Cisco NCS 1010 Datapath Configuration Guide, IOS XR Releases 7.11.x, 24.2.x, and 24.3.x

Table 1. Controllers
Controller Types	Description
Optical Transport Section (OTS)	The OTS controller holds all the optical parameters for the OTS optical interfaces.
OTS-OCH	The OTS-OCH controller is created on the LINE side of the OLT and ILA nodes using the `hw-module` command in Flex-Grid configuration. OTS-OCH controller supports optical cross-connection between the LINE side and ADD/DROP side of the OLT nodes only. The channel IDs must be the same for both LINE side and COM side OTS-OCH controllers.
Optical Service Channel (OSC)	The OSC controller represents the optical layer of the OSC channel. Line ports host the OSC controller.
Distributed Feedback (DFB)	The DFB controller represents the dedicated DFB laser on the line side of the OLT and ILA nodes with a RAMAN module for link continuity. The line ports host the DFB controller along with the OSC controller.
Optical Channel (OCH)	By default, the OCH controllers are automatically configured when Mux/Demux panels and breakout panels are brought up.
Optical Multiplex Section (OMS)	By default, the OMS controllers are automatically configured when Mux/Demux panels and breakout panels are brought up.

OTS Controllers

There are two types of controller models supported on Cisco NCS 1010. They are:

ILA Controller Model

When the NCS1K-ILA-2R-C, NCS1K-ILA-L, NCS1K-E-ILA-R-C, NCS1K-E-ILA-2R-C, NCS1K-E-ILA-R-C-2, NCS1K-ILA-R-C and NCS1K-ILA-C cards are brought up, four OTS controllers are created by default. The OTS controllers are:

OTS controllers for side 1:
- LINE 0 port: ots 0/0/0/0 (L band line OTS controller)
- L-BAND 1 port: ots 0/0/0/1 (L band line OTS controller)
OTS controllers for side 2:
- LINE 2 port: ots 0/0/0/2 (L band line OTS controller)
- L-BAND 3 port: ots 0/0/0/3 (L band line OTS controller)

Table 2. Feature History
Feature Name	Release Information	Feature Description
NCS 1010 L-Band and C+L-Band Support.	Cisco IOS XR Release 7.9.1	NCS 1010 now supports C+L-Band. The addition of the L-Band to the existing C-Band provides more channels increasing the data transfer capacity of the optical line system.

L-band gain range: (ILA)
- EDFA Gain Range 1 range: 10.8 — 25.8
- EDFA Gain Range 2 range: 18.8 — 38.8
EDFA1: Instance 1 (OLT )
- 0 -> Gain Range Mode 1: 13.3dB — 26.3dB
- 1 -> Gain Range mode 2: 21.3dB — 39.3dB

The following figures and tables show the three ILA variants and the mapping between physical ports and controllers:

Configure OTS Controllers

The Optical Transport Section (OTS) controller holds all the optical parameters for the OTS optical interfaces. The optical interface has different capabilities depending on its hardware components such as photodiode, VOA, amplifier, and OCM.

There are multiple parameters for the OTS controllers. You can configure the parameters that are required for the different configuration for an OTS controller on an ILA node by using the following commands in the Ots controller configuration mode:

tx-voa-attenuation value
egress-ampli-gain-range {normal | extended}
egress-ampli-gain value
egress-ampli-tilt value
egress-ampli-osri {on | off}
egress-ampli-safety-control-mode {auto | disabled}
egress-ampli-force-apr {on | off}
raman-tx-power Raman-transmit-pump-instance power power-value
raman-tx-power-disable Raman-transmit-pump-instance

If you change the gain range from Normal to Extended or the opposite way, without updating the proper gain value for the new gain range, then the following may happen:

The EDFA switches to the preconfigured or default value of the gain causing a mismatch between the operational and configured gain.
The gain configuration is lost during the reload of software or line card, as the configured gain mismatches with the latest gain-range. This may result in traffic interruption during these reload operations.

Hence, we recommend that you explicitly configure the gain range mode as normal or extended, and the corresponding gain values for each mode to get the expected results.

