System Response

• The system displays the queried result when the command runs successfully.
• The following table describes the parameters in response to the display ont-profile profile-id 1 command.

  Parameter	Description
  profile-id	Indicates the ID of the ONT capability set profile.
  profile-name	Indicates the name of the ONT capability set profile.
  Number of POTS ports	Indicates the number of POTS ports. When the value is adaptive, it indicates adaptive mode, in which the number of POTS ports is set based on the actual number on the ONT.
  Number of ETH ports	Indicates the number of ETH ports. When the value is adaptive, it indicates adaptive mode, in which the number of Ethernet ports is set based on the actual number on the ONT.
  Number of VDSL ports	Indicates the number of VDSL ports. When the value is adaptive, it indicates adaptive mode, in which the number of VDSL ports is set based on the actual number on the ONT.
  TDM port type	Indicates the TDM port type. It can be E1 or T1 type.
  TDM service type	Indicates the TDM service type. It can be TDMoGEM type only, that is, TDM service over GPON encapsulation mode.
  Number of TDM ports	Indicates the number of TDM ports.
  Number of MOCA ports	Indicates the number of MOCA ports.
  Number of CATV UNI ports	Indicates the number of CATV ports on the user side. When the value is adaptive, it indicates adaptive mode, in which the number of CATV ports is set based on the actual number on the ONT.
  Mapping mode	Indicates the mapping mode between the service stream and the GEM port. In single-bridge mode, the mapping mode can be configured to VLANID, 802_1PPRI, or VLANID+802_1PPRI. The default mode is VLANID. In multi-bridge mode, the mapping mode can be configured to PORT ID. You can run the mapping-mode(gpon profile) command to configure the mapping mode. By default, the ONT supports the VLAN mapping mode. Each ONT can be configured with only one mapping mode.
  The type of flow control	Indicates the type of the flow control, which can be PQ, GEMPORT-CAR, or FLOW-CAR. When the PQ mode is used, you need to define the sending queue of the GEM port packets in the T-CONT. The T-CONT sends the upstream data strictly according to the queue priority. By default, there are eight queues (queue 0 to queue 7) in the system. Queue 7 has the highest priority and the traffic of this queue is assured first. When the GEMPORT-CAR mode is used, the ONT restricts the rate of data packets carried on the GEM port based on the flow control settings of the GEM port. When the GEM port carries multiple service streams, the default scheduling mode of the ONT determines whether the PQ scheduling, WRR scheduling, or PQ+WRR scheduling is used. If there are multiple GEM ports in the T-CONT, the scheduling mode of the data packets between the GEM ports is also determined by the default scheduling mode of the ONT. When the FLOW-CAR mode is used, the ONT controls all service streams carried on the GEM port one by one, which is more refined as compared with the flow control in the GEM flow control mode. After the flow control of the service streams is complete, the service streams are scheduled in the T-CONT queue. The scheduling mode is determined by the default scheduling mode of the ONT.
  Binding times	Indicates the binding times of the ONT capability set profile.

• The following table describes the parameters in response to the display ont-profile all command.

  Parameter	Description
  GPON Profile ID	Indicates the ID of the ONT capability set profile.
  Profile name	Indicates the name of the ONT capability set profile.
  Binding Times	Indicates the binding times of the ONT capability set profile.

Incorrect Configuration of an Added Wavelength

During expansion, service interruption occurs in a normal wavelength on an OTU board and the corresponding OTU board reports OTU2_LOF alarm because of the incorrect wavelength configuration of an added wavelength.

Product

OptiX OSN 6800

OptiX OSN 8800

Fault Type

Service Interruption

OTU2_LOF

Symptom

When a 192.20 THz wavelength is added for expansion between sites F and G, the services on the 192.10 THz wavelength between sites B and G are interrupted. In addition, the corresponding OTU board at site G reports an OTU2_LOF alarm.

Figure 1 The Channel allocation of office T in V Network

Figure 2 The internal fiber connections of site F in V Network

Cause Analysis

The possible causes of the fault are as follows:

• The 192.10 THz OTU boards at sites B and G are faulty.
• The 192.10 THz OTU board at site G receives excessively low optical power.
• A 192.10 THz wavelength is introduced between sites B and G, thus resulting in conflicting wavelengths.

