System Background
As metropolitan optical networks are gradually becoming the
focus of communication network development, bandwidth MANs
should be a user-oriented comprehensive platform to provide
data, voice and video services. The convergence layer and
access layer of the MAN involve several types of devices, require
complicated access methods, and have very high requirements
for interfaces. Many operators not only need to provide the
subscribers with TDM-based voice services, but also Internet,
data and leased line services.
The ZXA10 S300 fully meets such needs. The ZXA10 S300 aims
at the convergence layer and access layer of the MAN. It is
capable of multi-NE layer-L2 Ethernet switching, ATM switching,
and TDM transfer, provides E1, STM-1 ∼ STM-16, 10/100 Mbps
Ethernet, GE, POS, and ATM interfaces, and enables self-healing
