     Set the LOWER LIMIT of the length of the tone period during rings. It is
    not necessary to set this function unless ANSWER_DETECT returns a voice
    detect during a ring. This parameter is set in units of 32 msec cross
    count samples (32 msec - 1/32 seconds so 32 samples = 1 second). The
    default of this parameter is 25.  (25 samples = .8 seconds). The standard
    ring tone is 2 seconds on and 4 seconds off. The default is also set to
    detect a PBX ring of 1 second on and 3 seconds off. Adjust this parameter
    ONLY to adjust for phone equipment that does not support the standard. |
