Hi,

I have two questions.  The first deals with Ethereal, and the second
deals with how to interpret the ITU format:

  1) I noticed that SSCOP is on the list of protocols supported
     by Ethereal.  What is required to see the decoded messages?
     Does this work over UDP?  I am seeing just one Data chuck
     being displayed within the UDP packet.

  2) I am not sure how to interpret the ITU Q.2110 spec.  It
     shows, for example, the Poll PDU as:

         |      1     |    2    |    3    |    4    |
        -+------------+---------+---------+---------+
        1|  Reserved  |          N(PS)              |
        -+------------+---------+---------+---------+
        2| Rsvd | PDU |          N(S)               |
         |      | Type|                             |
        -+------------+---------+---------+---------+
          8765   4321

     Let say that:

       Reserved=0x00
       N(PS)=0x987654
       Rsvd=0x00
       PDU Type=0x0a
       N(S)=0x123456

     Would this be displayed as:

        00 98 76 54 0a 12 34 56

     or perhaps as:

        00 54 76 98 0a 56 34 12
