Infinera Intelligent Transport Network Overview
Infinera Intelligent Transport Network Overview Infinera delivers the Intelligent Transport Network solution, referred to as the Infinera Intelligent Transport Network. The Infinera Intelligent Transport Network provides the ability to multiplex, transport, add, drop, groom, switch and protect OTN, SONET, SDH, Ethernet, and other services inexpensively, transparently, reliably, flexibly and quickly. The Infinera Intelligent Transport Network allows the construction of a single unified optical transport network that scales from metro to ultra long haul applications. In addition to the DTN-X, DTN, Optical Amplifier, XT, and FlexILS nodes, the Infinera Intelligent Transport Network provides system integration of the Infinera ATN®. The ATN is a Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM) multi-service platform that provides digital add/drop and bandwidth management capabilities. The Infinera Intelligent Transport Network is composed of DTN-Xs and DTNs deployed anywhere client access is desired and Optical Amplifiers where client access is not anticipated. The links between the DTN-Xs/DTNs, referred to as digital links, isolate analog engineering and impairments within that digital link. Users can progressively deploy the transport network with DTN-Xs/DTNs at more points of presence, interconnected by digital links, when and where capacity is required, without re-engineering the network. In addition to the digital links between DTN-Xs and DTNs, the Infinera Intelligent Transport Network also supports optical links between FlexILS nodes (including FlexILS ROADM nodes and DTN-X with ROADM nodes), and between FlexILS Optical Line Amplifiers, which are used for optical amplification of FlexILS services where client access isn’t required.
Infinera DTN-X The Infinera DTN-X combines the DTN’s photonic integrated circuit (PIC) technology with multi-terabit WDM transport and also integrates the technology with Optical Transport Network (OTN; ITU G.709) switching on the XTC chassis type. The DTN-X's non-blocking, ODU0 granularity single-stage switch fabric covers transport and bandwidth management applications across core, regional core, and large metro spaces. In addition, the DTN-X provides digital bandwidth management within an Intelligent Transport Network. It provides a means for direct access to client data at 40Gbps, 10Gbps, and/or 1Gbps digital granularity at a site, allowing flexible selection of whether to multiplex, add/drop, amplify, groom, optically express, or switch individual data streams. In addition to XTC chassis, the DTN-X can contain DTN, XT, OTC, and FlexILS chassis.
Infinera FlexILS ROADM Node The Infinera FlexILS ROADM is a reconfigurable optical add/drop multiplexer node, composed of two or more MTC-9/MTC-6 chassis configured with FRMs and IRMs/IAMs (one MTC-9/MTC-6, one FRM, and one IAM/IRM per degree). The FlexILS ROADM node provides colorless ROADM (optical express) functionality, and can also be used to provide dynamic spectral shaping, with each FRM dynamically equalizing the optical spectrum in one direction. The FlexILS ROADM supports reconfigurable optical add/drop multiplexer (ROADM) services with flexible grid and CDC capabilities to extend the optical reach between DTN-Xs deployed in an Intelligent Transport Network. The FlexILS ROADM node provides colorless ROADM (optical express) functionality, DTN and DTN-X Product Release Notes Release 20.0.1 V001

and can also be used to provide dynamic spectral shaping, with each FRM dynamically equalizing the optical spectrum in one direction.
Infinera FlexILS Optical Line Amplifier The Infinera FlexILS Optical Line Amplifier is an MTC-9 or MTC-6 based node used for optical amplification of FlexILS services.
Infinera XT The Infinera XT is a purpose-built, optimized platform for point-to-point hyper-scale bandwidth interconnect application across regional, metro, and long haul platforms. The XT combines the Infinera's coherent Dense Wavelength Division Multiplexing (DWDM) optical engine with a high port density packetbased Ethernet switch to enable multiple Tbps DWDM capacity over a single fiber pair. The XT is designed to simplify the deployment of high-bandwidth connections while lowering the power and space required for these networks.
Infinera DTN The Infinera DTN® provides digital ROADM service and bandwidth management capabilities within the Intelligent Transport Network. It provides a means for direct access to client data at a site, allowing flexible selection of whether to multiplex, add/drop, amplify, groom, optically express, or switch individual data streams. The DTN can be equipped in a variety of network configurations using a common set of circuit packs.
Infinera Optical Amplifier The Infinera Optical Amplifier is used to extend the optical reach between DTNs and DTN-Xs. The Optical Amplifier is composed of OTC chassis and is deployed at locations where customer access is not anticipated.

