Introduction
The 1643 AM / 1643 AMS provide various protective switching mechanisms where
necessary to support a high level of service availability.
Reliability and service availability
Protection mechanisms are supported by the 1643 AM / 1643 AMS:
• path protection or SNC/N protection (SubNetwork Connection protection with
Non-intrusive monitoring) for higher and lower order VCs
• 1+1 multiplex section protection (MSP) for STM-1 optical interfaces
Ethernet traffic can be protected by:
• spanning tree protocol
• link capacity adjustment scheme (LCAS)
