SYSTEM FEATURES

 

The main features of the DIGITAL KEY BX, DIGITAL 400, and DIGITAL 1000 systems are listed below.  Access restriction Individual extensions may be restricted from accessing specific outside lines or groups of lines. Different access restrictions can be programmed for day and night service.

 

• ACD (Automatic Call Distribution) option - Using a sophisticated software program, the ACD program routes and distributes incoming calls among agents and ACD groups and provides supervisors with statistical reports (on the telephone display) of incoming call traffic and call processing. See Section 3, Automatic Call Distribution (ACD) Applications, for a detailed description of ACD.

 

• ACD I.Q. option - Using the data collected from the ACD program, ACD I.Q. (Automatic Call Distribution - Information Query) provides sophisticated statistical reports, histograms, and graphs that can be viewed on a personal computer screen, printed, stored, and retrieved. ACD I.Q. enables you to easily define the exact parameters desired for each report.

 

• Alphanumeric display of names - upper and lower case - Names can be assigned to extensions, page zones, trunks, trunk groups, hunt groups, and MDN groups so that when features are accessed or calls are placed, the name of the feature, source, or destination, rather than the facility's Directory Number or access code, is displayed. Names may have up to 16 letters and numbers, e.g. "Purchasing Line" or "Sally Lane SALES.” Names can be entered in the system program in upper or lower case, and they appear on the telephone display as they were programmed (for example, BROWN or Brown).

 

• Analog outside line volume control - The system audio signal amplification on individual analog outside lines can be programmed to suit the physical distance from the central office. Three amplification levels are possible.

 

• Analog station support - Telrad analog key telephones (manufactured after August 1987) are supported by the DIGITAL family of systems.

 

• ANI (Automated Number Identification) - The DIGITAL system receives the Caller ID information for calls coming in on T1 circuits (see Caller ID option, below).

 

• Announcement messages (9 messages) - administrative

 

 

• Announcement messages (50 messages) - ACD/hunt group*

 

• Announcer (SLT) - An external announcer, for playing pre-recorded messages, can be configured to answer outside calls to a Uniform Call Distribution (UCD) group.

 

• Answering position - An answering position to which calls, recalls, and dial attendant calls may be routed, can be configured in the system. The position may be used by a department secretary to answer the telephones in the department and to take calls that were left on hold, or the answering position may be used in addition to, or in place of, an attendant position.

 

For flexibility in processing incoming calls, calls to the answering position can be routed to up to eight Incoming Call Identifier (ICI) queues that arrive at different buttons on the answering position. This allows you to answer calls on each queue with a different greeting. When calls recall to the answering position, the recalling extension's name/number is displayed.

 

• Application generator - 
• Attendant console - Up to four attendant consoles may be connected to your DIGITAL KEY BX or DIGITAL 400 system, and up to 24 attendant consoles may be connected to your DIGITAL 1000 system. An attendant console position can be configures integrating up to four attendant consoles in the DIGITAL KEY BX or DIGITAL 400 systems and up to eight attendant consoles in the DIGITAL 1000 system (see Attendant Console Features, below).

 

• Automatic out-dial on system alarm - On detection of any alarm that affects system operation, DIGITAL systems can automatically dial the Service Center, via the modem, and transmit the details of the alarm.

 

• Automatic real-time self diagnostics and alarms - Through built-in diagnostics, the system continuously checks for faults in system operation. When faults are detected, alarms are sent instantly to the attendant console. The alarms are also stored in the system memory for analysis.

 

• Background music - System users have access to background music facilities that channels music to the station speaker while the station is idle. Up to four different background music
• sources can be connected to the DIGITAL KEY BX system, up to eight to the DIGITAL 400 system, and up to 12 to the DIGITAL 1000 system.

 

• Battery backup (memory) - During a power failure the system configuration data is maintained in battery-backed memory located in the memory module. The memory module can store configuration data for up to three years after being disconnected from the AC power source.

 

• Battery backup (system-wide) - To ensure continued system operation during power outage, the DIGITAL systems can be backed up by external batteries or by an Uninterruptible Power Supply (UPS).

 

• Behind PBX/CENTREX lines - Individual outside lines may be defined as extensions of a larger exchange. Special parameters, such as flash time, may be programmed to match the requirements of the larger exchange.

