Techniques are provided for signal translation in a hybrid network environment. In one example, a first provider edge node obtains a connection status indication from a first one of a second provider edge node via a packet switched network or a third provider edge node via a time-division multiplexing transport network. The first provider edge node translates the connection status indication between a packet switched network format and a time-division multiplexing transport network format. The first provider edge node provides the connection status indication to a second one of the second provider edge node via the packet switched network or the third provider edge node via the time-division multiplexing transport network.
