Section 9.1 says:

Mapping of ISUP/ISDN reason codes to Diversion reason codes is
performed as follows:
ISUP/ISDN reason code Diversion reason code
0001                  "user-busy"
0010                  "no-answer"
1111                  "unconditional"
1010                  "deflection"
1001                  "unavailable"
0000                  all others

It should say:

Mapping between ISDN reason codes and Diversion reason codes is
performed as follows:
ISDN reason code      Diversion reason code
0001                  "user-busy"
0010                  "no-answer"
1111                  "unconditional"
1010                  "deflection"
1001                  "unavailable"
0000                  all others
all others            "unknown"

Notes:

The reason codes are not ISUP but ISDN (ISUP deleted).
Missing the "all others" line in the ISDN to Diversion header mapping.
