HJ-iAN220 Intelligent Access Platform is a multi-service STM-1 level SDH (Synchronous Digital Hierarchy) system.(nOUSDIGITAL HIERARCHY) Optical Transmission System. Features dual STM-1 level optical ports for multiplexing and transmitting services such as E1 and Ethernet based on GFP encapsulation. Supports full-time slot cross-connect functionality, with convenient and flexible uplink/downlink circuits. Can be used as an uplink/downlink multiplexer or terminal multiplexer, to establish point-to-point, chain, and ring network equipment. Widely applicable in scenarios with high reliability and comprehensive functional requirements. Such as: telecommunications, mobile, Unicom, power, public security, military, expressways, banking, aviation, and other dedicated communication networks.
