RE: [Repeater-Builder] Re: ROIP interfaces

Look at the chips used in common ATA I like the PAP2T from Linksys (now
Cisco) .

 

It's just like any other interface use the off hook and ring or reverse
battery like your E&M 

 

On the "Trigger Base" you could configure the ATA for "hot dial"  where it
would connect upon off hook.  

 

Hope this helps

 

Robert.

Hi Walter, 

Actually we are evaluating ROIP products for a major dealer network
where my job is purely RF engineering for OEM compatibility.

Granted, I am casting a rather wide net here on a fact finding mission to
see if the group is aware of any other brands that I had not covered. As for
pricing, we will be dealing at OEM level, so its a volume issue as well as
features and performance.

 

In NZ we refer to a trigger base as a semi duplex radio (On Mobile
Frequencies) that is mounted at a fixed location. Often these are line
controlled via E&M, or in our instances ROIP.

 

Hope this helps?

 

Regards

 

Gareth Bennett

What do you consider a "reasonable price"?
And what features are you specifically looking for them to have?

BTW, what is a 'trigger base'? A control station?

Here in the states, the legal term for those is 'control stations'.
It's not 'semi-duplex', it's 'half-duplex'. 
2 frequencies, receiver mutes during TX.

But you STILL haven't answered the main part of the question:
What features at what price point?

BTW, you might also want to ask this on the 'LMR' 
and 'PrivateWirelessForum' lists where commercial radio shop types 
hang out. Make sure you give the answers to my questions when you do, 
or they'll ask the same things.

You should also look at

ahhh...probably what we lazily call "full-duplex" but in reality it
allows 100% monitoring of the receive frequency even while
transmitting locally intermittently, usually requiring headphones ;-)

It amazes me what I can learn even after being licensed 43 years...

Thanks...

I guess it's my turn to ask...what's a "...semi duplex radio..."?
