The present document places the following requirements on the timers described in this ETS:

‑ timer TR1M shall be greater than 35 seconds and less than 45 seconds;

Annex A (informative):
Arrow diagrams

Arrow diagram A1:

The diagram shows MO‑message transfer by means of interlayer service primitives and the actual messages being transferred between the layer entities.

‑ MNSMS‑primitives indicate services provided by CM to SM‑RL.

‑ MMSMS‑primitives indicate services provided by MM to CM.

‑ CP‑DATA is the CM‑message carrying SM‑RP data units.

‑ CP‑ACK acknowledge CP‑DATA reception on CM.

Arrow diagram A2:

The diagram shows MT‑messaging by means of interlayer service primitives and the actual messages being transferred between the layer entities.

‑ MNSMS‑primitives indicate services provided by CM to SM‑RL.

‑ MMSMS‑primitives indicate services provided by MM to CM.

‑ CP‑DATA is the CM‑message carrying SM‑RP data units.

‑ CP‑ACK acknowledge CP‑DATA reception on CM.

Arrow diagram A3 and A4:

These diagrams are repetitions of diagrams A1 and A2 with the modifications being the request for the subsequent MM‑Connection prior to the sending of the second CP‑ACK.
