DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Glossary and abbreviations 1627 GL appearance A software process that is associated with an extension and whose purpose is to supervise a call. An extension can have multiple appearances. Also called call appearance, line appearance, and occurrence. See also call appearance. application An adjunct that requests and receives ASAI services or capabilities. One or more applications can reside on a single adjunct. However, the switch cannot distinguish among several applications residing on the same adjunct and treats the adjunct, and all resident applications, as a single application. The terms application and adjunct are used interchangeably throughout this document. applications processor A micro-computer based, program controlled computer providing application services for the DEFINITY switch. The processor is used with several user-controlled applications such as traffic analysis and electronic documentation. application service element See capability group . architecture The organizational structure of a system, including hardware and software. ARS See Automatic Route Selection (ARS). ASAI See Adjunct-Switch Application Interface (ASAI) ASCII (American Standard Code for Information Interchange) The standard code for representing characters in digital form. Each character is represented by an 8-bit code (including parity bit). association A communication channel between adjunct and switch for messaging purposes. An active association is one that applies to an existing call on the switch or to an extension on the call. asynchronous data transmission A method of transmitting data in which each character is preceded by a start bit and followed by a stop bit, thus permitting data characters to be transmitted at irregular intervals. This type transmission is advantageous when transmission is not regular (characters typed at a keyboard). Also called asynchronous transmission. See also synchronous data transmission . asynchronous data unit (ADU) A device that allows direct connection between RS-232C equipment and a digital switch. Asynchronous Transfer Mode (ATM) A packet-like switching technology in which data is transmitted in fixed-size (53-byte) cells. ATM provides high-speed access for data communication in LAN, campus, and WAN environments. AT B See All trunks busy (ATB). AT D See Attention dial (ATD). attendant A person at a console who provides personalized service for incoming callers and voice-services users by per- forming switching and signaling operations. See also attendant console .
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Glossary and abbreviations 1628 GL AT M See Asynchronous Transfer Mode (ATM). attendant console The workstation used by an attendant. The attendant console allows the attendant to originate a call, answer an incoming call, transfer a call to another extension or trunk, put a call on hold, and remove a call from hold. Attendants using the console can also manage and monitor some system operations. Also called console. See also attendant . Attention dial (ATD) A command in the Hayes modem command set for asynchronous modems. Audio Information Exchange (AUDIX) A fully integrated voice-mail system. Can be used with a variety of communications systems to provide call-history data, such as subscriber identification and reason for redirection. AUDIX See Audio Information Exchange (AUDIX). auto-in trunk group Trunk group for which the CO processes all of the digits for an incoming call. When a CO seizes a trunk from an auto-in trunk group, the switch automatically connects the trunk to the destination — typically an ACD split where, if no agents are available, the call goes into a queue in which callers are answered in the order in which they arrive. Auto-In Work mode One of four agent work modes: the mode in which an agent is ready to process another call as soon as the cur- rent call is completed. Automatic Alternate Routing (AAR) A feature that routes calls to other than the first-choice route when facilities are unavailable.*** Automatic Callback (ACB) A feature that enables internal callers, upon reaching a busy extension, to have the system automatically con- nect and ring both parties when the called party becomes available. Automatic Call Distribution (ACD) A feature that answers calls, and then, depending on administered instructions, delivers messages appropriate for the caller and routes the call to an agent when one becomes available. Automatic Call Distribution (ACD) split A method of routing calls of a similar type among agents in a call center. Also, a group of extensions that are staffed by agents trained to handle a certain type of incoming call. Automatic calling unit (ACU) A device that places a telephone call. Automatic Circuit Assurance (ACA) A feature that tracks calls of unusual duration to facilitate troubleshooting. A high number of very short calls or a low number of very long calls may signify a faulty trunk. Automatic Number Identification (ANI) Representation of the calling number, for display or for further use to access information about the caller. automatic restoration A service that restores disrupted connections between access endpoints (nonsignaling trunks) and data end- points (devices that connect the switch to data terminal and/or communications equipment). Restoration is done within seconds of a service disruption so that critical data applications can remain operational.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Glossary and abbreviations 1629 GL Automatic Route Selection (ARS) A feature that allows the system to automatically choose the least-cost way to send a toll call. automatic trunk A trunk that does not require addressing information because the destination is predetermined. A request for service on the trunk, called a seizure, is sufficient to route the call. The normal destination of an automatic trunk is the communications-system attendant group. Also called automatic incoming trunk and automatic tie trunk. AUX Auxiliary auxiliary equipment Equipment used for optional system features, such as Loudspeaker Paging and Music-on-Hold. auxiliary trunk A trunk used to connect auxiliary equipment, such as radio-paging equipment, to a communications system. Aux-Work mode A work mode in which agents are unavailable to receive ACD calls. Agents enter Aux-Work mode when involved in non-ACD activities such as taking a break, going to lunch, or placing an outgoing call. AV D Alternate voice/data AWO H See Administration Without Hardware (AWOH). AWG American Wire Gauge AWT Average work time B B8ZS Bipolar Eight Zero Substitution. bandwidth The difference, expressed in hertz, between the defined highest and lowest frequencies in a range. barrier code A security code used with the Remote Access feature to prevent unauthorized access to the system. Basic Rate Interface (BRI) A standard ISDN frame format that specifies the protocol used between two or more communications sys- tems. BRI runs at 192 Mbps and provides two 64-kbps B-channels (voice and data) and one 16-kbps D-chan- nel (signaling). The D-channel connects, monitors, and disconnects all calls. It also can carry low-speed packet data at 9.6 kbps. baud A unit of transmission rate equal to the number of signal events per second. See also bit rate and bits per sec- ond (bps).
