SSI&TSI Dialing Rules
In the TETRA system, subscribers are distinguished by different identities. Each subscriber is assigned
with a unique short subscriber identity (SSI), which serves a part of the TETRA subscriber identity (TSI).
And TSI is generally composed in this way: Mobile Country Code (MCC) + Mobile Network Code (MNC)
+ SSI. To initiate an individual call, please dial the SSI or TSI in compliance with the rules below.
