    Question SSI2 / SSI3 - what is this?

    Hi all!

    Just analyzed TETRA terminal activity which is officially on duty in this network. I see correspondent GSSI and ISSI plus one more field, SSI2. Googled a bit and found some mentions about SSI2 and even SSI3. But the information is very indistinct and poor. Checked all fields in radio codeplug and didn't found any entries that matches 262152. For me it looks like some parameter belongs to core system controller, billing, etc. But I am not sure. Who's 100% sure what is this and can explain it for me? Or just point me to ETSI pdf where I can get more info about SSI2.

    Thanks in advance!

    Board shows very small picture, but you can see full size screenshot in ZIP attachment. Analysis done by TETRA plugin for SDR#.
