A Negative Thermal Expansion system device for TCE compensation or CTE compensation in elastomer composites and conductive elastomer interconnects in microelectronic packaging. The unit also includes an evaporator through which a portion of the feed water conduit and the gas conduit pass. This problem is solved by the application in that the port of telephony link used by the switching apparatus for the call by which the PIN data is transmitted is transmitted in combination with the CLI over the CTI-link. A system suitable for use in carrying out the process is also disclosed.
