A lead assembly includes a flexible lead body which extends from a proximal end to a distal end, the lead body includes one or more conductors therein. Available channels may differ from one node to the next node and a node cannot use the same channel for both receiving and transmitting information. The subscriber station can by reading and decoding the indicator flag determine that there is no necessity to read data from the present frame or a succeeding frame and can therefore use the time period of one or more frames to save network resources or to perform inter-frequency measurements on another frequency. The method may additionally or alternatively include implanting a second set of dopants into portions of the semiconductor substrate bordering the recess. And, an arcuate skirt associated with the leg positively interferes with an improper mounting of the pump assembly in place.