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Glossary and abbreviations 1630 GL BCC See Bearer capability class (BCC) . BCMS Basic Call Management System BCT See business communications terminal (BCT). Bearer capability class (BCC) Code that identifies the type of a call (for example, voice and different types of data). Determination of BCC is based on the caller’s characteristics for non-ISDN endpoints and on the Bearer Capability and Low-Layer Compatibility Information Elements of an ISDN endpoint. Current BCCs are 0 (voice-grade data and voice), 1 (DMI mode 1, 56 kbps data transmission), 2 (DMI mode 2, synchronous/asynchronous data transmission up to 19.2 kbps) 3 (DMI mode 3, 64 kbps circuit/packet data transmission), 4 (DMI mode 0, 64 kbps synchro- nous data), 5 (temporary signaling connection, and 6 (wideband call, 128–1984 kbps synchronous data). BER Bit error rate BHCC Busy-hour call completions bit (binary digit) One unit of information in binary notation, having two possible values: 0 or 1. bits per second (bps) The number of binary units of information that are transmitted or received per second. See also baud and bit rate. bit rate The speed at which bits are transmitted, usually expressed in bits per second. Also called data rate. See also baud and bits per second (bps). BLF Busy Lamp Field BN Billing number BOS Bit-oriented signaling BPN Billed-party number bps See bits per second (bps). bridge (bridging) The appearance of a voice terminal’s extension at one or more other voice terminals. BRI The ISDN Basic Rate Interface specification. bridged appearance A call appearance on a voice terminal that matches a call appearance on another voice terminal for the dura- tion of a call.

BX.25 A version of the CCITT X.25 protocol for data communications. BX.25 adds a fourth level to the standard X.25 interface. This uppermost level combines levels 4, 5, and 6 of the ISO reference model. bypass tie trunks A 1-way, outgoing tie trunk from a tandem switch to a main switch in an ETN. Bypass tie trunks, provided in limited quantities, are used as a last-choice route when all trunks to another tandem switch are busy. Bypass tie trunks are used only if all applicable intertandem trunks are busy. byte A sequence of (usually eight) bits processed together. C cabinet Housing for racks, shelves, or carriers that hold electronic equipment. cable Physical connection between two pieces of equipment (for example, data terminal and modem) or between a piece of equipment and a termination field. cable connector A jack (female) or plug (male) on the end of a cable.

Call Detail Recording utility (CDRU) Software that collects, stores, optionally filters, and outputs call-detail records. Call Management System (CMS) An application, running on an adjunct processor, that collects information from an ACD unit. CMS enables customers to monitor and manage telemarketing centers by generating reports on the status of agents, splits, trunks, trunk groups, vectors, and VDNs, and enables customers to partially administer the ACD feature for a communications system. call-reference value (CRV) An identifier present in ISDN messages that associates a related sequence of messages. In ASAI, CRVs dis- tinguish between associations. call vector A set of up to 15 vector commands to be performed for an incoming or internal call. callback call A call that automatically returns to a voice-terminal user who activated the Automatic Callback or Ringback Queuing feature. call-waiting ringback tone A low-pitched tone identical to ringback tone except that the tone decreases in the last 0.2 seconds (in the United States). Call-waiting ringback tone notifies the attendant that the Attendant Call Waiting feature is activated and that the called party is aware of the waiting call. Tones in international countries may sound dif- ferent. call work code A number, up to 16 digits, entered by ACD agents to record the occurrence of customer-defined events (such as account codes, social security numbers, or phone numbers) on ACD calls. CAMA Centralized Automatic Message Accounting carrier An enclosed shelf containing vertical slots that hold circuit packs. carried load The amount of traffic served by traffic-sensitive facilities during a given interval. CARR-POW Carrier Port and Power Unit for AC Powered Systems CAS Centralized Attendant Service or Call Accounting System capability A request or indication of an operation. For example, Third Party Make Call is a request for setting up a call; event report is an indication that an event has occurred.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Glossary and abbreviations 1633 GL capability group Set of capabilities, determined by switch administration, that can be requested by an application. Capability groups denote association types. For example, Call Control is a type of association that allows certain func- tions (the ones in the capability group) to be performed over this type of association. Also referred to as administration groups or application service elements (ASEs). CA-TSC Call-Associated Temporary Signaling Connection cause value A value is returned in response to requests or in event reports when a denial or unexpected condition occurs. ASAI cause values fall into two coding standards: Coding Standard 0 includes any cause values that are part of AT&T and CCITT ISDN specifications; Coding standard 3 includes any other ASAI cause values. This document uses a notation for cause value where the coding standard for the cause is given first, then a slash, then the cause value. Example: CS0/100 is coding standard 0, cause value 100. CBC Call-by-call or coupled bonding conductor CC Country code CCIS Common-Channel Interoffice Signaling CCITT CCITT (Comitte Consultatif International Telephonique et Telegraphique), now called International Telecom- munications Union (ITU). See International Telecommunications Union (ITU) . CCMS Control-Channel Message Set CCS See capability. CCS or hundred call seconds A unit of call traffic. Call traffic for a facility is scanned every 100 seconds. If the facility is busy, it is assumed to have been busy for the entire scan interval. There are 3600 seconds per hour. The Roman numeral for 100 is the capital letter C. The abbreviation for call seconds is CS. Therefore, 100 call seconds is abbrevi- ated CCS. If a facility is busy for an entire hour, then it is said to have been busy for 36 CCS. See also Erlang .