CHAPTER 5
Firmware Updates The components on the modules may contain several types of firmware:
■ Complex programmable logic device (CPLD)—CPLD firmware is not field upgradeable. It is
shipped with module and is not changed in the module in the field for the lifetime of the module. (Note that GNM may display different values for a module’s current CPLD and the “target” CPLD. If there is a difference in these values, this difference should be disregarded.)
■ Digital Signal Processor (DSP)— DSP firmware updates are automatic; they are not service
impacting and required no interaction to implement during upgrade. Table 5-2: DSE-1 Optical Power Monitor (OPM) Firmware Versions on page 5-4includes DSP versions for each module that are included in each release of IQ NOS. (Note that the DSP firmware may contain an FPGA, but the DSP updates are never service impacting and are always automatic.)
■ Field Programmable Gate Array (FPGA)—FPGA firmware updates are service affecting for certain modules (see Table 5-1: Module Types that Require Service-affecting Cold Resets for FPGA Firmware Upgrades on page 5-2). For all other modules, FPGA firmware updates are automatic and non-service affecting. For FPGA updates that are service-affecting and require a manual cold reboot, the SAFpgaUpgradeFlag will be displayed in GNM (in TL1, this is the SAFWUPG parameter in the RTRV-EQPT command response). In addition, for modules that require a cold reboot/service-affecting FPGA update, GNM will display the different values for current firmware version and target firmware version. (Note that it is acceptable if the current firmware version is higher than the target firmware version.) The following section further describes FPGA updates.

FPGA Firmware Updates
FPGA Firmware Updates Infinera has implemented Field Programmable Gate Arrays (FPGAs) within many of the hardware modules. These FPGAs support many different features and functions within the hardware and can be remotely upgraded in the field to add features or correct design inefficiencies without requiring replacement, repair and return of the hardware modules. Upgrade of the FPGAs is performed via updating the FPGA firmware or “image” - which is a list of programmable instructions that tell the FPGA how it should operate and what features it should provide. New FPGA images may (or may not) be provided within a new software release, and any enhancements to FPGA images will be identified within the Software Release Notes describing the functional change to the hardware that the FPGA image provides. FPGA firmware updates are classified into the following categories:
■ Optional—No major service improvements will be seen by upgrading the device firmware or the FPGA driver. It is recommended to upgrade this FPGA firmware only if service is not present . ■ Recommended—New features in the software rely on this code change, or Service Quality
improvements are provided as a result of this change. It is recommended to upgrade this FPGA firmware driver update if the new feature is required, or if the issue the FPGA firmware image was changed to address has been experienced.
■ Required—Service quality will be impacted if this FPGA firmware driver is not upgraded. It is highly recommended to upgrade this FPGA firmware driver at the first maintenance window opportunity.
FPGA firmware images where traffic or service continuity may be affected are not automatically updated as part of a system software upgrade. These images are updated on a user-commanded module cold reset, or on a module power-up initialization. This allows the user to make a decision if the FPGA upgrade is desired on a particular service path and implement the new FPGA firmware image during a planned maintenance window - or choose not to upgrade the FPGA firmware at all. To update the FPGA firmware image during a maintenance window, the user can control the time and place of a particular upgrade using the targeted cold-reboot commands in GNM, DNA, and TL1.

