Re: [Repeater-Builder] dispatch centers run through the internet
try again. I am a network engineer and I can tell you all it takes is one mistake or routing loop extended power failure etc and your down for a while. Anyone who would even think about doing this over the internet needs their head checked. Ask yourself this question... If your power goes out at home you have comcast digital voice (that goes over the cable modem) and someone robs your house.. What does your alarm do? Nothing! it cant call out because the power is out. VoIP is not a technology that anyone should be relying on for LIFE SAFETY things. the standard SLA on a T1 connection is 4 hours. (and it should be since it costs $4-500/month) realistically they aren't going to fix it until they're 4 hours are up. Home/business DSL connections typically have no SLA or it isn't worth the toilet paper it is printed upon. Its been proven multiple times in the last year (san francisco fiber cut, deep sea fiber cuts, turkey stealing youtube's ip space etc) that the internet is not 190% reliable. You have to remember that you may have a competent admin but you are just as vulnerable if someone else does not have one. One other thing.. 99.99% of VoIP applications use UDP which is a connectionless protocol. meaning that the side sending it has no clue if it got there. Simply put it either gets there or doesn't and you have no idea which. This is a bad bad bad bad bad bad bad bad bad idea. No insurance company in their right mind will touch this. I'd heard that the NFPA is also looking at banning VoIP's use for fire alarm systems. --Don On Jan 4, 2010, at 4:47 PM, Jed Barton wrote: exactly what i thought.

The bottlenecking you might experience with facilities you cannot (do not) control can (will) be the downfall of such a system - unless a SLA can be gotten. A SLA is a service level agreement in which a company guarantees connectivity - to some degree. The more reliability the agreement extends - the higher the cost.

Re: Pagers in 2009 - why? (was: [Repeater-Builder] A desense issue)
There are a LOT of professional people (myself included) who don't regularly carry a cell phone. I have been known to leave my cell phone in a lot of weird places. I have a lot of problems with the reliability of cell phones not being able to send a message via a dial up modem isn't alluring to me. (there are a lot of reasons computer people need to do this) I also have the option of ignoring the pager versus a cell phone. Doctors for one really do not like cell phones.

Playing with my rather deaf scanner, in a rather low-population area, I hear almost no pager traffic - enough that it could easily all be placed onto a single channel or thrown onto a cellular network.

At one of my repeater sights, I have a 220 repeater, a 440, and a 900. Also, there is a paging transmitter about 3 feet away from all of this. Here's the issue. The paging transmitter is desensing both the 440 and the 900. The 440 repeater is a kenwood tkr850, and the 900 is an msf5000. I'm running a set of 4 cavity wacom cans on UHF, same for 900. The paging transmitter is transmitting on 152.6. We've watched it, and there is no doubt that the paging transmitter is the problem. The transmitter is a Glen Air. We can shoot a weak signal in to the UHF repeateror the 900 with the service monitor. That weak signal will get very strong as soon as the paging transmitter unkeys. We even went to the extreme of getting a filter from par electronics to knotch out the 152.6, but na, didn't work. As if this isn't bad enough, the antennas for the 900 and the 440 are only about 25 feet apart horizontally, it's as far apart as they can go. Any thoughts guys, anyone ever run in to this situation?
