The PDH interface standard is not uniform,there is 1.5Mbps and 2Mbps. The PDH system have not strong management function.
Pyruvate dehydrogenase (PDH) are regulated by pyruvate dehydrogenase kinase (PDH-K) and PDH phosphatase. PDH-K effect on PDH is that it will inactivate PDH and PDH phosphatase will reactivate PDH. PDH-K is regulated by energy surpluses (ATP, NADH) and energy deficits (ADP, NAD). So when there is an energy surplus, PDH-K will inhibit PDH, and vice versa. PDH phosphatase will activate PDH and is upregulated by magnesium and calcium.
PDH (Plesiochronous Digital Hierarchy) communication has several disadvantages, including its complexity in synchronization, which can lead to difficulties in maintaining data integrity. Additionally, PDH systems are less flexible compared to newer technologies like SDH (Synchronous Digital Hierarchy), making upgrades and integrations with modern networks challenging. The limited bandwidth options and the inability to efficiently handle data traffic also hinder its performance in high-demand scenarios. Lastly, troubleshooting and maintenance can be cumbersome due to the proprietary nature of many PDH systems.
- Bit justification is needed in PDH - No would standards available at optical interface in PDH - line rates are not standard - Interfacing problem at multivendor equipment - PDH supports 16E1s and SDH supports 63E1s

PDH stands for Plesiochronous Digital Hierarchy. It is a technology that is used in telecommunications networks to send large quantities of data over digital transport equipment, like fiber optic and microwave radio systems.
I believe the word you are looking for is "meadow" (lark's home) - not "teadow"." pdh
ask miss roden or mr bottalico, this pdh assignment sucks
