Overview
Product Introduction: HS-DXCON202 Ethernet Digital Crossover Device can extract several consecutive time slots from the upstream ITU-T G.703 standard E1 interface as Ethernet services, and maintain direct communication between upstream E1 and downstream E1 in the remaining time slots; Multiple devices of this type or other related devices can be cascaded, with each node occupying several time slots, and ultimately converged onto a 2M time plane for transmission. When the traffic volume is small, it can effectively improve the utilization rate of E1. The device is suitable for multiplexing and transmitting multiple services between spatially separated nodes on the same E1, which can effectively reduce the number of devices and simplify the network structure. It is suitable for transmitting monitoring information from multiple nodes with small traffic volume. The device comes with a Console port and supports super terminal control of the device.
