Quidway® NetEngine 80 Core Router

ATM Optical Interface Boards

Overview

In addition to abundant IP network modules, the Quidway

NetEngine 80 core router (abbreviated

to NE80) provides ATM modules to be compatible with traditional ATM networks, satisfying users'

higher bandwidth and QoS requirements for networking. The NE80 supports the OC-3/STM-1 ATM

optical interface board and the OC-12/STM-4 ATM optical interface board.

The ATM interface board implements functions of the physical layer and the data link layer in

network connections. The sequence of bearing/encapsulation from bottom up is as follows: Optical

signals transmit SONET/SDH frames, SONET/SDH frame container bears the 53-byte ATM cells,

and ATM AAL5 encapsulates IP packets or data packets of other types. The interface line board

extracts data packets from this series of bearing and encapsulation and transmits them to the

network after encapsulation and translation processing.
