suggestion to my company
bull Huawei is one of the famous in wireless BSC transmission optics core network and software application in most part of the word so in Iran Huawei has many contract especially in region 2amp4 and Huawei productrsquos have been used in BTS BSS optics and recently in core network so I have divided all of the network project in 5 partrsquos and all this part need to be done carefully with high quality
bull 1fundation civil construction and towerbull 2power and generatorbull 3BTS installation and MW(E1 transmission) and TIC bull 4BSC and all the related equipment bull 5transmission equipment (SDH fiber optic ODF)
Page 15
HUAWEI TECHNOLOGIES CO LTD Page 16
So In transmission network we can make more closely friendship between project and TI group and give sub-Cons more power supervision and good management so this can help us to be owner for a organized and satisfied network and this case improve the quality of the work and make all maintenance part easy and simple and can appreciate us from customer side
please consider a few pictures so all of those pictures belong to all the network in different part and all of us are responsible and need to work hard for Huawei our company
HUAWEI TECHNOLOGIES CO LTD Page 17
I hope more for future and try to learn more in transmission and improve
myself to be one of the useful and best engineer in Huawei company
and wish to continue hellip
And need to thanks all the MSD members especially MSD department manager
At last I need to thank Mr WUDONGCHUAN cause of the best teaching and
good support
MSD department Rasoul nadi Region2 transmission engineer thanks all

MSP protection
bull The maximum service capacity with protection available is KxSTM-N2 (K the number of
bull nodes on the ring)
bull In the case of the evenly distributed services between nodes the transmission capacity can be
bull greatly increased While for the centralized services this kind of ring has no obvious
bull advantages
bull In the case of the STM-4 two-fiber bidirectional shared MSP ring the first and second VC-4s
bull are working channels and the third and forth VC-4s are protection channels
bull In the case of a two-fiber bidirectional Shared MSP ring the first to the eighth VC-4 channels
bull are working channels and the ninth to the sixteenth channels are protection channels
bull Respective four bits of K1 and K2 bytes are used to represent node ID so the number of
bull nodes on this ring is 16 at most Note that a relay station does not occupy any node number
bull If no extra traffic is borne no request for bridge is made earlier and the fiber is shorter than
bull 1200km the switching completion time shall be less than 50ms

Checking Data Configuration of the Faulty Station
bull When checking the data configuration of the faulty station the network wide data should be
bull also taken into consideration Specifically for the SNCP switching services
bull 1048698 First check if the triggering conditions are correctly configured and if the alarms
bull triggering SNCP switching have been received
bull 1048698 Second check if the protection attributes are correctly configured at the intersection
bull station
bull 1048698 Third check if the protection attributes are correctly configured at the sourcesink
bull stations according to respective network structures
bull 1048698 Finally check if the pass-through is configured at related intermediate stations

MSP protection
bull The maximum service capacity with protection available is KxSTM-N2 (K the number of
bull nodes on the ring)
bull In the case of the evenly distributed services between nodes the transmission capacity can be
bull greatly increased While for the centralized services this kind of ring has no obvious
bull advantages
bull In the case of the STM-4 two-fiber bidirectional shared MSP ring the first and second VC-4s
bull are working channels and the third and forth VC-4s are protection channels
bull In the case of a two-fiber bidirectional Shared MSP ring the first to the eighth VC-4 channels
bull are working channels and the ninth to the sixteenth channels are protection channels
bull Respective four bits of K1 and K2 bytes are used to represent node ID so the number of
bull nodes on this ring is 16 at most Note that a relay station does not occupy any node number
bull If no extra traffic is borne no request for bridge is made earlier and the fiber is shorter than
bull 1200km the switching completion time shall be less than 50ms

suggestion to my company
bull Huawei is one of the famous in wireless BSC transmission optics core network and software application in most part of the word so in Iran Huawei has many contract especially in region 2amp4 and Huawei productrsquos have been used in BTS BSS optics and recently in core network so I have divided all of the network project in 5 partrsquos and all this part need to be done carefully with high quality
bull 1fundation civil construction and towerbull 2power and generatorbull 3BTS installation and MW(E1 transmission) and TIC bull 4BSC and all the related equipment bull 5transmission equipment (SDH fiber optic ODF)

So In transmission network we can make more closely friendship between project and TI group and give sub-Cons more power supervision and good management so this can help us to be owner for a organized and satisfied network and this case improve the quality of the work and make all maintenance part easy and simple and can appreciate us from customer side
please consider a few pictures so all of those pictures belong to all the network in different part and all of us are responsible and need to work hard for Huawei our company

I hope more for future and try to learn more in transmission and improve
myself to be one of the useful and best engineer in Huawei company
and wish to continue hellip
And need to thanks all the MSD members especially MSD department manager
At last I need to thank Mr WUDONGCHUAN cause of the best teaching and
good support
MSD department Rasoul nadi Region2 transmission engineer thanks all

MSP protection
bull The maximum service capacity with protection available is KxSTM-N2 (K the number of
bull nodes on the ring)
bull In the case of the evenly distributed services between nodes the transmission capacity can be
bull greatly increased While for the centralized services this kind of ring has no obvious
bull advantages
bull In the case of the STM-4 two-fiber bidirectional shared MSP ring the first and second VC-4s
bull are working channels and the third and forth VC-4s are protection channels
bull In the case of a two-fiber bidirectional Shared MSP ring the first to the eighth VC-4 channels
bull are working channels and the ninth to the sixteenth channels are protection channels
bull Respective four bits of K1 and K2 bytes are used to represent node ID so the number of
bull nodes on this ring is 16 at most Note that a relay station does not occupy any node number
bull If no extra traffic is borne no request for bridge is made earlier and the fiber is shorter than
bull 1200km the switching completion time shall be less than 50ms

Checking Data Configuration of the Faulty Station
bull When checking the data configuration of the faulty station the network wide data should be
bull also taken into consideration Specifically for the SNCP switching services
bull 1048698 First check if the triggering conditions are correctly configured and if the alarms
bull triggering SNCP switching have been received
bull 1048698 Second check if the protection attributes are correctly configured at the intersection
bull station
bull 1048698 Third check if the protection attributes are correctly configured at the sourcesink
bull stations according to respective network structures
bull 1048698 Finally check if the pass-through is configured at related intermediate stations
