HJ-iAN220 Intelligent Access Platform MSAP is an STM-1 level multi-service SDH (Synchronous Digital Hierarchy) optical transmission system. It features two STM-1 level group optical ports, enabling multiplexing and transmission of E1 and Ethernet services based on GFP encapsulation. The device supports full time-slot cross-connection functionality, with flexible and convenient upstream and downstream circuits, and can serve as an upstream/downstream multiplexer or terminal multiplexer to form point-to-point, chain, and ring networks.
1. All interface technical parameters comply with relevant international or domestic standards
2. Each interface has good overcurrent, overvoltage, and lightning protection. It passes ITU-T K.20 tests for lightning surge, power induction, and power contact tests; after circuit surge release, it can automatically recover
3. All device boards support hot-swapping
4. 19-inch 2U chassis with plug-in design structure, easy for expansion and maintenance; 1 main control slot, 5 service slots, and 1 power slot; 5 service slots can mix and match various voice boards, data boards, E1 boards, etc.
5. Provides 2 STM-1 rate level group optical interfaces, using SFP optical modules, supporting hot-swapping
6. 24 standard unbalanced E1 interfaces; 8 physically isolated 10/100M bandwidth Ethernet interfaces; 40 telephone voice interfaces
7. Auxiliary interfaces: Ethernet network management interface MNI; provides serial network management interface CONSOLE, interface type RJ45
8. Supports remote power-down detection (RPD) function and automatic laser shutdown (ALS) function
9. Supports local software online upgrade, easy to maintain
10. Modular power design; dual power supply modes AC220V and DC-48V
11. Comprehensive network management functions, real-time monitoring of various device operating statuses (optional)
12. Standard 2U chassis: (484x276x88)mm
