Hi there!
This time, I will share with you a cascading problem for a VC-4C service.
The following figure shows the route diagram of the trail. A VC-4C concatenation service is configured between NE A and NE G, and the VC-4C service is accessed at both ends. However, because the trunk circuit is purchased from station E to station G, the third-party SDH is purchased. The third-party SDH is not cascaded, if other sites are cascaded services, can the cascading service work normally? In other words, the two ends are cascaded services. The intermediate stations are not cascaded. Can the circuit work normally?
In fact, if the intermediate third-party SDH is not the configured concatenation service, the service is unavailable. Some special packets cannot be forwarded effectively, and the entire service path must be configured in the same way.
That's all, I welcome everyone to leave a message and exchange in the comment area!
Thank you！
