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.
