What features does Huawei ONT have?

Huawei ONT like HG8245, HG8546M, HG8247...Benifits

• Provides better and user experience
• Promotes the development of the OTT industrial chain for a win-win cooperation between carries and Internet companies.
• Provides fine-grained bandwidth management, which reaches a balance between investment, income, and costs.

Highlights

Smart Pipe
The smart pipe identifies OTT service based on the domain name or DIP, modifies the DSCP/PBit value of OTT services to differentiate them from common internet services , and provides a high-speed channel for OTT transmission. Therefore, the smart pipe helps carriers to manage bandwidths.

Carriers provide high-speed cloud storage services.

Users enjoy high-speed and stable cloud storage services.

Association of One Account with Two POTS Ports

• An Huawei ONT has multiple POTS ports but a household tend to have only one account. So, only one port is used. With the "Association of One Account with Two POTS Ports" function, you can use two POTS ports for calling through the same account.

POTS port 1 is for voice services and the phone number is 8888001. POTS port 2 is idle. The two phones can connect to POTS port 1 and port 2.

• The two phones can be connected to any POTS port on the ONT.

SoftGRE-based WIFI Sharing

1. SoftGRE tunnels are established on a dedicated logic WAN or through HSI WAN ports. The intermediate network devices are free of SoftGRE configurations, so the deployment is simple.

2, The carrier can lease excess, dedicated SSIDs to other carriers.
The service continuity during WIFI hot spot handover is supported.
Common WLAN: service continuity during WI-FI hotspot handover not supported.

SoftGRE: ONT HG8240F works with Huawei WI-FI gateways (e.g. Huawei ME60, a center router). When the terminal has moved and switched to another AP, the IP address is unchanged for service continuity.

Burst Optical/Electrical Technology on Huawei MA5600T MA5800

TDMA is used in GPON upstream direction. An ONU transmits data only within the allocated timeslots. In the timeslots that are not allocated to it, the ONU immediately disables the transmission of its optical transceiver to prevent other ONUs from being affected. The OLT then receives the upstream data from each ONU in a burst manner based on timeslots. Therefore, both OLT and ONU optical modules must support burst receive and transmit function to ensure normal running of the GPON system. Figure 2-16 shows the burst transmit function supported by ONU optical modules, and Figure 2-17 shows the burst receive function supported by Huawei MA5600T optical modules.

Ranging can be implemented to prevent cells transmitted by different ONUs from conflicting with each other on Huawei OLT MA5800. However, the ranging accuracy is ± 1 bit and the cells transmitted by different ONUs have a protection time of several bits (not a multiple of 1 bit). If the ONU optical modules do not support the burst receive and transmit function, the transmitted signals overlap and distortion occurs.

• The distance from each ONU to the OLT varies and therefore the optical signal attenuation varies for each ONU. As a result, the power and level of packets received by an OLT at different timeslots various.
• If the OLT optical modules do not support the burst receive and transmit function, an error occurs when the optical signals sent by Huawei ONU/ONT with a long transmission distance and large optical attenuation are recovered on the OLT because the optical power level is less than thethreshold (only the signals with the optical power level greater than the threshold can be recovered). Dynamic threshold adjustment enables the OLT to dynamically adjust the threshold for optical power levels based on the strengths of signals received by the OLT. This ensures that all ONU signals can be recovered.

What Is P2P Optical Access?

Definition
Point-to-point (P2P) Ethernet optical access is a mode in which P2P Ethernet optical access boards provide GE, 10GE and FE ports and coordinate with downstream devices to implement various optical access solutions for users. The solutions include FTTC/FTTB, FTTH, FTTO, FTTM and D-CCAP.

Purpose

• P2P Ethernet optical access is specially applicable to residential communities with optical fibers routed. It provides a more flexible FTTx solution, especially integrated services, including video, voice, and data for users. This feature has the following advantages:
• Higher bandwidth. The FTTH solution implemented through P2P optical access can provide a higher bandwidth for users, meeting the requirements of high-end users.

• Lower costs. P2P Ethernet optical access boards support more cascaded DSLAMs, reducing FTTC/FTTB networking costs.
• Higher reliability. P2P optical access allows a higher reliability in the DSLAM cascading scenario through features such as inter-board aggregation, smart link, and ring check.
• More flexible scenarios. The P2P Ethernet optical access boards coordinate with a variety of downstream devices (such as the DSLAM, ONT, SBU, and CBU) to implement FTTC/FTTB, FTTH, FTTO, FTTM and D-CCAP. Huawei MA5800 configured with the P2P Ethernet optical access board can not only be directly connected to access terminals but also cascade Huawei DSLAMs in order to converge a large number of users.

