| Configuration and Features |
- The MSM2500 device can be mounted with two systems in one rack, and one system consists of one signal self M/B to accommodate 2.5G low-speed signals, and consists of three large functional blocks.
- High-speed part: It connects STM-16 optical transmission and reception lines, processes overhead signals, generates system synchronous clocks that meet ETSI and ITU-T Bellcore standards, connects low-speed signals, adds/drops, DNI and HUB functions, and multiplexes/demultiplexes dependent signals according to the synchronous structure (SDH) selection recommended by ITU-T G707.
- Low speed part : PDH (DS-1E, DS-3) signal connection function, SDH (STM-1, STM-4) signal connection function, signal processing by connecting to high speed part according to synchronous structure selection, 1+1 and 1:n structure can be set for each dependent signal module according to user selection, and PDH signal switching part is signal processing by the operator's connection connection part. In particular, the multiplexing structure of DS-1E and DS-3 signals can be selected in AU-3 or AU-4 mode according to the operator's selection.
- Monitoring control unit: It has monitoring control and switching (OAM&P) function of the entire system, convenient remote control function through DCC and network management function through Q-LAN, and has a 1+1 dual structure.