 

• Branch routing (networking digital systems) - Calls can be routed among different systems, branches, or departments of an organization at different locations with the press of a button. This feature takes advantage of the sophisticated networking capabilities of the DIGITAL family of systems, including DPNSS and QSIG corporate-wide networking (See DPNSS networking and QSIG networking under Private networking features, below).

 

• BRI (ISDN Basic Rate Interface) - The DIGITAL system supports ISDN Basic Rate Interface to both outside lines and internal lines. On internal BRI lines, each S-bus supports two TEIs (terminal equipment identifiers), and the DIGITAL system tracks calls to the appropriate TEI. This enables two incoming or outgoing calls to be handled simultaneously at the same DN.

 

·         Outside lines: The DIGITAL systems support ISDN Primary Rate Interface (PRI) outside lines, using the ETSI (Euro-ISDN), NT-DMS100, AT&T-4ESS or AT&T-5ESS standards, and Basic Rate Interface (BRI) outside lines, using the ETSI, NI1-DMS100, or NI1-5ESS standards, depending on public network support. The DIGITAL systems also support PRI and BRI ISDN supplementary services such as Call-By-Call Integrated Service Access (PRI only), Caller Line Presentation (CLIP), Caller Line Restriction (CLIR), and Direct Inward Dialing (DID), where supported by the public network. See ISDN Features, below.

 

·         Terminal lines: The DIGITAL system supports Basic Rate Interface for ISDN

terminals, using the ETSI (Euro-ISDN) or AT&T standards. This facilitates connection to the Internet, video conferencing, and communications with other ISDN terminals external to the DIGITAL system. It is possible to use both B channels on the BRI line individually or simultaneously for placing or receiving two internal or external calls on the same or on separate directory numbers (DNs). In addition to supporting the BRI bearer services, the following ISDN supplementary services are supported on the terminal lines: calling party identification presentation and restriction (CLIP and CLIR) and ETSI multiple subscriber number (MSN).

 

• Call Accounting Supervision - A call accounting supervision station can be designated.  From this station, you can monitor cost recording data and change whether cost data is recorded for individual stations.

 

• Caller ID option - A variety of Caller ID functions are available on incoming and outgoing calls on analog, ISDN, and T1 trunks. Where available from the local central office, for analog loop- and ground-start trunks, when a display station receives an incoming call, a message appears on the display, indicating the source of the incoming call. This requires a Caller ID interface box. Where supported by the central office and programmed in the DIGITAL system, for calls coming in on T1 and ISDN lines, the telephone number of the incoming caller appears on the telephone display. 

 

For T1 carriers caller identification is done via the Automated Number Identification (ANI) protocol. For ISDN carriers, this is done via the Caller Line Identification Presentation (CLIP) protocol. For ISDN carriers the system supports both CLIP and Caller Line Identification Restriction (CLIR) that can be programmed to operate on a call-by-call basis (see ISDN Features, below). The ANI caller identification feature for T1 can be programmed to show the calling party ID number on a trunk-by-trunk basis, where supported by the outside lines.

 

You can program the DIGITAL system to display either the incoming caller ID name or number.

 

In addition to sending the Caller ID number to the station display, the Caller ID interfaces with ImaGEN, ISMDR, and TelradLINK. A major advantage is call routing based on the incoming Caller ID number.  ImaGEN can use the Caller ID data to route incoming calls to a specific extension. This enables you to route a call directly to the person who should be processing it. Up to 1,000 Caller ID entries can be defined.

 

The Caller ID number data is forwarded to the ISMDR database. The Caller ID number data is also processed for calls made or received via the proprietary interface TelradLINK, TSAPI, and TAPI applications. With these applications based on the caller ID/ANI information, customer records can be sent as screen pops on your PC. You see the calling party's file while you receive the call, letting you review the file before speaking to the customer.

 

 

• Chaining digits under a private speed dial button - You may program a group or series of digits in a speed dial button string in order to invoke several actions, such as the activation of features or dialing, by pressing a single button. This enables direct one-button access to ImaGEN voice mail functions, such as:

 

·         Transfer to mailbox button

·         Password

·         Immediate answer to voice message.

