4.12.5 Control Point Monitor
The Consolette supports Control Point Monitor as defined by the FCC. The local Consolette speaker
will unmute for remote (e.g. Wireline) audio that is being passed from the remote device to the
Consolette to be transmitted. When the local microphone is keyed, the local speaker will be muted to
voice audio. In addition, audio from the local microphone that is to be transmitted by the Consolette
is routed, via the wireline interface, to the remote device. (This is not needed for FCC Control Point
Monitor and can be disabled in the Consolette CPS see
section 3.7.1 ).
When the Consolette is being used by both a local and a remote user (TRC or ACIM interface) at the
same time, situations arise in which one user has priority over the other.
The following cases describe the effect of dual interaction:
• If the remote user performs a push-to-talk (PTT) while the local user is already keyed, the
remote user’s audio will be transmitted only if the remote user’s channel encryption state and
encryption key (CKR) align with that selected by the local user. If the remote user requested a
PTT on a different channel than what was selected by the local user, the Consolette will dekey,
change channels and a “bad” alert tone will be heard by both users until both PTTs are
released. If the remote user requested a PTT with a different encryption state than what was
selected by the local user, the Consolette will dekey, change encryption state and a “bad” alert
tone will be heard by both users until both PTTs are released. If the remote user requested a
PTT with a different encryption key (CKR) than what was selected by the local user a “bad
bonk” tone will be heard for the duration of the remote PTT press.
• If the remote user attempts to change channels while the local user is keyed, the Consolette will
dekey, change channels and a “bad” alert tone will be heard until the local user releases the
PTT.
• If the remote user attempts to change the state of encryption while the local user is keyed, the
Consolette will dekey, change encryption state and a “bad bonk” tone will be heard until the
local user releases the PTT.
• If the remote user attempts to change the encryption key (CKR) while the local user is keyed,
the Consolette will generate a momentary "bad bonk" tone to indicate that the encryption key
was not changed.
• If the local user performs a PTT while the remote user is already keyed, the local user’s audio
will be transmitted on the channel that the remote user has selected with the encryption state
and encryption key (CKR) that the remote user has selected.
• If the local user attempts to either change channels or the state of encryption while the remote
user is keyed, the Consolette will dekey and a “bad” alert tone will be heard until the remote
user releases the PTT.
• The local user is prohibited from changing the encryption key (CKR) while the remote user is
keyed.
4.13 Headset Operation (L999_ required)
Connections for up to two headsets are provided at the rear panel of the Consolette. The two RJ45
connectors are designed specifically for the Headset Jack Box (FHN7470_) in conjunction with the
Headset Amplifier Module Base with PTT switch (CDN6281). One Headset Interface Box is required
for each RJ45 headset connector on the Consolette. Standard Plantronics Headsets with phono
style plugs can then be plugged into the jack box.
NOTE: The FHN7470 Headset Jack Box kit includes cable kit (FKN8694A) which is incompatible with
the Consolette. This cable must be modified or replaced with a customer supplied 1-to-1
cable between the Jack Box and Consolette Rear Panel Heaset connector.
