4E1-1FE interface Converter JHA-CE4F1

    • Based on self -copyright IC
    • To achieve Ethernet data transparent transmission in 1-4E1 circuits
    • Can realize the local and the remote device reset
    • Ethernet Interface is 100BASE-FX, support VLAN protocol
    • Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
    • Single Channel lines rate is 1984Kbit/s, 4Channel Bandwidth is up to 7936Kbit/s
    • Support all set of Ethernet Work Mode
    • CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single-direction. When 2M branch circuit one direction error rate exceeds threshold, cutting off this direction the other direction is not affected; that
    • Allow 4Channel E1 transmission time delay difference 100ms. When the margin exceed the allowed range, the system can automatically stop on the E1 that time delay is too large to send data
    • E1 interface conform to ITU-T G.703, G.704 and G.823, not support the use of signal timeslot

Ethernet to E1 Converter

  • 4E1-1FE interface Converter JHA-CE4F1


    This interface converter is based on FPGA, using reverse direction multiplexing technology to bundle for multiple E1 circuits to transmit the Ethernet data of 4Channel 100BASE-TX. It can realize 1~4 E1 channel to convert between Ethernet optical interface. This device can transmit the transceiver signal point to point to Ethernet optical interface to make E1 channels interconnected with Ethernet optical interface. Unlike general remote network bridge, this device can support 1-4Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available. It allows E1 lines transmission time delay difference.
