Description
Description
Video over E1 multiplexer can realize 1 channel video, 1 channel audio, 1channel RS485 over E1 transmission. It always use in pair. One transmitter, the other is receiver series.
It is ensured that any device with E1 interface, such as PBX, Mobile base station, SS7 signaling device and voice post system, can seamlessly connect to this video over E1 multiplexer. Video over E1, adopt H. 264 encode & decode technology, realize low data rate, high fidelity, real time video data transmitting and make that users pick up used E1 timeslots in fact by configurable feasible
