No, its not recommended !

Although VM seem to be doing little about these boxes at the moment there is certainly no guarantee that they wont start doing something tomorrow.

Basically, people are being far to greedy and taking too many chances !

tbh, I dont know if anything is public or not as i've personally never got to play with one of these boxes but disabling talkback shouldn't be too difficult. All of these boxes have a similar circuit for talkback which usually resides in the cable interface module. It usually consists of a return path amplifier chip and an impedance matching transformer.

The trick is to find the RPA chip, google for its datasheet and then take the appropriate action to disable its function.

If you spot a chip that looks likely then google its details. It should become rapidly apparent when you get the correct chip !

except that they aren't blockers - they are attenuators which is not at all the same thing !

An attenuator simply reduces the signal level by some amount. 50dB is a huge reduction but theoretically an engineer with the appropriate equipment could still detect this signal !