After a software upgrade to R19.0.3 or higher release, it is recommended to cold boot all the OXM2s in a Maintenance window for improved backplane performance. In a non-service affecting Maintenance window, start by cold booting the standby OXM2 and then perform a switchover. Cold boot the standby OXM2 again. Repeat the steps till all the 10 OXM2s gets cold booted in a chassis. Note: In case the XTC-10/XTC-4 contain OXMs, it is not required to cold boot the OXMs. Before upgrading to a software release, perform the following as applicable:
■ For all the node types, prior to Software upgrade, ensure that the Firmware version of all installed PONs are matching with the given software version
■ After a DTN-X network element is upgraded with empty database, perform a cold reset of PXM. ■ Prior to performing an IQ NOS upgrade, execute MOP 160319 to determine the DSP mode set on AOLM, AOLM2, AOLX, AOLX2 line modules and identify incorrect DSP Mode setting on the line module.

Issues Resolved in R18.2.1 Issue ID: 179713 Severity: Major Description: A difference in available bandwidth values is observed when 100G model licenses are applied on XT-3600 and XTS-3600 YB PONs. Issue ID: 182984 Severity: Major Description: When there is a LOS alarm on any of the configured carrier on ICE-4 LMs, if a Software upgrade is triggeredin this standing condition, the ICE-4 LMs will report an Equipment Degradation and Equipment Failure alarms. Issue ID: 181996 Severity: Major Description: In a multi-degree scenario in which multiple ICE4 line modules (XT-3600/XT-3300/ AOFx-1200) are connected with FRM through FBM, there is a possibility of traffic being impacted on the line module due to Auto Discovery between FBM and FRM. The line modules connected to provisioned FBM 8-8/FBM 8-4 ports 1A, 1B and any of the ports on FBM 8-2 are impacted. Depending upon the Rx power levels, when the power levels increase by >= 6 dB at the line module's line in port, the line module wrongly interprets this Auto-Discovery signal as OTDR pulses and disables RxEDFA which may bring down the traffic. During running operation, there is no risk of Auto Discovery leak originating from FRMs which are connected to FBM degree ports configured as lineoperatingmode=passive as no Auto Discovery signaling is triggered on such ports. As a preventive measure to avoid any chance of traffic impact, it is recommended in R18.2.0 to provision and Auto-Discover all the FRMs (node degrees) and FBMs in a node prior to connecting ICE4 Line Modules (XT-3600/XT-3300/AOFx-1200) and turning traffic on. Issue ID: 181582 Severity: Major Description: When creating a cross-connect on GNM for XT-3600, the destination end point takes a longer time (upto 1 min) to populate the line side AID.

Description: If an OTU facility loopback is present on a TIM-1-100G/TIM-1-100GM/TIM-1-100GX in ODU4 switching mode, on initiating an XCM switchover, the looped back traffic may be impacted. Workaround: None.
Configuration Management Issue ID: 124281 Severity: Major Description: In case of an L0-OPN configuration, if the BMM OCG Port is of OpenAutomatedExpress or Normal Express type, the user can lock the port and change the type to OpenAutomatedAddDrop even though the neighbor port is not locked. Due to this there is an incorrect configuration on the port with OCG Type set to OpenAutomatedAddDrop but OCG Mode set as Express. Workaround: It is recommended to lock the port and neighbor port before deleting the association to prevent this issue. To recover from this issue lock the neighbor port and delete the association on neighbor port. Issue ID: 122809 Severity: Major Description: In case of SLTE configurations, when traffic mode of a port is changed from Add/drop back to Express by locking the card (i.e max Add/Drop Port is changed), auto-discovery of the port times out. Workaround: Perform a warm reboot on the source FRM module to clear this issue. To prevent this issue, ensure that the port interface type is modified when the card is in maintenance state. Issue ID: 124501 Severity: Major Description: Whenever an OpenAutomated OCG is admin 'Locked' with shutter state 'open' and subsequently the BMM is cold rebooted, the Mux VOA comes up with 9dB and stays at the same value instead of 15dB which is a safe state value. This might cause power leakage, as input is always present. Workaround: Whenever any maintenance operation is performed, edit the shutter state to 'closed' and then perform a cold reboot. Issue ID: 124683 Severity: Major Description: On a Flex line system operating in SLTE Express configuration, if a warm reset of Mux FRM (i.e.Rx side FRM) card is issued with one of its port is in OLOS, then a subsequent auto discovery retrigger from the Demux FRM (i.e.Tx side FRM) will result in transmit auto discovery to timeout. Workaround: One more warm reset of the Mux FRM (i.e.Rx side FRM) will recover from the timeout and auto discovery will successfully complete. Issue ID: 124320

