                              GQ1001B 10/100Base-TX Ethernet over E1 Protocal Converter

             GQ1001B Ethernet Over E1 Interface Converter which offers a channelized E1 and 10Base-T interface conversion. This equipment offers electrical level conversion between 10Base-T Ethernet interface and a G.703 / E1 (or fractional E1) interfaces.

       GQ1001B is an Ethernet extension device utilizing TDM telecom infrastructure( the telecom networks of E1s,or of PDH,SDH and E1/E3/SDH microwave etc. Carrying E1s). It converts the Ethernet data into E1 frame format for transmission over the existing TDM(E1)links and then re-converts the E1 back into Ethernet data the far-end terminal,to bridge two Ethernet LANs over the existing E1-based telecom network. The device can effectively utilize the redundant bandwidth of telecom operators' existing TDM network to transport Ethernet data with low investment.

    The equipment be always installed and used in pairs, with one terminal being installed at either end of the network.


lThe maximum transmission rate of Ethernet data over E1 links is 2.048Mbit/s

lE1 supports two working modes of transparent transmission: framed(CCS/PCM31) and unframed

lAllow transparent transmission of super-long frames in 2024bytes and supports Ethernet switchers with VLAN function

lEthernet interface supports 10/100Mbps half/full-duplex, automatic negotiation

lAvailable with MAC address list filtration, learning and updating functions

lAvailable with auto-resetting function. When network port stops receiving or sending data about 8seconds, the auto-resetting circuit will be able to start automatically, to reduce and maintain workload for the system

lSupports two working modes : internal clock and external clock

lSupports RLOOP(E1 port external loop-back)

lE1 channel support built-in BERT(Bit Error Rate Test) function

lSupport flux control based on the 802.3x

lProvide a management interface, can be flexibly config the device

lPlug and Play
