Zte ZXA10 S300 Technical Manual page 21

The Ethernet service transparent transmission function
supported in the ZXA10 S300 means that any data frame
from an Ethernet interface need no Layer 2 switching and is
mapped to SDH Virtual Containers (VCs) immediately after
protocol encapsulation and rate adaptation. Then, these
frames are transmitted point-to-point via SDH nodes. The
functional block model is shown in Figure 3.

Configurable transmission link bandwidth.
Ensured transparence of Ethernet services, including the
transparent transmission of Ethernet MAC frames and
VLAN tags.
Ethernet Layer 2 switching service
The Layer 2 switching function supported in the ZXA10 S300
refers to data packet switching based on Ethernet link layer
between multiple Ethernet user interfaces and one or more
standalone point-to-point
containers. The functional block model is shown in Figure 4.
