lossPlanSet
Syntax:
lossPlanSet "transducer", rlrOffset, slrOffset
Change the gain settings on the IP Phone from the volume levels specified
by the TIA-810A and TIA-912. The parameter transducer specifies the
transducer name that requires a gain adjustment: handset, headset, or
handsfree. The parameter rlrOffset specifies the amount of receive-level
adjustment (the level for the IP Phone user), while the parameter slrOffset
specifies the amount of transmit level adjustment (the level for the far-end
user). Values for both are in the range –8 to 8 (in dB). Negative values (–8
to –1) increase the volume (gain).
Enter the command once for each transducer level requiring adjustment.
Adjustments are not cumulative; the last one entered for a particular
transducer replaces prior offset for the transducer.
Enter this command on the node Leader card while it is the node master to
ensure that the data ipropagates correctly to all cards in the node. When
you install a new leader card on a node with modified levels, always enter
the loss plan command on the CLI even if the command was previously
entered on the CLI on another card.
After you enter this command, the gain adjustment is downloaded to
all registered telephones. When phones register, they are downloaded
the new gain values. The gain adjustment is also saved to a disk file
(/c:/config/loss.ini) so the adjusted gains are retained when the card
reboots.
When a node has a modified loss plan (that is, when you use this
command or UKLossPlanSet), a new card added to the node is updated
with the modified loss plan 30 seconds after it boots. Prior to that being
received, calls made by IP Phones registered to the new card have the
default loss plan levels.
Note: If the gain of the IP Phones is raised from the default levels,
those phones can experience increased occurrence of echo and other
audio issues related to the increased volume.
