ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
The part of a carrier-multiplex terminal that performs the first step of modulation by multiplexing a group of channels into a higher bandwidth analog channel or higher bit-rate digital channel and, conversely, demultiplexes these aggregates back into individual channels.
Industry:Telecommunications
The parameter within a primitive that is the unit of information transferred to/from the upper layer or sublayer in a single interaction.
Industry:Telecommunications
The overhead added to the STS SPE (synchronous transport signal -- synchronous payload envelope) for transport purposes. Transport overhead consists of line and section overhead.
Industry:Telecommunications
The overall gain of a transmission circuit. Note 1: Net gain is measured by applying a test signal at an appropriate power level (see Note 5) at the input port of a circuit and measuring the power delivered at the output port. The net gain in dB is calculated by taking 10 times the logarithm of the ratio of the output power to the input power. Note 2: The net gain expressed in dB may be positive or negative. Note 3: If the net gain expressed in dB is negative, it is also called the "net loss. " Note 4: If the net gain is expressed as a ratio, and the ratio is less than unity, a net loss is indicated. Note 5: The test signal must be chosen so that its power level is within the usual operating range of the circuit being tested.
Industry:Telecommunications
The output power averaged over that cycle of an electromagnetic wave having the maximum peak value that can occur during transmission.
Industry:Telecommunications
The output of a clock. 2. A signal used to synchronize interconnected equipment.
Industry:Telecommunications
The OSI standard for the detailed architecture of the Network Layer. Note: Basically, it partitions the Network layer into subnetworks interconnected by convergence protocols (equivalent to internetworking protocols,) creating what is called a catenet or internet.
