Figure 391 Remove Tx mute to Node C
6. Activate a Tx mute on Node C toward Node D and activate the R5.1.0 software
on Node C, see Figure 392. The activation of R5.1.0 on Node C does not impact
the Ring status, which prevents any dependency on the time sequence of the
upgrade of the East and West radio interfaces. TDM and Ethernet traffic entering
Node C is lost when the interface toward Node B goes down due to radio
interface upgrade, and is restored when it is back up.
