Cisco ONS 15454 Product Overview, R3.3

Cisco ONS 15454 Product Overview
Network Configuration
Subtending Rings
UPSRs and BLSRs can be subtended from one another using one shared node; the
node can terminate and groom any one of the following ring combinations:
5 UPSRs, or
4 UPSRs and 1 BLSR, or
3 UPSRs and 2 BLSRs
Subtending rings from an ONS 15454 reduces the number of nodes and cards
required, and reduces external shelf-to-shelf cabling. Figure 24 shows an ONS
15454 with multiple subtending rings.