 

·         Class Of Service (COS) - Extensions are assigned a Class of Service, through which access and restriction profiles to various system features and outside lines are programmed. The Class of Service may be different for Day and Night operation. Also, the DIGITAL systems may be programmed to provide five global (system-wide) COSs that may be accessed by any user with the appropriate password. Users with the appropriate password may also use their Class of Service at another station.

 

·         Configuration backup and restore - From either a local or remote location, a customer's configuration data can be uploaded from the system to a PC, for backing up onto disk, or restored (downloaded) from the PC to the system, to update a system configuration.

 

·         CTI (Computer Telephone Integration) applications - CTI applications, including Telephone Application Programming Interface (TAPI), Telephone Services Application Programming Interface (TSAPI), and the proprietary interface TelradLINK, enable integration of your DIGITAL systems and your personal computer.

 

·         Day and night service - For day and night modes, various call handling parameters for features (such as incoming ring routing and Class Of Service assignment) may be programmed. Day or night service mode is normally activated from the attendant position.

 

·         Dial-By-Name (Automated Attendant DBN)*

 

·         DID analysis - The DIGITAL systems’ Direct Inward Dialing (DID) analysis system allows the handling of DID numbers, received from the public exchange or the private network, which contain more than four digits. DID analysis also allows the processing of incoming DID calls directed to specific trunk groups, where supported by the public exchange.

 

·         Digital stations - The DIGITAL KEY BX, DIGITAL 400, and DIGITAL 1000 systems supports all seven models of Telrad Avanti family of digital telephone sets.

 

·         Direct In Lines (DIL) - Incoming calls on lines in the DIGITAL systems can be programmed to terminate directly at an extension, without being transferred from an attendant position.

 

·         Direct Inward Dialing (DID) - Since the DIGITAL systems have the ability to translate incoming dialed digits, they support Direct Inward Dialing from a Central Office. This enables outside callers to dial directly to a particular extension within the system, without the intervention of an attendant.  With the DIGITAL KEY BX system, you can store 200 number translations, with the DIGITAL 400 system, 400 numbers, and with the DIGITAL 1000 system 1500 numbers.

 

·         Direct Inward System Access (DISA) - An outside caller may dial into the system, access system features and, after dialing a security password, may even dial out of the system on the lines of the

·         DIGITAL system. A DID number can be routed to DISA. To prevent unauthorized calls, DISA may be deactivated during night service.

 

·         Direct Outward Dialing (DOD) - Outside calls, including long-distance and international calls, can be placed from any extension, depending on system programming, without the intervention of an attendant.

 

·         Directory assistance

 

·         Door Unit interface - An attendant and up to four designated stations can be alerted to a person at the front door by an audio warning, an indication on the station's display, and a programmed station DOOR UNIT button. They may then converse with the person, and release the door lock. The door unit has a distinctive ring so that it can be easily distinguished. Door units can be ring routed to different locations in day and night mode.

 

·         DSS Add-on unit - The Direct Station Select (DSS) Add-on unit provides one-touch dialing of up to 120 Directory Numbers and speed dial numbers and a visual Busy Lamp Field (BLF) indication for up to 120 extensions. Up to four units may be chained together and attached to any Avanti Attendant, Avanti 3025, Avanti 3020F, Avanti 3020H, Avanti 3015DF, Avanti 3015DH, or Avanti 3015H set. Alternatively you can shift between the four button maps on a single DSS Add-on unit. With the DIGITAL 400 and DIGITAL 1000 systems, up to eight button maps may be programmed with a maximum of four assigned to each DSS Add-on unit.  The DIGITAL 1000 system supports up to 48 DSS Add-on units, while the DIGITAL 400 and DIGITAL KEY BX support 16 and eight DSS units, respectively.

 

·         DTMF signaling to SLT ports - The DIGITAL systems provide DTMF signaling to SLT ports to enable operation of external equipment such as standalone Voice-Store-and-Forward machines, facsimile machines, etc. Elapsed time starter For each trunk or trunk group, you can define the delay after dial completion before the system starts timing the call.

 

·         Equal access support - You may choose a particular carrier for a call. If dialing via Least Cost Routing (LCR), the system selects the most economical carrier automatically. Different restriction routines can be defined for calls on different carriers.

 

·         Error message history file - Records of system errors, which generate system alarms and diagnostic messages, are stored in the Error Handling Unit (EHU) history file. This enables maintenance technicians to see, at a glance, the source and history of system malfunctions.

