Teradata doesn't provide any builtin way to access data from two different Teradata servers within the same query, not in ODBC and not in BTEQ.
You have to write a table UDF or use a 3rd party application which allows that, but the data will be moved across the network and joined locally on the client, so better don't try that on a large table.
Why do you need to access data from two servers?
