16FXO/FXS+4E1+4FE+4*RS232/422/485 Fiber Multiplexer

This product provides 16 channels telephone, 4 E1 interfaces, 4 10/100M Ethernet ports (Wire Speed 100M), and 4 expansion ports. The 4 Ethernet ports are switch interfaces, which can support VLAN. 4 expansion ports can be used as the transmission channel of RS232/RS485/RS422 asynchronous data, voice signal, 2/4 wire E&M audio signal, dry contact signal, and Ethernet signal (Bandwidth 2M). Its application is very flexible.

● E1 interface complies with the G.703 recommendation, utilizing fully digital clock recovery and smooth phase-locked loop techniques.

● Voice ports support FXO/FXS, EM2/4 audio, and Magnet Telephone Interfaces. The FXO port is connected to a PBX, while the FXS port is connected to the user’s telephone set.

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

● The telephone interface supports the mutual dialing functionality between two sites.

● 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, etc. 

● The Ethernet interface supports 10/100M, half/full duplex auto-adaptable, and supports VLAN.

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

● Ethernet interface can support AUTO-MDIX (crossed line and straightly connected line self-adaptable).

● 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.

● The transmission distance is up to 2-120Km without interruption.

● AC 220V, DC-48V, DC24V can be optional.
