streams will not flow through most Internet routers. Therefore, unicast addresses are
acceptable for use in the AudioMate 360 line of IP gateways, although multicast is preferred..
Bandwidth Consumption and Codecs
The G.711 codec (encoder/decoder algorithm) consumes approximately 84kilobits/second
per stream. More aggressive codecs consume less bandwidth, but their output audio is
typically of lower quality. Some codecs perform poorly in environments with high acoustic
noise near the microphone. Narrowband IP links might require a more aggressive codec,
while endpoints on your LAN will likely do well with the G.711 codec. Because the AudioMate
Media Server can perform transcoding between algorithms you have the opportunity to
optimize bandwidth usage versus audio quality.
Electrical Considerations
The AudioMate 360 gateways are powered by 12 Volts d.c. which can be provided by the
supplied plug-in power supply or by a 12 Volt battery with float charging system. In either
case, the power must be clean and free of a.c. noise components and interruptions. The
supplied power module should be plugged into an uninterruptible power supply (UPS) for
trouble-free service. If a 12 Volt battery/charger system is used, the charger must keep noise
to less than 12mVp-p.
Conguration
Individual AudioMate 360 units are configured via web browser pointed to the management
address of the unit. The units are shipped with DHCP enabled and will accept whatever
address is assigned by your DHCP server, within approximately 60 seconds after power-up.
Failing that, the units will default to an IP address of 192.168.0.254 after timing out. Use
the AudioMate 360 address finder utility to locate the addresses of your units in preparation
for configuration.
Each unit requires two groups of configuration data: one group that is common across the
AudioMate 360 family and a second group that is specific to the personality module of the
unit.
Log In
Type the address of the AudioMate 360 unit under test into the address bar of your web
browser. (At the time of this writing the freely available Mozilla Firefox web browser provides
smoother operation for these purposes.) If a name had been previously assigned to this
particular AudioMate 360 unit it will appear in the title bar of the web browser to assist in
identifying it. At the prompt, for user name type admin and for password type the word
password.
If your credentials were accepted you will see a two part screen with a menu panel on the
left pane and a page labeled AM Status on the right pane.
Global Conguration
In the menu pane on the left, locate the Configuration heading and click the link Global
under it. The screen labeled AM Configuration should appear in the right pane.
You may safely ignore the AMCP settings.
