Hello, everyone!

Service Requirements

Optical fibers are connected to users' homes and triple-play services are required. The following provides detailed service requirements:

Internet access of multiple PCs in a home is supported.
Access to multiple telephones in a home is supported.
IPTV programs can be previewed and watched using STBs.
Service expansibility 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

As shown in Figure 1, the ONT integrating an integrated access device (IAD) provides Internet, VoIP, and IPTV services to users.

The bridging+voice ONT 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, the ONT with a built-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.
