FM Profile 2
Function management (FM) Profile 2 is supported on primary logic unit-secondary logic unit (PLU-SLU) sessions using LU 0. This profile uses the following session rules:
SLU uses delayed request mode.
SLU uses immediate response mode.
Only single-RU chains are allowed.
SLU requests indicate no-response.
No FMH-1 SCB compression.
Length-checked compression allowed.
No data flow control (DFC) RUs.
No FM headers.
SLU is the first speaker if brackets are used.
Bracket termination rule 2 is used if brackets are used.
PLU will send an end bracket (EB).
SLU will not send an EB.
Normal-flow send/receive mode is full duplex (FDX).
PLU is responsible for recovery.
