CPCI Platform Structure
Centralized power supply: The UPWR supplies power for all boards in a subrack.
Dual CPCI (compact pci) buses (that is, resource-sharing buses A and B) with the bandwidth of 2×2Gbps
Ethernet dual-platform and dual-star architecture
Master and slave serial buses
H.110 bus, providing switching capability of 4096 timeslots and 256 Mbps bandwidth
HUAWEI TECHNOLOGIES CO., LTD. HUAWEI Confidential Page 8
Limitations of the CPCI Platform Low scalability
Complex bus types and limited bandwidth:
CPCI bus: 2 x 2 Gbps
H.110 bus: 256 Mbps
Ethernet bus: 24 x 100 Mbps (in spite of expansion) Limitations related to the power supply, structure, and heat dissipation: The maximum power consumption of
a single slot (50 W) constrains the performance improvement of boards. Not hot-swapping sub boards
Low reliability The bus structure has inherited faults and potential single-point failures, for example, centralized power
supply, CPCI bus, and master/slave serial bus The device control flow cannot be separated from the service flow. This may cause security problems.
Non-authentic Open Standard Platform Carrier-specific standard: Expanded with multiple private interfaces based on the original CPCI standard (for
example, Ethernet bus, H.110 bus, back board size, and main/slave serial port bus) No standard open software interface; tight coupling of hardware and software High lifecycle costs
HUAWEI TECHNOLOGIES CO., LTD. HUAWEI Confidential Page 9
ChallengesWith the development of the telecom industry, carriers are increasingly having higher requirements related
to telecom devices, especially in the following aspects:
Simplicity: The platform should be capable of simplifying the design, manufacture, test, and application of
network devices.
Capacity: The platform should provide sufficient bandwidth, call rate, processor loading rate, and operating
efficiency to meet the current and future requirements.
Performance: The platform should be capable of supporting short delay and call setup duration and providing
high service performance and QoS.
Reliability: The reliability of the platform should reach 0.99999.
Serviceability: The platform should be capable of providing simple, strong, and cost-saving OAM&P.
Security: The platform should be capable of protecting key services from being intercepted and against
Hacking.
Time to Market: Time to market for a new product should be shortened. (purchasing boards, subracks,
Middleware, and APIs from other vendors to reduce development workload)
Cost: Lifecycle costs should be reduced. (software and hardware architectures can ease the multiplexing among
different products and reduce development workload)
Regulatory Considerations: The platform should comply with international specification and standards.

Each SWIA provides one BITS interface and two 8-kHz line clock interfaces. After the SWIA receives a BITS clock source, the BITS clock source is divided into two sources in the SWIA. One of the sources is used for the current board and the other is used for the corresponding standby board. Therefore, from the view of the clock module, each SWIA can provide a maximum of two BITS lock sources and two 8-kHz line clock sources, that is, four clock sources.

Signal Flow of the KVM Over IP
In the ATCA platform, each UPB functions as a server, and the KVM over IP provides a remote KVM function. With the KVM over IP, you
can access to the information of any UPB (a maximum of eight boards at the same time) in any subrack over the OMC interfaces provided by
the OMU.The UPB exchanges the VIG interface information and KVM analog information with the SMM through the IPMB bus. The SMM then packs
the information to IP packets and sends them to the local maintenance terminal through the OMC interface provided by the OMU board.

HUAWEI TECHNOLOGIES CO., LTD. HUAWEI Confidential Page 85
Answers How many types of signal flow are provided by the MSOFTX3000 OSTA2.0 platform?There are four types of signal flow: IPMB bus signal flow, Base plane signal flow, Fabric plane signal flow, and TDM bus signal flow.
If the hardware of a board is faulty in the MSOFTX3000 OSTA2.0 platform, how is an alarm generated for this failure?The faulty board generates an alarm and reports the alarm to the SMM in the subrack through the IPMB bus. The SMM then reports the alarm to the OMU through the Base plane.
In the MSOFTX3000 OSTA2.0 platform, how is the clock distribution among the narrowband clock subracks implemented? How is the narrowband signal flow implemented? The SWI in subrack 0 generates the internal reference clock after locking the external reference clock, and then delivers the internal reference clock to the SWU in subrack 0. The SWU then delivers the reference clock to each ETI in the current subrack through the TDM bus. For the clock distribution among subracks, the SWU in subrack 0 delivers the internal reference clock to the SWI in each expansion subrack through the Base cascading interfaces. The SWI then retracts the reference clock and delivers it to the corresponding SWU, and the SWU is responsible for delivers the reference clock to each ETI.
After being exported through the E1 interface of the ETI, the narrowband signaling is processed for MTP1 and partial MTP2, and then delivered to the corresponding UPBs for other processing.
HUAWEI TECHNOLOGIES CO., LTD. HUAWEI Confidential Page 86
AnswersIn the MSOFTX3000 OSTA2.0 platform, how is the time
synchronization implemented?
The time synchronization is implemented through the Base bus. The OMU board
synchronizes time with NTP server through the NPT interface provided by its
corresponding back board and stores the time in the RTC sub board in the back
board. The time provided by the TRC sub board is considered as the system
time of the MSOFTX3000. All the modules in the system synchronize time
through the Base bus and NTP protocol.
In the MSOFTX3000 OSTA2.0 platform, which boards does
the signal flow of KVM over IP pass through?
The signal flow of the KVM Over IP passes through the UPBs, SMMs, SWUs,
and OMU board.

The PDB working status is monitored by
the SMMs in the subrack located at the
bottom of a cabinet. For example, in an
integrated configuration cabinet, the PDB is
monitored by the SMMs in subrack 0, and
in a service processing cabinet, the PDB is
monitored by the SMMs in subrack 2.
During installation, one end of the PDB
cable is connected to the serial port
connectors in the monitoring panel at the
rear of the PDB and the other end is
connected to the COM2 serial ports in the
SDMs. Self data madule
