This is one of the reasons we left Comcast and signed up with AT&T U-verse in 2009. Comcast came in and took over Tele-Media/Adelphia of Western Connecticut then immediately began to remove some of the New York area stations that we've been watching since cable debuted and even before that via antenna. To the contrary, AT&T offered us all of those old channels back as well as some new ones, so it was a no-brainer for us to dump Comcast. Even though there were some highly publicized problems with the transition from AT&T to Frontier, it's a far superior product than what Comcast offered/offers. Even today when I visit friends and relatives who still subscribe to Comcast, I can't believe how they're still using 90s-era cable boxes, graphics, etc. But that's besides the point.
To answer your question... I'm not sure how Frontier is operating their lineups in Connecticut right now, but AT&T split the state into the two markets of NYC (Fairfield County) and Hartford-New Haven (the other seven counties). The Hartford-New Haven market was then further split by county with New Haven County receiving the majority of NYC market stations, followed by Litchfield County, then Middlesex. I think they use the FCC Significantly Viewed (SV) out-of-market station criteria to decide who gets what. For Hartford, Tolland, Windham, and New London counties, all of these NYC stations are blocked out with the exception of a few PBS affiliates. So even though the out-of-market stations are listed in the Hartford-New Haven channel lineup pamphlets they hand out and put on their website, these stations won't actually show up on your TV unless you're in the right zip code. For whatever reason, they don't offer the Springfield, Providence, or Boston market stations like the local cable franchises do.
Another interesting thing is that while it was AT&T's policy to not pick up local digital sub-channels, Frontier began adding them as soon as they took over in November 2014. I'm not sure if this was because it's easier for Frontier to do as a local company (based in Norwalk) or if it was to placate customers after the transition debacle last year. Either way, it's refreshing when a company is adding channels instead of taking them away, so no complaints from me!!!
Since I live in the area and have family and friends in both counties, I can confirm the local lineups for you in Fairfield and New Haven counties:

The following lineups are what AT&T was using as of 2012. I can't confirm them at this time, but I doubt they've changed much (with the exception of new digital subchannels that were recently added). Unfortunately, Frontier doesn't allow you to check the local lineups by zip code which was a feature on AT&T's site.

Representatives from Frontier, the largest landline phone provider in Connecticut (they took over when AT&T left the state), had representatives at a U-Conn college hockey game in Hartford's XL Center. Anyways, they handed out these pamphlets, which showed their available TV packages. The cluster of "local channels" in their Hartford/New Haven channel directory is amazing.

To be fair, the directory may be meant for the entire Hartford/New Haven TV market, which is the state of Connecticut minus Fairfield County. I'm not aware of a single cable provider here in Hartford County that carries a New York City market station. The last ones we carried were WWOR and WPIX. The Syndex rule killed them first, then the old WB and UPN networks did the rest. (Hell, we only receive PBS from the even closer Springfield, MA market!)
