The Project 25 Inter RF Subsystem Interface (P25 ISSI) is a non-proprietary interface that enables RF subsystems (RFSSs) built by different manufacturers to be connected together into wide area networks so that users on different networks can talk with each other. The wide area network connections using the ISSI provide an extended coverage area for subscriber units (SUs) that are roaming. The extended coverage area is important for public safety first responders that provide assistance in other jurisdictions during an emergency.

It is a big deal. However, it is a technical/logistical pain in the rear to implement and that is only after all of the political hijinks involved. Imagine something like that in an area where police doesn't even talk to fire who doesnt talk to public works, etc. It can be an amazing thing if it is allowed to be. I expect much more ISSI rollout once the State Moto system starts coming online. TT

We have a Motorola P25, a Harris OpenSky, and a Harris P25 system all talking to each other across ISSI.
It works very well...

Except when the Opensky sounds like crap coming across LECOMM.....

Except when the Opensky sounds like crap coming across LECOMM.....

When does OpenSkam ever sound good?

Agreed!

Actually the core to core connectivity sounds really good between the three.
OpenSky is just slightly lower in volume, but it doesn't have the compression issues like what was heard previously.
