capacity plus time out timer

[SAFFA]

Hi.

We are considering putting up a capacity plus system. I want to be able to limit the talk time of certain talk groups on the system.

I've looked at the software and the only timer I can see is a time out timer on the repeater, issue with this is that when the timer times out it shuts the transmitter down and thus both time slots end, which will interfere with other groups on the other time slot.

Is there another way perhaps of limiting the talk time?

What you are looking for was, in the days of community repeaters, known as a "hog timer.". In substance, if tone A accumulated more airtime than any other tone during a given window, it would be locked out for a timer interval. Lock out would reversed either by passage of time (expiration of the timer) or by accumulation of airtime by another tone.

I have no idea whether the concept of hog timers has been ported over to trunked systems.

Hytera DMR radios can do this. There is a 'Rent' option in the CPS that limits/sets the airtime the radio is allowed to use. Might be worth a look....

Or are you referring to limiting the time of each transmission? If so you need to look at the TOT & TOT Delay settings for the subscriber units themselves, not the repeater. This is found in the TX settings for individual channels.

Correct, I'm looking to limit the talk time of a talk group to say 2 minutes per conversation between all subscribers in that group.

Reason for this is so that one group doesn't hog the time slot all day.

As mentioned earlier, this requirement is similar to a community repeater hog timers. In fact this system will be replacing existing comreps.

Limiting the timers on the subscriber radios can work to an extent but is not the best solution.

have you considered mpt1327

Instead of inventing the wheel all over again, just add another repeater for more capacity ?

yes, the hytera DMR tier II either single repeater or single site Extended Pseudo Trunking can supply time out timer. but among all digital multiple sites full trunking systems, i wonder whether is such a TOT, maybe because it's not essential.
