- Commodity name: HJ-iAN155M
HJ-iAN155M 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 circuit switching, and can serve as an upstream/downstream circuit multiplexer or terminal multiplexer to build point-to-point, chain, and ring networks. The equipment 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.
