Most remote codecs dial from the remote broadcast site back to the studio. However, if the remote codec is going to answer incoming calls, it is possible to lock a loaded custom program in a codec to ensure the currently loaded program type, e.g. mono peer-to-peer plus IFB, cannot be unloaded by a codec dialing in with a different program type like peer-to-peer mono.
For example, if the codec should always connect using mono peer-to-peer plus IFB, simply load and lock this program in the codec. Another reason for locking a program in the answering codec is to always use a particular jitter buffer or FEC setting.
Generally programs will be up or down-mixed by the answering codec to match the loaded program type. In some situations incompatible program types will be rejected. A compatible program type can still connect and specify different connection parameters such as the algorithm and bit rate via session data.
1.Press the HOME 
button to return to the Home screen, then tap Settings 
.
2.Tap to expand the Answering menu and then tap Lock Program 
.
3.Tap the On/Off button to toggle between enabling and disabling Lock Loaded User Program (default setting Off).

Important Note: It is only possible to lock custom programs in a codec. If Lock Loaded User Program is enabled and you load a new custom program in the codec, the feature remains enabled and locks the most recently loaded custom program. |
