The present invention discloses a method and a system for power saving management. The bipolar transistor further comprises a sacrificial post which, in one exemplary embodiment, is situated between first and second link spacers. In response to selection of a response option by a user, one or more of the address fields in the reply form are changed while maintaining the reply message in the input area. Further, there is formed a guide rail which fits in the cutout in the recessed part. A black matrix, a color filter layer or the like may be interposed between substrate 2 and phase difference control layer 3, and an electrode and an alignment film may be provided on the phase difference control layer. The method results in an E1 super channel being variably allocated to support both IS-95A service for low speed calls and IS95B service for high speed calls.
