MS-SPRing (Node View)
Use the node view MS-SPRing tab to view node MS-SPRing information including the ring name, ring type (two-fiber or four-fiber), status, the node’s MS-SPRing ID, any active ring or span reversions, and the node’s east and west spans. You can also create, delete, and edit the MS-SPRing, view the MS-SPRing map, and convert two-fiber MS-SPRings to four-fiber MS-SPRings.
 
Item
Description
Type
The MS-SPRing type, either two-fiber or four-fiber.
Rate
The MS-SPRing STM-N rate.
Ring Name
The user-assigned MS-SPRing name.
Node ID
The node’s MS-SPRing identification number.
Ring Reversion
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 reversions can be set to Never.
Span Reversion
Set the amount of time that will pass before the traffic reverts to the original working path following a span switch. The default is 5 minutes. Span reversions can be set to Never.
West Line
Displays the slot and card used for the MS-SPRing west line.
East Line
Displays the slot and card used for the MS-SPRing east line.
Create
Displays the MS-SPRing Creation wizard, where you can create a new MS-SPRing.
Delete
Deletes the highlighted MS-SPRing.
Ring Map
Displays the MS-SPRing map.
Squelch Table
Displays the MS-SPRing squelch table. The table shows VC4s or VC3s that will be squelched for every isolated node. The VC4s or VC3s are replaced by the appropriate path alarm indication signal (AIS) to prevent misconnections. MS-SPRing squelching is performed on VC4s that carry VC4 circuits only or on VC3s that carry VC3 circuits only.
Rip Table
Displays the ring interworking on protection (RIP) table for an MS-SPRing. The secondary node maintains a RIP table that contains, for each incoming and outgoing inter-ring circuit carried on the protection bandwidth, the source or terminating node address and the primary node address.
Upgrade
If the highlighted MS-SPRing is two-fiber, the button allows you to upgrade the MS-SPRing to a four-fiber MS-SPRing.
Apply
Applies changes made to the MS-SPRing fields.
Reset
Cancels any MS-SPRing subtab changes and returns the fields to their last-saved settings.
Help
Displays context-sensitive help.
