Summary
This Howto describes the configuration of the volume parameters for user of an IP110, IP200A and IP230
Applies To
This information applies to
- Inca based IP phones (IP200A, IP110, IP230, IP150) version 6.
More Information
Problem Details
In some cases the default parameters are not perfectly matching the customer requirements. To adapt to the customers needs, there are a number of volume parameters which can be tuned.
At the phone, there are two amplifiers, one analogue and one digital, separately adjustable.
Tip! Try to keep down the analogue amplification.
Configuration
The acoustical parameters are specified separately for each component
config change INCA_DSP HANDSET ... config change INCA_DSP HEADSET ... config change INCA_DSP SPEAKER0 ...
All of the configurable parameters given here have separate values for each volume level (1..8, lowest level first), in case of an incomplete specification the last specified value is used for all remaining levels, e.g.:
/uatt_ATT f1,e4,d7,cb,bf is equivalent to /uatt_ATT f1,e4,d7,cb,bf,bf,bf,bf
/uatt_ATT bf is equivalent to /uatt_ATT bf,bf,bf,bf,bf,bf,bf,bf
All parameters for one component must be entered the usual way with one "config change" command, for example
http://172.16.16.128/!config change INCA_DSP HANDSET /afe_arcr_HOC1 4 /afe_acr_atcr_MIC 4 http://172.16.16.128/!config activate
The "config activate" command applies the new parameters on the fly, even if the addressed component is currently in use. Thus the result of a change can be checked on an active connection.
A dump of the built-in parameter is written to trace buffer when the driver is told to do verbose traces by the command line
config change INCA_DSP /mtrace ...
To remove mtrace
:
config change INCA_DSP config write config activate
Look at examples under "Speakerphone Speaker" and "Digital Outbound Direction" for increasing volume at handset, headset and loadspeaker.
Side tone gain
The side tone gain (the volume of your own voice fed back into your speaker) is volume level dependant and available for the handset and the headset only. It is set by the following command flags:
/uatt_ATT <gain1>,<gain2>,...<gain8>
The default for both handset and headsets ist
/uatt_ATT f1,e4,d7,cb,bf,a1,8f,80
The gain settings can be taken from the following table
Gain dB | -0.5 | -1 | -1.5 | -2 | -2.5 | -3 | -3.5 | |
0 | ff | f1 | e4 | d7 | cb | bf | b5 | ab |
-4 | 98 | 8f | 87 | 80 | 79 | 72 | 6b | |
-8 | 65 | 60 | 5a | 55 | 50 | 4c | 48 | 44 |
-12 | 40 | 3c | 39 | 36 | 33 | 30 | 2d | 2° |
-16 | 28 | 26 | 24 | 22 | 20 | 1e | 1c | 1b |
-20 | 19 | 18 | 16 | 15 | 14 | 13 | 12 | 11 |
-24 | 10 | 0f | 0e | 0d | 0c | 0c | 0b | 0a |
-28 | 0a | 09 | 09 | 08 | 08 | 07 | 07 | 06 |
-32 | 06 | 06 | 05 | 05 | 05 | 04 | 04 | 04 |
-36 | 04 | 03 | 03 | 03 | 03 | 03 | 02 | 02 |
-40 | 02 | 02 | 02 | 02 | 02 | 01 | 01 | 01 |
-44 | 01 | 01 | 01 | 01 | 01 | 01 | 01 | 01 |
-48 | 01 | 00 | 00 | 00 | 00 | 00 | 00 | 00 |
Analogue to digital / digital to analogue gain
The external i/o devices (microphone and loudspeaker) are attached to the phones digital voice processor using an A/D converter. To normalize the signal levels (such as the different microphone levels from the handset and a headset), an analogue front end is used. This shall be used to make sure all I/O sources used have equivalent levels towards the A/D converter. The analogue front end is not meant to change the overall volume. This is done in the digital amplifier. So if the phone is e.g. too loud overall, then don’t tweak the analogue front end. However, if e.g. the headset is too loud compared to the handset, then adjust analogue front end parameters for the headset.
Analogue Amplification
As described above, the analogue settings are used to adapt a single I/O source to the overall signal level. Please note that this is normally not required anyway as the handset and speakerphone are already properly adjusted. However, when attaching headsets, some tweaking of the analogue gains may be useful.
Microphone
The microphone amplification is set by
/afe_acr_atcr_MIC <volume>
Where <volume> is in the range of 1..7.
Handset default is /afe_acr_atcr_MIC 5.
Headset default is /afe_acr_atcr_MIC 6.
Speakerphone default is /afe_acr_atcr_MIC 6.
Handset Speaker Volume
/afe_arcr_HOC1 <gain>
Where <gain> is in the range of 1..9 (1 == maximum volume)
Default is /afe_arcr_HOC1 3.
Headset Speaker
/afe_arcr_HOC2 <gain>
Where <gain> is in the range of 1..9 (1 == maximum volume)
Default is /afe_arcr_HOC2 3.
Speakerphone Speaker
/afe_arcr_LSC <gain>
Where <gain> is in the range of 1..12 (1 == maximum volume)
Default is /afe_arcr_LSC 4.
Example for lifting up the volume on speakerphone:
http://172.16.16.128/!config change INCA_DSP SPEAKER0 /afe_arcr_LSC 1 http://172.16.16.128/!config activate
Digital Amplification
Digital gains are used to change the overall volume of a phone. This is somewhat cumbersome. Then again, it is rarely required.
Digital Inbound Direction
Digital Inbound increase/decrease the volume from your own speach both to the remote party and the feedback to your own speaker.
/afe_IFG1 <gain>
Handset default is /afe_IFG1 32f5.
Headset default is /afe_IFG1 47fb.
Speakerphone default is /afe_IFG1 392d.
Digital Outbound Direction
Digital Outbound increase/decrease the eight volume steps you use for manuel adjusting with arrow keys on the phone. One value is given for each step.
/afe_IFG2 <gain1>,<gain2>,...<gain8>
Handset default /afe_IFG2 036c,066c,096c,136c,166c,196c,1ca8,2027.
Headset default /afe_IFG2 036c,066c,096c,136c,166c,196c,1ca8,2027.
Speakerphone default /afe_IFG2 196C.
Example for lifting up the volume on handset and headset:
http://172.16.16.128/!config change INCA_DSP HANDSET /afe_IFG2 0519,0814,0ccd,1449,1b0d,2027,3215,4027 http://172.16.16.128/!config activate http://172.16.16.128/!config change INCA_DSP HEADSET /afe_IFG2 0519,0814,0ccd,1449,1b0d,2027,3215,4027 http://172.16.16.128/!config activate
The digital gain settings can be taken from the following table
