0 – 600 Ohm
1 – 900 Ohm
2 – 600 Ohm + 2.16uF
3 – 900 Ohm + 2.16uF
4 – CTR21 (270 Ohm + 750 Ohm||120nF)
5 – Australia/New Zeeland # 1 (220Ohm + 820Ohm||120nF)
6 – Slovakia/Slovenia/South Africa (220Ohm +
820Ohm||115nF)

! Ring Parameters –The Ring Parameters define parameters related
to definition of the ringer. These parameters are correlated because
of their influence on power consumption and power dissipation. The
validation function will define a priority in defining parameters as
follows:
-Line Resistance
-DC Component
- Waveform
- Amplitude
When starting with configuration of the Line Resistance, the other
three parameters are configured to their minimum values.
If the Ring DC Component is then changed, it affects just the
permitted range for the Ring Waveform and Amplitude parameters
(but does not change them again).
If a Ring Waveform that is not compatible with previous 2
parameters (Line Resistance and DC Component) is set, no change
takes place.
The Monitor interface includes a wizard, to guide the user in
programming these parameters in the best order. The Wizard
displays the status of all parameters programmed up to a specific
moment.
The Ring Parameters are applicable only to SUs with Voice HW
Revision D.
" Ring Frequency - The ringer frequency.
The available options are: 17Hz, 20Hz, 25Hz, 50Hz.
Default: country specific.
" Ring Waveform – The waveform of the ring signal.
The available options are Sinusoidal and Trapezoidal.
Default: country specific.
