Data Sheet 1998-07-01
Report the audio mode or operation per the bits as defined in the command options word
above for the data in this packet.
5. Volume Status:
Report the gain on the analog input and output. Defined as in the command volume word
above, i.e. 0 is the minimum volume, and 255 is the maximum.
6. Error Conditions:
Set in response to an error, either in the command sequence or an internal error. All zero
indicates no error.
6.2.1.4
Like stated before, there is a delay of three times the frame length (default: 30 ms)
between the transfer of a new control block from the host to the JADE AN and the new
settings being reported in the status data (transferred from the JADE AN to the host) due
to the internal buffering pipeline of the JADE AN. This pipeline is independent of the
chosen compressed audio protocol (inband or outband). Therefore this chapter is
applicable to
Section 6.2.1.2
and
Section 6.2.1.3
. In case G.723 is used it is
recommended to use the inband protocol due to the fact that packet numbering
information is needed on a 10 ms basis. The packet numbering information is included
in the inband protocol header, thus there is no need to request additional status
information from the JADE (see
Chapter 6.2.1.1
).
Table 25
shows the pipeline behaviour switching from neutral to G.711 and vice versa.
