Answer-seizure Ratio
The answer-seizure ratio (ASR) is the percentage of telephone calls which are answered, a measure of network qualityITU SG2 Recommendation E.411: International network management - Operational guidance. and call success rates in telecommunications. Definition In telecommunication an attempted call is termed a ''seizure''; the answer-seizure ratio is defined as 100 times the ratio of answered calls, i.e. the number of seizures resulting in an ''answer'' signal, to the total number of seizures: ASR = 100 \ \frac Busy signals and other call rejections by the telephone network count as call failures. However, the inclusion in the ASR accounting of some failed calls varies in practical applications. This makes the ASR highly dependent on end-user action. Low answer-seizure ratios may be caused by far-end switch congestion, not answering by called parties and busy destination circuits.

Telecommunications
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Network Effectiveness Ratio
In telecommunications, the Network Effectiveness Ratio (NER) measures the ability of a network to deliver a call to the called terminal. Busy signals and other call failure due to user behaviour are counted as "successful call delivery" for NER calculation purposes. Unlike ASR, NER excludes the effects of customer and terminal behaviour. NER is a measure of network quality defined by the ITU.ITU-T Recommendation E.425 NER = 100 \ \frac In general, the Network Effective Ratio is used to calculate the effectiveness of the internal interconnect routes.

Call Detail Record
A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transactions (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration, completion status, source number, and destination number. It is the automated equivalent of the paper toll tickets that were written and timed by operators for long-distance calls in a manual telephone exchange. CDR contents A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Average Call Duration
The average call duration (ACD) is a measurement in telecommunications that reflects an average length of telephone calls transmitted on telecommunication networks. The measurement is typically based on the reporting by telecommunication equipment via call detail records. Samples are collected to determine traffic demand and forecast call volumes, serving also as a tool for infrastructure monitoring of switches and cables. Depending on the type of call being made, ACD can be used as a proxy measure of call quality.
