Figure 26-4 Aps 1+1 Redundancy, Installing Aps Backcards In Aps Redundant Backplane - Cisco BPX-BXM-155-8DX Installation And Configuration Manual

APS 1+1 (Card and Line Redundancy)
• BPX-RDNT-SM-622-2 (2 port, medium reach, SMF, FC connector)
Each of the listed model numbers includes two single backcards and one mini-backplane (providing
cross coupling of two backcards).
The single backcards and mini-backplane can be ordered as spares. Their model numbers are:
BPX-RDNT-BP= (common backplane for all redundant APS backcards)
•
BPX-LR-155-8R-BC= (for BPX-RDNT-LR-155-8)
•
BPX-LR-622-2R-BC= (for BPX-RDNT-LR-622-2)
•
BPX-SMF-155-4R-BC= (for BPX-RDNT-SM-155-4)
•
BPX-SMF-155-8R-BC= (for BPX-RDNT-SM-155-8)
•
• BPX-SMF-622-R-BC= (for BPX-RDNT-SM-622)
• BPX-SMF-622-2R-BC= (for BPX-RDNT-SM-622-2)

Traffic protected by APS 1+1 redundancy is carried via the working line and the protection line
simultaneously (see Figure 26-5). Bridging is implemented such that the same payloads are transmitted
identically over the working line as the protection line.
