What GHTROUT is saying is RTFM, see the useful document explaining basic routing (BARS 101). but to give you an example from what you have posted say you dial 95xxxx
9 = AC1
in AC1 you have:
SPN 5
RLI 4
SDRR NONE
ITEI NONE
In RLI 4 you have:
1st choice Route 21 (Look in LD 21 LTM, RDB to find out what is in this route and what sort of route it is)
DMI 1 (Look in LD 86 (Type DGT) to find out what is done to the 5xxxx before it is sent down this route
FRL 7 (This normaly maps straight through to NCOS but is setable in LD 87 NCTL, your call needs to have FRL 7 or higher)
2nd choice Route 22
DMI 1
FRL 5
3rd choice Route 23
DMI 1
FRL 4
etc.....
