5.1 SDH Setup and Status
An STM-xx button in the navigation area of the Ports Setup screen gives
you access to the SDH setup for the transmitter and/or receiver of the
currently selected port.
Refer to SDH/SONET switching for switching to SDH.
Synchronous Digital Hierarchy (SDH) is a standardized protocol that transfers
digital signals over optical fiber using lasers. At low transmission rates data
can also be transferred via an electrical interface.
The SDH interface uses the electrical BNC connectors and the optical ports.
