An indication provided to a source device indicating a signal failure condition at a sink device. Synonyms remote alarm indication, yellow alarm signal.
Industry:Telecommunications
An indication returned to a transmitting link terminating equipment (LTE) upon receipt of a line AIS (alarm indication signal) code or detection of an incoming line failure at the receiving LTE.
Industry:Telecommunications
An indication returned to a transmitting node (source) that an errored block has been detected at the receiving node (sink. )
Industry:Telecommunications
An indicator consisting of one or more digits which is defined in a given numbering plan and is used to indicate that the digits that follow are from a specific numbering plan which is different from the given number plan. Note: An escape code can be carried forward through the originating network and can be carried across internetwork and international boundaries.
Industry:Telecommunications
An indicator consisting of one or more digits, that allows the selection of different types of number formats (e.g., local, national or international,) transit networks and/or the service. Note 1: Prefixes are not part of the number and are not signaled over internetwork and international boundaries. Note 2: When prefixes are used, they are always entered by the user or by automatic calling equipment.
Industry:Telecommunications
An indicator of expected system reliability calculated on a statistical basis from the known failure rates of various components of the system. Note: MTBF is usually expressed in hours. 2. Of a system, over a long performance measurement period, the measurement period divided by the number of failures that have occurred during the measurement period. 3. For population of items, during a measurement period, the total functioning life of the population of items divided by the total number of failures within the population during the measurement period. Note 1: The total functioning life of the population may be calculated as the summation of the operating life of every item in the population over the measurement period. When computing the MTBF, any measure of operating life may be used, such as time, cycles, kilometers, or events. Note 2: For example, if a total of 1,000 events, such as data transfers, radio transmissions, or system boots, occurs in a population of items during a measurement period of 100 hours and there are a total of 10 failures among the entire population, the MTBF for each item is (1000) (100) /10 = 104 hours.
Industry:Telecommunications
