GainGen Function
When the digitized voice data is multiplexed together off-chip, the Gain Generation (GainGen) function receives the voice data and adjusts the gain to the appropriate level, depending on the final destination of the voice signal. If the voice data is to be sent over the Internet, a decibel adjustment may not be necessary. If a call is to be sent within the gateway, a standard 6-dB loss may be added to the signal. Regardless of the call's final destination or the number of signals on the bus, the function can easily scale the appropriate gain level with the correct processor input.
