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.