 

·         External bell interface - Incoming calls arriving in a noisy environment or at distant extensions can be programmed to ring at external bells. This ensures that all calls can be heard. Different ringing patterns can be programmed for day and night service. Up to four external bells may be configured in the DIGITAL KEY BX system, up to eight in the DIGTAL 400 system, and up to 48 in the DIGITAL 1000 system.

 

·         Flash type - You can define the default flash type for the system as either flash or signal. For individual calls you can override the default flash type. The preferred default depends on how your DIGITAL system is configured. 

 

·         Flexible Numbering Plan (FNP) - The code assigned to each extension, trunk, trunk group, or feature is flexible. The customer can select the code (up to four digits long) to be dialed when accessing each facility in the system. 

 

·         Half Private Trunk Groups (HPTG) - Half private trunks are regular private trunks that, for outgoing calls only, are grouped under a single Flexible Numbering Plan (FNP). In other words, they can be called directly from the outside but share one trunk group access code for placing outside calls. This allows stations with many buttons to receive the trunk

·         appearance and users of more simple stations to select outgoing trunks by using a single code.

 

·         Hearing aid compatible - All of the telephones available with the DIGITAL family of systems are hearing aid compatible.

 

·         Hunt groups - Groups of extensions, such as those within a company department, can be assigned a single Directory Number (DN). Calls placed or routed to that DN ring at all extensions within the group, in sequence, according to a pre-defined algorithm.

 

·         Hybrid key/PBX configuration - The DIGITAL systems can function as either key, PBX, or hybrid key/PBX systems, to suit any customer application requirements.

 

·         Incoming call routing - Incoming calls can be routed, per trunk or trunk group, to specific extensions or groups of extensions. Up to 16 extensions may be programmed to ring for an incoming call.

 

·         Intercom restriction - Four hierarchical intercom groups can be defined in which extensions belonging to a specific group can dial other extensions in the same, or in a lower intercom

·         group, but are restricted from dialing extensions belonging to intercom groups higher in the hierarchy.

 

·         Internal page zones - Up to eight internal page zones may be defined in the DIGITAL KEY BX and DIGITAL 400 systems, and up to 16 internal page zones may be defined in the DIGITAL 1000 system. Each extension may be granted or denied access to each page zone. Announcements to internal page zones may be routed  simultaneously to a public address system.

 

·         ISDN (Integrated Services Digital Network) - ISDN Primary Rate Interface to outside lines following ETSI (Euro-ISDN), NT-DMS100, and AT&T-4ESS and 5ESS standards is supported. Each ISDN Primary Rate Interface PRI24 card provides a 23B+D channel interface to the ISDN-based public switch network and the ability to access ISDN supplementary services (where supported by the public network).

 

Each ISDN Primary Rate Interface PRI30 card provides a 30B+D channel interface to the ISDN-based public switch network and the ability to access ISDN supplementary services (where supported by the public network). These services include Calling Line Identification Presentation, Calling Line Identification Restriction, Direct Inward Dialing, and Call-By-Call Integrated Service Access (see ISDN Features, below).

 

The DIGITAL system can generate busy, ring, and dial tones for ISDN PRI lines when these tones are not supplied by the CO. ISDN Basic Rate Interface to outside lines following ETSI, NI1-DMS100, or NI1-5ESS standards is supported. The BRT card provides four 2B+D channels for Basic Rate Interface to the ISDN-based public switch network and the ability to access ISDN supplementary services (where supported by the public network).

 

Basic Rate Interface is also provided for ISDN stations and terminals where ETSI (Euro) or AT&T ISDN protocol is supported. Each Basic Rate Interface station/terminal card provides four 2B+D channels.

 

• Least Cost Routing (LCR) - For each hour of the day and each day of the week, the system can select the least expensive available route and carrier for a given call, to maximize cost savings on long distance calls. Every installation can implement LCR in a unique way to meet its specific needs.

 

• Letter code feature access - The feature access codes programmed in the system reflect the feature name. For example, Background Music is operated by dialing [FEATURE] [B] [M] or [7] [2] [6] on the dialpad. You can access features without committing the feature code to memory, simply by remembering the feature name or abbreviation.

