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

• 2 BLSRs

Subtending rings from an ONS 15327 reduces the number of nodes and cards

required, and reduces external shelf-to-shelf cabling. Figure 29 shows an ONS

15327 with multiple subtending rings.
