64Voice+4E1+4GE Fiber Multiplexer

The device provides 64-channel voice, 4*E1 interfaces, 4*1000M Ethernet interface, and 1 console or SNMP interface. The application is very flexible and it supports SNMP or Console for option, 1+1 fiber backup is optional.

● Voice FXO/FXS supports Caller ID display, reverse polarity billing, and fax function;

● The telephone interface supports mutual dialing between both endpoints;

● The voice port supports FXO/FXS/2-wire audio/magnetic telephone interfaces. The FXO port is connected to the PBX, and the FXS port is connected to the user’s telephone;

● The E1 interface complies with the G.703 recommendation and adopts full digital clock recovery and smooth phase-locked loop technology；

● The device has 4 Ethernet ports that function as switch ports and can support VLAN segmentation. Each Ethernet interface can be configured to provide logical isolation for a separate channel, giving a total of 4 channels.

● Ethernet interface rate of 1000M, full/half duplex adaptive;

● It provides a Console management interface;

● Unrepeated transmission distance of up to 2-120 km;

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

● DC-48V/DC24V power supply with automatic polarity detection function, when installed without distinction between positive and negative;

● The telephone interface comes with lightning protection that can withstand short-circuit current waves of 10/700μs and open-circuit peak output voltage of 6KV, in accordance with the GB/T17626.5 (IEC61000-4-5) standard.
