Intelligent Peripheral Equipment

Using pulse code modulation (PCM), Intelligent Peripheral Equipment (IPE) converts analog signals to digital signals before switching is performed by the network. This conversion method samples the amplitude of the analog signal at a rate of twice the highest signal frequency, then converts the amplitude into a series of coded pulses. For telecommunications, the PCM-sampling frequency standard is 8 kHz.

Compressing-expanding (companding) PCM is a standard technique for using 8-bit words to efficiently represent the range of voice and data signals. Two standards for companding, A-Law and µ-Law, are recognized worldwide. IPE conforms to both standards; the standard required is selected through software.
