SDH ASON Signaling Maintenance

Using this function, you can perform ASON signaling maintenance operations.

Navigation Path

In the NE Explorer, click the NE and select ASON > Advanced Maintenance from the Function Tree. Click SDH ASON Signaling Maintenance tab.

NOTE:

The ASON signaling maintenance operations are not recorded in the operation log.

Parameters

Field	Value	Description
Query ASON Trail	With this node as source. With this node as the intermediate node. With this node as sink. Passing through this node. Default: Passing through this node.	Under Query ASON Trail, you can select a query mode for ASON signaling maintenance.
Name	Source NE-Sink NE-ASON-Trail-000x For example: NE1-NE3-ASON-Trail-0001	Displays the name of the ASON trail.
Source (Sink) NE	For example, NE11	Displays the name of the source or sink NE.
Source (Sink) Node	For example, 1.1.1.11	Displays the source or sink node ID.
Type	ASON Trail, ASON Server Trail, Differentially Protected ASON Trail, Differentially Protected ASON Server Trail	Displays the type of an ASON trail.
Class	Diamond, Gold, Silver, Copper, Iron	Displays the protection type of the ASON trail. There are five types of ASON trails: diamond, gold, silver, copper and iron. There are three types of ASON server trails: diamond, gold, silver and copper. A diamond service is a service provided with 1+1 protection from its source node to its sink node. It is also called 1+1 service. A gold service is also called a 1:1 service. When a fiber on the path of a gold service is cut, the ASON provides MSP for the service at first. If MSP fails, the ASON reroutes the gold service. A silver service is also called a rerouting service. When an ASON trail is interrupted, periodic rerouting is performed until the rerouting succeeds. During this process, if the original route is recovered, rerouting stops. A copper service is also called an unprotected service. If its trail fails, service is interrupted and there is no rerouting. An iron service can be preempted by a higher class service. For example, the extra service is created by using the protection MSP link of a gold service.
Direction	Bidirectional	Bidirectional means both the source and the sink can transmit and receive services. Unidirectional means the source transmits services and the sink receives services. At present, the ASON supports bidirectional only.
Active/Standby Status	Primary, Secondary	Displays the active/standby status of the service on the trail.
Created On	For example, 05/09/2008 11:18:15	Displays the time when the ASON trail was created.
Revertive Mode	Non-Revertive, Automatically Revertive, Scheduled Revertive	Displays the revertive attribute of a trail during rerouting. It indicates whether a trail can automatically revert to the original route that has been restored after service rerouting.
Trail Index	For example: 31, 326	Displays the trail index.
Instance	For example: 118, 152	Displays the trail instance.
Node Location	Source Node, Intermediate Node, Sink Node	Displays the node location.
Service Status	up, down	Displays the service status.
Operation Sign	For example, Normal	Displays the operation sign.
Setting	See the following sample value. The selected column's width: 75 Pixels The selected column's name: Source	Allows the user to set trail list fields. The user can specify what fields to display and in what order the fields are displayed. The user can also set the width for a selected column.
