dences is described on page 6–32 of the AXXESS manual.)

Standard CO Ring This is a repeating 6-second cadence that rings
once for 2 seconds followed by 4 seconds of
silence.
Extended CO Ring This is a repeating 6-second cadence that rings
once for 2 seconds followed by 4 seconds of

seconds.
Extended IC Ring This is a repeating 3-second cadence that rings
once for 1 second followed by 2 seconds of
silence.
Standard CO Ring This is a repeating 6-second cadence that rings

lowed by 2048 milliseconds of silence.
Extended IC Ring This is a repeating 2-second cadence that rings