Configuring IPv6 Services in the FTTB/C (No HGWs) Scenario

Application Scenarios
The FTTB/C (no HGW) networking supports the access of IPv6 HSI services. Generally, no
IPTV services will be deployed when there is no HGW.
As shown in Figure below, the ONU, which is installed in a corridor or street optical
distribution box, transmits services to users through category-5 cables (LAN access) or
twisted pairs (xDSL access). Huawei OLT MA5600T and ONU work with upper-layer devices to support
Huawei DS+NAT+PPPoE/DS+NAT+IPoE HSI IPv6 solutions.

• For voice services: The ONU with a built-in voice module can directly provide VoI services for users. The ONU processes VoIP services using the IPv4 protocol instead of the IPv6 protocol.
• For Internet access services: Users connect to the ONU through category-5 cables (LAN access) or the modem and twisted pairs (xDSL access). The PC and BRAS support the IPv4/IPv6 DS and can be connected in the PPPoE or IPoE mode. Huawei OLT and Huawei ONU implement Layer 2 forwarding, irrespective of whether the access service is IPv4 or IPv6. Service configurations for IPv4 and IPv6 are the same. Only the ACL, anti-IP spoofing, and DHCP option configurations for IPv4 and IPv6 are different

Data Planning
This section describes the security, device management data, QoS, Internet service data, and
voice service data planning.
Security Planning
Security planning includes system security, user security, and service security, ensuring that
user services are provided properly from different dimensions.
In the FTTB/C (no HGW) networking scenario, the data for IPv6 and IPv4 security planning
differs only in anti-IP spoofing and DHCP option.
Anti-IP spoofing: This function needs to be configured separately for IPv6 services.
The anti-IP spoofing function can be enabled or disabled at three levels. This function takes
effect only when it is enabled at all the three levels.
1. Global level: Run the security anti-ipv6spoofing enable command in global config
mode.
2. VLAN level: Run the security anti-ipv6spoofing enable command in VLAN service
profile mode.
3. Service port level: Run the security anti-ipv6spoofing service-port serviceport-id
enable command.
DHCP option: The DHCP option for IPv4 is DHCPv4 option 82 and for IPv6 is DHCPv6
option 18/37.
The DHCPv6 option18 and option37 functions can be enabled or disabled at two levels. This
function takes effect only when it is enabled at both levels.
1. Global level: Run the dhcpv6 option enable command in global config mode.
2. VLAN level: Run the dhcpv6 option enable command in VLAN service profile mode.

IPv6 Configuration on Huawei OLT MA5800

IPv6 Networking

The FTTH IPv6 solution is part of the Huawei fixed broadband solution for IPv6, supporting
the access of the IPv6 high speed Internet (HSI) service and IPTV service.
The Huawei FBB solution for IPv6 includes the following scenarios based on service access
modes. Since "HSI scenario: IPv4/IPv6 DS+PPPoE+L2TP" and "HSI scenario: IPv4/IPv6 DS
+NAT+PPPoE" in this solution are the same as those in Huawei FTTx solution, they are not
elaborated in this document.

• HSI scenario: IPv4/IPv6 DS+NAT+PPPoE
• HSI scenario: IPv4/IPv6 DS+NAT+IPoE
• HSI scenario: IPv4/IPv6 DS+PPPoE+L2TP
• HSI scenario: DS-Lite+PPPoE
• IPTV scenario: IPv4/IPv6 DS+IPoE
• IPTV scenario: IPv4/IPv6 DS+PPPoE

The access network devices still use IPv4, instead of IPv6, to implement voice services.

Configuration Difference Between IPv6 and IPv4

The main configuration difference between the IPv6 and IPv4 services lies in the
configurations on Huawei OLT, MDU, and ONT.

Configuration Differences Between IPv6 and IPv4 on the OLT

Configurations between IPv6 and IPv4 on the OLT vary in the ACL, security feature, and
IPTV multicast service.

ACL
ACL configurations on the OLT are different for IPv6 and IPv4 on the network which runs
both IPv4 and IPv6 services, irrespective of the networking scenarios and service
implementation schemes. When configuring basic and advanced IPv6 ACLs, ensure that the
keyword "ipv6" is included in the configuration command.

Security Feature
Anti-IP spoofing configurations for IPv6 and IPv4 are different on the network which runs
both IPv4 and IPv6 services, irrespective of the networking scenarios and service
implementation schemes. If the IPoE and DHCP protocols are used, DHCP option
configurations for IPv6 and IPv4 are also different.

