Table 16: Sc-Aps Versus Mc-Aps Protection - Alcatel-Lucent 7750 Configuration Manual

Single Chassis and Multi-Chassis APS
APS can operate in a single chassis configuration (SC-APS) or in a multi-chassis configuration
(MC-APS).
An SC-APS group can span multiple ports, MDAs or IOMs within a single node whereas as MC-
APS can span two separate nodes.
