Ken,  Some DSL service use frequencies in a higher passband then the 
standard DSL modem uses.  See W8JI's site for a detailed explanation on 
this.  My Westek TC-Z100B1 did virtual miracles for me after trying many 
other solutions.  My system is not a bundled ADSL-2 so the passband and 
cut off frequencies are most likely different.
