Chapter 11 SDH Topologies and Upgrades
11.9.1 Span Upgrade Wizard
11.9.1 Span Upgrade Wizard
The Span Upgrade Wizard automates all steps in the manual span upgrade procedure (MS-SPRing,
SNCP ring, and 1+1). The wizard can upgrade both lines on one side of a four-fiber MS-SPRing or both
lines of a 1+1 group; the wizard upgrades SNCP rings and two-fiber MS-SPRings one line at a time. The
Span Upgrade Wizard requires that spans have DCCs enabled.
The Span Upgrade Wizard provides no way to back out of an upgrade. In the case of an error, you must
exit the wizard and initiate the manual procedure to either continue with the upgrade or back out of it.
To continue with the manual procedure, examine the standing conditions and alarms to identify the stage
in which the wizard failure occurred.
11.9.2 Manual Span Upgrades
Manual Span Upgrades are mainly provided as error recovery for the Span Upgrade Wizard, but they can
be used to perform span upgrades. Downgrading can be performed to back out of a span upgrade. The
procedure for downgrading is the same as upgrading except that you choose a lower-rate card type. You
cannot downgrade if circuits exist on the VCs that will be removed (the higher VCs).
Procedures for manual span upgrades can be found in the “Upgrade Cards and Spans” chapter in the
Cisco ONS 15454 SDH Procedure Guide. Five manual span upgrade options are available:
• Upgrade on a two-fiber MS-SPRing
• Upgrade on a four-fiber MS-SPRing
• Upgrade on an SNCP ring
• Upgrade on a 1+1 protection group
• Upgrade on an unprotected span
