Dears,
I'm a new Wireshark user and i have some questions about the tool:

    * Is it possible to make wireshark capture SS7 trace on the A
      interface (E1)? i am not talking about A signalling over IP but
      normal TDM mode, maybe something like a converter from Eth-RJ45
      (PC) to E1 (A-itf)!!don't know how it can be done?

See:

http://wiki.wireshark.org/CaptureSetup/SS7

    * How can i create a new custom column
      (Preferences/Columns/New/Custom)? i mean the format of this column
      for example i want to add a column to show the PCM/TS in the
      Assignment Request message in all the trace (like Tektronix K15
      shortcut Shift+A)

I've never used custom columns, but I think you need to use the display filter for the field you're interested (like "ip.src" or "mtp3.opc").
