(gateway ONT)
Internet
l IPv4 address: An ONT obtains the IPv4 address
from the BRAS using PPPoE or DHCP. If IPoE
dial-up is used, the static address can be
configured. Meanwhile, as the DHCP server, the
ONT allocates private network IP addresses to
PCs. The NAT function enables these PCs to go
online by sharing the IPv4 address allocated by
the BRAS.
– The BRAS can allocate a public network IP
address to an ONT.
– The BRAS can allocate a private network
address to an ONT. The private network
address is translated to the public network
address by CGN (NAT44).
l IPv6 address: An ONT obtains the IPv6 address
from the BRAS using PPPoE, SLAAC, or
DHCPv6. If IPoE dial-up is used, the static
address can be configured. Meanwhile, the ONT
as the DHCP server obtains the prefix of an IPv6
address, and allocates IPv6 addresses to
connected PCs using the network cable or WiFi.
IPTV service
l If the IPv4 protocol is used, an STB obtains the
IP address from the BRAS using DHCP.
l If the IPv6 protocol is used, the STB obtains the
IP address in either of the following ways:
– Obtains the IP address from the BRAS using
DHCPv6.
– Obtains the IP address from the BRAS using
SLAAC.
VoIP service The IPv4 protocol is still used. The ONT functions
as the DHCP client to obtain an IP address from the
DHCP server, or the NMS issues a static IP address
to the ONT using the configuration file. Voice
media/signaling flows at multiple POTS ports share
one IP address. Media flows are classified by port.
TR069
management
The IPv4 protocol is still used. For scenarios in
which TR069 is required for management
maintenance and service provisioning, the ONT
functions as the DHCP client to obtain a public
network IP address from the DHCP server to
connect the TR069 server ACS.