 

• Manager/secretary - A manager with a private secretary or several managers sharing one secretary can program all calls on their regular line to ring at the secretary's telephone when the secretary is at her desk and can program calls to ring directly at each manager's desk when the secretary is out of the office. The secretary's telephone can have a separate DN button for each manager so that she knows exactly whose call she is answering. Each manager can have selected internal and external callers reach her directly, by using a private DN (See Multiple station appearance, below).

 

• Memory cartridge - To enable simple configuration changes and system upgrades to the DIGITAL family of systems, all system programming is contained in a removable memory cartridge, which is attached to the main processor card.

 

• Modem (internal and external) - Online administration and maintenance procedures can be carried out from a remote site through a modem internal to the DIGITAL system or from a user supplied (external) modem. From the remote site, configurations can be backed up, restored, or changed, and the error message history file can be accessed. The internal modem is a module that snaps onto the Option card.

 

• Multiple appearance of DNs (MDN groups) - A call directed to a group of extensions (MDN groups), represented by a single Directory Number (DN), may ring at up to 16 extensions, and flash at an unlimited number of extensions, simultaneously. A call can ring at certain stations, and then after a programmed delay, ring at additional stations. Any extension where the call rings or has an appearance may answer the call by pressing the programmed MDN button. There can be multiple appearances of the same DN in an MDN group. With the DIGITAL KEY BX system, up to
• 250 MDN groups can be created, with the DIGITAL 400 system up to 400 groups can be created, and with the DIGITAL 1000 system up to 997 groups can be created.

 

• Multiple attendant positions - Up to four attendant positions may be configured in a DIGITAL KEY BX or DIGITAL 400 system to provide a high attendant to user ratio, efficient call traffic management, or up to four operative tenant exchanges. With the DIGITAL 1000 system, up to 24 attendant positions may be configured.

 

• Multiple station appearance (MSA) - MSA configuration (PBX) mode provides a second mode of operation to suit a variety of applications. Incoming calls for any extension can ring and flash, or just flash at a number of different extensions or, a call can ring at one station and have a delayed ring at another station. For example, if the secretary does not answer the call, it then rings the manager. You can program stations so that you may only place a call from a station when a DN button is available.

 

Therefore, you may assign the DNs of other stations to a telephone in an MSA group so that any station in the group can answer incoming calls being transferred to the group, or can make outgoing calls using another station's DN. You can have multiple appearances of the same DN in one MDN group and multiple DN hunting on the same station.

 

You can also assign a station a virtual DN to allow you to access an additional line. Each incoming or outgoing call is assigned to a button. Depending on which extension the call is for, a different LED lights so that the person answering the call knows exactly which extension is being called. This makes it easy to program the system so that a secretary can screen calls for one or more managers (see Manager/secretary, above) or for a group of employees, e.g. the members of a sales team. Incoming calls can be screened and forwarded, either to the specific person who should handle the call, or to the first available person from the group.

 

You can assign a DID line to one DN at each telephone (programmed with MSA) so that callers can be given a direct line to reach the person handling their business, while other calls can be sent to the same telephone using the other DNs appearing on it.

 

Call forwarding of internal or external calls can be programmed separately for each DN assigned to a station, or all the DNs can be forwarded to the same destination. 

 

All of the features described under Call Forwarding in the User Features, below, can be used with MSA.  In addition, the system can be programmed so that call forwarding for a DN can be done from any telephone on which the DN appears.

 

• Music on hold - Outside callers placed on hold can be connected to external music sources. Up to four different Music On Hold sources can be connected to the DIGITAL KEY BX system, up to eight can be connected to the DIGITAL 400 system, and up to 12 can be connected to the DIGITAL 1000 system.

 

• North American Numbering Plan - Each system in the DIGITAL family is compatible with the North American Numbering Plan.

 

• Off-premises extension (OPX) support - Through the SHD - single line extension card, the DIGITAL systems can connect to other telephone systems in the same organization, thereby enabling Direct Dialing from the local DIGITAL systems to any extension in the remote systems. The SHD interface can also be used to connect distant SLT extensions (OPXs) to the system.

 

• Option modules - Three option modules may be attached to each OCD to provide an internal modem; additional DTMF receivers; four ImaGEN voice mail ports, or external page zones and door units (MIM module); Telrad’s OAL link; the meet-me-conference option (Source1 module); or to enable the MPD redundancy feature in DIGITAL 1000 systems (Source 2 module).

