Step 10
To recreate the circuits, see
Chapter 6, “Create Circuits and Low-Order Tunnels.”
and choose the
applicable procedure for the circuit type you want to enter.
Note
To add additional nodes to an MS-SPRing, see the
“NTP-D353 Add an MS-SPRing Node”
.
Stop. You have completed this procedure.
NTP-D211 Convert a Two-Fiber MS-SPRing to a Four-Fiber
MS-SPRing Automatically
Note
Two-fiber STM-16 or STM-64 MS-SPRings can be converted to four-fiber MS-SPRings. To convert, you
install two additional STM-16 or STM-64 cards at each two-fiber MS-SPRing node, then log into CTC
and convert the MS-SPRing from two-fiber to four-fiber. The fibers that were divided into working and
protect bandwidths for the two-fiber MS-SPRing are now fully allocated for working MS-SPRing traffic.
A span upgrade can be performed prior to the two-fiber to four-fiber MS-SPRing conversion.
Note
MS-SPRing protection channel access (PCA) circuits, if present, will remain in their existing VC4s.
Therefore, they will be located on the working path of the four-fiber MS-SPRing and will have full
MS-SPRing protection. To route PCA circuits on protection channels in the four-fiber MS-SPRing,
delete and recreate the circuits after the upgrade. For example, if you upgrade a two-fiber STM-16
MS-SPRing to four-fiber, PCA circuits on the protection VC4s (VCs 8 to 16) in the two-fiber
MS-SPRing will remain in their existing VC4s, which are working VC4s in the four-fiber MS-SPRing.
Deleting and recreating the STM-16 PCA circuits moves the circuits to VC4s 1 to 7 in the protect
bandwidth of the four-fiber MS-SPRing. To delete circuits, see the
Overhead Circuits and Server Trails” procedure on page 7-4
. To create circuits, see
Circuits and Low-Order Tunnels.”
Note
Before beginning this procedure, optical transmit and receive levels should be in their acceptable range
as shown in
.
Purpose
This procedure upgrades a two-fiber MS-SPRing to a four-fiber
MS-SPRing without disrupting traffic. The conversion will be easier if
the same east and west configuration is used on all nodes being
upgraded.
