Wonder how many people will remember the Simi Valley based Micom
Communications Corporation that was very active in the early days of
Voice over Data (pre VOIP)? Their Marathon product was light years ahead
of the market (this whilst many of their competitors were still messing
around with analogue Mux’s).

With their Integrated Voice and Data solution they were able to come up
with an amazing technology that was so good, that 7 years after I
installed a Marathon Network, could not impliment a comparable Cisco
solution because their voice quality was so poor and unreliable!

Sadly Micom was bought out by Nortel who then proceeded to implode in a
spectacular fashion! A Great Product ... well ahead of it’s time, but now
simply a forgotten part of Data Communications history!

Which protocols did they used?
Were these standardized ones or proprietary?

In article <udhil7$1cao$2...@dont-email.me>, mo...@posteo.de says...
The Router card of the Micom Marathon could to my knowledge only route
IP & IPX traffic. The voice circuit cardwas totally proprietary and could
only be accessed by another Marathon unit with another voice card.

The proprietary voice protocol though was probably very much the reason
for the success of the product and why Micom became the market leader
at the time in the 1990's.
It was the reason Nortel bought the Micom company and quickly proceeded
to incorporate the entire marathon product into their Nortel Passport
range.

I was told that the Micom voice protocol was developed by a Mathematician
member of staff rather than a traditional Electronic Engineer.
His algorithms proved to be a huge success, and the main reason
competitors battled to compete with them. It took Cisco a decade to
get their voice solution even close to that of Micom, this based on my
own testing at the time.
