MSTP and SDH Equipment

Hello!

SDH and MSTP are not two different technologies. MSTP is developed on the basis of SDH. The SDH equipment supports only client-side access to the PDH and SDH service network. The MSTP equipment supports Ethernet services, ATM services, PCM services, and more powerful redundancy protection functions besides PDH and SDH services. Therefore, the Ethernet services, ATM services, PCM services, and more powerful redundancy protection functions supported by the MSTP equipment are not supported by the traditional SDH equipment.

Thank you!

Dear friend!
As Faysalji said, MSTP equipment provides several more types of services than SDH equipment. Therefore, Ethernet boards, ATM boards, and PCM boards are required.   In addition, the MSTP equipment is also installed with a more powerful SCC unit, which manages and controls all tributary boards.
Thank you!
