4.5.1 Traffic architecture
The Ethernet expansion is primarily based on the functions of the SDH Core
Processor (SCP). The latter provides the functions required for data
processing and switching.
The following drawing gives an overview of the traffic architecture and
connections between two EoSCU modules and the PDH kernel of the XMP1
system.
