destination endpoint answers, unless Early Answer is specified during routing or termination processing.

Multimedia Applications Server Interface

The Multimedia Applica tions Serve r Interface pro vide s a link betw een the DEF INITY ECS and one or more Multimedia Communications eXchange nodes. A Multimedia Communications eXchange is a stand-alone multimedia call processor produced by Lucent Technologies. This new link to DEFINITY ECS enhances the capabilities of each Multimedia Communications eXchange system by enabling it to share some of the DEFINITY ECS features. In particular, the interface provides the following advantages:

■ Call Detail Recording (CDR)— The capture of call detail records so you can

analyze the call patterns and usage of multimedia calls just as DEFINITY administrators analyze normal calls.

■ Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) — The

intelligent selection of the most cost-effective routing for calls, based on available resources and your carrier preference. The system may select public trunks via DEFINITY Multimedia eXchange (MMCX)

■ Voice Mail Integration — You can access your DEFINITY or INTUITY AUDIX voice

messaging system from a Multimedia Communication eXchange (MMCX).

Local Area Network Connectivity (LAN)

The DEFINITY LAN Gateway feature l ets the DEFINITY system exchange messages with PC/LAN-based communications software. The Control LAN (C-LAN) interface simplifies connections between adjunct equipment and DEFINITY. It provides TCP/IP connectivity over Ether net or Point-to-Point Protocol connections to applications such as CMS Call Center, INTUITY AU DIX, and DCS.

IP Solutions

The capabilities and app lic ati on s of DEFIN I TY EC S are extended with the introduction of IP Solutions. IP Solutions supports audio/voice over a LAN or WAN, and it ensures that remote workers have access to communication system features from their PCs.

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.

for more

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.

Trunks

IP Solutions supports the following two types of trunks.

H.323

The Release 8 IP Interface in MedPro mode enables H.323 trunk service using IP connectivity between two DEFINITY ECS systems. The H.323 trunk groups can be

IP Trunk

The Release 8 IP Interface in IP Trunk mode allows for operation with existing Release 7 IP Interface circuit packs. It allows trunk groups to be defined as DS1 tie lines between DEFINITY ECS systems over a virtual private network.

IP SoftPhones

IP Solutions supports the following three SoftPhone applications.

Road-warrior Application

Enables use of the full DEFINITY ECS feature set from temporary remote locations anywhere in the world. The road-warrior app lic ati on consists of two s oftware applications running on a PC that is connected to DEFINITY ECS over an IP network. On DEFINITY ECS, the road-warrior application requires the C-LAN circuit pack for signaling and the Release 8 IP Interface running in MedPro mode for voice processing.

Telecommuter Application

Enables telecommuters to use the full DEFINITY ECS feature set from home. It consists of a PC and a telephone with separate connections to DEFINITY ECS. The PC provides the signaling pat h a nd the us er interface for call cont rol . A sta nda rd telephone provi des a high-quality voi ce pat h.

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.

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.

A s ystem wit h both Ho spitality and Hospitality Parameter Reduction enabled provides reduced system parameters that have a major impact on essential system features used by nonlodging customers. 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 . Suite Chec k-In vi a the Hun t-to feature w ill also "ch eck -out" all the extensions in the entire suite at the same 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.

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.

On ly comm ands that do not require user interaction after being entering on the command line (such as list, display, test) can be scheduled.

Concurrent User Sessions

In order to increase the efficiency of administration and maintenance functions, the DEFINITY ECS switch accommodates multiple concurrent administration and maintenance user sessions. Three or more devices (management terminals or operation support systems) can be connected to the switch to perform administration and/or maintenance tasks simultaneously. DEFINITY ECS supports eight concurrent administratio n and main tenanc e use rs — fiv e can perform con current admi nistr ati on, an d three can perform concurrent maintenance. The eight concurrent sessions can be in any combination of local and remote connections.

Security

Call Restrictions

By dialing an access code, Adm inistra tors and Atte ndants ha v e the abi lity to rest rict users from making or receiving certain types of calls. There are five restrictions:

■ Outward — User cannot place external calls.

■ Station-to-Station — User cannot place or receive internal calls.

■ Termination — User cannot receive any calls (except priority calls).

■ Toll — User cannot place toll calls but can place local calls.

