how to check if the system is wide trunking Motorola APCO system

[jensonbut]

Hey guys I'm new on radio solution please go easy on me.I just learned about the concept of site trunking and wide trunking on APCO system particular on Motorola system. My question is how do I know if my GTR8000(base station) is on wide trunking.

cheers!

I guess the simple way would be to program a subscriber radio to alert to site trunking, it will do so every few seconds if the site is in site trunking. Be aware that if site preference is not set to always it may jump to an adjacent site if RSSI is ok, since the radio will prefer wide trunking. If you have trouble with the radio roaming to a wide site you could also program radio with the menu option to lock the radio on the site you are checking.

The other way to check your GTR8000 is with net management / PRNM. Open CSS, establish a connection (GTR8000 multi site base radio, enter zone site and radio number) then connect to it, then run status report screen, click the station status tab, it will then show what trunking status, if the station is control, etc.

Thanks for your reply.
What if I can't access via the PRNM, can I try on the serial port of the GTR8000, can I check from there?There is 2 serial port, which one & How does these serial port work?

I am not sure how to check locally, I have always done it over the network. If memory serves right, there is a check box in the establish connection page for "local connection." I always thought this would be done using the ethernet cable that goes to the site router, but I have never tried it. Maybe the GTR8000 manual, or CSS help, will direct the proper port for local connection. Another option is logs / reports in UEM may show if that base radio is trunking.

Can you open zone watch? If the site is green in zone watch all base radios should be trunking.

There is no real way to check at the base station level what the site as a whole is doing. The best way to check assuming you don't have access to a NM client (or are at the site with no link to the RNI) would be to connect to the active site controller via CSS and examine the status panel. The status display is also a good way to see the health of a site "at-a-glance", though this is more usefull when dealing with a simulcast cell.

Speaking of, a comparator will also tell you whether it is in wide, site, failsoft etc, but only for that particular channel, not the whole site.