Workaround: Before cold booting a TIM, all SNCs originating from the TIM should be put in locked state and should be unlocked after the TIM has completed cold boot. Issue ID: 91951 Severity: Major Description: On triggering protection switch on a fully loaded chassis with around 50 one-port protection groups configured on a single OTM, there is a delay in reflecting the correct PU states in GNM. Workaround: None Issue ID: 90382 Severity: Major Description: For 100G TIMs configured with 2-port DSNCP protection and deployed in a back-to-back TIM configuration, switching time is around 500msecs for any protection switching action. Workaround: None Issue ID: 91450 Severity: Major Description: The protection switching time in case of protection groups on a fully loaded OTM or OLM module is around 50ms to 100ms. Workaround: Try to avoid loading a single OTM/OLM with protection groups. Create protection groups using TIM end points in different OTM/OLM in the chassis.

Configuration Management Issue ID: 68783 Severity: Minor Description: When the Base and Expansion card are installed in different chassis, if the Admin state is edited to Maintenance or Locked or if ARC is applied in the base BMM, alarms in the expansion BMM are not masked. Workaround: Apply Admin and ARC to both Expansion and Base BMMs. Issue ID: 71900 Severity: Major Description: The Optical Channel receive power readings for the SLM-80/AXLM-80/ADLM-80 may be incorrect. Workaround: Contact Technical Assistance Center (TAC) for further assistance. Issue ID: 78509 Severity: Major Description: During the XCM reboot, in certain rare cases, XCM may undergo additional warm resets which will result in more time for the XCM to come up. Workaround: None. The XCM comes up automatically once the warm reset is completed. Issue ID: 78509 Severity: Major Description: In rare scenarios, the XCM control module warm resets due to a software fault during the boot-up of the card before reaching the Active state. The card recovers autonomously after it is reset. Workaround: None. Issue ID: 91466 Severity: Major Description: Due to an IQ NOS defect, when an AOLM connected to a Gen1 BMM is locked at the head end, an OPR OOR Low alarm is raised in the express OCG instead of an BMM OCG OLOS alarm. Due to this incorrect alarm condition, the user cannot delete the express association. Workaround: To delete the optical express OCG, lock the BMM OCGs first and then delete the OCG associations. Do not lock the head end AOLM before deleting the express OCG connection. If the defect occurs, plug out the express OCG fibers, lock the express OCGs and then delete the OCG associations. Unlock the express OCG PTPs at the end. Issue ID: 88990 Severity: Minor

Description: For DTN-X, when two new Shelf Controllers are added to the Node Controller at the same time, the Node Manager does not provide the user with the capability to provision them readily. The user can only see one of the two chassis in GNM, and is required to complete provisioning that chassis. The user has to then wait for that chassis to be in service before moving on to provision the second chassis. Workaround: Disconnect one of the shelf controllers, physically connect one chassis to the network element to provision it as a shelf controller. After the first shelf controller is up and in service, the second shelf controller can be physically connected, recognized as a shelf controller and provisioned.
Turn-up, Testing, and Maintenance Issue ID: 67875 Severity: Minor Description: When the BMM OCG type is set to Manual in a SLTE Mode 1 BMM and no channels are selected, a value of 12dBm target OCG power is displayed by default which is incorrect. Workaround: None. Ignore these values until the channels are configured correctly and the BMM updates these values based on the link configuration. Issue ID: 62356 Severity: Minor Description: J0 trace messages are not cleared when a tributary PTP OLOS alarm is raised. Workaround: Ignore received J0 value when an OLOS alarm is raised on the TRIBPTP. Issue ID: 65000 Severity: Minor Description: LM-80 Active and LOS LED are turned OFF and immediately turned back ON when Warm Boot is in-progress. There is no other operation side effect. Workaround: Wait for some time till the LED states are steady. Issue ID: 68995 Severity: Minor Description: Using SLTE BMM2s with Auto-discovery completed with CMM and SLM-80, if the CMM OCG fiber is moved to a different BMM OCG for re-configuration, then the OCG association from the BMM OCG to the CMM OCG cannot be deleted. Workaround: Delete the OCG association before moving the fiber to different OCG.

