Figure 393 Remove Tx mute to Node D
8. Activate a Tx mute on Node D toward Node A and activate the R5.1.0 software
on Node D, see Figure 394. The activation of R5.1.0 on Node B 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 B is lost when the interface toward Node C goes down due to radio
interface upgrade, and is restored when it is back up.
