Hi Guys,

I have a question regarding the MFR1 events in the RFC2833bis document:

according to Q322\320\316 and refers to 464C and to Bellcore
documentation, the MFR1 characteristics are:


        US Mapping Names                Frequency
        1               700,900
        2               700,1100
        3               900,1100
        4               700,1300
        5               900,1300
        6               1100,1300
        7               700,1500
        8               900,1500
        9               1100,1500
        0               1300,1500
        KP1P            700,1700
        S1              900,1700
        K0/ or/ KP                1100,1700
        S2 /// KP2P               1300,1700
        S0/ or/ ST                1500,1700

This does not sync with the event table in the RFC2833bis document:

      a.      What is the frequency for the MF S3?
Good question. I wasn't able to find this in the limited documentation that I have. It is cited in any number of documents, such as RFC 2705 and various vendor documentation, but without any indication as to what it is and how it sounds like...


      b.      MF S2 and KP2P signals should have same frequency
      (1300,1700), meaning should have same event number (according to
      the RFC there are 16 frequency combinations instead of 15 ..).

I've removed that entry and marked it reserved.

      c.      According to the RFC KP1P frequency is 1100, 1700.
      according to our source (see above references) the right
      frequencies are   700,1700.

Thanks,

Oren Peleg
