Why is an STM-1 2F-MS-SPRing NOT feasible?()
A.
An equal amount of working and protect bandwidth is required.
B.
DCC bandwidth is not large enough to handle K1/K2 processing.
C.
Switch times would exceed 50 ms for an STM-1 MS-SPRing ring.
D.
There is not enough bandwidth in an STM-1 ring to justify MS-SPRing protection.
