- Commodity name: HJ-A2020
The HJ-A2020 series integrated access device adopts internationally advanced integrated circuits, programmable logic circuits, and high-speed microprocessor design. It is a comprehensive access device that integrates optical transmission, PCM multiplexing, and time-slot cross-connection technologies. Using cross-connection technology, it achieves dynamic allocation of time-slot resources, thereby improving the utilization of line resources. The plug-in card design provides 6 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 ≤48 lines. It provides a high-quality, economical, and reliable solution for medium and small capacity access.
