11.2.4 MS-SPRing Application Sample
Figure 11-8 shows a sample two-fiber MS-SPRing implementation with five nodes. A regional
long-distance network connects to other carriers at Node 0. Traffic is delivered to the service provider’s
major hubs.
• Carrier 1 delivers six E-3s over two STM-1 spans to Node 0. Carrier 2 provides twelve E-3s directly.
Node 0 receives the signals and delivers them around the ring to the appropriate node.
• The ring also brings 14 E-1s back from each remote site to Node 0. Intermediate nodes serve these
shorter regional connections.
• The ONS 15454 SDH STM-1 card supports a total of four STM-1 ports so that two additional STM-1
spans can be added at little cost.
