‑ Priority levels.
Contents:
– the eMLPP priority levels subscribed to.
Coding:
– each eMLPP priority level is coded on one bit. Priority levels subscribed to have their corresponding bits set to 1. Priority levels not subscribed to have their corresponding bits set to 0. Bit b8 is reserved and set to 0.

NOTE: Priority levels A and B can not be subscribed to (see TS 22.067 [5] for details).
EXAMPLE 1: If priority levels 0, 1 and 2 are subscribed to, EFeMLPP shall be coded ‘1C’.
‑ Fast call set‑up conditions.
Contents:
for each eMLPP priority level, the capability to use a fast call set‑up procedure.
Coding:
each eMLPP priority level is coded on one bit. Priority levels for which fast call set‑up is allowed have their corresponding bits set to 1. Priority levels for which fast call set‑up is not allowed have their corresponding bits set to 0. Bit b8 is reserved and set to 0.
