What is ONT?
ONT (Optical Network Terminal) is an optical network terminal, commonly known as an optical cat. It is a device that provides home users with access to the network. It can provide high-speed Internet access, IPTV, voice, and WiFi services.
Difference between ONT and ONU
ONT can be understood as ONU (Optical Network Unit), but in the strict sense belongs to ONU.
The difference between the two is that the ONT is an optical network terminal and is located directly at the user’s end; the ONU is an optical network unit, and there may be other networks between the user and the user, such as a gateway device under the ONU that can access xDSL or Ethernet access ports, and then Connect to a network terminal.
ONT position in the network
ONT is usually located in the user’s home, accessing various Internet access devices downwards, and accessing the network through optical fibers.
Huawei ONT Product Classification
Huawei’s common ONTs are roughly divided into traditional ONTs, intelligent ONTs, converged gateway ONTs, and 10G PON ONTs according to their functions.Among them, traditional ONTs can be divided into bridged ONTs and gateway ONTs according to their functions.
Bridged ONT
The bridge-type ONT is only responsible for transparent transmission, providing users with Internet access and IPTV channels, and can only connect to the network after dialing on user equipment such as a router or PC.Some bridged ONTs also support voice functions and can be connected to telephones.
If a bridged ONT is connected to a wireless router downstream, it can access the Internet wirelessly.
Representative products:
EchoLife HG8010H: Support 1 GE;
EchoLife HG8240H: Support 4 GE 2 POTS
Gateway ONT
Gateway ONT Compared with bridged ONT, it can realize routing and forwarding to automatically assign IP addresses, and users can connect to the network without dialing by themselves.Some gateway-based ONTs also come with dual-band WiFi (2.4G Hz & 5G Hz), which can provide wireless networks.
Representative products:
EchoLife HG8540M: Support 1 GE 3 FE;
EchoLife HG8247H: Support 4 GE 2 POTS CATV USB Wi-Fi
Intelligent ONT
The biggest difference between a smart ONT and a traditional ONT is that it can be used in conjunction with sensors (door sensors/smoke/water flooding / infrared alarms, etc.) to provide new functions such as real-time video monitoring, intelligent speedup, home control, etc., combining cloud platforms and intelligenceHome APP can also realize remote control of the smart home.
Representative products:
EchoLife HS8145V5: Support 1 phone 3 Gigabit 1 iTV 1 USB 2.4G & 5G Wi-Fi;
EchoLife HS8545M5: Support 1 phone 1 Gigabit 3 100M 1 USB 2.4G Wi-Fi
Converged Gateway
The converged gateway mainly integrates the STB function (iTV) on the gateway ONT, reduces the number of boxes, simplifies the installation, and supports 4K video. It is mainly used in hotel scenarios and a one-stop solution for Wi-Fi coverage and video experience.
Representative products:
EchoLife HS8125T: Support 1 GE 1 FE 1 POTS 2 USB 2.4G Wi-Fi 1 HDMI interface 1 Mini AV 1 infrared receiver infrared extension buckle 1 Micro SD card slot;
ChoEchoLife LS8025T: Support 2 FE 2.4G Wi-Fi 1 HDMI interface 1 Mini AV 1 infrared receiver infrared extension port
10G PON ONT
10G PON ONT’s user-side speed can reach Gigabit, which can not only meet the high-bandwidth services such as 4K / 8K high-definition video, AR / VR, home cloud, video calls for home users but also provide up to 10 Gigabit dedicated line access services.
Representative products:
EchoLife HN8245Q: Support 4 GE 2 POTS 2 USB 2.4G & 5G Wi-Fi
EchoLife HN8546Q: Support 4 GE 1 POTS 2 USB 2.4G & 5G Wi-Fi
Конфигурация gepon olt и ont — примеры первичной настройки olt и ont для оборудования bdcom
Схема организации сети
Перед началом настройки OLT убедитесь, что у вас актуальная версия прошивки
Актуальные прошивки можно скачать по адресу //data.nag.ru/BDCOM/Firmware/
Начальные условия следующие:
- один vlan на сервис, на каждый PON порт;
- входящий порт Ge 1/6;
- используемые vlan 5-управление, 11-14 Интернет, 20 – IPTV;
- IP для управления 10.10.0.0/24;
Зададим имя нашему OLT
hostname test-pon
создадим необходимые vlan
vlan 5
name mngm
vlan 11
name internet_1
vlan 12
name internet_2
vlan 13
name internet_3
vlan 14
name internet_4
vlan 20
name IPTV
Создадим IP интерфейс для управления
interface vlan 5
no shutdown
ip address 10.10.0.2 255.255.255.0
Добавим маршрут по умолчанию
ip default-gateway 10.10.0.1
Настроим авторизацию для управления
aaa authentication login default local
aaa authentication enable default none
Cоздадим пользователя admin с паролем passwd
username admin password 0 passwd
Создадим шаблон для конфигурации ONT T1, в нем vlan для интернет будем передавать в качестве параметра.
В шаблоне мы сделаем настройки:
1. Ограничим количество допустимых MAC от клиента 5
2. включим loopback detection
3. назначим multicast vlan
epon onu-config-template T1
cmd-sequence 1 switchport port-security dynamic maximum 6
cmd-sequence 2 switchport port-security mode dynamic

Для опроса уровней ONU по SNMP используем OID .1.3.6.1.4.1.3320.101.10.5.1.5.X, где X индекс нужной нам ONU
Найти индекс можно запросом ветки .1.3.6.1.4.1.3320.101.10.1.1.76 и нахожденим нужной ONU по МАС
MGMT-порт в модели 3310C не используется.
