A typical railway system has a three-level structure of
the Regional HQ, Divisions and stations/Sections
●
Regional HQ is responsible for planning, management
and Implementation of the railway unified
management, Delivery and Control system
●
Divisions have jurisdiction of their respective stations
and sections and their primary responsibilities are the
operations and maintenance of locomotives,
engineering/electrical services, rolling stock, power
supply for passenger transport and other auxiliary
duties.

●
It has a hierarchical aggregation architecture and it is recommended to build a ring network.
●
Medium and large sites and headquarter site make up the backbone network.
●
Access services at each small site are aggregated to the nearest medium and large sites and
access can be realized in a dual-node manner.
●
All branch sites and offices are connected as extended sites.

A wide bandwidth is required for
3G services.
Bandwidth requirement for service bearing: the bandwidth required for each site ranges from 50 to 200M
and is at least above 100M when video services are operated.
Networking of access network
●
As 100M services are connected for each site and
each access ring consists of 6 to 8 nodes, a
2.5/10G ring system is needed and planned service
bandwidth is above 500M
Networking of Aggregation network
●
10G devices are needed to connect all access rings.
●
Bandwidth utilization is related to the number of access
rings.

After reconstructing five major high-speed ring networks in 2001, China Railcom launched the optical cable communication
project for 6 major trunk lines in 2002 and “Baoji-Chengdu Line Access Network Project” was part of that project. For BaojiChengdu Line Access Network Project, 11 communication stations and 60 intermediate stations were arranged and the
project includes the “long-distance network ” and “access network”; wherein, within Xi’an-Chengdu Section the SDH STM-16
long-distance network, including 6 STM-16 ADMs and 6 REGs, was put into operation. ZTE adopted the MSTP technology
to build the long-distance network and this showed that it took into full consideration service scalability, smooth upgrade
ability, reliability and protective actions. At the same time, it constructed the STM-4 access network by using the ZXA10
access network device at each station to provide such services as automatic telephoning, 2/4-line audio channels,
N*64Kbit/s (V.35), 2B+D, etc, and at the same time it provided a 2Mb/s digital channel for the dedicated digital railway
Delivery system.

In this project, an E-MSTP system was newly provided for 8 stations to transmit video
information between such 8 stations. The system uses the RPR technology based on the
RPR over SDH, and thus has the advantages of statistical multiplexing, spatial reuse,
flexible bandwidth allocation, short transmission latency, etc.

For this project, the STM-16 optical synchronization digital transport devices are
arranged in signal cabins at the stations along the line and such devices are mainly
used for transporting Delivery services and monitoring services and also can provide
transmission channels for integrated information services.

For the backbone layer of the transmission network in this project, the STM-64 ADM
devices were adopted, and at stations and within sections at the access layer 224 sets of
622Mb/s MSTP devices and 20 sets of 155Mb/s MSTP devices in total were mounted.
The main services borne by such network are Delivery, integrated information and
monitoring services.

●
For frequency synchronization, transmission of synchronized
signals can be realized via the SDH network
●
The SDH network is used for telephone system for Delivery
services, and such service systems as GSM, WCDMA, etc.
2) Time
synchronization:

●
For accurate time synchronization, the transmission of clock signals cannot be realized via the MSTP network but can be only realized by installing the GPS
devices.
●
The installation of GPS devices can be used for the Delivery system and such civil systems requiring highly accurate clock signals as CDMA/CDMA2000, Wimax,
LTE, etc.
●
For applications having no high requirement for timing accuracy, clock signals can be transmitted via the network, such as the office system, ticketing system, etc.
