GVE-T-g.703 e1 to 10base-t Ethernet converter network communication equipment

GVE-T-g.703 e1 to 10base-t Ethernet converter network communication equipment

Features & Benefits

>>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 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 port-to-port.

>>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. G.703 can be either framed N*64Kbps (N=1-31) or unframed 2048Kbps, which are also known as fractional and unfractional respectively. Under the framed mode, it supports choices of CRC4 ON/OFF and CAS/CCS (30 & 31 time slot). Transmission clock can be recovered from receiving signals in G.703 lines and can also work in inner clock mode.

The Ethernet UTP interface of GVE-T has VLAN802.1Q function.

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

GVE-T has two transmission modes to choose from: data and image.

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

There is a rich set of indicator LEDs on the front panel to display work status and alarm signals.

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