Thanks for replies!
So,
One i.e. DTX works on the basis of presence/absence of speech.
while the other PC works on the distance.
Both effects the Tx Power of MS/BTS.
DTX just reduces the power to a default/threshold while PC has a “range”.
One thing i wonders if both these features have such a wide range of benefits then with what objective the vendor or standard have provided the options of ” Disable” for them.
