DMS-100 ringing overview 1-7

DMS-100 Family DMS-100 Ringing System BASE15 and up

The frequencies used in the frequency selective ringing scheme are as follows:

• harmonic ringing: 16-2/3 Hz, 25 Hz, 33-1/3 Hz, 50 Hz, 66-2/3 Hz

• synchromonic ringing (20 Hz base): 20 Hz, 30 Hz, 42 Hz, 54 Hz, 66 Hz

• synchromonic ringing (16 Hz base): 16-2/3 Hz, 30 Hz, 42 Hz, 54 Hz

• decimonic ringing: 20 Hz, 30 Hz, 40 Hz, 50 Hz, 60 Hz.

Frequency selective ringing is used by Rural Electriﬁcation Association

(REA) ofﬁces. The following ﬁgures illustrate the REA frequency selective

ringing timing for the following types of ringing:

• synchromonic

• harmonic

• decimonic

Synchromonic ringing

The following ﬁgure illustrates the relationship between the synchromonic

ringing signals and the DMS-100 ringing cycle.

Figure 1-4 Synchromonic ringing

Note: Available frequencies are 16-2/3 Hz, 20 Hz, 30 Hz, 42 Hz, 54 Hz and

66 Hz. Any four of the available six frequencies, in any order, can be

assigned to frequencies A through D: however, 16 Hz and 20 Hz can not be

used simultaneously.