■ Total — User can neither place nor receive any calls.

Security

The risks of unauthorized access can be minimized by combining the use of Remote Network Access with the following:

■ An unpublished remote access number

■ Deactivate unassigned barrier codes immediately

■ Change barrier codes frequently

■ Inform remote access users of their responsibility

■ Monitor call detail reports for unauthorized or abnormal calling patterns

Class of Restriction (COR)

Defines many different classes of call origination and termination privileges. DEFINITY ECS may have no restrictions, only a single COR, or may have as many classes of restrictions as necessa ry to effect the desi red restriction s. Many dif ferent ty pes of cl asses of restriction can be assigned to many types of facilities on the switch. For example, you can use a calling-party COR to prevent callers from accessing the public network.

Security Violation Notification (SVN)

Security Violation Notifica tio n (SVN) al lows you to set secu rity-rel ated parameters and to receive notification when the limits that you have established are violated. You can run reports related to both valid and invalid access attempts. You can also disable a login ID or remote access authorization that is associated with a security violation.

Station Security Codes

To provide additional security around the customer options the “init” login has been provided with additional security for the purpose of establishing an authentication procedure for attempts to remotely log into the system.

Calling/Connected Party Number (CPN) Restriction

Per Line CPN Restriction

Users may block the Calling Party Number when originating calls. For ISDN calls, the CPN Presentation Indicato r is encod ed acco rdingl y. For non-ISDN calls, goi ng to a pub lic network that supports the CPN Restriction feature, the network specific Feature Activation Code gets passed to the network for interpretation and activation.

If Per Line CPN Restriction is administered for a station, it will override any ISDN Trunk Group administration for sending Calling Party Number.

Per Call CPN Restriction

Users may indicate Calling Number privacy information. For ISDN calls, the CPN Presentation Indicator is encoded accordingly. For non-ISDN calls going to a public network that supports the CPN Restriction feature, the network specific Feature Activation C ode gets passed to the netw ork for interpretation a nd activ atio n of the de sired feature.

If Per Call CPN Restriction is activated for an outgoing call, it will override any Per Line CPN Restriction administration for the calling station, and will override any ISDN Trunk Group administration for sending Calling Number.

Restriction — Controlled

Allows an Attendant or telephone user, with console permission, to activate and deactivate for an individual telephone or a group of telephones, the following restrictions: outward, total, station-to-station, and termination restrictions.

Malicious Call Trace

Allows you to trace malicious calls. You define a group of terminal users who can notify others in the group when they receive a malicious call. These users can then retrieve information related to the call. Using this information, you can identify the malicious call source or provide in formation to personne l at an adjacent sy stem to comp lete the tr ace. It also allows you to record the malicious call.

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.

Provides a recorded announcement to a variety of types of calls: calls that cannot be completed as dialed, calls that have been in queue for an assigned interval, any calls whose destination is an announcement, or incoming calls to a user.

Music-on-Hold Access

Automatically provides music, silence, or tone to a caller. Music lets the caller know that the connection is still valid. Many different music options can be administered to accommodate different tenants on the DEFINITY ECS. See the Tenant Partitioning feature for more information.

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.

See also, ‘‘Music-on-Hold Access’’ on page 74.

Trunk Management

DEFINITY ECS supports a v ariety of inter faces to voic e and d ata netw orks. Trunks supply links between DEFINITY ECS, the public network, and other switches.

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.

DEFINITY ECS supports leased BRI connec tions throu gh the pub li c net wo rk, with a TN21 85 on each end of the leased connection. DEFINITY ECS will not, however, allow customers to administer both endpoints and trunks on the same TN556C circuit pack.

Call-by-Call Service Selection

Enables a single ISDN-PRI trunk group to carry calls to a variety of services, rather than requiring each trunk group to be dedicated to a specific service. It allows you to set up various voice and data services and features for a particular call.

Facility and Non-Facility Associated Signaling

Allows an ISDN-PRI DS1/E1 interface D-channel to carry signaling information for B-channels (voice or data). D-Channel Backup can also be administered to increase system reliability.

Wideband Switching

Provides the ability to dedicate 2 or more ISDN B-channels or DSO endpoints for applications that require large bandwidth. Certain applications, such as video conferencing and high-speed data transmission, require extra bandwidth and it becomes
