Description:
Wireshark dissector for ONT Management and Control Interface (OMCI) protocol (ITU-T G984.4, ITU-T G988)
This protocol is used on Gigabit Passive Optical Network (GPON) between Optical Line Termition (OLT, the network side) and Optical Network Termination (ONT, the end user side) units.
This is management protocol used to configure services (like Ethernet, QoS, Video overlay, Tx/Rx control) on the ONT.
The dissector applies on UDP or Ethernet packet that contains a copy of OMCI data going between ONT and OLT as explained in appendix III of ITU-T G988

The dissector binary to hexadecimal conversion, module available at http://www.dialectronics.com/Lua/code/BinDecHex.shtml
Note from the author:
*) Not all ME classes described in the OMCI standards are supported in this dissector (any support to complete the list is very welcome)
*) This implementation is the first LUA SW written by the author. It (certainly) could be more efficient (any comment is welcome)