Procedure

1. Query the alarms and performance events of the 192.10 THz OTU boards at sites B and G.
   1. The performance of the OTU board at site B is normal, but the OTU2_BDI and ODU2_PM_BDI alarms are generated on the board.
   2. The OTU2_LOF, OTU2_SSF, and ODU2_PM_SSF alarms are generated on the OTU board at site G, but the receive optical power on the WDM side of the board is proper.
   
   Considering that the line power does not change, it is determined that the services may be interrupted due to an OTU2_LOF alarm on the WDM side of the OTU board at site G. Thus, the OTU boards at sites B and G may be faulty.
2. Sites B and G are left unattended. Thus, the OTU boards at the two sites cannot be tested by performing a fiber loopback on each of them. To restore the services in time, perform a cold reset on the OTU board at site B.
   1. When the OTU board at site B is cold reset, no R_LOS alarm is generated on the WDM side of the OTU board at site G but the OTU2_LOF alarm persists. In addition, the receive optical power on the WDM side of the board decreases from –8 dBm to –9.5 dBm.
   2. After the OTU board at site B is cold reset, the fault persists.
   
   The OTU board at site G may receive an excess 192.10 THz wavelength based on the preceding information.
3. Disable the laser on the WDM side of the OTU at site B to check whether the OTU board at site G still receives signals with optical power of –9.5 dBm. Then, disable the laser on the WDM side of the OTU board at site G and find that the receive optical power of the OTU board at site B is –60 dBm and that a R_LOS alarm is reported.
   An excess 192.10 THz wavelength may exist on the fiber from site B to site G.
4. Ask the customer whether the customer adds a board or changes a fiber connection on the live network during the time when the fault occurs.
   1. Check whether the customer has added an OTU board and established the corresponding physical fiber connection at site F to provide a 192.20 THz wavelength between sites F and G.
   2. Query the wavelength information about the new OTU board at site F and find that the wavelength is 192.10 THz and that the new OTU board is physically connected to the M40 optical interface on the TN11M40 board.
   
   The services on an existing wavelength are interrupted because the wavelength on the new board is set incorrectly.

Result

The problem is resolved.

Reference Information

Conclusions and suggestions for this case are as follows:

The NG WDM equipment uses the TN11RMU9 board for wavelength multiplexing. Conflicted wavelengths will result if wavelengths are planned or configured incorrectly. In this case, services on the equipment will be interrupted.

The LQG board works abnormally and the board reports CLIENT_SF and R_LOC alarm due to incorrect clock configuration on the board.

Product

OptiX Metro 6100

OptiX Metro 6040

OSN6800

OSN 8800

Fault Type

CLIENT_SF

R_LOC

Symptom

On a network built with the OptiX Metro 6100, two GE services are configured between sites A and B. The LQG board reports a CLIENT_SF alarm on the channel with abnormal services. The services are not configured with protection.

Check for the history alarms in the data sent back by field engineers and find that the LQG board at site A is interconnected with the LQG board at site B and the two LQG boards report the transient R_LOC alarms.

Cause Analysis

The possible causes of the fault are as follows:

• The WDM system functions abnormally.
• The LQG boards are faulty.
• The clock source settings of the LQG boards are incorrect.

Procedure

1. Check the network topology, and find that the other boards on the same route work normally and the receive and transmit optical power of the two interconnected LQG boards are proper. Thus, rule out the possibility that the WDM system is faulty.
2. Query alarms on the two LQG boards and find that the boards report the transient R_LOC alarms for a long time. Then, query the clock source settings of the boards and find that two LQG boards are enabled to trace the line clock. See the following figure.
   

Result

The problem is resolved.

Reference Information

Conclusions and suggestions for this case are as follows:

The WDM-side clock source in the transmit direction of the LQG board is configured incorrectly and thus four channels of services are faulty.

