line terminal (OLT) when a distributed cable modem termination system (D-CMTS) works as
a GPON extended frame on a Layer 2 telecom network. The MA5603T equipped with the SCUV,
GPMD, and SPUF boards is used as an example.

15.5.1 Home Service Networking
In home service (VLAN tag transparent transmission) networking, a distributed cable modem
termination system (D-CMTS) connects to cable modems (CMs) at user homes through radio
frequency (RF) ports and provides home services for users, including the cable TV (CATV)
service, Internet access service, and VoD service. This section describes how to configure the
optical line terminal (OLT) to provision the home services.
15.5.1.1 Service Requirements and Usage Scenario
Service Requirements
Users require the provisioning of the broadcast and TV services, Internet access service, and
VoD service. Broadcast and TV services can be provisioned immediately after the distributed
cable modem termination system (D-CMTS) hardware is connected. This section only describes
how to configure the Internet access service, and VoD service.
Usage Scenario
As shown in Figure 15-18, a D-CMTS is deployed on an optical node and cable modems (CMs)
are deployed at user homes. The CMs connect to radio frequency (RF) ports on the MA5633
through cables.
l Port 1 on CM connects to a PC to provide the Internet access service. A set top box (STB)
connects to the distributor to provide a backhaul channel for the VoD service.
l Users access the Internet through Dynamic Host Configuration Protocol (DHCP) dialup.
l The IP addresses of the CM, STB, and PC are assigned by the DHCP server and in different
network segments.
l The D-CMTS is used as a GPON remote extended frame. This reduces D-CMTS
management and maintenance costs and simplifies configurations.
