Automatic Node Setup Parameters - Cisco ONS 15454 DWDM Installation And Operation Manual

Chapter 15 DWDM Node Reference
ANS assumes that every DWDM port has a line direction parameter that is either west to east (W-E) or
east to west (E-W). ANS automatically configures the mandatory optical connections according to
following main rules:
•
•
•
•
•
•
Optical patch cords are passive devices that are not autodiscovered by ANS. However, optical patch
cords are used to build the alarm correlation graph. From CTC or TL1 you can:
•
•
•
•
•
After you launch ANS, the following status are provided for each ANS parameter:
•
•
•
•
•
Optical connections are identified by the two termination points, each with an assigned slot and port.
ANS checks that a new connection is feasible (according to embedded connection rules) and returns a
denied message in the case of a violation.
ANS requires provisioning of the expected wavelength. When provisioning the expected wavelength, the
following rules apply:
•

15.5.1 Automatic Node Setup Parameters

All ONS 15454 ANS parameters are calculated by Cisco MetroPlanner for nodes configured for metro
core networks. (Parameters must be configured manually for metro access nodes.) Cisco MetroPlanner
exports the calculated parameters to an ASCII file called "NE Update." In CTC, you can import the NE
Update file to automatically provision the node.
west, transmit and receive groups.
September 2004
Cards equipped in Slots 1 to 6 have a drop section facing west.
Cards equipped in Slots 12 to 17 have a drop section facing east.
Contiguous cards are cascaded on the express path.
4MD-xx.x and AD-xB-xx.x are always optically coupled.
A 4MD-xx.x absence forces an optical pass-through connection.
Transmit (Tx) ports are always connected to receive (Rx) ports.
Calculate the default connections on the NE.
Retrieve the list of existing connections.
Retrieve the list of free ports.
Create new connections or modify existing ones.
Launch ANS.
Success - Changed—The parameter setpoint was recalculated successfully.
Success - Unchanged—The parameter setpoint did not need recalculation.
Not Applicable—The parameter setpoint does not apply to this node type.
Fail - Out of Range—The calculated setpoint is outside the expected range.
Fail - Port in IS State—The parameter could not be calculated because the port is in-service.
The card name is generically characterized by the card family, and not the particular wavelengths
supported (for example, AD-2C for all 2-channel OADMs).
At the provisioning layer, you can provision a generic card for a specific slot using CTC or TL1.
Wavelength assignment is done at the port level.
An equipment mismatch alarm is raised when a mismatch between the identified and provisioned
value occurs. The default value for the provisioned attribute is AUTO.