As shown in the preceding figure, 1#LQG and 2#LQG are interconnected through their WDM sides and the WDM-side clock sources in the transmit directions of the two boards are configured as the line clock. In this manner, the WDM-side transmitter on 1#LQG traces the clock from 2#LQG and the WDM-side transmitter on 2#LQG traces the clock from 1#LQG. The WDM-side transmitters on the two LQG boards trace each other's clock and thus the clock signals deteriorate continuously. Consequently, exceptions occur on the WDM sides of the two boards and the services on the boards are affected. Generally, a transient CLIENT_SF, CLIENT_SD, ALM_ETH_PORT_TLOS, or ALM_ETH_PORT_RLOS alarm is reported on the client side of a board when an R_LOC or a B1_EXC alarm is generated on the WDM side of the board.

Logical Board of SLQ16 Cannot Be Added on T2000

The logical board of the SLQ16 cannot be created on the T2000. This fault is rectified after the logical board of the cross-connect board is changed.

Product

OptiX OSN 3500, Huawei MSTP

Fault Type

Others

Symptom

A customer fails to add the logical board of the SLQ16 on the OptiX OSN 3500, and the customer mentions that the cross-connect board is changed from the UXCSA to the SXCSA on site.

Cause Analysis

The SLQ16 is applicable only to the OptiX OSN 3500 of 200 Gbit/s cross-connect capacity. If the cross-connect capacity decreases to 40 or 80 Gbit/s, the SLQ16 fails to work normally. The SXCSA has the board version replacement function. If the original logical board is the UXCSA, the system considers that the cross-connect board is the UXCSA by default, rather than the SXCSA. As a result, the logical board of the SLQ16 cannot be added.

Procedure

1. Query the physical and logical boards in slots 9 and 10 on the T2000. All the physical and logical boards are the UXCSA.
2. This is because the customer does not change the logical cross-connect board after the replacement of the physical cross-connect board. Change the logical cross-connect board to the SXCSA. Then, the logical board of the SLQ16 is added successfully.

Related Information

None.

GPON Service Multiplexing

GPON encapsulation mode (GEM) ports and transmission containers (T-CONTs) divide a PON network into virtual connections for service multiplexing.

• Each GEM port can carry one or more types of service stream. After carrying service streams, a GEM port must be mapped to a T-CONT before upstream service scheduling. Each ONU supports multiple T-CONTs that can have different service types.
• A T-CONT can be bound to one or more GEM ports, depending on customers' data plan. On the OLT, GEM ports are demodulated from the T-CONT and then service streams are demodulated from the GEM port payload for further processing.

Service Mapping Relationships

• In the upstream direction,
  • An ONU sends Ethernet frames to GEM ports based on configured mapping rules between service ports and GEM ports. Then, the GEM ports encapsulate the Ethernet frames into GEM packet data units (PDUs) and add these PDUs to T-CONT queues based on mapping rules between GEM ports and T-CONT queues. Then, the T-CONT queues use timeslots for upstream transmission to send GEM PDUs to the OLT.
  • The OLT receives the GEM PDUs and obtains Ethernet frames from them. Then, the OLT sends Ethernet frames from a specified uplink port based on mapping rules between service ports and uplink ports.
  Figure 1 shows GPON service mapping relationships in the upstream direction.
  Figure 1 GPON service mapping relationships in the upstream direction
  
• In the downstream direction,
  • The OLT sends Ethernet frames to the GPON service processing module based on configured mapping rules between service ports and uplink ports. The GPON service processing module then encapsulates the Ethernet frames into GEM PDUs for downstream transmission using a GPON port.
  • GPON transmission convergence (GTC) frames containing GEM PDUs are broadcast to all ONUs connected to the GPON port.
  • The ONU filters the received data according to the GEM port ID contained in the GEM PDU header and retains the data only belonging to the GEM ports of this ONU. Then, the ONU decapsulates the data to Ethernet frames and sends them to end users using service ports.
  Figure 2 shows GPON service mapping relationships in the downstream direction.

Some Abnormal OLT GPON CLASS B+ Optical Modules at High Temperature

GPON Networking Applications

GPON is a passive optical transmission technology that applies in FTTx solutions, including fiber to the building (FTTB), fiber to the curb (FTTC), fiber to the door (FTTD), fiber to the home (FTTH), fiber to the mobile base station (FTTM), fiber to the office (FTTO), and fiber to the WLAN (FTTW), for voice, data, video, private line access, and base station access services. Figure 1 shows FTTx networking applications.

