Is there a link broken somewhere?

I've seen messages after mine responded to, so perhaps this one never made it 
out. Here it is again:

I own an Optima 28.8 V.FC/V.34 purchased two and a half years ago on the 
sysop program.
Some time ago, I capped my modem at 26.4 with S37=34 to solve a problem I was 
having with a couple of downlinks with older, flakey Zoom V.FC modems. After 
that, my problems seemed to be mainly limited to occasional 300 bps connects 
with the Zooms (and only the Zooms, three or four times a week). They've 
recently upgraded, and I took the cap off the Hayes.
I'm now having the same 300 bps problems with the same frequency with the 
Zooms. I'm also having a hell of a time with my uplink and a couple of 
downlinks, all of whom run USR Courier V.everythings. Bink reports numerous 
retransmits, and the vast majority of the time the line is dropped. When a 
connect manages to hold for the entire session, I get drastically reduced 
throughput (~2300 cps), even on 26.4 connects that used (before I took the 
choke off) to be fine (~3000 cps or so).
Help!
FYI, ATI7 returns an ERROR (!?). ATI0 returns 28800, ATI2 returns OK.
My init string is ATZ1, with NVRAM settings as follow:
B1 B16 B30 B41 B60 B70 B75 B80 E1 L2 M0 N1 P Q0 V1 W1 X4 Y0 &A0
&C1 &D2 &G0 &K3 &Q5 &R0 &S0 &T5 &U0 &X0 &Y1 S00:000 S02:043 S03:013 S04:010
S05:008 S06:002 S07:050 S08:002 S09:006 S10:014 S11:095 S12:050 S25:005 
S26:001 S36:007 S37:015 S38:020 S46:002 S48:007 S49:064 S50:192 S108:003
S109:4095 S110:002
I'm surprised to be having so many problems, especially given the value of 
S108. One of my downlinks with a Courier tells me that the nifty link stats 
his modem gives him describes lots of "blers". Perhaps more on this if he 
forwards me his stats as I've asked.
Any ideas?
