10. Set the DFXS Ringer Output Voltage.
This option sets the DFXS open circuit Ringing Output Voltage which is sourced via an internal
ringing resistance of 178 Ω per port.
The DC offset on the AC ringing signal enables ring trip to occur with a DC loop either during
ringing cycles. The normal DC line feed voltage enables ring trip to occur with a DC loop in the
silent period between the ringing cycles.
Selection Description
60 Vrms + 0 VDC Outputs 60 VRMS ringing with no DC offset
Maximum ringing voltage for high ringing load
applications but no DC ring trip
55 Vrms + 10 VDC Outputs 55 VRMS ringing with a 10 VDC offset
Medium ringing load applications
50 Vrms + 18 VDC Outputs 50 VRMS ringing with a 18 VDC offset
Above average ringing load applications
45 Vrms + 22 VDC Outputs 45 VRMS ringing with a 22 VDC offset
Typical application
Default
40 Vrms + 24 VDC Outputs 40 VRMS ringing with a 24 VDC offset
Lowest terminal power consumption
11. Select the DFXS Billing Tone Frequency.
This option sets the frequency of billing tone generation. If you are not sure what the expected
frequency of the billing tone should be, check with the exchange equipment supplier.
Selection Description
12 kHz Use if the CPE requires a 12 kHz billing tone signal
16 kHz Use if the CPE requires a 16 kHz billing tone signal Default
