What are channel banks?

Banks

channels are communication devices used within telecommunications field. Their purpose is to connect multiple voice channels, which is achieved through voice digitization and multiplexing. They are important devices in terms of digital communication. This is transformed by a person's voice into a kilobite per second (KBPS) or Megabity per second (MBPS). They can be grouped into high -bit digital channels or can be easily reduced to individual. These devices received their name for the ability to contain enough energy to convert 24 individual channels from analog to digital format. Basically, they "bank" the power to be reused later.

There are quite several different types of channel banks from which the user will choose. Each of them is caps to tell the user what type of formatting is required to obtain the desired results. Types include the T1 circuit consisting of 24 channels, and the D4 K bankAnal that should always contain a DS-1 signal. The purpose of this signal is to ensure that the data is correctly formatted in accordance with the D4 format.

TRUNK D2, D3 and digital carrier (DCT) are other types of channel banks. Most telephone companies use them. D1 channel banks, which are also known as D1A, were first introduced in 1962. Other versions included D1b and D1C.

The first banks of D1a, B and C channels were all used almost seven bits of voice sample sample, one bit in each creature was in the code. These pieces of information were used to transmit signals such as the sound of the phone's ringing and heard the sound when the phone is off the hook.

D2 channel banks now use eight bits of time slot for coding analog signals. In addition, they have an increased density to 96 channels. On the other side of the D1 bank holds 72 channels. Both D3 and D4 can enable up to 144 kaMoods in their packages only in one single bay.
