TIA 660 : 1996

Defines the recommendations for the dialing plan and call processing treatment for use in Cellular Radio Telecommunications systems within the North American Numbering Plan (NANP). The scope of this Standard is limited to the description of dialing sequences and recommended treatment applicable to calls originated by cellular subscribers. The dialing sequences consist of the dialed digits which are carried from Mobile Station (MS) to the initial call processing point (e.g. the Mobile Switching Center). The adoption of a dialing plan is independent of a Cellular Radio telecommunications numbering plan. The development of a numbering plan is beyond the scope of this document.
