1) Control
A microprocessor regulates timing control between the PCM bus and the
module, controls message input and output and generates the audio signal re-
quired for impedance monitoring.
2) Codec
The codec converts the incoming digital signal into analogue LF and passes
this to the opto-coupler for potential separation.
3) Digital Amplifier
The digital amplifier amplifies the potential-separated LF signal.
The operating voltage of 48 V required for this is fused.
4) Filter
The low-pass filter filters the amplified signal and passes it on to the output
transformer.
