ATA Voice Field Reference PSTN Line page (SPA3102) B Voice tab > PSTN Line page (SPA3102) > International Control (Settings) section FXO Port Impedance Desired impedance of the FXO Port. Choose from {600, 900, 370+620, 270+750||150nF, 220+820||120nF, 370 + 620 || 310nf, 320 + 1050 || 230nf, 370 + 820 || 110 nf, 275 + 780 || 115nf, 120 + 820 || 110nf, 350 + 1000 || 210nf, 0 + 900 || 130nf} The default is 600. The impedance values for various countries follows: US-600 EU (UK, Germany, Netherlands, Sweden, Norway, Italy, Spain, Portugal, Poland, and Denmark)-270+750||150nF France-270+750||150nF Australia-220+820||120nF New Zealand-370+620||310nF Ring Frequency Min Specify the lower limit of the ring frequency used to detect the ring signal. The default is 10. SPA To PSTN Gain dB of digital gain (or attenuation if negative) to be applied to the signal sent from the SPA to the PSTN side. The range is -15 to 12. Ring Frequency Max PSTN To SPA Gain The default is 0. Specify the higher limit of the ring frequency used to detect the ring signal. The default is 100. dB of digital gain (or attenuation if negative) to be applied to the signal sent from the PSTN side to the SPA. The range is -15 to 12. Ring Validation Time Tip/Ring Voltage Adjust The default is 0. Specify the minimum signal duration required by the Gateway for recognition as a ring signal. The default is 256 ms. Choices are {3.1, 3.2, 3.35, 3.5}. The default is 3.5. Cisco Small Business ATA Administration Guide 218
