This section provides data values required for SS7 ICBs, including the following:
• SS7 Parameter IDs
• MTP Statistics Parameter IDs from Q.752
See "SS7 ISUP Message Format Configure 0x6B" for a list of ISUP Message IDs.
The following is a partial list of SS7 parameters. For a complete list and coding, consult the appropriate ANSI or ITU specification.

MTP3 Timestamp This value is a 1msec resolution, modulus 2^32 timestamp derived from the internal processing logic of MTP3. The datum of this timestamp is established internally by each MTP3 at the time the signalling stack is configured and cannot be set. As presented, the timestamp should only be used for relative timing of MTP3 Q.752 events and reports within a signaling stack. The timestamp for interval reports identify the time associated with the end of the reporting interval and not the time of the actual report. Consequently, host attempts to correlate the timestamp to a time datum must consider only the 1st interval report of a sequence for this correlation. |
|
0x0001 |
Interval sequence number This value is a modulus 2^32 sequence number which identifies the reporting interval. The initial value for the first reporting interval following start or restart of interval reporting is 1. |
