Not a published story, but a true one: in earlier days I needed quite 
a few ultra-fast modems (V22, i.e., 2400 baud) to be used for an 
unattended application (relatively unusual then). The reputable ones 
retailed at about 500GBP (we paid somewhat less).

ALL the expensive, reputable BABT modems we tried had design faults.
One refused to retry for hours after 4 failures due to an 
overenthusiastic interpretation of the blacklisting rules. Another 
had a software "black hole": under some circumstances it would lock 
up, and had to be power-cycled: very practical at a remote site at 
04:00 (the manufacturer refused to believe this could happen until we 
were able to show them). Yet another would only communicate at full 
speed with another of the same make and type. A fourth modem tended 
to interpret the ringing tone as busy about 50% of the time, and 
would hang up and redial. These were design faults that affected all 
units of a particular type, not faulty units.

ALL the unapproved modems tested worked perfectly. Unfortunately we 
had to use approved ones.

(Incidentally, BT were very strict about ensuring that only approved 
modems were used, to ensure the safety of personnel and integrity of 
equipment. However, we knew for sure that one of the main buyers of 
unapproved modems from our suppliers were B**t**h T*l***m).

HTH,
