Comcast DTA Adapter Summary
by Vaughn Aubuchon

The Digital Transport Adapter unit is initially free. But in other parts of the country, a few months after the DTA installation, they charge a $1.99 per month rental fee for each unit.

There are AT LEAST 15 different Comcast DTA boxes, with different manufacturers, part numbers and appearances. They all function differently, as well. Expect issues with this mish-mash of devices. Mine is a DCI105COM1. Only Comcast knows which devices are assigned in each area.

After the Comcast "digital upgrade" in your area, installing a DTA box results in many missing channels.

Disclaimer:
I hope there are no errors. Please report any errors that you may find. All data was found on the public Internet using Google and Wikipedia.

I made this DTA summary page because -

1. I could not find anything like it on the Internet. Trying to identify DTA boxes is like pulling teeth.

2. I wanted to provide a reference index for further research.

3. DTA units sold on eBay only give the part number about 1/2 of the time, and frequently provide no front panel photo - very frustrating.

4. Comcast is extremely stingy about releasing any DTA information. On their website, they show JUST ONE DTA device, which they don't even identify. They actually cover up the part number on the back. Although they offer manuals for 20 different set-top boxes, they offer nothing for DTA devices. Incidentally, my set-top box is NOT one of the 20! So, there AT LEAST 21.

The strategy is to hide ALL DTA box information from their customers, for some reason. Maybe, because there are too many devices, and "John Doe says his xxx model is by far better than the zzz model of Joe Jones." Endless upgrade demands? Just a guess. And the logistics of supporting every device in every service area would be very difficult.

"Standard operation" evolves as new functionality features are added. Later devices may work better than earlier devices (added program guide, greater stability, HD functionality, etc.). OR WORSE, depending upon future specific channel exclusion decisions.

The DTA is designed to be a "cheap set-top box", with highly reduced features (limited channels, no HD, no on-demand, etc.) from a "full-featured set-top box".
