12.11 OC-N Speed Upgrades
A span is the optical fiber connection between two ONS 15454 nodes. In a span (optical speed) 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:
•
Single-port OC-12 to OC-48
•
Single-port OC-12 to OC-192
•
Single-port OC-12 to four-port OC-12
•
Single-port OC-12 to MRC-12
•
Four-port OC-12 to MRC-2.5G-4
•
OC-48 to OC-192
•
MRC-12 to OC-192 or OC192-XFP
•
MRC-2.5G-4 to OC-192 or OC192-XFP
•
OC-48 to OC192SR1/STM64IO Short Reach or OC192/STM64 Any Reach
Note
Only Software Release 8.5.3 or higher supports span upgrades on MRC-12 and MRC-2.5G-4
cards to OC-192 or OC192-XFP. To perform this span upgrade the card’s SFP must be in PPM
Slot 1 only.
You can also perform in-service card upgrades for the following ONS 15454 cards:
•
Four-port OC-3 to eight-port OC-3