 

• Page interface (external) - Up to eight external page or public address systems may be connected to the DIGITAL KEY BX andDIGITAL 400 systems, and up to 24 external page or public address systems may be connected to the DIGITAL 1000 system.

 

• PC attendant (option) - A detailed description of the PC attendant is provided, above, in Section 2, Terminal Units, under both Attendant and PC attendant and PC attendant features.

 

• Preferred connection - A station may be programmed to receive a pre-defined trunk or trunk group immediately when going offhook. This feature facilitates "Behind CENTREX" applications.

 

• PRI (ISDN Primary Rate Interface) - The DIGITAL system supports ISDN Primary Rate Interface outside lines and PRI ISDN supplementary services such as Call-By-Call Integrated Service Access, Caller Line Presentation (CLIP), Caller Line Restriction (CLIR), and Direct Inward Dialing (DID), where supported by the public network. The ETSI (Euro-ISDN), AT&T-4 ESS, AT&T-5ESS or NT1-DMS100 standards for Primary Rate Interfaces may be used, depending on public network support. The ISDN Primary

 

Rate Interface can also be used to connect DIGITAL systems in a network. See ISDN Features, below.

 

• Programming and Administration from a PC - The system can be programmed in two ways:

 

·         Offline: A system configuration can be prepared offline on an administration PC and stored on hard or floppy disk, without the PC being connected to the DIGITAL system.

 

·         Online: When the administration PC is connected online to a DIGITAL system, either locally, or remotely via modem, a complete configuration may be downloaded from the PC or backed up to the PC, modifications may be made to the system configuration and all maintenance procedures may be accessed.

 

• Recording cost or pulses - You can program the DIGITAL system to have the call cost displayed at the station and recorded for ISMDR and CDR (Call Detail Recording) reports in actual monetary cost or in the number of pulses metered (message units). Calculations are done for stations, private trunks, trunk groups, or hunt groups. For Multiple DN groups, the call cost can appear on the telephone display. You have the flexibility to decide for each DN whether or not to record the cost data.

 

• Recording call transfers - When calls are transferred, cost accounting data can be recorded separately for the time each party was involved in the conversation.

 

• Redundancy - The DIGITAL 1000 system has a system redundancy -- backup -- option to enable continued operation when there is a failure of the central processing unit (the MPD card). Also, in multiple-cabinet systems, if the power fails in the cabinet housing the MPD card, the system can provide back-up power to the MPD card.

 

• Central Processing Unit (CPU) backup: A second MPD card and a Source 2 module can be installed to provide the system with a backup main processor.

 

• MPD card power backup: If the power supply in the cabinet with the MPD (main processor) card fails, in a multiple-cabinet system, the power supply on the lower cabinet will provide power for the MPD card, keeping the system running.

 

• Remote reset - The system can be reset from a remote Service Center so that malfunctions requiring a reset can be dealt with quickly and effectively, without the need for a technician to visit the customer site.

 

• RS232 interface - The system features RJ45 ports that provide RS232 interface to peripheral equipment via the MPD, OCD, COL, CHL, COG, and RS232 cards and via the RS232 daughterboard that connects to the ONS and HONS cards. The MPD cards in the DIGITAL 400 and DIGITAL 1000 systems also have a 9-pin RS232 interface for connecting an external modem.

 

• Selective outside line ringing - Calls on outside lines ring at specified extensions, for specified periods of time.

 

Different ringing programs can be configured for day and night service.

 

• Single Line Telephone (SLT) support - On- and off-premise DTMF or rotary Single Line Telephones (Type 500 and 2500) are supported. The SLT ports can also be used to connect fax machines, announcers and Voice-Store-and-Forward devices to any of the DIGITAL systems.

 

• Software upgrades - When Telrad develops new software for the Avanti 3025, Avanti 3020F, Avanti 3020H, Avanti 3015DF, Avanti 3015DH, and Avanti 3015H telephone sets, the software can be downloaded to the telephones from a remote sight or from a PC connected to the MPD card in the system cabinet. The technician can specify that the download be done to these telephones system-wide, to all of a specific model of Avanti telephone, or to one specific telephone. This upgrade of the telephone software is quick and does not disrupt the whole operation of your office, since it is done without touching the telephones.

