>> high-powered all-purpose unframed E1(2048kbps) and framed E1(N*64kps, N=1-31) to V.35 converters >> to fully use bandwidth fractional E1 and sustain cascade and time division multiplex(TDM), time slot is set up by switches. >> data rata: synchronism N*64Kbps(N=1-31)-2048Kbps >> fully lucid signal conversed clock mode to sustain DTE and G.703 network clock >> convenient diagnosis function, test of analog loopback of local terminal and digital circular of remote terminal There are many director lights on the front panel to display work state and alarm signals of the equipment. >> lines are according with CCITT G.703, G.704, G.706, G.823. Lines code HDB3, under graded E1 mode, sustain CRC4ON / OFF, CAS / CCS optional >> G.703 lines interface: impedance 120Ohm(RJ45) and 75Ohm(BNC) optional >> two kinds of machine model : standalone and rack-mountable.
