In-Service Span Upgrades
A span is the optical-fiber connection between two ONS 15454 nodes. In a span
upgrade, the transmission rate of a span is upgraded from a lower to a higher
OC-N signal but all other span configuration attributes remain unchanged. With
multiple nodes, a span upgrade is a coordinated series of upgrades on all nodes in
the ring or protection group. You can perform in-service span upgrades for the
following ONS 15454 cards:
• OC-12 to OC-48
• OC-12 to OC-192
• OC-48 to OC-192
