详情描述

HJ-iAN220 Intelligent Access Platform MSAP is a multi-service SDH (Synchronous Digital Hierarchy) at STM-1 level.Our Digital Hierarchy (DH) optical transmission system features two STM-1 level optical ports, enabling multiplexing and transmission of services such as E1 and Ethernet based on GFP encapsulation. The device supports full-time slot cross functionality, with convenient and flexible uplink/downlink circuits, serving as both uplink/downlink multiplexers or terminal multiplexers to establish point-to-point, chain, or ring networks.
