Digital channels on analog basic?

[Rod Beauvex]

Recently, an old lady I walk a dog for downgraded her service through Charter cable, so now she is just getting straight basic from the wall, no converter box. I had to come set up the channel list. It was mostly the usual analog channels, but I noticed there was a handful of digital channels as well. This was unexpected. Does anyone else have an analog service like this? Do you get some digital channels in basic?
