Abstract
Wireless service option number assignments are divided into related groups. One group comprises voice service options: #1 (TIA/EIA-96-C “basic” 8k), #3 (IS-127 EVRC 8k), and #17 (IS-733 13k) which refer to different voice rates. Other groups may include data services; however, several subgroupings are possible, and may be used to keep the size of each group at a manageable level. The TIA/EIA-96-C is hereby incorporated by reference. Definitions for each related group of service options (i.e., bitmap) would be maintained in a standard such as TSB58. The TSB58 standard is hereby incorporated by reference.