The following are a few example scenarios that may not work as expected:

Scenario 1:

Current running config:

controller Ots R/S/I/P
 egress-ampli-gain-range extended
 egress-ampli-gain <gain value in extended mode>

New applied config:

controller Ots R/S/I/P
 no egress-ampli-gain-range extended
 commit

Scenario 2:

Current running config:

controller Ots R/S/I/P
 egress-ampli-gain-range extended
 egress-ampli-gain <gain value in extended mode>

New applied config:

controller Ots R/S/I/P
 egress-ampli-gain-range Normal
 commit

Scenario 3:

Current running config:

controller Ots R/S/I/P
egress-ampli-gain <gain value in normal mode>

New applied config:

controller Ots R/S/I/P
egress-ampli-gain-range extended
commit

The following is another example scenario that involves commit-replace command where you replace the existing gain configuration that does not have explicitly configured gain-range, with new gain-range and gain value.

Scenario 4:

Current running config:

controller Ots R/S/I/P
egress-ampli-gain <gain value in normal mode>

New applied config:

…………..
controller Ots R/S/I/P
egress-ampli-gain-range extended
egress-ampli-gain <gain value in extended mode>

The actual range of amplifier gain set point depends on amplifier gain range.

Note

Gain is calibrated to line port and so the supported range varies in Raman variants (OLT-C-R, ILA-C-R, and ILA-C-2R) due to insertion loss by Raman amplifier.

RP/0/RP0/CPU0:ios(config)#optical-line-control controller ots 0/0/0/0 apc disable
RP/0/RP0/CPU0:ios(config)#commit

For more information on APC commands, see the section, "Configure APC".

To modify the attenuation value for an egress channel slice, use the following commands:

Note

The OTS controller commands do not support decimal inputs. The OTS controller commands consider the inputs to one decimal place for the parameter values. In the following example, the attn value for the egress-channel-slice 10 is provided as 100 to configure the attn value for the egress-channel-slice 10 to 10.0 dB.

Configure Partner Band IP Address

NCS1010 can be configured to operate in both C and L-band wavelengths to increase the capacity of optical fibers. This can be done by connecting the C-band OLT or ILA line cards to the L-band OLT or ILA line cards respectively.

To establish a connection between C and L-band nodes, configure the L-band peer IP on C-band node and C-band peer IP on L-band node using the following commands in the Optical Line Control configuration:

optical-line-control

controller ots Rack/Slot/Instance/Port

partner-band-port ipv4 address ip-address controller ots Rack/Slot/Instance/Port

Example

The following output displays the peer node L-band IP address 192.168.1.2 is configured on the C-band node.

RP/0/RP0/CPU0:ios#conf
Wed Jul  6 04:45:47.720 UTC
RP/0/RP0/CPU0:ios(config)#optical-line-control controller Ots0/0/0/0
RP/0/RP0/CPU0:ios(config)#partner-band-port ipv4 address 192.168.1.2 controller Ots0/0/0/0

Note

The above configuration needs to be made on all the C and L-band nods in the Optical Line Control configuration mode.

OTS-OCH Controllers

The OTS-OCH controllers are not created by default when the cards (NCS1K-ILA-2R-C, NCS1K-ILA-R-C, NCS1K-ILA-C, NCS1K-OLT-R-C, and NCS1K-OLT-C) are brought up. The LINE OTS-OCH controllers can be created using the hw-module command.

Optical Cross Connections

Optical Cross Connections can be configured only on OLT nodes. In these nodes, the OTS-OCH controller is not created automatically on the Add/Drop ports (COM side). The optical cross connect configuration defines the line side OTS-OCH channel as the source and creates an OTS-OCH controller on the Add/Drop port to which the cross connection is made. The channel ID must be the same for both the LINE side and COM side OTS-OCH controllers.

Flex Grid Validation

The following validations are performed before the hw-module configurations are committed:

The channel ID is any value 1–194.
The center frequency must be within the C-band spectrum , for the OLT-C cards. The frequency range is 191.3375-196.1750 THz.
The center frequency must be within the L-band spectrum, for the OLT-L card. The frequency range is 184.6153-190.8875 THz.
The supported channel width range is 25.000GHz to 4837.500 GHz. From Release 7.9.1, overlap of channels is permitted as Nyquist channels are supported. See #Cisco_Concept.dita_da0d66f6-405e-4db6-8845-1578e253f5bd__.
From Release 7.9.1, you can set the channel centre frequency and width with 1MHz resolution.

OSC Controllers

The Optical Service Channel (OSC) controller is used to represent the optical capabilities, configuration, and monitoring of the OSC laser. The corresponding Gigabit Ethernet interface is the child interface that represents Ethernet capabilities, configuration, and monitoring.

