General information:

4E1+30channel phone fiber optical Mux, is a point-to-point optical

transmission equipment developed based on ultra large scale integrated circuit. It has perfect alarm function, 1~4 100M rate of ethernet port and 1~4 channel asynchronous data port. SNMP inside to realize SNMP management individual. The device's electronic part is total digital circuit, to assure working steady, low power consumption, high integration and easy maintain.

Product character: (1) based on self-independent knowledge circuit;

Veneer design;

Provide control remote alarm status;

E1 interface accord with G.703, adopt digital clock reset and flat lock technique;

Provide 2 extended ports which support 1~4 channel asynchronous data, eg, RS232/RS485/Manchester code; or 1~8channel switch value, 1~4 E1(so, the maximum E1 channel can reach 8), 1~4 channel voices, or 2/4 line audio;

Ethernet interface 10/100M auto adapted, full/semi duplex auto adapted, can be divided VLAN;

1~30 channel voice, support call-in show function;

Support each point call each other;

Voice support FXO&FXS, FXO connects to PBX, FXS connects to user's phone set;

Desktop device support independent SNMP, and link control for option;

Support detecting optical signal loss caused by remote device's turn off or fiber's break down;

Inspect local device's temperature and voltage;

Inspect remote device's temperature and voltage and set temperature alarming value;

Transmission distance can reach 2~120km without relay;

Multiple power supply type for option: AC220V, DC-48V/DC24V etc;
