The source-level routing that was used to test the TokenTalk NB Card and
TokenTalk software was IBM's Token Ring Bridge Program running on a PC.
However, any product that provides source-level routing should work with
TokenTalk. There should be no compatibility problem with the Internet Router
and the Upgrade Utility.
LocalTalk Peek can be used with both AppleTalk Phase 1 and Phase 2 networks. We
are not aware of any TokenTalk Peek.
