SUN-EC Ethernet Convertor

Model: SUN-EC

E1 to Ethernet

    Key Features

  • Realize transparent transfer Ethernet data in 1 to 4/8 E1 channels
  • 10M/100M Ethernet, full/half duplex self adapt, support VLAN
  • Ethernet support AUTO-MDIX( cross over and straight through self adapt)
  • Setting CRC alarm limitation to auto isolate lines with low transfer quality, single direction. When one direction error rate over limitation, disconnect only one direction, the other is not affected. Unbalance in two directions
  • Allow 4 E1 channels up to 10ms transfer delay. when the delay over the limitation, can stop transfer automatically
  • Support Dynamic Ethernet MAC address(4096), having local address filter function
  • E1 interface having internal clock resume circuit and HDB3 codec circuit
  • E1 circuit number auto-negotiation, E1 circuit auto assemble/disassemble
  • E1 interface compliant to ITU G.703, G.704 and G.823
  • Provide balanced 120-Ohm RJ45 or unbalanced 75-Ohm BNC E1 interface
  • Optional copper or fiber optic Ethernet interface
  • Support reset remote system from local system
  • Support SNMP function (Optional)

  •  Sun Telecom’s SUN-EC series of Ethernet convertors apply reverse multiplexing technology to transfer 10M/100M Ethernet data by using E1s. It realizes conversion between 1 to 4/8/16 E1 channels and Ethernet interface. It is capable of providing a real Ethernet throughput of 8Mbps respectively. And it also automatically adapted to lower data rates from 2Mbps, in case that less E1 circuits is employed.
