Forgive me for using this forum but its the best source I could think 

of.......



Interested in opinions on why digital phone service from the cable TV 

company might be better than service from the old phone company.?

   If the product performs as expected, then there is no

   "better" or "worse" to be considered. We have an integrated

   Cable-Internet-Phone service here and for all practical purposes,

   there has been no observable degradation or enhancement of

   phone service. One thing to consider is the fact that all

   your communication comes in and goes out on one wire. A

   single point of vulnerability/failure for the whole apple

   cart.



   But after about 2 years of using this service, I'm unaware

   of any feature or performance issues that would suggest

   that the change was not a good thing to do.



   In some respects, going the all-eggs-in-one basket

   approach will put greater market pressures on the

   service providers to enhance the scope of services

   offered. I.e, the day is coming that they'll bring

   a glass fiber into the back of your house (or perhaps

   offer a wireless broadband LAN) with greatly expanded

   capabilities. This probably wouldn't happen so fast

   (if at all) if we still had multiple providers with

   a mix of transmission technologies.



   I take that back. There IS a noticeable difference

   albeit a tiny one. When we get a lot of rain, the 40+

   year old telco hard wires get wet and you get some

   crosstalk between subscriber lines and some AC hum.

   The buried coax with RF multiplexing is not vulnerable

   to this condition.

I would add that the cable based phone service needs local AC power to work.

They usually use a UPS for standby power should the power go out. But this

standby time will be limited by the capacity and condition of the back up.

The old style phone service is not dependant on AC power at the premises.

Interesting observations Bob.



One other thing I have noticed while talking (conferencing) with my family

in SoCal and Japan is that Skype running on my laptop has better voice

quality (perceived bandwidth) than using landlines or cell phones.  PC-PC

is best, and any combination of "phone" is not as good.  There also seems

to be less overall delay on Skype to Japan.

Regards,



Matt-

Bob,

    would you mind finding a little more about those dog boxes, if they 

 indeed have propane? gas power? Some remote telecommunication sites use 

 such thermo electric generators and I've read that some thermocouples are 

 available to generate from external exhaust heat of road trucks - you 

 know where this is leading - I wouldnt mind attaching one to my aircraft 

 as a backup power source.


	


   I'm not aware of any thermoelectric products that go beyond

   a hand-full of watts capability. That technology goes back a

   very long way. Here's a small step back in time to when thermoelectric

   power generation became commercially practical technology:

- however they ony seem to supply to certain markets and that doesnt 

include locally.


	


   If your interested in the Stirling engine development

   programs, suggest you visit



http://www.stirlingengine.com/



   That company started here in Wichita by a good

   friend of mine. I have a couple of the earliest

   "Coffee Cup Engines". In particular, check

   out Brent's book offerings at:

   The cable system dog-house is branded "Alpha" which

   suggests it's the product of The Alpha Group. I

   wasn't able to find the model of device sitting

   on my street but here's on example of many

   products described on their website

    The next time our cable guy is in the neighborhood,

    I'll ask him what he knows about our particular

    version.
