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.

Features

l  Support ADM or TM modes, the ADM mode supports two transmission direction, and TM provides 1+ 1 transmission protection

l  2 standardE1 interfaces, complying with ITU-T G.703 recommendation

l  Voice interface supports 30 channels of two-wire phone (FXO/FXS/Hotline/2100Hz Magneto), or 22 channels of two-wire phone and 8 channels of four-wire voice and 4 channels of E/M signaling and complies with ITU-TG.711 and G.713 recommendations

l  RS232 asynchronous data support 30 channels at maximum, RS422 asynchronous data support 8 channels at m aximum

l  A abundan tof LEDs on the panel for convenient operation and fault diagnosis

l  ADM supports 64kbit/s monitoring function, and each E1 can select a 64kbit/s time slot as monitoring channel

l  19 inches1U standard chassis, which is small volume and save space

l  -48V DC power supply, or -48V DC/100~240V wide-range AC dual mode power supply

l  Support bottom program and FPGA program online update.
