E1 to 2*V.35/V.24/X.21 Converter(GVE1-2)

Overview

GVE 1-2 is two V.35 ports (N*64Kbps, N=1-31) fractional E1 multiplex based on ASIC circuitry technology. Fractional E1 is framed E1. To make full use of the bandwidth of E1 channels, one can configure 2 V.35 ports separately in rate of N*64Kbps (N=1-31) to carry out time division multiplex. But the sum of rates of 2 V.35 ports must be less than that of E1 (1984Kbps). The start and stop time slots are configured by hardware switches, without any software input. Therefore saves not only equipment investment for users, but also lines investment of network operators.

Data is transmitted in transparency and lines impedance is optional between 120 ohm (RJ45) and 75 ohm (BNC). It is convenient to test local analog loop back and remote digital loop back to carry out port to port integrity test. When they are used in couple, V.35 ports will be cross-linked without one-to-one correspondence

Features

1. High-powered all-purpose 2 ports V.35 (N*64Kbps, N=1-31) E1 multiplex

2. Work mode: full duplex/half duplex

3. To fully utilizing of bandwidth of E1 channel, you can set up N*64Kbps rates of 2*V.35 ports apart. Every port time slot is set up with switches.

4. Rates: rates of 2* V.35 ports can be set up into synchronizing N*64Kbps(N=1-31). But sum of rates of 2 *V.35 ports must be less than that of E1.

5. Fully lucid signal converted and data transmitted clock mode to sustain G.703 network clock .

6. Convenient diagnosis function, test of analog loopback of local terminal and digital circular of remote terminal There are many director LED on the front panel to display work state and alarm signals of the equipment.

7. Lines are compatible with CCITT G.703, G.704, G.706, G.823. Lines code HDB3, under graded E1 mode, sustain CRC4ON / OFF, CAS / CCS optional There are corresponding director on the panel.

8. G.703 lines interface: impedance 120OHM(RJ45) and 75OHM(BNC) optional

9. When they are used in couple, V.35 ports will be linked across without corresponding one-to-one
