- Assuming that they use some sort of digital transmission on the coax
- (which is not altogether unreasonable), it would not be difficult at
- all to separate calls. I would be more concerned about the fact that
- anyone else on the same coax segment would be able to tap in and
- listen to your calls, unless they use some sort of encryption.
