Modem init strings(Kill V.90)

   I work at an ISP and most of the communities we service have great phone lines, and get good connect speeds. However we have one community we service that has horrible phone lines, but we've noticed that if we disable V.90 on their modems it usually helps atleast a bit(we know they won't get above 26,400 but V.90 can really drag them into the ground) on LT WinModems, so we are looking for a good general resource as to modem init strings, especially how to can the 56k technologies, for a wide range of modems. Thank you, Jason

usually the best way to kill a v90 modem is s32=98, which will disable v90 & the X2 & Flex Protocols (under the new V90 standard)

I didn't notice any information on this page about disabling V.90 for the modems, it only appeared to be default settings for the modems, although definitly a great resource for that, sorry.
Are You Ready for GDPR?

With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

try this for winmodem ATS15=8S33=32.  

                                                       Courier            Sportster
             Disable V.90, enable X2:      S32=66           S58=32

             Disable X2, enable V.90:      S32=34           S58=1

             Disable both X2 and V.90:    S32=98           S58=33

             Enable both X2 and V.90:      S32=2            S58=1

this also works for sportsters S15=128

You answer works, from the testing I've done, but really the answer most of the people in the comments gave was what I was really looking for. Thanks
