16Voice+8E1+4GE+4RS232 Fiber Multiplexer

This device provides 16 telephone interfaces, 1-8 E1 interfaces, 4 10M/100M Fast Ethernet interfaces (at line speed of 100M), and 4 extended interfaces. The 4 Ethernet interfaces can be used as switching ports and support VLAN partitioning. The 4 extended interfaces can be used as transmission channels for RS232/RS485/RS422 asynchronous data, TTL signals, dry contact signals, and more.

● E1 interface complies with G.703, and adopts Full Digital Clock Recovery and Smooth Phase-Locked Loop technology;

● Voice port supports FXO/FXS, EM2/4 audio, Magnet Telephone Interface. The FXO port is connected to the PBX, while the FXS port is connected to the user’s telephone;

● Voice port supports caller ID display, reverse polarity charging, and fax function;

● Support mutual dialing function between two stations;

● It provides 4 extended interfaces, which can be used to expand 1-4 channels of asynchronous data transmission, such as RS232/RS485/RS422/TTL, or 1-8 channels of dry contact signals;

● The Ethernet interface has a bandwidth of 100Mbps and supports line speed 10M/100M, full/half duplex auto-negotiation, as well as VLAN partitioning.

● The 4 Ethernet interfaces can be used as switching ports and support VLAN partitioning. They can also be configured as 4 logical channels for network isolation;

● Each Ethernet ports support Auto-MDIX (cross/straight cable adaptation);

● The transmission distance for non-relay communication can reach 2-120 kilometers;

● Multiple power supply options: AC220V, DC-48V / DC24V, etc;

● The telephone interface is equipped with lightning protection that meets the GB/T17626.5 (IEC61000-4-5) standard for short-circuit current wave of 10/700μs, and can withstand a peak output voltage of 6KV under open circuit conditions.
