Advertisements I have 2 Tivos on Optimum. Recent changes caused problems on lower channels, and they installed a tuning adapter on 1 Tivo that solved the problem. (He only had 1 TA on his truck.) Today I went to the Optimum to pick up a TA for the 2nd Tivo, and I got home and learned they gave me a DTA, specifically an Altice DTA-1WAY. This thing seems to be a type of Set Top Box. It does have a serial port, although no serial cable was provided. Is it possible that it works as a TA too? Or did them simply make a mistake?
