Drudge has said he uses ISDN to do his Sunday night show. They're dual channel also. It works pretty well from what others have said.

So, was there no official broadcast at 2 o'clock in Korea? We should at least have that word leaking out.

2B+D. 64 kbits/sec, full duplex, two channels. Perfect for voice broadcast work. Standard voice over the phone is a 2.4 KHz channel. You can expand that to 8 KHz with ISDN. The comrex is probably a compandored approach to squeeze a better quality audio for broadcast through the standard u-Law/a-Law PCM commonly used for voice traffic.