OSC provides a communication channel for traffic coming from a UDC port. OSC serves as a channel probe to check fiber continuity between two nodes. OSC provides remote node management functionality. OSC is generated and terminated on each line side. OSC-C operates at a frequency of 198.50 THz and OSC-L operates at a frequency of 184.450 THz.

Nodes with NCS1K-OLT-R-C or NCS1K-OLT-C, NCS1K-OLT-L cards have one OSC controller. To view the status of the OSC controller, use the following command:

Insertion loss for each port is calculated and the power values are displayed on the OMS controller for NCS1K-BRK-8 and OCH controller for NCS1K-BRK-24. Insertion loss per port for NCS1K-BRK-24 is 5.9 dBm and NCS1K-BRK-8 is 0.6 dBm. The NCS1K-MD-32O/E-C panels have a maximum insertion loss of 6.2 dBm for the respective Mux and Demux sections.

AINS

The Automatic-In-Service (AINS) feature allows the OTS, OMS and OCH controllers to automatically move to the automatic-in-service state after the system boots up. A soak time period is associated with the AINS state. By default, the soak time period is one minute. The controllers automatically moves to the In-Service state after the soak time period is completed. During the AINS maintenance window, alarms are not propagated to the EMS/NMS monitoring system.

Soak Time Period

Soak time period for the controllers to move from AINS to In-Service state is 1 minute. You cannot configure the soak time.

The AINS soak time period restarts when there are line card cold reloads or power cycles.

All alarms are suppressed during the AINS state. When the optical and ethernet alarms are raised on the port during the soak time period, the port remains in the AINS state. These alarms are not displayed in the output of the show alarms brief system active command but these alarms are displayed in the output of the show alarms brief system conditions command. When all the alarms clear, the port moves to IS state.

Displaying the AINS Configuration

AINS is supported for the COM side controllers on the OTS port. It is not supported for the line side OTS-OCH controllers on OLT and ILA cards. Afte the optical cross connections are configured, the COM side OTS-OCH controller boot ups in AINS state.

This example displays the OTS controller statistics with AINS Soak time running.

Headless Mode

The headless mode of operation allows Cisco NCS 1010 to operate errorless during software upgrades and when the controller card is either physically absent or in a failed state. For example, NCS 1010 operates in headless mode for up to 72 hours, during process restarts, controller reload, line card warm reload, line card FPD upgrade, or removal of the controller (Online Insertion and Removal (OIR)). During this time, traffic is not impacted, although the control plane is not up and running. However, you cannot provision anything nor view operational data with a nonfunctional controller. Performance monitoring data based on 15 minutes and 24-hour intervals are not supported with a nonfunctional controller.

OIR is done during the upgrade or replacement of controller cards. When you initiate an OIR, you cannot reach the NCS 1010 through any medium. When the OIR completes, the NCS 1010 becomes reachable.

You can initiate OIR on the controller unit for the following scenarios:

FPD upgrade failure
Software image update failure
Bootup failure

ASE Loading

The OLT card (both OLT-C and OLT-L) includes a Noise Loader (NL) EDFA, which acts as an Amplified Spontaneous Emission (ASE) or noise source. The NL connected to the 2x33 ports Wavelength Selective Switch (WSS) loads optical noise. The optical noise fills the Line-TX optical spectrum, when the provisioned optical channels are not available on the ADD- 1 RX, ADD- 2 RX, or COM (OTS0/0/0/2 - OTS0/0/0/33) ports. For more details about the ports, see OLT Functional Layout.

The CHANNEL-NOISE-LOADED alarm is raised when an OTS-OCH controller channel fails and the missing carrier power in the channel is replaced with internally generated ASE noise. The alarm is cleared automatically when the original traffic channel is restored and the temporary ASE noise is removed. For more details about the alarm, see CHANNEL-NOISE-LOADED.

Benefits of ASE Loading:

Completely populates the transmission spectrum at LINE-TX independent of the actual system traffic load, thereby easing the system regulation starting from the Day-1 of the installation.
The same channel load is maintained during channel failures or channel deletion, which makes the system tolerant to power transients.
System performances can be verified efficiently because the ASE pattern emulates the full spectrum load also for the nonlinear interaction in the fibers, such as Four Wave Mixing (FWM), Cross Phase Modulations (XPM), and Stimulated Raman Scattering (SRS). Also, gradual fiber degradation that affects utilization of full-fiber capacity can be tracked.
Keeps the system running the full-channel configuration, which makes the system be intrinsically stable and provide optimal performance.

