Calculation method of the SDH lower-order cross-connect capacity
Calculation method of the SDH lower-order cross-connect capacity: For example, if the queried VC-12 quantity of lower-order cross-connections is 2016, how do I calculate the lower-order cross-connect capacity? First, convert the VC-12 quantity to the VC-4 quantity. As one VC-4 contains 63 VC-12s, the VC-4 quantity is 32 (2016/63). Second, calculate the capacity. As the capacity of 64 VC-4s is 10 Gbit/s, the capacity of 32 VC-4s is 5 Gbit/s.

Relationship of SDH VC-4, VC-3, and VC-12
Relationship of SDH VC-4, VC-3, and VC-12: One VC-4 contains three VC-3s and 63 VC-12s.

Bandwidth of VC-3
Bandwidth of VC-3: 9 columns x 85 rows x 8000 frame/s x 8 bits = 48960000 bit/s (namely, 48.96 Mbit/s).

Whether higher-order bit errors can be detected when VC-4 does not carry services
Whether higher-order bit errors can be detected when VC-4 does not carry services: Higher-order bit errors cannot be detected when VC-4 does not carry services. They can be detected when VC-4 carries services.
