Is there any TETRA Terminal available on the market with with multiple ISSI support (done via user profiles, system/personality or something like this)? EADS, SEPURA and ******** radios I come across definitely can't do that.

He-he... I know that Azart can do it with some firmware revisions... :)
Which Azart ? The Russian terminal ?Quote:

Looks like it's limited to DMO only. Can't do TMO.
I have worked with many TETRA terminal and never found this feature sorry.
Same here. Bad luck.Quote:

ISSI is not part of authentication process. ISSI is a thing used for authorization. Anyway, why not? Different networks and different ISSI - what's the problem?
What is the difference being part of the authentication and being thing used for authentication? In my ear it sound like it doesn't make any sense, but it might be just me:confused:Quote:

Also I guess its easier to keep track of all the communication in those networks when they come from different radios versus when they would come from same radio. I don't see much use for multiple issi support in one radio unit since field units normally be part of only one network and then emergency response centers etc have possibility to operate in multiple networks if needed. Having possibility to make like one "master unit" that could access all the networks is not a good idea nor no one even need that.
authorization will mean registration (basic TMO process), while Authentication (which is a paid feature) is part of security.
It just means that you're neither TETRA nor IT specialist.Quote:

My apologies for miss understanding I read your sentence wrong as you might see from my post I thought you said authentication twice, my bad.Quote:
