Configuring CEM
This section provides information about how to configure CEM. CEM provides a bridge between a
time-division multiplexing (TDM) network and a packet network, such as Multiprotocol Label

a CEM pseudowire to the remote provider edge (PE) router. Thus, function as a physical communication
link across the packet network.
The following sections describe how to configure CEM:

CEM is used as an element in configuring pseudowires including Structure-Agnostic TDM over Packet
Note
(SAToP) and Circuit Emulation Service over Packet-Switched Network (CESoPSN). For more