Figure 1 FTTx networking applications

The FTTx network applications in GPON access have the following in common: The data, voice, and video signals of terminal users are sent to ONUs, where the signals are converted into Ethernet packets and then transmitted over optical fibers to the OLT using the GPON uplink ports on the ONUs. Then, the Ethernet packets are forwarded to the upper-layer IP network using the uplink port on the OLT.

• FTTB/FTTC: The OLT is connected to ONUs in corridors (FTTB) or by the curb (FTTC) using an optical distribution network (ODN). The ONUs are then connected to user terminals using xDSL. FTTB/FTTC is applicable to densely-populated residential communities or office buildings. In this scenario, FTTB/FTTC provides services of certain bandwidth for common users.
• FTTD: uses existing access media at user homes to resolve drop fiber issues in FTTH scenarios.
• FTTH: The OLT connects to ONTs at user homes using an ODN network. FTTH is applicable to new apartments or villas in loose distribution. In this scenario, FTTH provides services of higher bandwidth for high-end users.
• FTTM: The OLT is connected to ONUs using an ODN network. The ONUs are then connected to wireless base stations using E1. The OLT connects wireless base stations to the core IP bearer network using optical access technologies. This implementation mode is not only simpler than traditional SDH/ATM private line technologies, but also drives down the costs of base station backhaul. FTTM is applicable to reconstruction and capacity expansion of mobile bearer networks. In this scenario, FTTM converges the fixed network and the mobile network on the bearer plane.
• FTTO: The OLT is connected to enterprise ONUs using an ODN network. The ONUs are connected to user terminals using FE, POTS, or Wi-Fi. QinQ VLAN encapsulation is implemented on the ONUs and the OLT. In this way, transparent and secure data channels can be set up between the enterprise private networks located at different places, and therefore the service data and BPDUs between the enterprise private networks can be transparently transmitted over the public network. FTTO is applicable to enterprise networks. In this scenario, FTTO implements TDM PBX, IP PBX, and private line service in the enterprise intranets.
• FTTW: The OLT connects to ONUs using an ODN network, the ONUs connect to access points (APs) using GE for WLAN traffic backhaul. FTTW is the trend in Wi-Fi construction.

Introduction to GPON

What Is GPON

PON is a point to multi-point (P2MP) passive optical network. GPON, a type of PON technology, is defined by ITU-T Recommendation G.984.x. Figure 1 shows a GPON network.

Figure 1 GPON network

IFgpon: GPON interface	SNI: service node interface
UNI: user to network interface	CPE: customer premises equipment

• The optical line terminal (OLT) is an aggregation device located at the central office (CO) for terminating the PON protocol.
• Optical network units (ONUs)/Optical network terminal (ONTs) are located on the user side, providing various ports for connecting to user terminals. The OLT and ONUs are connected using an optical distribution network (ODN) for communication.
• The ODN is composed of passive optical components (POS), such as optical fibers, and one or more passive optical splitters. The ODN provides optical channels between the OLT and ONUs. It interconnects the OLT and ONUs and is highly reliable.
  NOTE:

  The ODN network is passive, indicating that no optical amplifier or regenerator is deployed on the ODN network, thereby reducing maintenance costs of outdoor devices.

Why Is GPON Required

As the wide use of broadband services and fiber-in and copper-out development, carriers require a longer transmission reach, higher bandwidth, reliability, and lower operating expense (OPEX) on services. GPON supports the following functions to meet these requirements:

• Longer transmission distance: The transmission media of optical fibers covers up to 60 km coverage radius on the access layer, resolving transmission distance and bandwidth issues in twisted pair transmission.
• Higher bandwidth: Each GPON port can support a maximum transmission rate of 2.5 Gbit/s in the downstream direction and 1.25 Gbit/s in the upstream direction, meeting the usage requirements of high-bandwidth services, such as high definition television (HDTV) and outside broadcast (OB).
• Better user experience on full services: Flexible QoS measures support traffic control based on users and user services, implementing differentiated service provisioning for different users.
• Higher resource usage with lower costs: GPON supports a split ratio up to 1:128. A feeder fiber from the CO equipment room can be split to up to 128 drop fibers. This economizes on fiber resources and O&M costs.

ont gemport mapping

Function

The ont gemport mapping command is used to set up the mapping between the GEM port and the services on the ONT, or the mapping between a GEM port and the upstream data stream of the user port on the ONT. You can flexibly select a proper service stream transmission mode based on the mapping mode supported by the ONT. After the command is executed successfully, the mapping is set up. In this case, the GEM port can carry services.
The undo ont gemport mapping command is used to cancel the mapping between the GEM port and the services on the ONT.

