LEAD = Leased Access. Comcast Atlanta's three are 22 (some areas), 26 (19 in ATL proper), and digital 150.
I suspect Comcast Canton/Cartersville/Cumming (old Adelphia) is using Scientific-Atlanta equipment, while Comcast Metro Atlanta is using Motorola equipment (thus the different digital lineups - Motorola boxes display "To Be Announced" while Scientic-Atlanta uses "No Data Available").
RTN is labeled as "WSBR" with program name "WSB Retro".
The channel should be labeled "RTN" instead, because "WSBR" is cryptic. But Comcast and WSB don't have a top notch relationship. (It took 2+ years to get WSB HD on. WSB has promoted their relationship with DirecTV, but never with Comcast. I suspect WSB-TV's retransmit consent agreement, if that is WSB's status, requires cable systems to add WSB's subchannels at their request, so Comcast will comply to prevent losing WSB-TV).
Instead of callsigns, Comcast labels WXIA-DT2 as "NBCW", WUVM-LP as "AZTEC" for Azetec America, WUVG-DT2 as "TELF" for Telefutura, WATL as "MYATL", WPXA as "ION" and WPBA as "PBA". If they don't follow strict callsign naming convention for all local stations, why not label RTN as RTN.
I would love to know whether WSB-TV has elected must carry or retransmit consent, and if so what are the terms. I also would like to know more about WSB's relationship (or lack thereof) with Comcast.
