- It took four years to decide on V.42, less than two to decide on
- V.42bis. It took almost four years for V.32, less than one for
- V.32bis. It varies widely, for a lot of reasons. Certainly
- politics is among them, but I think in the case of V.fast the
- problem is that there are a lot of quite viable ways to make a modem
- run faster than 14400. With so many techniques to choose from, it's
- tough to make a decision (particularly with the patent issues in the
- back of everybody's mind). It has taken a long time to agree on a
- model of the CURRENT telephone network with reasonable weighting of
- the likelihood of occurrence of various impairments, so that we have
- an "objective" way to compare the proposals. I believe the
- committee will now have the information it needs to settle on the
- best techniques within the next six months or so, but it will still
- take another six months or more to finalize the text -- then another
- six months for the balloting of the countries.

- They've all promised to upgrade the products to the standard. What
- can you do but take their word for it, assuming you just HAVE to
- have one now?
