Overview

The IDM MSTP8200 Integrated Service Transmission Equipment is a new generation access-oriented optical-electrical integrated transmission equipment based on SDH technology, launched by Beijing Raytrans Digital Technology Co., Ltd. It is optimized for large-user access and provides access and transmission of multiple services. It meets the needs of users for broadband and narrowband fiber access, while also satisfying larger capacity requirements and providing more reliable communication protection. The IDM MSTP8200 is designed according to the functional modules defined in Recommendation G.783, providing complete service monitoring, access, protection, and network management functions inherent to SDH equipment, as well as Ethernet access functions required by MSTP equipment.

The IDM MSTP8200 Integrated Service Transmission Equipment is an STM-N level multi-service SDH (Synchronous Digital Hierarchy) optical transmission system with SDH and EOS technologies at its core, fully compliant with ITU-T standards. It provides STM-16/STM-4/STM-1 optical interfaces, Gigabit Ethernet ports based on EOS technology, E1 interfaces, and supports various 64K services including FXS/FXO, V.35/V.24, hotline, and magneto. It can also access video signals for convenient video surveillance system setup. The equipment features ITU-T G.813 standard network element timing, VC-12 cross-connect, and channel protection functions. Additionally, the IDM MSTP8200 can serve as an add-drop multiplexer or terminal multiplexer for building point-to-point, point-to-multipoint chain and ring transmission networks. The entire unit adopts a card-insertion structure, allowing configuration of different quantities and types of service cards as needed, reducing initial investment and facilitating future expansion, upgrades, and maintenance.
