Since the 2500/6400 STB specifications do not include any NTSC or ATSC tuners, then it seems impossible that the STB even sees analog channels 2-49. It expects digital QAM signals, and/or IP data. So it obviously must start over by requesting these low channels via QAM, same as any other channel.
Short answer: They are digital when viewed via the STB
