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

Generation and Detection of Alarms and Performance Events in the SDH Higher Order Signal Flow

The principle for locating fault is "line first, then tributary; higher order first, then lower
order".
Therefore, this section focuses only on the alarms and performance events generated between
Huawei SDH interface and the cross-connect unit during maintenance. This section describes the
signal flow and the procedure for handling each overhead byte by each module.
Alarm signals generated between the SDH interface and Huawei cross-connect unit

Based on the positions of the various overhead byte processing in the STM-N (Huawei STM-64, STM-16, STM-4) frame, the overhead
bytes are classified into four modules:

• Regenerator section overheads
• Multiplex section overheads
• Higher order path overheads
• Lower order path overheads

If a fault occurs in the first two modules, it affects all the higher order paths. If a fault occurs in
the overhead bytes of a higher order path, however, it affects only this higher order path and its
lower order paths.
The following sections describe the signal flow and the processing of each overhead byte.
Downlink Signal Flow
In the higher order downstream signal flow, overhead bytes are extracted and terminated.
Frame Synchronizer and Regenerator Section Overhead Processor
Multiplex Section Overhead Processor
Pointer Processor and Higher Order Path Overhead Processor
Uplink Signal Flow
The overhead bytes are extracted and then terminated in the downlink signal flow of the higher
order path. Overhead bytes are generated and alarm signals are returned to the opposite NE in

the uplink signal flow of the higher order path.

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.

Planning the Optical-Path-Shared MSP

Capabilities of Supporting the Optical-Path-Shared MSP

When planning the optical-path-shared MSP for Huawei OptiX OSN 2500, first consider the
capabilities of supporting the optical-path-shared MSP.
In the case of the optical-path-shared MSP, one optical interface can be configured into two
MSP groups. Thus, multiple MSP rings can share the same fiber and optical interface.
The OptiX OSN 2500 supports the configuration of the optical-path-shared MSP.
l The SF16 and SL16 boards can process two sets of K bytes, which are located in the first
and fifth STM-1s. The SF16 and Huawei SL16 boards support configuring a single optical interface
into a maximum of two MSP rings.

Planning Principles

To rationally and effectively plan the optical-path-shared MSP protection, the planning
principles should be followed.

In normal situations, in the case of the optical-path-shared MSP, two low-rate line units share
the same high-rate line unit.

In the optical-path-shared MSP, two line STM-16 units at the same rate can share the same line unit.

When the optical-path-shared MSP is configured, on the protection ring, the optical interfaces

in two directions need not be configured into paired slots.

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.
