Developed on the basis of the compact peripheral component interconnect (CPCI) standard, ATCA
meets new requirements of the telecom industry. Compared with CPCI,
ATCA possesses the following features: -
Provides powerful processing capability to meet the current
and future requirements. That is, ATCA provides sufficient bandwidth
and loading rate of the processor, and improved running efficiency.
-
Enhances the reliability of the system by separating the management
platform, the control plane, and the service plane, all with a point-to-point
structure.
-
Provides large space in boards. The hot-swappable advanced
mezzanine card (AMC) will be supported in the future. Thus, the embedded
application, server application, and digital signal processing (DSP)
array can be flexibly combined to meet the application requirements
for different capacities.
-
Supports a flexible networking. The ATCA enables the USN9810,
other NEs on the core network, and IMS to share the same platform.
In addition, ATCA supports narrowband interfaces, which simplify the
networking and reduce the investment of the operator.
-
Hardware platform
The USN9810 uses the internal open
standards telecom architecture (OSTA 2.0) platform of Huawei. Based
on the ATCA technology, OSTA 2.0 provides high rate, high reliability,
and high expansion capacity.
The OSTA 2.0 hardware platform
stipulates a series of specifications related to boards and software
for the next generation telecom devices. Based on the ATCA standard
architecture and conforming to the network equipment building system
(NEBS) and European telecommunications standards institute (ETSI)
standards, the platform has the following features:
-
High rate
The high-speed serial data link and switched
structure are used. Thus, the data exchange bandwidth intra-subrack
can reach 2.5 Tbit/s.
-
High reliability
All boards and subboards are hot swappable.
In addition, redundancy is implemented on all key components, such
as power supply, fan, management module, and board of each type. The
reliability of the system reaches 99.999%.
-
High expansion capability
The USN9810 supports addition
of interfaces on the ATCA board and cascading between subracks through
the interface board within a subrack.
-
Well management
The standard management bus is used,
which can manage any part in the system.
-
Software platform
The USN9810 uses the embedded software
platform, namely, carrier grade platform (CGP), which is universally
used by the core network products of Huawei. The CGP has the features
such as cross-hardware platform, cross-operating system, and easy
maintenance.
-
Cross-hardware platform
A uniform interface of the hardware
platform is provided, which implements the operation of upper-layer
applications on different hardware platforms. Thus, the hardware management
is independent of the hardware platform.
-
Cross-operating system
Different interfaces of the operating
system at the lower layer are shielded. Instead, a uniform virtual
operating system application programming interface (VOS API) is provided
for upper-layer applications.
-
Easy maintenance
The implementation mechanisms of the
functions such as operation and maintenance, alarm management, performance
measurement, call and signaling tracing, data backup, board switchover,
and online loading are provided for upper-layer applications.
Easy Operation and Maintenance The operation
and maintenance (OM) system of the USN9810 has the following features: -
Flexible OM methods
The O&M system can be flexibly
built according to the network structure and customer requirements.
Multiple maintenance interfaces are supported, including the interfaces
to the HUAWEI Operation & Maintenance System, the Huawei centralized
network management systemM2000. Through the
Common Object Request Broker Architecture (CORBA) interface provided
by the M2000, more network management requirements can be fulfilled.
-
Maintenance interface combining MML and GUI
The interface
is characteristic of easy and quick operations provided by man-machine
language (MML) in addition to vivid display and easy memory provided
by graphic user interface (GUI).
-
WebUI-based maintenance operation and performance browse
The WebUI-based maintenance operation and performance browse
are added. That is, certain maintenance operations and performance
browse are implemented on the Web.
-
Powerful signaling trace
The USN9810 provides functions
to trace the messages of designated subscribers and the signals on
the protocol interfaces, such as the Iu, Gb, S1-MME, S6a, Gs, SGs,
and Gr. The USN9810 also provides message explanation and filtering.
-
Configuration rollback
The configuration rollback in
batches is supported. Only one rollback point can be set.
- One-key upgrade and installation
-
Software patching in function level
Software problems
can be solved online without service interruption. In addition, remote
operations and rollback operations are supported.
