A. In an MS-SPRing， all paths are protected.
B. MS-SPRing is always a high-order protection.
C. A low order circuit cannot be protected by an MS-SPRing.
D. There is no theoretical limit in the number of nodes in an SNCP ring.
In order to avoid misconnections due to a failed node in an MS-SPRing， Alarm Indication Signals （AISs） are sent on every channel normally terminating in that node.
What is the name of this process？（）

B. switching
C. squelching
D. nodal bypass

A. SNCP traffic is switched from the first node that recieves the AIS. MS-SPRing traffic is rerouted from the first in the ring.
B. SNCP traffic is selected at the destination node in the ring. MS-SPRing is rerouted from the originating node in the ring.
C. SNCP traffic is rerouted from the originating node in the ring. MS-SPRing traffic is rerouted from the originating node in the ring.
D. SNCP traffic is selected at the destination node in the ring. MS-SPRing traffic is rerouted from the last reachable node in the ring.
