904 Matrix ETERNITY NE System Manual
Gain Settings
To avoid noise or echo during speech, you must set the speech volume levels on the ports. SARVAM UCS allows
you to set the speech volume levels for the following port types—CO, Mobile, SIP and SLT.
The speech volume levels can be adjusted by increasing or decreasing the Gain Settings provided on each port
type.
How it works
A call received on the CO port can be placed on any of the following ports—SLT, Mobile, SIP. The speech volume
levels differ according to the port type. Hence, on the CO port you must set the speech volume levels for each of
these port types.
In this case, let us assume that the call on the CO Trunk is to be placed on the SLT Port.
Before placing the call on the SLT Port, the system applies the CO to SLT Gain Setting (Receive and Transmit Gain
settings) configured on the CO Trunk to adjust the speech volume level.
When the call is placed on the SLT Port, the SLT to CO Gain Settings (Receive and Transmit Gain settings) on the
SLT Port are applied to adjust the speech volume level.
Hence, you can set different speech volume levels for each port type and the system automatically detects and
applies these gain settings for each port type.