How ASE Operates

The following is the list of operations that are performed as part of the ASE loading:

The NL emits a total power of 16 dBm, and generates a power-spectral density (PSD) that is approximately equal to –10 dBm/12.5 GHz at the WSS input port. The OCM7 port monitors profile of the generated ASE channel. A Variable Optical Attenuator (VOA) available between the NL and the WSS input port regulates the ASE channel level properly.
The controller sets a predefined value for the VOA so that the ASE channels that are obtained at the COM TX-1 port are equalized to the actual traffic channels to fill out the spectrum at the input of the fixed gain amplifier.
When the controller detects a missing channel, for example any failure on the ADD/ EXP ports, it sends an updated attenuation value to the OLT. The OLT applies this value as a new attenuation setpoint and executes the transition from ADDs/EXPs path to ASE in the impacted wavelengths, thus ensuring fast recovery of the initial total optical power on the LINE-TX port.
When the optical power is restored, the controller sends a restoration command to the OLT. The OLT executes the transition from ASE to ADDs/EXPs in the impacted wavelengths ensuring minimal total optical power disturbance on the LINE-TX port, thus allowing a smooth fade-out of the ASE.

How ASE Is Managed

The default target ASE Load Spectral Density (AL_SD) is set to 81% for the OLT-C card and 78% for the OLT-L card. This default AL_SD is defined based on the frequency grid at 75 GHz with the first channel centered at 191.375 THz for OLT-C card and 186.125 THz for the OLT-L card. The spectrum is allocated through logical bins with 3.125-GHz width such that each physical slice is associated to two bins. Based on the above, the first ASE channel for the OLT-C card has:

Bins 1 and 2 blocked (frequency range 191.33750 – 191.34375 THz)
Bins 3–22 opened (frequency range 191.34375 to 191.40625 THz)
Bins 23 and 24 blocked (frequency range 191.40625 – 191.4125 THz)

The first ASE channel for the OLT-L card has:

Bins 13 and 14 blocked (frequency range 186.0875 – 186.09375 THz)
Bins 15–34 opened (frequency range 186.09375 to 186.15625 THz)
Bins 35 and 36 blocked (frequency range 186.15625 – 186.1625 THz)

All the other ASE channels are defined similarly by shifting all the settings by 75 GHz (24 bins).

Note

The ASE channels on the bins 1537–1548 and 1-12 are retained as blocked for Automatic VOA Shutdown (AVS) for the OLT-C and OLT-L cards respectively. In this AVS mode, the VOA is set at maximum attenuation value, when the channel is not provisioned to ensure the system reliability in case power is accidentally inserted.

Static ASE—At the system startup, without any channel provisioned, the complete ASE Load pattern is forwarded to the OLT LINE-TX port.

Dynamic ASE—When a traffic channel fails (for example, the PSD within the set of slices that are dedicated to the traffic channel is below a given threshold) an equivalent temporary ASE channel is inserted to maintain the spectral density on the line port. This dynamic ASE channel fills the original traffic channel with only a single slice guard band, at the beginning and the end. When the original traffic channel is restored, the temporary ASE channel is removed, and the original routing on the WSS is reestablished.

Dynamic ASE—With the Nyquist channels, dynamic ASE has the following behavior changes:

A minimum guard band of 6.25GHz is maintained between the active channel and the dynamic ASE, so the guard band of dynamic ASE will be 6.25 GHz + unused portion of the next user channel.
When there are two channels, and if channel 1 has failed and channel 2 overlaps channel 1, the dynamic ASE is filled in the slices other than the overlapping slices while leaving at least one slice as guard band.
If both channel 1 and channel 2 are overlapping and both have failed, dynamic ASE fills both the channels without leaving any guardband.
Static ASE and Dynamic ASE cannot overlap.

Optical Channel Monitoring

The Optical Channel Monitor (OCM) blocks in the OLT and ILA cards provide per-channel optical power monitoring.

The OLT-C card has a single OCM device with 37 OCM measuring points (OCM1 - OCM37). You can read the OCM data for the all the OCM blocks through the IOS-XR commands, except OCM1, OCM4, and OCM7.

The measuring points in the OLT-C card are:

LINE-TX
LINE-RX
2x33 ports of WSS in the multiplexer section of the OLT-C card

See OLT Functional Layout for details of the ports.
