CROSSING AN SDH NETWORK

Both AM200 sections take their timing from the network and both are configured the same. Use the
configurations shown in sections 7.2.1 or 7.2.3.

Note: The SDH network might be configured to provide a PDH path, in which case see section 7.4

7.4

CROSSING A PDH NETWORK

In this example, a PDH network is shown where timing is passed transparently from end to end in both
directions. From a timing point of view, this is equivalent to connecting Master A directly to Master B. To
provide a Master clock to the system, side A should be set as in section 7.1.1 or 7.1.1.2, otherwise, without
a master clock somewhere in the path, the timing will be unstable.
