DCT or Digital Cable Terminal is the model class of the older boxes - these boxes have decryption ability built in to the main board and therefore a no longer markets or sold because of the FCC mandate of 07/01/2007 (also known as the 707 Mandate) which requires all cable boxes to have "Seperatable" encryption.
DCH or Digital Cable Host is the new model which was designed to meet the 707 mandate. While the boxes have a destinctive visual update (it's been said they were designed by the same motorola team that did the popular RAZOR line of phones)
Given the 6416 was the most evolved of the DCT models the only REAL difference you'll find between a DCT6416 and a DCH6416 is that the DCH has a metal guard sticking out of the back that locks in the Cable card it uses.
Operationally the only difference is the card has to be Validated and our billing systems have to manage the Host box and the card as a combined item. (The Digital Addressable Controller really only cares about the CARD as that's where the Decryption of the signal is occuring)
On the other hand people using the older 6200 and 5200 HD DCT boxes will notice HDMI rather than the DVI port on the DCH6200 HD boxes (non-dvr)
and when they eventually start to phase out the oldest SD DCTs, the updated DCH boxes for SD feature more memory and faster processing versus the older DCT 2000s and 2500s.
If you've got a DCT6416, you're not missing out on anything - if anything you've got the most reliable and advanced box out there as far as DCTs go - and until all the bugs are working out of the DCH system - it's a Tad safer
Now that being said I'm sure someone's thinking "What do you means Bugs in the DCH system"
One of the major changes with the Advent of Cablecards is CCI encryption - this allows distributors the ablility to control what a DVR can and cannot copy and (in theory) it's future level of distribution - it may eventually control how long a DVR may be allowed to retain content.
Generally the default setup for all services in the MSO world is "externally supplied" which means if HBO says you can only copy it one time, it can only be copied one time.
In theory I've really never seen this accomplish much, given that that digital copying has been completely disabled - in practice what happens is certain channels and VOD services may not work if a card is not correctly validated.
This is an issue TIVO SIII users have dealt with for quite a while - in a Motorola world you'll have several numbers associated with a box - the two most important tend to be a Serial Number and a Unit Address.
With a cable Card you'll also have a Cable Card ID number. Once the card is paired with a host (a box or TV) a Host ID (which resides on the box or TV) is generated and there is also a DATA ID on the Card
All three of these numbers have to be correctly entered on a motorola system to validate a card.
At this time only the DCH boxes are truely 2 way host boxes - so if they fail a validation it can be pulled through the system at any time by an Admin or operator... on the other hand other host have to be manually validated (which is a pain in the butt!)
If a DCH box fails validation you'll generally get a screen on any CCI protected channel giving you the Card information - With systems that use Encrypted VOD you'll also get a message saying you lack Validation for VOD
Given the number of DCH boxes in use this does not happen often, but can be confusing as most techs and dispatchers are unfamilar with this scenerio.
There is no extra charge for DCH over DCT
