7845C in conjunction with a DSC 5020

In order for the 7845C to report CID, you will need to replace the DSC

5020with an Ademco panel. Then you wire the 7845C across the keypad bus, then enable ECP reporting on the Ademco panel. Otherwise you are stuck using the single channels for generic reporting.

Do you really think they're going to shut down the AMPS service?

I don't.

It would seem both you and I are the ONLY people I know who think this way, the deal is the providers have the option of turning it off but cellular backups are a very minor part of that network. I think much of the rush is the current AMPS equipment manufacturers have to assume the worst case scenario and figure it will turn off.

In reality it may be years before it goes away if ever, I personally would rather move to GSM anyway since it does offer some enhancements

I can understand that they'd like everyone to stop buying the old equipment and start buying the new so they can get up to speed in manufacturing and also get all the bugs out. And also, the longer AMPS stays around, they'll have to dedicate technical support for it. If they didn't contribute to the rumour mill, that it was going to end, no one in the field would take much notice and wouldn't do anything until the equipment in the field stopped working. The other thing is, they want the centrals to begin investing in the new equipment as soon as possible. There's a learning curve and there's always a shakedown period for equipment and procedures. May as well get everything rolling now instead of experiencing a mad scramble and lull in sales when the sunset occurs.

I think telcos will just let the towers that are working continue, with only minor maintinence, until they stop working. Metro areas will stay up longer because of the abundance of towers. But they're not just going to turn it off at a specific time.

What I expect will happen is that the cell providers will simply stop maintaining the AAMPS stuff, and it will eventually fade away. js

In the Big Metro areas look for that to happen sooner than later... Analog channels only allow a single call per pair (input/output frequency) at any given time. Digital can handle (estimate) 10 calls per pair, that equals more revenue for the telco. The revenue side of things is the big motivator to kill AMPS, they could care less about the alarm guy's problems, after all, we've been warned in advance. Just my 1/2 cent, Russ

Could be, supposedly they want to use the bandwith for something else tho
