(1) Does any one have any knowledge of this product ? ASCOM Baseband Modem AN6400 ( Based on second hand information , this may be a unit made by Northern Telecom ) There is a NSF sponsored experiment going online in Fiji this week and this CSU/DSU equivalent is required to connect to a Cisco to provide Internet connectivity. The local telco is only able to provide this unit and I want to know if it will work with a Cisco box ( I am also awaiting response from the Fiji Telco people, but they have never done anything like this before ) (2) The unit comes with a X.121 connector. ( as opposed to a V.35 ) Some other jargon thrown at me was ISO 4903 compliant and X21 bis Do we know this by some other name in the US ?
