No. He's referencing the original, heavily used, 3600 baud control channel, Motorola Smartzone SNACC system.
There's really only two "voices" that I'm aware that actually matter here:analog and IMBE digital.
Since Motorola's IMBE Astro is the same voice (not control channel) as P25, and I'm not aware of any currently produced scanner that supports any digital voices except the P25 (IMBE) voice, the only scanner/receiver (aside from actual system specific gear) that happens to decode these Astro IMBE digital signals on Smartzone systems is a P25 capable one.
Looking at how the wiki here details the supported voices for scanners, the SNACC system should be labeled as "Analog and APCO-25 Common Air Interface" replacing the current "Analog" now that there are some digital TGs on it.
My guess is these radios are a new stock intended/capable of being used on the upcoming X2-TDMA system.