 

• Station Message Detail Recording (SMDR) - Details of all incoming or outgoing calls can be directed by the system to a printer or call accounting system. Both parameters of calls to be recorded (such as number of dialed digits or call duration) and transmission parameters of the SMDR device (such as baud rate and parity) can be programmed.

 

• Station self-test - Automatic station maintenance tests check the operation of the buttons on the telephone set and the telephone set hardware.

 

• System speed dial - Each class of service can access up to ten system speed dial groups. Each group can have up to 100 numbers. The DIGITAL KEY BX and DIGITAL 400 systems support two speed dial arrays, each with up to 10 system speed dial groups and 1700 (DIGITAL KEY BX) or 2700 (DIGITAL 400) system and personal speed dial numbers. The DIGITAL 1000 system support four speed dial arrays, each with up to 10 system speed dial groups and 2700 system and personal speed dial numbers.

• Tenant service - A number of features of the DIGITAL family of systems, such as call queues, call routing, access restriction, intercom restriction, etc., provide the system with tenant service capabilities. Four independent tenant groups may be configured, each with its own attendant position, extensions, and outside lines.

 

• T1/E1 carrier support - The digital trunk card provides the interface to a T1 carrier, the equivalent of 24 PCM trunks, or to an E1 carrier, the equivalent of 30 PCM trunks. Each one of the 24 T1 channels can be utilized as either a digital loop-start, ground-start, DID (Direct Inward Dialing), or tie line trunk. The system supports E1 protocols R2 or R2-MFC. Each one of the 30 E1 channels can be utilized as either a digital DID, DOD (Direct Outward Dialing), or tie line trunk. Multiple carriers may also be accommodated.

 

• Tie lines - The DIGITAL systems provide E&M signaling for tie lines. In conjunction with the DIGITAL systems' networking software, this allows private networking of DIGITAL systems, or interface to PBX tie lines. A network of DIGITAL systems can also be established using T1/E1 or ISDN PRI lines.

 

• Time setting station - One station in each system is defined to set the system time and date, as it appears on the station display and in the system.

 

• Toll restriction (TLR) - To control costs by restricting unauthorized use of office telephone facilities, calls initiated from certain extensions and dialed on certain outside lines or outside line groups may be restricted. The restrictions are based on 32 allow or deny toll restriction tables, in which specific dialed numbers (up to 31 digits long) are permitted or denied. For example, on a station-by station basis, you may restrict access to all long distance and international calls, or allow calls only locally and to specific long distance or international numbers (for example, customers or your organization's branch offices).

 

• Tone and pulse telephones - SLT extensions may be either impulse dial (type 500) or DTMF (type 2500). Dialing from pulse SLTs can be converted for outside dialing on DTMF trunks.

 

• TSAPI (Telephone Services Application Programming Interface)

 

• Trunk groups - Trunks defined in a group can be accessed by a single code or dedicated button on the Avanti telephone set. Up to ten trunk groups can be defined in the DIGITAL KEY BX system, up to 32 in the DIGITAL 400 system, and up to 64 in the DIGITAL 1000 system.

 

• Trunk signal amplification

 

• Trunks - The following trunk related parameters apply to the system.

 

·         Ground start: The DIGITAL system interfaces with ground-start outside lines via a COG or T1 card.

 

·         Loop start: The DIGITAL system interfaces with loop-start outside lines via a COL, CHL, COG, or T1/E1 card; in addition, in the DIGITAL KEY BX system, four ports are included on the MPD card.

 

·         ISDN Primary Rate Interface: The DIGITAL system interfaces with the public network ISDN Primary Rate Interface channels via a PRI24 and PRI30 cards, where supported by the public network (see ISDN Features, below).

 

·         ISDN Basic Rate Interface: The DIGITAL system interfaces with the public network ISDN Basic Rate Interface channels via BRT and BHT cards, where supported by the public network (see ISDN Features, below).

 

·         DPNSS interface: The DIGITAL system interfaces with DPNSS lines for networking DIGITAL switches, even with other vendor switches. QSIG interface: The DIGITAL system interfaces with QSIG lines to network a large number of switches supplied by different vendors.

 

·         Tie line interface: The DIGITAL system interfaces with tie lines via an EMD card or a T1/ E1 card.

