FAQ-possibility to connect other vendor to our OSN3500 on MSP protection

Publication Date:  2012-07-24 Views:  41 Downloads:  0
Issue Description
The customer need to connect other vendor with our equipment (OSN3500), but we need to ask about:
- Can the protection relies or no "msp 16 2fiber".
- What is about the trail, and can T2000 support!
Alarm Information
Null
Handling Process
If you want build the 1+1 MSP single ended switching protection with other vendor equipments in T2000, you can build a virtual NE or provisioning NE to replace the other vendor equipments. and you can see the status of Huawei equipment when occur a switch.
also for some problems can happen during interconnection such as timeslot numbering diffrence and overhead problems see attached document
Root Cause
Because the MSP ring and 1:1 MSP need use the K1,K2 byte to realize it, although it abide SDH protocol, but the implement details is different between different vendor equipments, so you can't have a MS_SP Ring or 1:1 MSP protection between two different vendor equipments.
The K1, K2 byte have no influence to 1+1 MSP single ended switching, so you can have a 1+1 MSP single ended switching (dual ended switch require APS) protection between two different vendor equipments.
Suggestions
we recommend to follow attached document when interconnection with other vendor
