4 Channel Fiber Telephone Multiplexer

Description:

This device provides 4Channel telephone 1-4Channel E1 interface, 4Channel 10M/100M Ethernet interface
(Line Speed 100M) and 4 expansion interface. 4Channel Ethernet interface is switch interface, can support
VLAN. 4 expansion interface can be used as the transmission channeof RS232/RS485/RS422 asynchronous data, voice signal, 2/4 line E&M audio signal, switch signal, Ethernet signal (Bandwidth 2M). It is very flexible.

Features
# Based on self -copyright IC
#E1 interface comply with G. 703, adopts digital clock recovery and smooth phase-lock technology
#Voice port supports FXO and FXS port, EM2/4 audio interface, FXO port docking with program-controlled switchboard, FXS port connected to the user's telephone;
#Voice FXO/FXS access, supports caller ID feature and reverse polarity billing functions
#Support various sites mutual number allocation function
#Provide 4 expansion interface, you can extend 1~4Channel asynchronous data, such as RS232/RS485/RS422/Manchester code; 1~4Channel voice, 1~8Channel switch, or two/four line audio #Ethernet interface supports10M/100M, half/full duplex auto- adaptable, support VLAN
#4Channel Ethernet interface is switch interface, support VLAN, can set to 4 channel logical isolation
# Ethernet interface can support AUTO-MDIX (crossed line and straightly connected line self-adaptable )
#The transmission distance is up to 2-120Km without interruption
#AC 220V, DC-48V, DC24V can be optional
