Dlp- D196 Delete An Ms-Spring From A Single Node - Cisco ONS 15454 SDH Procedure Manual

Chapter 18 DLPs D100 to D199
Observe the Timing Mode field to see the type of timing (Line, External, Mixed) that has been set for
Step 2
that node.
Step 3 Scroll down to the Reference List and observe the NE Reference fields to see the timing references
provisioned for that node.
Step 4 If the removed node was the only building integrated timing supply (BITS) timing source, perform the
following:
a.
b.
c.
If the removed node was not the only BITS timing source, provision the adjacent nodes to line timing
Step 5
using SDH links (east and west) as timing sources, traceable to the node with external BITS timing. See
the
Return to your originating procedure (NTP).

Contact your synchronization coordinator or appropriate personnel before continuing with this
procedure.
Look for another node on the ring that can be used as a BITS source and set that node's Timing Mode
to External. Choose that node as the primary timing source for all other nodes in the ring. See the
"DLP-D157 Change the Node Timing Source" task on page
If no node in the reduced ring can be used as a BITS source, choose one node to be your internal
timing source. Set that node's Timing Mode to External, set the BITS-1 and BITS-2 BITS In State
to OOS, and set the NE Reference to Internal. Then, choose line timing for all other nodes in the
ring. This forces the first node to be their primary timing source. (See the
Node Timing Source" task on page
This type of timing conforms to SETS requirements and is not considered optimal.

This task deletes an MS-SPRing from a node after you remove the node
from an MS-SPRing.

If the node that was removed is connected to the same LAN as your computer, from the File menu,
choose Add Node, then enter the node name or IP address.
If the node that was removed is not connected to the same LAN as your computer, you must connect
to the node using a direct connection. See
procedures.
