ACU-1000 Operations Manual
2-108 Interoperability Now
set in Section 2.17.4.7 as the ACU-1000 attempts to make the connection. If the extension is
busy, a busy tone will be heard. The factory default generates the standard US tones, which is
currently the only style offered
2.17.4.7 Ring Cadence
The cadence of the ring the LP module sends to the associated telephone set is selected by this
configuration item. Two styles are offered; the standard US style (factory default), and
European style. This ring cadence applies both to the tone heard in the LP-2’s earpiece when a
call is being made and to the ring that is produced when a call is placed to the local phone
(ringback).
2.17.4.8 Dial Tone Enable
The LP module can generate a dial tone whenever a caller picks up the handset of the
associated telephone set in order to place a call. If desired, this dial tone can be disabled.
2.17.4.9 Ringback Enable
When a call is placed to the extension occupied by the LP module, the module can signal that
this call has been made via its ringback signal. For example, if an ACU-1000 user attempts to
make a connection with his UHF radio to an extension occupied by an LP, he will hear this
ringback signal as he waits for the handset at the LP to be picked up. It’s possible to disable
this ringback signal; in this case the UHF radio user will not hear anything as he waits for his
call to go through. See Section 2.17.4.7 Ring Cadence, and Section 2.17.4.10, Ringing Time.
2.17.4.10 Outgoing Ring Timer
The length of time the LP module causes its associated phone set to ring when a call is received
is adjusted by this configuration item. The selection options are: no ring, a 30 second ring
(factory default), and a 1 minute ring; or alternatively a continuous ring. When set for either 30
seconds or one minute, the call will time-out if the call is not answered before the Ringing
Time elapses. When set to “no ring,” no outgoing calls are allowed. If set for continuous ring,
the incoming call does not time out and the phone will continue to ring until the call is
answered or terminated by the originator.
2.17.4.11 DTMF Command Enable
This command determines whether an ACU-1000 module considers any DTMF characters
present in its input audio to be commands meant for that module. When DTMF commands are
disabled, they’re blocked from passing through the module. Instead, the DTMF characters are
detected and muted, but are not considered as commands to the receiving module. The default
factory setting is DTMF Commands enabled. In this mode, the DTMF characters are still
detected and muted, but the receiving module assumes they are incoming commands and
responds accordingly. See Section 2.17.4.1 for proper DTMF Mute Timer adjustment, and
Section 3.5.1.9, which explains the Data and Command modes, which can be used to
temporarily control the use of DTMF input, without having to enter the programming mode.
