- Commodity name: HJ-iAN220
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 E1 and Ethernet services 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.
