17.3.1 Automatic Node Setup Parameters
• 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.
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:
• 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.
17.3.1 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. Table 17-2 shows ANS parameters arranged in east and
west, transmit and receive groups.
