We have a customer that is remodeling an entire apartment building and has their construction office in one apartment. As the project moves along, they need to relocate the construction office accordingly. They have their telephone and Internet service provided by Comcast using hardware located within the apartment.

The customer now needs us to move everything to the next temporary office location in a different apartment. My thought is that as long as they remain on the same node, we should be able to plug in the modems to any working CATV outlet in the building.

Am I correct in my assumption? It is my understanding that Comcast communicates with these devices using MAC addresses, so the modems should work pretty much anywhere on their network, correct?

Ed,

We had to do the same thing with one of customers several times during the different phases of construction. Comcast didn't actually care that we moved it because I checked with them. They told me that they would have to charge each time they came out to move. We moved it from it's original locations 2 times before it landed in its final destination. I would say you should be good as long as your coming from the same entrance cable and can tap off. I have seen when they are using multiple devices on the cable network they use different .db level splitters (i don't know if that is just something that I've noted and is normal or if that was just what they had on the truck) and that would be my only concern.

I was always told that the modem needs to be as direct a line as possible...connected to one leg of a 2 way from the main drop, and the other leg would feed the TVs.

Jeff that was alway my understanding as well, not that it would not work but speed may suffer

I've always seen it done that way by Time Warner so that's how I've done it.

Ed, is there a way for you to leave the modem in one place (in the basement or other utility area) and just transport the voice and data via twisted pair to each apartment, as it's needed?

Not really Arthur. The apartments only have a three pair feed from the riser closets and we need six. All solid sheetrock.

Hmmm...

As my old Grandma would say, you're S.O.L.

I guess you don't want to set up a short-haul T1 line from the basement to the apartment. Put an Adtran 750 channel bank at each end, and send data and voice over two pairs.

I can lend you the channel banks with FXO and FXS cards, but I don't have any data cards to go in them.

I see no problem with moving the modem as long as it's still within the same physical address. Keep in mind that it's registered to the E911 database. Move it across town and that will be a problem.
