18.1 Configuring Example of EoC Services (OLTs Use
GPON Access)
Ethernet over coaxial cable (EoC) is a key technology for the next-generation broadcast and TV
networks. This technology can be used to reconstruct the existing cable networks to bidirectional
broadband network to provide bandwidth services such as high-speed Internet (HSI) and Internet
protocol television (IPTV). This topic uses the MA5631 as an optical network unit (ONU) to
describe how to configure EoC broadband services.
Service Requirements
Users can subscribe to broadcast and TV services, Internet access services, and interaction
services. Broadcast and TV services can be provided after the ONU hardware is connected and
the service channel is set up. No configuration is required. This topic only describes how to
configure the Internet access and interaction services.
The CNU uses the HG7022, providing two LAN ports. Port 1 is connected to a PC for providing
the Internet access service and port 2 is connected to a set top box (STB) for providing a return
channel for the interactive TV service. The CNU differentiates services by port. Virtual local
area networks (VLANs) are not switched on the optical line terminal (OLT) and services are
transparently transmitted on the OLT.
l
Users access the Internet in Point-to-Point Protocol over Ethernet (PPPoE) dialup mode.
l
Policy Information Transfer Protocol (PITP) is enabled to protect user accounts against
theft and roaming.
NOTE
In Dynamic Host Configuration Protocol (DHCP) dialup mode, you can configure anti-theft and roaming
for user accounts. For details, see
Configuring Anti-Theft and Roaming for User Accounts Using
DHCP
