There's only one way to fix oversubscription and that's with the capacity upgrade to the UBR to increase its throughput.
Sorry two, kick some customers off the network who shouldn't have been signed up in the first place. But the extra income out ways the compensation, hassle and loosing face admitting it was your fault in the first place.
Sorry three, get rid of the modem clones off the network.
Sorry four, please feel free to continue the list as the footies just about to start,
comon England and well done the U21's last night

If you're been told that your area is oversubscribed, the only thing I can suggest is to find out what card on the UBR you're on (should look something like this: ubr02abcd 2/0) and ask on newsgroup support if there's any work planned on it for capacity. Remembering that any dates given are `subject to change' and boy do they change a lot or was it a carrot dangling in front of me to make me stay.
It took me 4 months to find out I was in an oversubscribed area and further 8 for the problem to be resolved (sort of, still dodgy sometimes peak times).
If you're out of contract and you find out the dates not to your satisfaction switch to an DSL ISP or if the date is OKish I definitely wouldn't pay any where near fully price for the service and if you're still in contract you're got to prove it's not fit for purpose and ask to leave.
Laters,