When you need to manage multiple users of the same level and type carried on the Ethernet port in a centralized mode and map the service streams of multiple Ethernet ports to a specified GEM port, use this parameter. NOTE: You can configure the binding function for the ONT port by running the port-bundle command. A bundle group can be used only in the port mapping, port ID+VLAN ID mapping, port ID+802.1p priority mapping, or port ID+VLAN ID+802.1p priority mapping mode. Ports between bundle groups and ports between a bundle group and a non-boudle group cannot be mapped to the same GEM port. If the bundle group is specified and then the VLAN is specified, use the port ID+VLAN ID mapping mode. If the bundle group is specified and then the priority is specified, use the port ID+priority mapping mode. If the bundle group and the VLAN are specified and then the priority is specified, use the port ID+VLAN ID+priority mapping mode.	Numeral type. Range: 0-7.
vdsl	Indicates the port mapping mode in which you map the services on a VDSL port on the ONT to a specified GEM port. If the port is specified and then the VLAN is specified, use the port ID+VLAN ID mapping mode. If the port is specified and then the priority is specified, use the port+priority mapping mode. If the port and VLAN are specified and then the priority is specified, use the port ID+VLAN ID+priority mapping mode.	-
moca	Indicates the port mapping mode in which you map the service stream of a MOCA port to a specified GEM port. The MOCA port is an interface that supports the North America communication protocols. The MOCA port is used to transmit data and video signals concurrently through the coaxial cable, and splits the signals after the signals are transmitted to the user terminal. If the port is specified and then the VLAN is specified, use the port ID+VLAN ID mapping mode. If the port is specified and then the priority is specified, use the port ID+priority mapping mode. If the port and the VLAN are specified and then the priority is specified, use the port ID+VLAN ID+priority mapping mode.	-
vlan vlanid	Indicates the VLAN mapping mode in which you map the service stream of a specified VLAN to a GEM port. When you need to run the mapping-mode(gpon profile) command to configure the mapping mode to the VLAN mapping or combined mapping associated with VLAN and map the VLAN service stream to a specified GEM port, use this parameter. When running the mapping-mode(gpon profile) command to configure the mapping to the VLAN mapping mode, you need to configure this parameter only. When running the mapping-mode(gpon profile) command to configure the mapping to the VLAN ID+802.1p priority mode, you must configure this parameter and the PQ queue priority. When running the mapping-mode(gpon profile) command to configure the mapping to the port ID+VLAN ID mapping mode, you must configure this parameter and the actual port ID. When running the mapping-mode(gpon profile) command to configure the mapping to the port ID+VLAN ID+802.1p priority mode, you must configure this parameter, PQ queue priority, and actual port ID.	Numeral type. Range: 0-4095.
vlan untag	Indicates the VLAN mapping mode. To map service streams without a VLAN tag to a specified GEM port, use this parameter. A service stream without a VLAN tag exclusively uses a GEM port, and other service streams with a different VLAN tag are not allowed to use this GEM port.	-
priority priority	Indicates the priority mapping mode in which you map the service stream of a specified 802.1p priority to a GEM port. The larger the value, the higher the priority. When running the mapping-mode(gpon profile) command to configure the mapping to the 802.1p priority, you need to configure this parameter only. When running the mapping-mode(gpon profile) command to configure the mapping to the VLAN ID+802.1p priority mode, you must configure this parameter and the VLAN mapping. When running the mapping-mode(gpon profile) command to configure the mapping to the port ID+802.1p priority mode, you must configure this parameter and the actual port ID. When running the mapping-mode(gpon profile) command to configure the mapping to the port ID+VLAN ID+802.1p priority mode, you must configure this parameter, VLAN mapping, and actual port ID. When running the mapping-mode(gpon profile) command to configure the mapping to the IP ToS field mapping mode, you need to configure this parameter only.	Numeral type. Range: 0-7.
flow-car traffic-table-index	Indicates the index of the traffic table that is bound to the GEM port. When using this parameter, you must enter flow-car for the qos-mode command. The maximum traffic is determined by the traffic profile that is bound to the service stream. Before configuring the traffic profile, ensure that a required traffic profile is created by running the traffic table ip command. NOTE: The service stream refers to the service channel from the ONT to the OLT, which is different from the service stream created by running the service-port command.	Numeral type. Range: 0-1023.
traffic-table-name traffic-table-name	When using this parameter, you must enter flow-car for the qos-mode command. The maximum traffic is determined by the traffic profile that is bound to the service stream. Before configuring the traffic profile, ensure that a required traffic profile is created by running the traffic table ip command. NOTE: The service stream refers to the service channel from the ONT to the OLT, which is different from the service stream created by running the service-port command.	Character string type, a string of 1–32 characters.
iphost	Maps the service stream of a specified IPHOST port to a GEM port. The IPHOST port is used to carry voice services. When you need to map the service stream carried on the IPHOST port to a specified GEM port, use this parameter. The IPHOST is a special port. You can configure only one IPHOST port. Run the ont gemport mapping command to configure the mapping, which is not restricted by the mapping mode of the ONT.	-
ont-portid	Specifies an ONT port.	Numeral type. Range: 1-8.
e1 ont-portid	Maps the service stream of a specified E1 port to a GEM port. As a special port, the E1 port is not restricted by the ONT mapping mode. To map the service stream carried on the E1 port to a specified GEM port, you must configure the attribute of the GEM port to TDM.	Numeral type. Range: 1-16.
ippath ip-index	Indicates the IP path port. It identifies the IP address port configured by running the ont ipconfig command. The IPPATH port is used to carry voice services.	Numeral type. The valid range is as follows: SCUN/SCUB/SCUL/SCUF control board: OLT mode: 0-3 MSAN mode: 0-1 SCUH/SCUV/MCUD/MCUE control board: 0-3
transparent switch	Enables or disables the transparent transmission function in the mapping mode. After this function is enabled, the ONT transparently transmits all services in the mapping to the OLT. The OLT does not capture or process the services. When configuring the mapping mode, if the attribute of transparent transmission is not specified, the parameter will not be configured by default, which is displayed as an en dash (-).	Enumerated type. Options: enable and disable. Default value: disable.
tdm-vcl	Maps the service flow on the TDM VCL port to a GEM port.	-

