HJ-iAN220 Intelligent Access Platform 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 services such as E1 and Ethernet based on GFP encapsulation. It supports full time-slot cross-connect functionality, with flexible and convenient upstream and downstream circuits, and can serve as an upstream/downstream multiplexer or terminal multiplexer to build point-to-point, chain, and ring network devices. It is widely used in scenarios requiring high reliability and comprehensive functionality, such as telecommunications, mobile, Unicom, power, public security, military, highways, banking, aviation, and other dedicated communication networks.
1. All interface technical parameters comply with relevant international or domestic standards
2. All types of boards support hot-swapping functionality
3. 19-inch 2U chassis, plug-in design, easy expansion and maintenance; 1 main control slot, 5 service slots, and 1 power slot
Transmission interface: provides 2 STM-1 rate level group optical interfaces, using SFP optical modules, supporting hot-swapping
Service interface: 24 standard E1 interfaces (G.703), unbalanced or balanced interfaces optional; 8 physically isolated 10/100M bandwidth Ethernet interfaces; 40 telephone interfaces.
