Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 3: Interworking at the Inter-System Interface (ISI); Sub-part 10: General design, PSS1 over E.1
|Publication Date:||1 April 2020|
The present document defines the transport of the Inter-System Interface (ISI) using PSS1 as transport layer. It specifies:
• the PSS1 signalling used for transport of ISI APDUs; and
• the general protocol mechanism, called ISI Mediation Function which coordinates the communication between TETRA systems.
The ISI Mediation Function applies to any TETRA Switching and Management Infrastructure (SwMI) which supports the ISI.
