much common circuitry as is practicable so as to ensure that under
fault conditions the recording of a telephone conversation is unlikely
to occur without the recording tone generator transmitting warning
tones to line.
5.8.6 Distant party notification and recording tone
CE should comply with the following:
(a) Distant Party Notification
Recording tone should be transmitted to the distant party
during recording of a conversation. Recording tone may be
transmitted to the local telephone, operator’s headset and
the conversation recording device in use.
(b) Recording Tone
(i) The recording tone should be a tone of 1400 Hz ±1.5%
with a duration of 425 ms ±75 ms bursts.
(ii) The recording tone should be repeated at 15 s ±3 s
intervals.
(iii) The power level of each tone burst at the point of
connection to the PSTN line (Line Port) should be in the
range –10 dBm to –24 dBm when measured across a 600
Ω termination connected to the Line Port, and a 600 Ω
termination (representing the telephone) connected
across the Local Telephone Port, if any.
Note: It is recommended that the level of Recording Tone
applied to the Local Telephone Port is not greater than
–20 dBm.
Note: There is Commonwealth and State legislation relating to the
recording of, and listening to, communications over the
Telecommunications Network. Compliance with this Standard
should not be taken to mean that any subsequent use of the
equipment complies with relevant legislation.
