E1-V35-4FX(FE1/V35+4FXO is a new-style multiplexing device. Provide conversion from 1channel framing E1 interface toV35interface, transmit 1 to 4 voice signals through E1 channel; FXS connect to the phone, FXO inset into PBX extension line.
Realize extend phone line through E1 channel and the advantage function of far-distance inner line call, audio signal definition is high, quality is excellent, support incoming call display, and inverted polarity charging.
E1-V35-4Fx realize both direction conversion between E1 interface and V. 35 interface date, can convert the E1 single channel of SDH? ? PDH fiber optical mux or microwave? ? Satellite to V. 35 date channel; And extend the V. 35 date channel of DDN, it is widely used in the date communication network, and connect with V. 35 date interface of router without G. 703 interface and fiber optical mux, realize V. 35 date and voice throwin at the same time.
Product character:
Having two row of LEDs, Realize monitor of remote equipment from local equipment;
Clock type? ? E1master clock, E1line clock;
Provide many loop function and pseudo random code test function, easy to test;
E1 can support rate N*64k(N=1-32); The range of rate is 64K~2048K;
Provide 1~4phone throwin, support incoming call display, and inverted polarity charging.;
