There are a number of different encoding methods used on T1 lines. Alternate Mark Inversion (AMI), Bipolar With 8-Bit Substitution (B8ZS), and High Density Bipolar Three Code (HDB3).

Huffman Coding is a method of shortening down messages sent from one computer to another so that it can be sent quicker.
using the color coding method
Yes, a linear combination of a low-frequency intelligence signal and a high-frequency carrier signal can be effective for radio transmission. This method, known as amplitude modulation (AM) or frequency modulation (FM), allows the low-frequency signal to be transmitted over longer distances by utilizing the high-frequency carrier wave. The carrier wave effectively "carries" the information, enabling it to be received and demodulated by appropriate receivers. This technique is fundamental in broadcasting and communication systems.
the binary numeral system
Amplitude modulation (AM) is a method used in telecommunications to vary the strength (amplitude) of a carrier signal in proportion to the waveform being sent. This modulation technique allows the transmission of audio or data signals through changes in the amplitude of the carrier signal. AM is commonly used in broadcast radio to carry audio signals.

Shannon-Fano coding offers several advantages, including simplicity and ease of implementation, making it accessible for basic data compression tasks. It effectively reduces the average length of encoded messages by assigning shorter codes to more frequent symbols, thus optimizing storage and transmission efficiency. Additionally, it is a prefix coding method, ensuring that no code is a prefix of another, which allows for unambiguous decoding. However, while it is straightforward, it may not yield the optimal compression compared to more advanced methods like Huffman coding.

describe the ancient method of transmitting information
ISDN (64k) is currently the slowest transmission method for broadband. Anything lower is deemed as "dial-up"(56k).
