For the purposes of this document, when illustrating the prompt/response sequences, the bold type is what the user enters on the keyboard. All other type represents the DAC output. Likewise, “xxxxxxx,” “yyyyyyy,” or “zzzzzzz” represents numbers entered by the user, or dialed by the DAC, and in no way indicates the absolute character limit. The number of characters is dependent on the feature activated (Auto Dial, Speed Call, for example). Also, for simplicity purposes, all Result messages are shown in Verbose code. See Table 154 on page 475 for a complete list of the Verbose and Numeric codes. See Features and Services (553-3001-306) for a complete description of the features operating.

S registers

These commands allow the user to access various dialing parameters. The user can determine the present parameter setting, and alter the parameter. These parameters are grouped into a set referred to as the S registers.
