1.1.3.3 Ring Tone Pattern Selection
Description
A different ring tone pattern can be assigned to each incoming call type, such as intercom calls (
Extension Ring Tone Pattern [115]), calls from each doorphone ( Doorphone Ring Tone Pattern [706]),
and calls from each outside (CO) line ( CO Line Ring Tone Pattern [423]).
Available ring tone patterns are as follows:
[Ring Tone Patterns]
Conditions
• The ring tone pattern for incoming calls (intercom calls and outside (CO) line calls) to a single line
telephone (SLT) can be fixed to "Single" or "Double" for each extension through system programming
(
SLT Fixed Bell Pattern [629]). The length of the ring tone pattern depends on the preprogrammed
length of the bell-on signal ( SLT Ring Bell-on Time [143]), combined with the ratio between the bell
signals of the SLT ( SLT Ring/Silence Ratio [142]). Depending on the type of SLT being used, the
SLT may not ring properly, if the ring tone pattern of the SLT is set differently from that used by the
telephone company.
