FinM Deployment Guide Release 4.5.10 3 ‐ 14
Intra Train Handover (ITHO) Update Message Network Guidelines
The Intra Train Handover mechanism discovers that a higher throughput can be achieved
through TMU ‐ B, defined at present as PASSIVE. (TMU ‐ B may be connected to the same TBS as
TMU ‐ A or to a different one ‐ this does not affect the ITHO).
An ITHO is therefore initiated and TMU ‐ B is re ‐ defined as ACTIVE. TMU ‐ B then sends 2 update
messages (marked in blue in Figure 3 ‐ 10 ):
• Update message to wayside core router with on ‐ board router MAC ‐ to update the way ‐
side L2 network of the new data path (same process as in the IBHO update described
above)
• Update message to the other TMU (TMU ‐ A) with the wayside core router MAC ‐ to
update the train L2 network of the new data path.
