Dial Up Modem Sounds: V.32ter
Thanks to @FairPlay137 for suggesting an 'oddball connection standards' series! Here's V.32ter, though it doesn't really sound all that much different from plain old V.32. Still fun to see it connect at 21600 though, especially since most modems seemed to only do 19200 with this sort of 'overclocked' V.32.
Upcoming modulations: X2, K56Flex, and Telebit Trailerblazer PEP
If there's something else you'd like to hear, leave me a comment and I'll see what I can do.
Originating modem: US Robotics Courier V.Everything
Answering modem: US Robotics Netserver/8 I-Modem
Call path is as follows:
Courier V.Everything -- FXS port on Cisco IAD2431-16FXS -- PRI port on VConsole 8BRI-U-MOD-2PRI -- Dialogic Diva 4BRI-8 in an Asterisk server -- VConsole 8BRI-U-MOD-2PRI -- US Robotics Netserver/8 I-Modem
The Asterisk server records the call, putting the caller in the left channel, and the answerer in the right.