The IP addresses in anti-IP spoofing configurations are different for the two services.
In the IPv4 configuration, DHCP option is DHCPv4 option 82. In the IPv6
configuration, DHCP option is DHCPv6 option 18/37.
The DHCP option function is used together with the RAIO function, which enables the
Huawei MA5800 MA5600T to include physical information (including RID and CID) of the user, such as the subrack/slot/port. In this way, the BRAS or DHCP server is able to perform user
authentication and tracing. When DHCPv4 is in use, the OLT includes RID and CID to
the option 82 field. When DHCPv6 is in use, the OLT includes the RID to the option 37
field in the DHCPv6 packet and the CID to the option 18 field. The sub option 7 and sub
option 9 functions of DHCPv4 option 82 are not supported by DHCPv6.

IPTV Multicast Service

The IGMP protocol configurations (used to implement the IPTV multicast service) for IPv6
and IPv4 on the OLT are different. IPv4 uses the IGMP protocol while IPv6 uses the MLD
protocol (the IGMP protocol for IPv6). The IPv4 multicast service can share VLANs with the
IPv6 multicast service; therefore, you can deploy the IPv6 multicast service in existing IPv4
MVLANs only by adding IPv6 multicast programs in the IPv4 MVLANs and in right profiles.
The configured parameters such as the bound right profiles and MVLANs can remain
unchanged.

Bridging + Voice ONT Network Scenario (GPON Access)

Service Requirements and Application Scenario
Service Requirements
Optical fibers are connected to user homes and triple play services are required. The following
provides detailed service requirements:
Internet access of multiple PCs in a home is supported.
Access of multiple telephones in a home is supported.
IPTV programs can be previewed and watched using STBs.
Service extension is supported and different services do not affect each other.
Proper service security is ensured.
– Internet access services are protected against unauthorized access, user account
theft or borrowing, MAC/IP spoofing, and malicious attacks.
– Voice and IPTV services are protected against MAC/IP spoofing, malicious attack,
and traffic flooding attacks.
Service faults are easy to locate and services are easy to maintain.
Application Scenario
The bridging+voice ONT like Huawei HG8546M  provides Layer 2 data (Internet and IPTV services) and VoIP services. This scenario provides transparent transmission channels and requires simple service configuration, so this scenario applies to Layer 2 networking.
For Internet services, a PC directly performs dial-up. Then, the upper-layer broadband
remote access server (BRAS) device authenticates and accesses the PC. The PC can also
access the Internet using the Dynamic Host Configuration Protocol (DHCP) or static IP
address.
For VoIP services, Huawei ONT with a bulit-in voice module encapsulates voice service
packets, and the OLT transmits them to the upstream next generation network (NGN) or
IP multimedia subsystem (IMS).
For IPTV services, the set top box (STB) obtains an IP address from the DHCP server
for ordering programs. The ONT transparently transmits the packets.

Configuration Process

Data Plan Principles for IP Addresses

Data Plan Principles for IP Addresses

Terminal Type:

1, Bridging+Voice ONT
Internet access:A PC obtains an IP address through PPPoE dialup. The ONT transparently transmits the packets.
VoIP:The ONT functions as a DHCP client and obtains an IP address from the DHCP server, or the NMS issues a static IP address to Huawei ONT using the configuration file. Voice signaling and media streams at multiple POTS ports share one IP address. Media streams are distinguished by port.
IPTV:The set top box (STB) obtains an IP address from the DHCP server for ordering programs. The ONT transparently transmits the packets.

2, Bridging ONT+HGW
Internet access:The HGW functions as a PPPoE client and obtains an IP address through PPPoE dialup. At the same time, the HGW functions as a DHCP server and allocates IP addresses to
PCs through the network cable and wireless fidelity (Wi-Fi) access. The ONT transparently transmits the packets.
VoIP:The HGW functions as a DHCP client and obtains an IP address from the DHCP server, or the application control server (ACS) issues a static IP address to the HGW using
TR069. Voice signaling and media streams at multiple Huawei POTS ports share one IP address. Media streams are distinguished by port. The ONT transparently transmits the packets.
IPTV:The HGW is configured with a bridging WAN port. The STB obtains an IP address from the DHCP server. The,HGW transparently transmits packets. The ONT also transparently transmits the packets.

