I had RCN at an apartment I used to live in. Telephone was regular old telephone, with the internet access via cable. We got the whole package: telephone, cable TV, and internet via cable modem. I was satisfied with all the services. There was a gitch or two with installation, but they squared it away. There were occasional glitches with service (seems our external connections at the apartment weren't waterproof among other problems), but they got everything fixed and in satisfactory condition promptly.
