Detailed Product Description

ISO9001:2000        OEM service offered

Product Description:

    EOP 4E1 to Ethernet converter realizes Ethernet transparent transmission over 1~4E1 with maximum transmit rate of 7.92Mb/s. EOP adopts with international standard protocol (G.7041G.7042G.7043G.8040) at all layers and able to intercommunicate with other suppliers products followed the same standard. The device not only provides perfect alarm/status indication for E1 and Ethernet interface, but with senior management function such as Ethernet data traffic statistics etc. The device is with high integration, low power consumption, stable performance and easy to use.

Technology  Characteristic:

   The Ethernet data will not be damnified if enlarge or reduce the transmission bandwidth.
   The E1 spur track on both ends can be connected not according to the serial number. When a single slip direction E1 fails, the other direction can still work.
   E1 automatic test loop back and cut off function. The E1 channel will be cut off once find E1 signal loop back. Auto-restore the use of E1 after release. Avoid the network storm without interrupting operations.
   Perfect alarm indication. Display local or terminal optional.
   Support local E1 channel side loop back function, facilitate to test E1 channels.

Transmission interface:
   Realize Ethernet data transmission over 1~4E1
   Support auto delete the fault E1 channels (BER more than 1E-6 or a serious warning LOS/AIS/LOF or the signal loop back); Auto-restore the use of E1 after eliminate the failure.
   For 4 E1 channels, the maximum tolerable time delay difference between any two can be up to 220ms. It will have an alarm for exceed the limit when the time delay difference over 220ms, meanwhile, business interrupt jitter tolerance, jitter transfer characteristics in the line with ITU-T G.823.

Ethernet interface: 
   Provide 4 maximum shared Ethernet interface, support VLAN division based on interface, in the line with IEEE 802.1Q standard
   Provide 1024 pieces MAC address table, the local data stream will not send to the terminal. 
   Support frame length: minimum: 64 bytes, maximum: 1916 bytes.
   Provide flux statistics for each Ethernet interface, such as the fault package number and total package number etc.
   Provide PAUSE flux control function, can be equipped with network management.

Management interface:
   Support trunk super terminal management or network management based on SNMP. (optional)In line with ITU-T standard:
   GFP-F encapsulation suggestion G.7041
   VCAT and LCAS suggestion G.7042
   Ethernet to nxE1 map suggestion G.7043
   Ethernet to E1 map suggestion G.8040
