What does PDH mean in TELECOM
PDH stands for Plesiochronous Digital Hierarchy. It is a telecommunications technology used to transmit large amounts of digital data over various types of physical media. PDH was created in the 1970s and was widely adopted initially by telecommunication providers as a way to transport large amounts of data across long distances. It was the first successful standard for transporting digital data, which allowed multiplexing, or combining multiple channels together into one circuit. Since its introduction, PDH has been largely replaced by Synchronous Digital Hierarchy (SDH) due to its higher capacity and better error correction capability.

Essential Questions and Answers on Plesiochronous Digital Hierarchy in "COMPUTING»TELECOM"
What is PDH?
PDH stands for Plesiochronous Digital Hierarchy. It is a telecommunications technology used to transmit large amounts of digital data over various types of physical media.
When was PDH introduced?
PDH was created in the 1970s and was widely adopted initially by telecommunication providers as a way to transport large amounts of data across long distances.
How does PDH work?
PDH allows multiplexing, or combining multiple channels together into one circuit which then transmits large amounts of digital data over various types of physical media.
Why has been SDH replacing PDH?
SDH has replaced PDH due to its higher capacity and better error correction capability.
What are some advantages of using PDH?
The main advantage of using PDH is that it allowed the transmission of large amounts of digital data successfully over long distances. Additionally, it allows for easier monitoring and fault localization compared with analog systems due to its ability to monitor each individual frame simultaneously instead of just one channel at a time.
Final Words:
PDH is an important telecommunications technology that revolutionized how digital data is transmitted over long distances by allowing companies like telecom providers to send larger volumes than ever before at much faster speeds — all while reducing costs associated with transmission lines and equipment needed for analog networks. Although largely replaced by SDH today, many organizations still use it due to its simplicity and reliability in delivering voice, video, and private leased lines when more advanced technologies are unavailable or unsuitable for their requirements.
