The Cisco ATA186-I1 and Cisco ATA188-I1 provide 600-ohm resistive impedance. The Cisco
ATA186-I2 and Cisco ATA188-I2 provide 270 ohm + 750 ohm // 150-nF complex impedance.
The impedance option is requested when you place your order and should match your specific
application. If you are not sure of the applicable configuration, check your country or regional
telephone impedance requirements.
