System functions
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

protection. ZTE10 S300 enables automatic timeslot configuration
for the traditional TDM service; ZTE10 S300 enables static
bandwidth distribution, and enables dynamic bandwidth dispatch
within the maximum available bandwidth range as specified by
the subnet for the data service. It supports the unified service
management and unified service dispatch by the multi-service
access network (MSAN). Finally, ZTE10 S300 provides a service
transfer platform for the MSAN equipment like the ZXA10 T300
V6.0 integrated access office service convergence unit and
ZXA10 U300 V3.0 integrated access client service processing
unit. Its flexible configuration can meet fully operators’ needs. It
can be networked with the S series of S200 and IST in a mixed
manner, and be networked with the last generation ZXA10-
AS1/AS2 in a mixed manner via the ring network architecture of
the MAN. It is an effective, stable and scalable basic telecom
platform in a broadband MAN for telecom operators to quickly
develop services, unify management and reduce operation costs.
The series integrated access service Dispatching Unit include
ZXA10 S300, ZXA10 S200 and ZXA10-IST. They can be
networked in a mixed way. S300 is usually used for the service
convergence nodes with intermediate and large capacity, S200 is
used for the ONU nodes with intermediate capacity and the OLT
nodes with intermediate and small capacity, and ISU is used for
the small-capacity ONU nodes at the end.
ZXA10 S300 has following features:
Multiple access means
ZXA10 S300, on the basis of the SDN, provides TDM,
Ethernet and ATM interfaces, and supports the access,
transfer and protection of TDM, ATM, and Ethernet.
High reliability
ZXA10 S300 can form self-healing ring , features simple
network topology and high network reliability, requires a
small number of links, save optical fiber resources and can
perfectly meet the optical cable topology structure in the
metropolitan area.
Unified network management
The Network Management (NM) of the ZXA10 S300 can be
integrated into the NMS of the ZXA10 access network.
Standards Observed
The ZXA10 S300 is in compliance with the national standard
in relevant countries, the standards of the telecommunication
industry in China, ITU-T standards and relevant technical
standards.
