In an SC-APS group, both the working and protection circuits terminate on the same node. SC-APS is supported in unidirectional or bidirectional mode on:
2-port OC3/STM1 Channelized Adapter cards for TDM CES (Cpipes) and TDM CESoETH with MEF 8 with DS3/DS1/E1/DS0 channels
4-port OC3/STM1 / 1-port OC12/STM4 Adapter cards for MLPPP access ports or TDM CES (Cpipes) and TDM CESoETH (MEFÂ 8) access ports with DS1/E1 channels, or on a network port configured for POS
4-port OC3/STM1 Clear Channel Adapter cards network side (configured for POS operation)
SC-APS with TDM access is supported on DS3, DS1, E1, and DS0 (64 kb/s) channels.
The working and protection circuits of an SC-APS group must be on two ports on different adapter cards.
Figure: SC-APS with Physical Port and Adapter Card Protection shows an SC-APS group with physical port and adapter card failure protection. Figure: SC-APS Application shows a packet network using SC-APS.
