HJ-iAN155M Intelligent Access Platform is a multi-service STM-1 level SDH (Synchronous Digital Hierarchy) system.nOUSDIGITAL HIERARCHY) Optical Transmission System. Equipped with two STM-1 level optical ports, it enables multiplexing and transmission of services such as E1 and Ethernet based on GFP encapsulation. It supports full-time slot cross functionality, with convenient and flexible uplink/downlink circuits. It can serve as an uplink/downlink multiplexer or terminal multiplexer, to establish point-to-point, chain, and ring networks.
The equipment is widely used in scenarios with high reliability requirements and comprehensive functional needs, such as in telecommunications, mobile, unified communications, electricity, public security, military, expressways, banking, aviation, and other dedicated communication networks.
