If the stream being received by the codec is dual mono (such as G.722), the decoded
audio is split between the two Livewire sources. The first source has the A mono feed
replicated on both left and right channels. The second source has the B mono feed on
both channels. Thus ‐ when you are using dual mono, you will use both codec outputs
as independent Livewire sources.
•
Remember, Livewire
described above, the mono data is simply replicated on both left and right channels.

Dual/Mono TRANSMIT works only in Layer 3 Dual/Mono mode. In Layer 3 Dual/Mono
transmit; the left channel of the first destination is used to create the "Channel A" mono
feed to be sent over ISDN. The second destination is used for the "Channel B" mono
transmit feed. The right channel of each of those streams is ignored.
A Word about Livewire Codec Backfeeds
Backfeeds to a codec in the Livewire
channel of the backfeed is a L/R mono sum of the configured program source (usually PGM1).
The left channel is the same L/R sum PLUS talkback. The left channel program can be dimmed
or muted when talkback is present.
Livewire Configuration Settings
It is important to get the basics configured properly before you attempt to configure Livewire
audio. Before we can get to the web pages for configuration of the Xstream, you will need to
give the Xstream an IP address from the front panel controls. This process is well covered in
Section 11.6 of the User's Manual.
Once you have assigned a unique IP address to the Xstream, it can be connected to your
network. To access the web pages, simply launch your favorite web browser and "aim" it at the
Xstream by entering the Xstream's IP address in the browser's URL box.
Let's now look at the Xstream's Livewire configuration web pages in detail. Let's start with the
important items on the Administration and drill down to the other items in the sequence that
you might use to setup your Xstream.
