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?()
