76. gt Important Note FEC can only be programmed for use with the Music and MusicPLUS algorithms How does FEC work If you program a FEC setting of 2096 and you are losing one packet in every five sent the lost packet will be replaced by FEC to maintain the quality of the connection If you are losing more packets than this say one in three it will be necessary to increase the FEC setting to 3396 to compensate Note There is an inverse relationship between FEC settings and the jitter buffer millisecond setting that you use for IP connections So why not use 100 FEC every time The answer is because you need twice the bit rate to achieve full redundancy and depending on the link conditions this could potentially cause more dropouts because of network congestion than it fixes Here is a simple rule to remember Your maximum uplink speed is all the bandwidth you have to play with As a rule of thumb try not to exceed more than 8096 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 ls 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
