exceed more than 80% of your maximum bandwidth. If your link is shared, be even more
conservative.
You should also consider the remote end too. What is their maximum upload speed? Is the
connection shared at either end? Your bit rates, FEC settings and buffer rates must be pre-
configured at both ends before you connect, so it's always better to set your connection speed and
balance your FEC according to the available uplink bandwidth at each end for best performance.
As an example, if you want 15 kHz mono (using the Tieline Music Algorithm) you will need at least
a 24kbps connection for audio. Adding 100% FEC will add another 24kbps making your bit rate
48kbps plus some overhead of around 10kbps is required. If you're on a 64kbps uplink, you should
consider reducing your FEC to minimize the likelihood of exceeding your bandwidth capacity.
Here is another example, if you want 15 kHz stereo, you need at least 56kbps for the audio. 100%
FEC requires at least 112kbps and 50% FEC requires at least 84kbps. If your uplink speed is
256kbps and you're on a shared connection, then choosing a lower FEC setting of 20%-33% may
deliver better results.
Conserving Bandwidth with FEC
There is a trade-off between the quality and the reliability of an IP connection – particularly when
FEC is activated on your codecs. However, it is possible in certain situations to set different FEC on
each codec to match connection bandwidth requirements at either end of the link, conserve
bandwidth and create more stable IP connections.
For example, if your broadcast is a one-way broadcast from a remote site, i.e. you are not using the
return path from the studio, or only using it for communications purposes, it is possible to reduce or
turn off FEC at the studio codec. This effectively reduces the bandwidth required over the return link
(communications channel) and increases the overall bandwidth available for the incoming broadcast
signal from the remote site.

Configuring Auto Reconnect

Auto Reconnect is disabled by default. When enabled, the dialing codec attempts to reconnect
when data is not detected over a connection.
Important Note: When Auto Reconnect is enabled, the dialing codec will continue to
attempt a connection with the remote codec until the DISCONNECT
pressed, Disconnect is tapped in the Connections
disconnected in the HTML5 Toolbox Web-GUI.
