Four sub-pills switch between the forms - Trigger (Push SMS), Store (SD admin params), BIP / CAT_TP trigger and TCP trigger - and only the selected one is shown (the two GP forms share their fields). They are delivered differently - the administration trigger is a TLV message for the Security Domain, a §9 PUSH is a C-APDU (`80 EC 01 P2`) for an application that supports BIP/CAT_TP.

-- **TCP** — `03` TCP connection (bearer `35`, transport level `3C` with protocol type 02, destination address `3E` - `21` IPv4 / `57` IPv6 / `F0` FQDN, NAA/APN `47`) or `04` identification packet (sent over an already open channel; the ICCID is used when absent).
+- **BIP channel opening** (`01`) - OPEN CHANNEL COMPREHENSION-TLVs optional; the application issues the proactive OPEN CHANNEL itself;

+- **Identification packet** (`04`) is not a trigger - it needs an already open TCP channel, so the TCP request has an *Also send the identification packet (04)* checkbox that appends it in the same message; `04` also stays in the chain's PUSH row for scripts.
