Description

E1 to Ethernet Converter

Introduce

Features

High-powered Ethernet bridge converter to expand Ethernet transmitting distance and using range.

Ethernet UTP interface has function of VLAN802.1Q. There have two transmitting mode to choose: data and image.

10/100 Base-T(UTP) LAN interface accords with IEE802.3/Ethernet work mode: full duplex/ half duplex physical interface: shielded RJ-45 across and direct connection optional

G.703 can be framed N*64Kbps(N=1-31) and unframed 2048Kbps which are named fractional and unfractional apartly. Under the framed mode, it sustains alternative CRC4 ON/OFF, CAS/CCS (30 & 31 time slot). Transmitting clock can be recovered from receiving signal in

G.703 lines and also can work in internal clock mode.

GVE-T satisfies requirements of G.703, G.704, G.706 of ITU.

GVE-T has local and remote loopback. Consumer can test lines and diagnose faults conveniently to perform integrality test point-to-point.

Many director LEDs on the front panel display work state and alarm signal of equipment.

G.703 line interface: impedance 120ohm(RJ45)/75ohm(BNC) optional

Having two kinds of machine model: standalone and rack mountable power supply: -48VDC or 220VAC optional

Overview

GVE-T is a converter that uses one E1 line to transmit Ethernet data from G.703 to Ethernet Bridge for the purpose of expanding transmission distance and applicable range of Ethernet. It is developed with ASIC circuitry design technology. It is collocated with E1/G.703 as line interface.

GVE-T has local and remote loop backs. Therefore user can use circuitry-test and malfunction diagnosis conveniently to perform point-to-point integrity test.