 

·         Direct Inward Dial (DID): The DIGITAL system translates incoming dialed digits to enable direct inward dialing to specific extensions.

 

·         Open loop detection: If supported by the central office, the DIGITAL system recognizes an open loop state when a call has been placed, and it disconnects the line.

 

·         Pulse or DTMF: Each trunk in the DIGITAL system can be programmed as a pulse or DTMF trunk.

 

·         Pulse to DTMF conversion: When required by certain types of calls over a number of carriers, the DIGITAL system can dial (via LCR) both pulse and DTMF for a single subscriber number. Pulse-to-DTMF conversion of an outside line can also be included in all types of automatic dialing; that is, speed dial, redial, save/repeat, and automatic redial.

 

·         Tone detection: To enable automatic redial, auto dialer (scanner), and speed dial chaining, the DIGITAL system has call progress tone detectors that can recognize dial tone, busy tone, reorder tone, and ringback tone.

 

·         Battery reverse detection: When connected to an inter-office trunk, the DIGITAL system can detect reverse polarity caused by a closed loop.

 

• Uniform call distribution (UCD) - The volume of call traffic can be divided equally and fairly among system users to ensure uniform distribution of the call traffic load and quicker response for incoming callers.

 

• Wall mounting station - To free desk space and for ease of operation, all Avanti stations are wall-mountable.

 

ISDN FEATURES

 

The main DIGITAL systems' ISDN features are described below. Call-By-Call Integrated Service Access On a call-by-call basis, based on the number dialed, the system, after connecting to an ISDN channel, can request PRI ISDN services such as Outward Wide Area Telephone Service (OUTWATS), foreign exchange (FX), or tie lines from the public network. With call-by-call integrated service access, you have a great amount of flexibility. For each call, any ISDN channel can provide you with any of the services supported by the public switch. Therefore, you do not need the expense and trouble of a dedicated line for each service that you want to use.

 

• Caller Line Identification Presentation (CLIP) - The Avanti telephones with displays show the number of the calling party if the call is received over an ISDN line and the calling party has not blocked the display of the number. On outgoing calls on ISDN lines, your number can be displayed to the called party (if they have a caller identification facility). If your DIGITAL system is programmed to restrict caller line identification, you can override this restriction on a call-by-call basis, by entering a feature code. Also see the related feature Calling Line Identification Restriction, below. 

 

• Caller Line Identification Restriction (CLIR) - On outgoing calls on ISDN lines, you can prevent the display of your number to the called party. If your DIGITAL system is programmed to present caller line identification, you can block this presentation on a call-by-call basis, by entering a feature code. Also see the related feature Calling Line Identification Presentation, above.

 

• Direct Inward Dialing (DID) - The DIGITAL systems have the ability to translate dialed digits coming in on an ISDN line. They support Direct Inward Dialing from an exchange via ISDN lines. This enables outside callers, using the advantages of ISDN, to dial directly to a particular extension inthe DIGITAL system without the intervention of an attendant.

 

• Equal access - Where AT&T or Nortel ISDN standards are supported by the public network, the DIGITAL system will provide equal access for BRI outside lines and terminals.

 

• Multiple subscriber numbers - Where ETSI ISDN is supported by the public network, BRI station lines can be assigned multiple subscriber numbers for identifying the terminal for call charging and caller ID purposes.

 

• Video conferencing - Video conferences via ISDN lines can be established with an appropriately configured personal computer, receiving or calling out using two B channels of the BRS card.

 

 

PRIVATE NETWORK FEATURES

 

The main DIGITAL systems' private networking features are described below.

 

• Alternate routing - Networked DIGITAL systems provide alternate routes for internal and external calls to make the best use of all available tie, ISDN, DPNSS, QSIG, T1/E1, DID, and outside lines connected to the network.

 

Calls to destinations within the network can be routed along various tie routes throughout the branches of the private network or, if the tie lines are not available, along ISDN, DPNSS, QSIG, T1/E1, DID, or exchange outside lines. Calls to outside numbers are routed along the most efficient and economical route. For example, calls may be routed via the private network to the branch closest to the destination or routed directly to the public exchange, whichever is more practical.

 

• Back-to-back operation - To double the system capacity, two DIGITAL systems can be connected by customer-owned tie lines. With back-to-back operation, all of the outside lines in both systems are available to any of the extensions in either system.