Usage Guidelines

• Run the config command to enter global config mode, and then run the interface gpon command to enter GPON mode.
• Before setting up the mapping between the GEM port and the services on the ONT, ensure that the GEM port is bound to the ONT T-CONT.
• Each ONT can be in only one mapping mode, which is configured in the bound ONT capability set profile.
• The mapping modes supported by the ONT are determined by the capability of the ONT itself. The system supports the following four mapping modes:
  • In single-bridge mode:
    • Mapping based on VLAN
    • Mapping based on 802.1p priority
    • Mapping based on VLAN+802.1p priority
  • In multi-bridge mode: Mapping based on port ID
• If the ONT has only one Ethernet UNI port, the transparent transmission function in all mapping modes can be configured. If the ONT has multiple Ethernet UNI ports, the transparent transmission function can be configured only in the following mapping modes: mapping based on port ID, mapping based on port ID+VLAN, mapping based on port ID+VLAN+802.1p priority, and mapping based on port ID+802.1p priority.
• On the same ONT, mapping based on 802.1p priority and mapping based on VLAN or mapping based on VLAN+802.1p priority cannot be configured at the same time.
• On the same ONT port, mapping based on port ID+802.1p priority and mapping based on port ID, mapping based on port ID+VLAN, or mapping based on port ID+VLAN+802.1p priority cannot be configured at the same time.
• You can run the display ont gemport mapping command to query the mapping between the GEM port and the service on the ONT.
