Charge accumulated at an output node of an output transistor is discharged to the ground through the output transistor as a spike current. In one embodiment, an apparatus for generating a chemical precursor gas used in a vapor deposition processing system is provided which includes a canister having a sidewall, a top, and a bottom forming an interior volume and a solid precursor material at least partially contained within a lower region of the interior volume. This relieves wireless carriers of the obligation to install and maintain expensive dedicated SS7 or CAMA trunks from each MSC to each selective router in the areas served by that MSC. The child object appears to be enhanced by the methods and attributes defined by the set of interfaces and the methods implemented by the delegate object.
