Motorola Intelli-Repeaters

How do IR's interface with the overall trunking system? I believe they are used to fill-in poor coverage areas, but will they carry all the talkgroups of the system? Or will they just carry talgroups on which they see traffic on the IR input?

Thank You

Whether a TG appears on a site or not doesn't really have any bearing on a site being an IR or not. What determines a TG appearing on a site is a few conditions. First, the TG has to be permitted at a site. If it's permitted a radio needs to affiliate on that TG at that site. The exception to the rule is a TG can be marked to always appear at a site, or sites, regardless of affiliation; this is rarely done as it defeats the purpose of SmartZone's Dynamic Site Assignment feature, which is used to conserve resources.

An IntelliRepeater is used when a non-Simulcast site is needed. Because of its simplicity it's also used for fill-in.

Wayne,

Thanks for the response. If a radio does not affiliate with the IR, therefore, it will not show up on an IR output voice channel. Is that correct?

I monitor a system near my home where I can hear my local PD and FD TG's only show up on the IR occasionally and briefly. Though, they are on the "main site" simultaneously. And for the balance of their transmissions only on the main site. So I am assuming the user's radio affiliated with the IR for one transmission based on RF coverage.

As Wayne pointed out, for most SmartZone systems if no radios on a particular talkgroup are not affiliated with the IR then the IR will not transmit the talkgroups calls from the IR.

This is done intentionally to conserve channel resources. Channels will only be assigned for talkgroups callsat a site if there are units affiliated on that site with that talkgroup.
