NCS1K4-1.2T-L-K9 Line Card Support

The NCS 1014 chassis now supports the NCS1K4-1.2T-L-K9 line card. This card is the licensed version of the NCS 1004 1.2T line card and offers a "pay as you grow" model. This card provides 4x 100G of unencrypted client capacity on day one. The licensed version of the card allows you to

• purchase 100G incremental licenses to expand up to 12x 100G capacity for each card.

• set line rates from 100 to 600G.

• deploy long haul and subsea licenses in NCS 1014.

System Setup and Software Installation

Automated File Management System

The new Automated File Management System is designed for efficient file handling on the NCS 1014 node. This system automatically archives older files and removes them from local nodes to free up valuable SSD space. It manages the following types of files:

• System-generated log files

• Showtech-related residual files

Configuration

Last Link Flap Detection for Transponder Controllers

This feature introduces the detection of the last link flap for various transponder controllers. It provides the elapsed time since the occurrence of the last flap for each controller in the show controllers output. Link flap refers to the state transition of controllers from UP state to another state or from other states to UP state. This information enables network administrators to effectively monitor and troubleshoot signal stability and performance across the network

Parameter added:

• Last Link Flap value

Loopback enhancements

The internal and line loopback configurations on the Ethernet controller have been enhanced to activate a loop-and-drop mechanism. This mechanism prevents traffic from flowing in the opposite direction of the loopback. This feature is supported on these cards: NCS1K14-2.4T-K9, NCS1K14-2.4T-X-K9, and NCS1K4-QXP-K9. For the NCS1K4-1.2T-K9, only internal loop-and-drop is supported.

In internal loopback, this is achieved by shutting down the transmit power at the client Ethernet controller. In line loopback, a local fault alarm signal is inserted toward the trunk.

This enhancement is particularly useful when using the PRBS pattern, as it prevents unnecessary PRBS traffic from causing unwanted events and alarms at the router ports.

New PRBS Counters on Ethernet Controllers

The new Pseudo-Random Binary Sequence (PRBS) counters on Ethernet controllers collects statistics in a cumulative manner.

The output of the show controllers controller-type R/S/I/P command now includes these counters:

• Configured Time

• First Lock Established Time.

• Lock Time (in seconds)

• Bit Errors

• Lock Found Count

• Lock the Lost Count

• Result

Performance Monitoring Enhancements

You can now view historical Performance Monitoring (PM) parameters for the past 1 to 7 days for the 24-hour interval on these controllers:

• CoherentDSP

• Ethernet

• ODU-layer

This feature enhances data collection directly from the equipment, providing a comprehensive view of performance over time.

Parameter added:

• bucket value

Data Models

gNOI for BERT

Extensible Manageability Services (EMS) gNOI supports Bit Error Rate Testing (BERT) operations on NCS 1014 for the following remote procedure calls (RPCs):

• StartBERT

• StopBERT

• GetBERTResults

gNOI for BERT is a vendor agnostic open configuration method of enabling and testing network links through the Pseudo Random Binary Sequence (PRBS) feature.
