debug vtsp vofr subframe command. Use the no form of the command to turn off the debug function.
[no] debug vtsp vofr subframe payload [from-dsp] [to-dsp]
Syntax Description
Usage Guidelines
Each debug output displays the first 10 bytes of the FRF.11 subframe, including header bytes. The
from-dsp and to-dsp options can be used to limit the debugs to a single direction. If not specified,
debugs are displayed for subframes when they are received from the DSP and before they are sent to
the DSP.
Use extreme caution in selecting payload options 0 and 6. These options may cause network instability.
payload Number used to selectively display subframes of a specific payload. Payload types are:
0: Primary Payload - WARNING! This option might cause network instability
1: Annex-A
2: Annex-B
3: Annex-D
4: All other payloads
5: All payloads - WARNING! This option may cause network instability
from-dsp Displays only the subframes received from the DSP.
to-dsp Displays only the subframes going to the DSP.
