1403-02: Single Ring for Single Line Set [System: Class of Service: SLTs: SLTs(1403): Single Ring]

Use this option to determine the type of ringing at analog single line extensions. If enabled, analog single line extensions always receive single ringing for outside calls. (Certain analog single line devices connected to the system may require this type of ringing.) If disabled, line ringing at analog single line extensions follows the ringing pattern of the line. For example, if a line is ringing the system with two ring bursts, the single line extensions will follow the same ringing pattern.
