E1 and T1 Lines
E1 and T1 standards are basically introduced for voice communication.both are using TDM for frame formation.In this video, we will discuss the digital transmission, its advantages, and disadvantages.Basic concept about Modulation, Multiplexing, and PCM is already discussed.
Digital Transmission
Transmission of digital signals from one point to another point or from one system to another system.
The signal source may be analog but at the transmitter side, it must be converted to digital and at receiver side again into analog.
In digital transmission, a physical media is used between endpoints, as it could not travel in free space.
Why digital transmission
Less susceptible to interference caused by noise due to the discrete level.
Easy to detect errors due to the discrete level.
Easy to encrypt(Higher security).
Cheaper to implement due to advancement in digital electronics.
Digital signal is better suitable for multiplexing.
It is simpler to store a digital signal.
Disadvantages
Require precise time synchronization.
Require more bandwidth than simply transmitting the analog signal.
Additional encoding and decoding process is required for analog signal.
Not compatible with the older transmission system.
Modulation
Modulation is the process of changing the properties of one signal(carrier) with respect to another signal (Information).
PCM
In PCM(Pulse-code modulation) an analog signal is sampled and converted to a series of binary bits.
E1
E1 is European standard and its basic data rate is 2.048Mbps.It has 30 voice channel and 02 control channel.
T1
T1 is American standard and its basic data rate is 1.544Mbps.It has 24 voice channel and 01 framing bit.

Dear Sir,
Can we do Digital tx in free space if we increase the power of the signal?
Correct me if i am wrong: We can not do digital tx in free space because the equipment used for transmission for eg. transmitters or diodes, they always give low power digital output.
