requirement of 47CFR15.323(c)(4) that the control and signaling channel be tested against the access
criteria at least every 30 s.
An EUT may transmit a control and signaling channel only, or a communications channel only (see the
definitions in 3.1), both types of channel at once, or each at different times. An EUT’s physical time and
spectrum window may change from transmitting a control and signaling channel to transmitting a
communications channel, or vice versa, during the operation of a system incorporating the EUT.
Executing the test procedures may require that the manufacturer provide information to identify those
transmissions that correspond to a control and signaling channel and those transmissions that correspond to
a communications channel, as the spectrum etiquette requirements for acknowledgements during continued
transmission differ. If the EUT may use the same physical time and spectrum window for a control and
signaling channel and for a communications channel, the manufacturer shall provide means for determining
which type of channel is present.

8.1.1
Timing for EUTs using control and signaling channel-type transmissions
The tests of 8.1.1, 8.1.2, and 8.1.3 are applicable for an EUT capable of transmitting control and signaling
information (beacons) on its own when no companion device(s) is present, and are to be made under
unacknowledged transmissions conditions.
Note that an EUT that transmits a control and signaling channel must pass the test of 8.1.1 and must pass
either the tests of 8.1.2 or the tests of 8.1.3.

Access criteria test interval
This test is for an EUT transmitting control and signaling channels, and validates that the EUT tests the
access conditions at least as often as once every 30 s when no acknowledgement is provided for control and
signaling channel transmissions.
The test procedure is as follows:
access conditions at least as often as once every 30 s when no acknowledgement is provided for control and
signaling channel transmissions.
The test procedure is as follows:
a) Use frequency administration commands or out-of-operating-region interference (using the
procedures in 7.2.3) to restrict operation of the EUT to a single carrier designated f
1
. If the EUT
communications protocol uses TDMA to provide multiple channels per carrier, it may be
necessary for test-result observability to additionally use frequency administration commands or
out-of-operating-region interference to further restrict EUT transmissions to a single timeslot of
the usable timeslots available in the TDMA frame structure. If necessary, the manufacturer shall
supply means by which to synchronize the interference with the timeslot structure of the EUT.
The interference shall be timed so as to occur centered within the timeslot.

b) Activate the EUT. The EUT, if it transmits, must do so on f
1
, and if the EUT is a TDMA device,
it must additionally do so on the unblocked timeslot, if timeslot blocking is used. The EUT must
terminate or pause in its repetitive transmission of the control and signaling channel on the open
channel to repeat the access criteria not less frequently than every 30 s. If the channel in use for
transmissions meets the access criteria, the transmission may start again on the same channel
after the access criteria test. Measure the interval between access criteria tests. Repeat this
measurement five times. If the EUT fails to repeat the access criteria test at intervals of 30 s or
less each time, the EUT fails the test.
