Smartnet trunking miminum channels

Will a Smartnet system continue to trunk if only the CC and 1 voice channel are available? Or will it go into Failsoft?

Thanks!

As long as their is a control channel, the sys won't fo into FS. I assume your talking about a sys that is already in operation?

a single site Smartnet will continue to trunk so long as it has a CC and 1 voice. a simulcast system will go to failsoft if it loses more than 50% of it's repeaters UNLESS they are either turned off via SMT or ALL buttons match on all TIB/RTIB and RIB cards. in other words if you have a 5 channel simulcast system and 2 channels are down due a problem if you punch a 3rd out on just 1 card it will go to failsoft approx 15 mins later. been there, done that!

Actually there is a configuration that will allow a single channel.
The control channel will become an audio channel and then revert to passing control information once the channel isn't being used for
a conversation

That is what I am trying to do on a VHF set up. Although I have been unable to bring up the control channel. Any ideas on why I can not get a control channel up and running? Right now the repeater only works in failsoft mode.

Not sure on the config.
It would need to be configured in the zone controller and not locally at the IR configured quantar.

I only know this exists, and a high level of how it works. Unfortunately I don't know how it's configured, only that the station sits as a control channel
until someone affiliated to it keys up. At that point the zone controller assigns the control channel as a voice channel and quits sending the control channel data to it and
switches it to V.24 ASTRO CAI.
There maybe some version specific stuff going on there as well.
Also not sure what versions support it, only that some did.

Thought a bit more on this and have a few questions.
First, do you have all the equipment to do this?
To setup a trunked system, you re of course going to need a station for each channel.
Beyond that, you will need trunking controller. The IR station control board will allow some site trunking if configured correctly, but you need a Zone Controller to begin with for it to get the
trunk configuration from.
Point is that just a stack of Quantars is NOT going to allow you to build a trunked system.

Also, where are you sourcing your V.24 audio from?

It's called "Voice On Control".

Similar to a GE SCAT site.
