Endpoint Security can be used with IP Endpoints that have been configured for SIP Standalone.
This will prevent them from being discovered/changed on the network using TalkMaster FOCUS Admin
Console unless the device is listed in the IP Endpoints tab with the correct password. Make sure to use
menu option File --> Export Settings and save the configurations to a secure location so that they can
be restored if anything happens to the PC that was used to configure the IP Endpoints.
Automatic Level Control
Automatic Level Control is a separately licensed feature of IP7 IP Endpoints that can be used to
automatically adjusts the volume level of IP Endpoints up or down one to two steps as the ambient noise
in an area changes.
An IP7 with a microphone is configured as an ALC Detector . The ALC Detector monitors the ambient
noise in an area and reports the normal level, the current level and the volume step change over the
network every 2.5 seconds. Please note that the ALC Detector should not be used for other audio
operations.
ALC Enabled IP Endpoints listening on the same Port number for Multicast Address 224.0.23.59 receive
information from the detector and adjust their volume level immediately. Once an ALC Enabled IP
Endpoint begins to play audio, it will ignore any other volume level changes till it is finished playing the
current audio message.
Since Digital Acoustics IP Endpoints have 7 volume steps, the ALC Enabled IP Endpoints normal volume
level should be set to level 3, 4 or 5 so that it can be raised or lowered by 2 steps.

o
Mall - (about 75dB)
o
Highway - (about 105dB)
o
Jetway - (about 135dB)

If the typical ambient noise level is different than any of the listed environments, the ambient
Noise Level can be automatically determined by measuring the current ambient noise level. See
