H5003 Compact PCM Mux
Product Overview
H5003 device is a new multi-function integrated service access device. It has two standard E1 transmission interfaces and provides 30 channels of voice and asynchronous data access,supporting many voice services including FXO, FXS, magneto, and 4-wire andRS232/RS422 asynchronous data. This device provides two E1 transmission directions and can work at 1+1 protection mode.
H5003 device can be used for point to point connection,it can also internetwork with our company’s PCM device, e.g.CO device H9MO-LMXE+.V2 and realize point to multipoint connecton.H5003 device can be equipped with monitoring system.Through monitoring system you can monitor the running status of device in real time and conduct fault location and reallocation of time slots. Main console is connected to monitored device through Ethernet interface, which is convenient to be added to network management of higher level.
