Methods of sampling substances such as subsurface contaminants, a transfer line for use in a system for such sampling, a sampling system and methods of manufacture and use of the system are described. The method includes lowering the downhole tool assembly into a well bore on a tool string, rupturing the rupture disk, allowing the lug to move within the continuous j-slot, and setting the downhole tool assembly by lifting upward and pushing downward on the tool string. One is that it allows call details, typically lost over International networks, to be obtained regarding the terminated call. In other cases, the present solution provides techniques for accelerating a protocol by improving the efficiency of obtaining and servicing data from an originating server to server to clients.
