● 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.

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● 10G devices are needed to connect all access rings.

● Bandwidth utilization is related to the number of access rings.

As 5 to 10 cameras are needed for each small station and we take an average number, say 8; the resolution is SD and the video conference system also needs to be taken into account, so the bandwidth required is 6*8+8=56M.

As 10 to 15 cameras are needed for each big station and we take an average number, say 12; the resolution is SD and the video conference system also needs to be taken into account, so the bandwidth required is 6*12+8=80M.The total bandwidth required is:Number of big stations*80M+number of small stations*56M

● The bandwidth required for the access layer ranges from 200 to 400M (4 to 8 nodes).

● The bandwidth required for the backbone layer ranges from 1 to 3G (4 to 8 access rings).

● If HD video surveillance is needed, the planned bandwidth should be doubled.

● Video conferencing services can be connected to the MSTP/ in EoS mode or PTN

● Separate networking is recommended for monitoring services, which should be directly connected to the MSTP in the EOS mode or PTN

Baoji Fengzhou Huixian Lueyang Yangpingguan Guangyuan Banzhuyuan Jiangyou Mianyang Deyang

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 Baoji-Chengdu 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.

Suggestions for solution for synchronous network deployment

… …

1) Frequency synchronization:

StationStation

2) Time synchronization:

StationStation

PRCPRC/SSU ActiveStandby

GPS GPS GPS

● 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.

● 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.
