u16 channel Voice+4*E1+4*FE (Fiber 1+1 backp, E1 1+1 backup) over Optic Fiber or E1 PCM Multiplexer FCP-020213-8

This series of products is a two-in-one product of point-to-point optical transmission and E1 PCM multiplexing equipment developed based on the dedicated very large-scale integrated circuit developed by the company.

This product provides 16*voice interfaces + 4*E1 interfaces + 4*100M Ethernet interfaces (100M bandwidth) during optical fiber transmission. It provides 16*voice interfaces + 4*100M Ethernet interfaces (1M bandwidth) during E1 transmission. ); Fiber can be backed up in 1+1 mode, and E1 can be backed up in 1+1 mode. The priority is primary fiber > backup fiber > primary E1 > backup fiber.

● Integrated circuits based on independent intellectual property rights;

● During optical fiber transmission, it provides 16 voice interfaces + 4 E1 interfaces + 4 100M Ethernet interfaces (100M bandwidth); during E1 transmission, it provides 16 voice interfaces + 4 100M Ethernet interfaces (1M bandwidth);

● Optical fiber can be backed up in 1+1, and E1 can be backed up in 1+1. The priority is primary fiber > backup fiber > primary E1 > backup fiber. When the two fiber ports are not connected, the transmission port switches from fiber to E1 interface;

● The E1 interface complies with G.703 recommendations and adopts fully digital clock recovery and smooth phase locking technology;

● An expansion interface (AUX1/2) can expand 1-2 channels of asynchronous data, such as RS232/RS485/RS422/TTL signals, etc.; or 1-4 channels of switching values, etc.;

● 4-way Ethernet interface 10/100M, full/half duplex fully adaptive, can support 4-way Ethernet isolation function;

● Each Ethernet port supports Auto-MDIX (cross/direct line adaptive);

● Equipped with anti-Ethernet loopback function (when a loopback occurs in the optical line, the Ethernet data will not be looped back, effectively preventing the Ethernet network from being paralyzed due to Ethernet loopback);

● 16-channel voice access, supporting caller ID function/reverse polarity billing/fax function; the phone supports mutual number allocation function for both sites;

● The voice port supports FXO/FXS/24-line EM/24-line audio/magnet telephone interface. The FXO port is connected to the program-controlled switch, and the FXS port is connected to the user’s telephone;

● The device has a power-down detection function, which can detect when the optical signal is lost, indicating that the peer device has lost power or the optical fiber is unavailable;

● 1 Console management interface; 1 SNMP management interface;

● Multiple power supply modes are available: AC220V, DC-48V/DC24V, etc.; supports dual power supply modes such as AC+DC; AC+AC; DC+DC;
