A network utility that consists of a name assigned by the originating network for each established or partially established virtual call. Note: When a call identifier is used in conjunction with the calling data terminal equipment (DTE) address, the call identifier uniquely identifies the virtual call.
Industry:Telecommunications
A network, of fixed resistors, that attenuates signals by a fixed amount with negligible distortion. Note: The resistive network is called an attenuator if the resistance is adjustable.

Industry:Telecommunications
A network, or circuit, that produces an output waveform that is the time derivative of the input waveform. Note: Differentiating networks are used in signal processing, such as for producing short timing pulses from square waves.
Industry:Telecommunications
A network-provided service feature in which a call originator may, without operator assistance, call any other user outside the local calling area. Note 1: DDD extends beyond the boundaries of national public telephone networks. Note 2: DDD requires more digits in the number dialed than are required for calling within the local area.
Industry:Telecommunications
A network-provided service feature in which a priority dial tone is furnished. Note 1: Essential service is typically provided to fewer than 10 % of network users. Note 2: Essential service is recommended for use in conjunction with NS/EP telecommunications services. Synonym critical service.
Industry:Telecommunications
A network-provided service feature in which a user is provided with a virtual circuit. Note: Virtual circuit capability is not necessarily limited to packet mode transmission. For example, an analog signal may be converted to a digital signal and then be routed over the network via any available route.
Industry:Telecommunications
A network-provided service feature in which a user pays a higher flat rate to obtain wider geographical coverage without paying per-call charges for calls within the wider area.
Industry:Telecommunications
A network-provided service feature in which the network notifies a called terminal of the address from which the call has originated.
