- Those 'tests' run by USR weren't exactly the most real world tests
- everdone on modems. They involved sending only 2560 characters. Way to
- small for a real test. This might have been due to the so called
- 'Spiralling Death bug' that USR had in its firmware at the time. Also
- the supervisor date of the firmware USR tested was Jan 2 1995. Don't
- believe that USR ever shipped that rev (Hmmm... preparing a special rev
- for at test house...) could be wrong on that but as I recall from
- following CDM USR initially shipped a Nov 94 rom then issued an April
- release to fix the spiralling death bug.
-
- The tests only checked two impairments noise and 3002 gain/delay curve
- ignoring the other impairments that affect modem transmission. Also the
- test sent data in both directions an area that USR does do well but in
- the real world most of us don't send data both ways simultaneously. So
- good bidirectional data throughput is hardly a good reason to spend the
- extra $50 that USR charges for their modem than most of the other modems
- in the test.
-
- Biggest complaint about them is that these test were non standard tests.
- There is a quite comprehensive test suite - TSB 37A and TSB 38, that has
- been developed to avoid people making up their own tests so they win and
- then claim that they are the best. As far as USR's claim that 'the test
- pushed the modems to their limits' its kind of hard to do this when you
- ignore the majority of impairments that are found on phone lines.
-
- The only thing these tests prove is that if you pay a consultant 25
- grand...
