Chapter 1 Overview

Confidential and Proprietary Information of ZTE CORPORATION

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.

The ZXA10 S300 has the following Ethernet service

transparent transmission functions:

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 links based on SDH virtual
containers. The functional block model is shown in Figure 4.
