Customer wants to create Ethernet ( 1VC3 bounded) and none protected service between
117-Queen Nour (Metro1000) - S1-EGS and 705-3G BeitRas- S2-EGS4
Service creation procedure as below:
1- create NP_Chain (None protected chain) on new VC4 (VC4#5)
2-create SDH service using trail (VC4 Server trail using VC4#5) then create VC3 service (117-S1-VC4:1,VC3:1) to (705-S2-VC4:1,VC3:1).
3-bound path the above VC3 to the EGS VCTRUNK:1 & EGS4 VCTRUNK1.
4- create EPLAN service and add port1 & VCTRUNK1 at both Metro-EGS & OSN-EGS4.
once they finish the service configuration the Ethernet service never work, always down.
and the SDH service trail (VC3) has alarm (TU_AIS) alarm.
Ethernet Service down.
TU_AIS_VC3 reported at both OSN7500 & Metro1000
1. The actual fiber connection on site must match the actual data on NMS, so its better to use Fiber search rather than creating fiber manually.
2.the SDH trails & protection follow the NMS data so if any mismatch or wrong data on NMS will be reflected on the service creation and service route.
3.High engineering quality and good installation & labeling may save alot of efforts and smooth the maintinance job.