3, Gateway ONT
Internet access:The HGW functions as a PPPoE client and obtains an IP address through PPPoE dialup. The ONT functions as a DHCP server and allocates IP addresses to PCs through the
network cable.
Wi-Fi access:l Layer 3 bridge Wi-Fi access service: A mobile equipment (ME) searches the SSID. After the ME is authenticated, the DHCP server assigns this ME the IP
address by IPoE. l Layer 3 route Wi-Fi access service: An ME searches the SSID. After the ME is authenticated, the DHCP address pool of an ONT assigns this ME the IP address and then
PPPoE dialup is automatically performed on the ONT such as Huawei HG8546M.
VoIP:The ONT functions as a DHCP client and obtains an IP address from the DHCP server, or the NMS issues a static IP address to the ONT using the configuration file. Voice signaling and media streams at multiple POTS ports share one IP address. Media streams are distinguished by port.
IPTV:The ONT functions as a DHCP client and obtains an IP from the DHCP server. At the same time, the ONT functions as a DHCP server and allocates IP addresses to STBs.

Huawei MA5800 Configuring Alarms

Alarm management on Huawei MA5800 includes the following functions: alarm record, and alarm setting. These functions help you to maintain the device and ensure that the device works efficiently.

Context

An alarm refers to the notification of the system after a fault is detected. After an alarm is
generated, the system broadcasts the alarm to the terminals, mainly including the NMS and
command line interface (CLI) terminals.
Alarms are classified into fault alarm and recovery alarm. After a fault alarm is generated at a
certain time, the fault alarm lasts till the fault is rectified to clear the alarm.
You can modify the alarm settings according to your requirements. The settings are alarm
severity, alarm output mode through the CLI.
When managing alarms on the GUI through the NMS, you can set filtering criteria to mask
unimportant alarms and events. Such filtering function facilitates the focus of the important

alarms and eliminates the load of the NMS.

Procedure

Clear alarms.
You can run the alarm active clear command to clear the alarms that are not recovered
in the system.
– When an active alarm lasts a long time, you can run this command to clear the
alarm.
– Before clearing an alarm, you can run the display alarm active command to query
the currently active alarms.
l Configure alarm level.
Run the alarm alarmlevel command to configure the alarm level.
– Alarm levels are critical, major, minor, and warning.
– Parameter default indicates restoring the alarm level to the default setting.
– You can run the display alarm list command to query the alarm level.
– The system specifies the default (also recommended) alarm level for each alarm.

Use the default alarm level unless otherwise required.
Configure alarm jitter-proof.
Run the alarm jitter-proof command to configure the alarm jitter-proof function and the
jitter-proof period.
– To prevent a fault alarm and its recovery alarm from being displayed frequently,
you can enable the alarm jitter-proof function to filter alarms in the system.
– After the alarm jitter-proof function is enabled, the alarm in the system is not
reported to the NMS immediately but is reported to the NMS after an alarm jitterproof
period.
– If an alarm is recovered in an alarm jitter-proof period, the alarm is not reported to
the NMS.
– You can run the display alarm jitter-proof command to check whether the alarm
jitter-proof function is enabled and whether the alarm jitter-proof period is set.
– By default, the alarm jitter-proof function is disabled. You can determine whether to
enable the function according to the running of the device.
l Set or shield the output of alarms.
Run the (undo) alarm output command to set or shield the output of alarms to the CLI
terminal.
– Setting the output mode of alarms does not affect the generating of alarms. The
alarms generated by the system are still recorded. You can run the display alarm
history command to query the alarms that are shielded.
– When the new output mode of an alarm conflicts with the previous mode, the new
output mode takes effect.
– The output mode of the recovery alarm is the same as the output mode of the fault
alarm. When the output mode of the fault alarm is set, the system automatically
synchronizes the output mode of its recovery alarm. The reverse is also applicable.
Filter alarms reporting to NMS.
Run the trap filter alarm condition command to filter alarms that the device reports to
the NMS through traps.
The filtering criteria can be alarm ID, alarm severity, alarm type, subrack ID, subrack ID/
slot ID, subrack ID/slot ID/port ID, VLAN interface, and NE.
To reduce alarms and avoid alarm storms, the system does not send alarms of some
Huawei ONT to the NMS. To query the filtering criteria of alarms and events in the system, run
the display trap filter command.
l Query alarm configuration.
Run the display alarm configuration command to query the alarm configuration
according to the alarm ID. The alarm configuration that you can query includes the alarm
ID, alarm name, alarm class, alarm type, alarm level, default alarm level, number of
parameters, CLI output flag, conversion flag, and detailed alarm description.
(Optional) Configure alarm policy for ONT.
In Huawei FTTH scenarios, you can configure the ONT alarm policy profile to configure alarms
for different service policies.
