The TCE-DH6816 series Telephone Multiplexer (4E1 16-Channel FXO / FXS) is a point-to-point optical transmission equipment developed on the basis of the ultra-large-scale PDH optical fiber transmission developed by our company. Has a sound alarm function, optional 1 to 4 100M wire speed Ethernet interface and 1 to 4 serial data interface. Device can be built-in SNMP module, stand-alone SNMP management. Electrical equipment for all-digital circuit, the whole work reliable, stable, low power consumption, high integration, small size, easy to install and maintain.
l Integrated circuit based on independent intellectual property rights;
l The whole machine is designed for veneer;
l Can monitor the alarm status of the peer;
l E1 interface complies with G.703 recommendations, using fully digital clock recovery and smooth phase lock technology;
l Provide two expansion interfaces, which can expand 1~4 asynchronous data, such as RS232 / RS485 / RS422 / Manchester code, etc .; or 1~8 switches and 1~4 E1(Therefore, up to 8 E1 channels on this device), 1~4 voice, or two/four-wire audio;
l Ethernet interface 10M / 100M, full / half duplex fully adaptive, VLAN support;
l Each Ethernet port supports Auto-MDIX (cross / straight connection adaptation);
l 1-16 voice access, support for caller ID function;
l Support each site's mutual release number function;
l Voice port support FXO port and FXS port, FXO port and program-controlled switch docking, FXS port and the user's phone connected;
l Desktop equipment can support independent SNMP network management, and support optical network management level connected (optional);
l Can detect the loss of optical signals for the remote device off or fiber fails;
l Can monitor the local temperature and the local voltage;
l Can monitor the voltage and temperature of the remote device and set the temperature alarm threshold;
l A variety of power options: AC220V, DC-48V / DC24V, etc .;
l No relay transmission distance greater than 2 ~ 120 km.
