The Motorola DCH100 is a newer (2007) model and the only other model listed as a Standard Def All Digital Receiver. This model has a CableCARD rather than integrated conditional access, (CableCARDs were mandated in 2007 for all receivers).

Your DCT2500 is circa 2003.
But, you can ask for any model receiver you want without subscribing to HD service, Cox should allow this. I doubt Cox will invest in any newer Standard Def only receivers.--