Description: If an SNC is deleted and another SNC is created using the same ODU time slots, the Rx TTI field of the ODU retains the previous value received from the older SNC. Workaround: Create an ODU facility loopback on the downstream hop and clear the loopback.
Performance Management Issue ID: 76088 Severity: Minor Description: For 100GbE LAN interfaces where an LOA or LOLM condition is present, the PCS-SESS PM value increments. The PCS-SESS should increment only during Loss of Sync state, and not during LOA or LOLM condition. Workaround: Disregard the PCS-SESS values for 100GbE LAN interfaces with an LOA or LOLM condition. Issue ID: 81956 Severity: Major Description: When the incoming BER count increases on a TIM-1-100GE, a Local Fault (LF) alarm is raised but an additional high BER condition is not raised via Performance Monitoring thresholds. Workaround: None. Issue ID: 84858 Severity: Minor Description: The number of seconds in the 24 hour PM bin may not be accurate at times due to an NTP adjustment (triggered by a clock variation between oscillators in the cards or by a clock variation between cards). Workaround: None. Issue ID: 84394 Severity: Minor Description: When OLOS condition is present on a GAM-2 input port, the Optical Power Received PM parameter corresponding to the GAM does not display the correct value of -55dBm.

APPENDIX A:
Software Image Directory Structure The following section describes the Software Images and the directory structure.
Software Images Starting Release 16.2, the software image files required to install IQNOS software are split based on the chassis type. That is, every chassis type has its own software image file. The software image file is downloaded from the FTP server as described below:
■ The software image file is first downloaded for the main chassis. ■ The main chassis downloads the software image from the FTP server based on expansion chassis type. For all subsequent expansion chassis if the chassis type is the same, the software image is reused from already downloaded software image.
In Release 18.2, verified software image is implemented for the security of IQ NOS network elements to ensure integrity of Infinera software that are run on various platforms. This prevents systems from booting up with malicious software inserted in the images in an Infinera device. The verification process can be listed in the following sequence:
■ The software image includes a hash value - sha256 hash. ■ Management interfaces displays the hash of the downloaded image. ■ The user can manually compare the hash value displayed in management interfaces with the hash
present in the MetaR_..txt.sha256 file in the software image download directory. If the hashes match, the user can continue with the installation and upgrade. If the hashes do not match, it is left to the user to delete the downloaded image and retry.

In order for the software image to be downloaded the FTP server must be reachable at all times when any software maintenance operations are in progress. It is also required that the software image files are stored in a defined directory on the FTP server as described below: Starting R19.0, the chassis software image includes a tar ball which contains individual Field Replaceable Units (FRU) based tar balls for some FRUs and a tar ball for the controller card and remaining FRUs supported on that chassis. In Release 19.0.2, signed software image is implemented in XT(S)-3300/XT(S)-3600 network elements to ensure integrity and authenticity of Infinera software during software downloads and system boot up using Infinera Digital Signatures. The verification process of the signed image process can be listed in the following sequence:
■ The signed software includes a hash value - sha256 hash. ■ Management interfaces displays the hash of the MetaR file. ■ MetaR file contains hash of the all the image types and network element software internally verifies the hash of downloaded image with the hash in the MetaR file.
■ The user can manually compare the hash value displayed in management interfaces with the hash
present in the MetaR_..txt.sha256 file in the software image download directory. If the hashes match, the user can continue with the installation and upgrade. If the hashes do not match, the user has to delete the downloaded software image and retry.
Note: For software downgrade from a Release supporting FRU based images (R19.0 and later) to a Release that does not support FRU based images (Releases prior to R19.0) results in an unstable system. Ensure that the FTP server contains both the software "From" IQNOS version as well as "To" IQNOS version. FRU based installers are supported for the following: Table A-1 Software Image directory structure on FTP server Chassis Type
