3.1.22 responding device: A UPCS device that does not monitor its own transmit channel, but rather
operates in partnership with an initiating device, which monitors both duplex channels of a duplex
transmission pair in order to qualify both its own and the responding device’s transmit channel for
compliance with the spectral etiquette. See also: initiating device. This capability is used in accordance
with 47CFR15.323(c)(10) to simplify the implementation of a UPCS system.

ancillary fixed communication services to individuals and businesses without requiring operational license
from the regulatory agency.
