Excellent Features and Benefits of PCM Multiplexer
Pulse code modulation is the digital representation of an analog signal, which takes the sample of
amplitude of the analog signal at a regular interval. The PCM multiplexer is a fundamental
device for the digital communication system. It is mainly used for multiplexing the signals such
as image into a standard 2M interface through different interface cards, data, and voice and
point-to-point transmission. The functional features of pulse code modulation are supported in
brand channel and remote monitoring by auxiliary NMS; a voice interface supports the caller ID
display, provides 2M channels for point to point transmission and one 2M channel can set as
Basically, the PCM signal is a digital waveform that has minimum susceptible to the noise as
well as interference than the analog signals, because this digital waveform do not produce the
data perfectly as it is transmitted. This transmitted pulse is close enough to the expected value of
a binary code that can be reproduced into the actual binary one. This low noise susceptibility
allows the pulse code modulation signals to send farther than the analog signals without even the
signal information loss, degradation and distortion.
With the help of this modulation, you can increase the quality of reception as well as decrease
the height of the antenna. The pulse code modulation is also known as PCM. It is a process of
analog to digital signal coding process with continuous analog signal of quantization, variable
sampling and produces coding. The major benefits of using PCM multiplexer are producing a
good quality sound and widely used in many places such as electricity, government agencies,
public security, college network, military, marine, aviation and public or highway networks.
This PCM multiplexer is also featured in providing 30 channels of voice signals and also
supports the opposite pole charging as well as call indication.
