| Onsite/Remote | Onsite or remote |
| Security Level | Provisioning or higher |
| |
Step 1 | From the View menu, choose Go to Network View. |
Step 2 | Click the Provisioning > MS-SPRing tabs. |
Step 3 | Click Create MS-SPRing. | |
Step 4 | In the MS-SPRing Creation dialog box, set the MS-SPRing properties: |
•Ring Type—Choose two-fiber.
•Speed—Choose the MS-SPRing ring speed: STM-4, STM-16, or STM-64. The speed must match the STM-N speed of the MS-SPRing trunk (span) ports.
•Ring Name—Assign a ring name. The name can be from 1 to 6 characters in length. Any alphanumeric string is permissible, and uppercase and lowercase letters can be combined. Do not use the character string All in either uppercase or lowercase letters; this is a TL1 keyword and will be rejected. Do not choose a name that is already assigned to another MS-SPRing.
•Reversion time—Set the amount of time that will pass before the traffic reverts to the original working path following a ring switch. The default is 5 minutes. Ring reversion can be set to Never.
Step 5 Click Next. If the network graphic appears, go to Step 6.
If CTC determines that an MS-SPRing cannot be created, for example, not enough optical cards are installed or it finds circuits with SNCP selectors, a “Cannot Create MS-SPRing” message appears. If this occurs, complete the following steps:
a.Click OK.
b.In the Create MS-SPRing window, click Excluded Nodes. Review the information explaining why the MS-SPRing could not be created, then click OK.
c.Depending on the problem, click Back to start over or click Cancel to cancel the operation.
d.Complete the NTP-F147 Provision MS-SPRing Nodes, page 5-6, making sure all steps are completed accurately, then start this procedure again.
Step 6 In the network graphic, double-click an MS-SPRing span line. If the span line is DCC-connected to other MS-SPRing ports that constitute a complete ring, the lines turn blue. If the lines do not form a complete ring, double-click the span lines until a complete ring is formed. When the ring is DCC-connected, go to Step 7.
Step 7 Click Finish. If the MS-SPRing window appears with the MS-SPRing you created, go to Step 8. If a “Cannot Create MS-SPRing” or “Error While Creating MS-SPRing” message appears:
a.Click OK.
b.In the Create MS-SPRing window, click Excluded Nodes. Review the information explaining why the MS-SPRing could not be created, then click OK.
c.Depending on the problem, click Back to start over or click Cancel to cancel the operation.
d.Complete the NTP-F147 Provision MS-SPRing Nodes, page 5-6, making sure all steps are completed accurately, then start this procedure again.
Note Some or all of the following alarms might briefly appear during MS-SPRing setup: E-W-MISMATCH, RING-MISMATCH, APSCIMP, APSCDFLTK, and MSSP-OOSYNC.
