Just wanted to share some pics of this awesome headend in working on building in my office.

Got a 4 foot rack from P10 and built a custom top to hold the monitor and keyboard.

I added a 19 inch television connected to a Technicolor DTA to monitor the feed on the Com2000.

Also added a mini computer and a keyboard and mouse to provide onsite access to the Com2000.

UPS battery backup for surge protection.

Also built a custom board for all the SWM switches.

All I need to do to install this is drop 4 lines from the Dish, hook up my main feeds to the rooms, connect to the Internet for remote access and plug it in.

Being the Luddite that I am & not really understanding what I am seeing, would you ever use fiber optic cable or does it just depend on the particular installation? Also, what particular channels would they get from that set-up?
 
A Nice Com 2000 System

4 lines from dish to Polarity Locker (5 power inserters to each of SWM + Locker)
Then split 4 ways to 4 SWM-16
6 of 8 SWM outputs to 6 COM 46 8 channel blades
2 QAM 6 modules so could have up to 24 HD streams or 96 SD streams or some combination that apparently is 48 Channels
Distribution over RF with Technicolor DCI401MCS Pro Idiom encryption
RF combined by Holland HCG 24 1GH combiner and amplified by Perfect Vision PVCA 3051RK distribution (30dB,54-550MHz) amp (to end user rooms)

System managed by Dell micro computer
APC UPS unit
Holland Power Strip

A picture of the back to see the other RF Connections would be appreciated. :)

Anything else?

All the RF connections are on the front
 
Are there not RF connections on the Back Plate of the Holland RF Combiner??
Also there appears to be a splitter or something dangling out back on the last picture.

Just trying to grasp all the connections
Thanks

Looks nice :)

That said, aren't a number of hotels going to a directly distributed model? A number of hotels I've checked into recently actually have a full-on D* guide complete with the same channel numbers I get at home, and special in-house hotel channels... it's actually pretty slick.

Is it still a lot more expensive to have a D* receiver for every channel plus a modulator vs. a cheap receiver in every room?

Just curious is all... I don't know too much about the whole MDU business. I just know that getting the full D* experience when I've been going to hotels lately is pretty slick and wasn't sure how it worked... I'm assuming this setup is more for a rack room with receivers with each channel sent as a linear regular channel to each room?

i know its probably irrelevant, but the plastic caps on the PI's are driving me crazy lol.

otherwise looks sexy.

There are 2 ways to do a hotel. Either do what's called a DRE where they load special software and put a receiver in every room. Or do a headend like this and distribute 48 channels over regular coax.

The break is around 125 rooms.

So for hotels less than 125 rooms then it's cheaper to put a receiver in each room. If there is more than 125 rooms, then this makes more sense.

Ideally a receiver in each Tv is ideal as it gives you more flexibility, however sometimes it's impossible with the existing wiring or if the hotel is concerned with theft then a system like this makes sense.

Once you configure the headend, this is way less labor intensive to install. Most of these can be done in a day or 2 where as a receiver in each room can take a few weeks for a hotel with lets say 109 rooms.
 
Nice and interesting install ...

Few questions. ...

If I understand the COM2000 system correctly. I notice that the QAM6 modulators' channel indicator lights have all three lit for the top module card and only two on the lower one. Which would mean 10 or 12 channel operation for the top module and 6 or 8 for the bottom one. Considering the indicators show the QAM channels in groups of four and counting by two from six channels per the two channel software upgrade key purchase ("SWQAM2") to a max. of 12 QAM channels per module.

So how many actual QAM RF channels are there on each module in this setup?

Also, I assume that even though it is built as a "combiner" by Holland, since it's passive it can actually be used in reverse like a big 24 port "splitter" with the input from the Perfect Vision distribution amp. Giving you up to 24 ports as main feeders to the RF distribution network of the Hotel rooms?

And lastly, as the previous poster asks. I suppose it was a cost issue in choosing four paralell SWiM-16s instead of say two cascaded SWiM-32s and thereby simpler cabling with the same two spare SWiM feeds left over as well?

It's 3 HD channels per QAM channel, so we are using a total of 16 RF channels to deliver 48 HD channels.

Technically there are 49 channels as the first RF channel has 3 HD plus an SD Channel for the guide.

The 2 SWM 16 is cheaper than the SWM 32
 
if you needed to get the 95w sat for some reason would you simply add in a 5th line the same way the primary 4 are? love looking at gear i havent seen before :)

I would imagine essentially yes....

A fifth coax line from the linear LNB on the 95W dish to one of the two available available flexport connectors on the DTV6PWRPOL-02 polarity locker. Then the output from that unit to another 1 x 4 splitter (for a total of five now mounted on that board) to feed one of the flexports on each of the four SWiM-16s
