Detailed Description

Features High-powered all-purpose unframed E1(2048kbps) and framed E1(N*64kps, N=1-31) to V.35 converter 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 2 kinds of machine model : standalone and rack-mountable. Overview V-GVE is an Asic-based converter using one E1/G.703 to convert to V.35. It can convert successive N*64K (N=1--32) data stream into PCM signal of E1. The data rate is up to 2048Kbps. Placed in E1 frame, data of user just need necessary timeslot. Setting timeslot is continuous and according with rate of data port. The data ports have V.35 and V.24/RS232C which are optional. The ports support external clock and become linking end line. V-GVE satisfies the requirements of G.703, G.704&G.706 of ITU. V-GVE has local and remote loopbacks. Therefore user can use circuity-test and malfunction diagnose conveniently.
