No, it applies to Xtra as well. I reluctantly moved from another ISP on
Jetstream Plus last year to Xtra, (as none of the UBS offerings suited my
needs) and my DSL line rate was previously 7616Kbit down, 384Kbit up, for
a plan that was 2Mbit down and 192Kbit up.

After the changeover to Xtra the DSL line rate has dropped to 2560Kbit
down and 160Kbit up, and I was forced to drop from 192Kbit upstream to
128kbit, even though technically I could have kept the old rate.

Ironically, if I had already been an Xtra customer back when the 192Kbit
plans were still officially available, I would have been able to keep the
192Kbit upstream as a grandfathered plan :-(

The only reason your DSL line rate is not set to 2560Kbit right now is
because your DSL line configuration is still a legacy profile - if you
change plans that involve any change in speed you will get "noticed" and
your line rate will be corrected...(or updated, Telecom would probably
call it)

It's important to note that the actual data throttling is NOT done by the
DSL line rate - but they do limit the DSL line rate to the data rate + the
necessary overhead to avoid the DSL rate being unnecessarily high compared
to the plan you're on.

Simon
