- Commodity name: HJ-A2030
The HJ-A2030 series integrated access device adopts internationally advanced integrated circuits, programmable logic circuits, and high-speed microprocessor design. The device integrates optical transmission, PCM multiplexing, and time-slot cross-connection technologies, using cross-connection technology to achieve dynamic allocation of time-slot resources, thereby improving the utilization of line resources. It features a plug-in card design with 16 general-purpose service slots, allowing arbitrary configuration of various functional service cards according to user needs. The service options are very flexible. The transmission medium is E1 channels (single E1/4E1 bundling) or optical fiber channels. The standard capacity is ≤128 lines. It provides a high-quality, economical, and reliable solution for large-capacity access.
