SPE: Synchronous Payload Envelope

Synchronous Payload Envelope(SPE) is the payload carrying portion of the Synchronous Transport Signal (STS) in SONET. The SPE is used to transport a tributary signal across the synchronous network. In most cases, this signal is assembled at the point of entry to the synchronous network and is disassembled at the point of exit from the synchronous network. Within the synchronous network, the SPE is passed on intact between NEs on its route through the network.
