----
<1> Overpower of maximum 2 dB for both SACCH and FACCH.
<2> Enable TOP only if RxQual is worse than 4 (BER >= 1.6%).
<3> Permit TOP for any kinds of dedicated channels.
<3> Permit TOP only for speech channels using AMR codec.
It's also possible to enable TOP only for FACCH or SACCH selectively, or
or keep it enabled permanently regardless of the reported RxQual:
For advanced use cases, OsmoBSC can be configured to:
* enable TOP only for FACCH or SACCH selectively, and/or
* keep TOP enabled permanently regardless of the reported RxQual, and/or
* permit TOP for any kind of dedicated channels.
