Here is my take on it. (BTW, where do you see a Ascend mentioned in this
report?)
1. Not surprisingly to me, the XXCAL report clearly documents that the
Livingston PM3 out performed (in total combined thru-put) the USR TC
chassis, at every point from a single user all the way up to 17 concurrent
users. The USR TC chassis ** never once ** uploaded or downloaded files in
speeds greater than 7000 bytes per second. The PM3 ** consistently exceeded
** 7000 bytes per second, in every instance, from a single user all the way
up to 17 concurrent users. Thank you USR for substantiating what we are
ready knew. ;-)
2. USR would have the reader believe that the PM3 reached a saturation
point at 17 concurrent users and could not process any more dial-in
connections beyond 17. This is a blatant misrepresentation of the truth.
The real reason the PM3 did not go beyond 17 concurrent users is that the
PM3 experienced a compatibility problem with a Teleos Model 60 phone line
simulator. This compatibility problem resulted in the PM3 terminating calls
and ** does not ** represent any under achieving in performance.
3. This test was performed on a test bed, not using real-world using AT&T
or Nortel switches, but a simulator. And I know most of you all run your
networks on phone line simulators, just like the one in the report. ;-)
