(Ethernet Cascading)
This section describes the typical fiber to the building (FTTB) or fiber to the curb (FTTC)
Ethernet cascading networks and typical hardware configurations of the access devices on the
networks.

Description
l The ONU is deployed in the building or
street fiber distribution terminal and uses
LAN or xDSL to connect to the HGW
placed at user's home.
l The HGW provides the Internet access,
IPTV, and VoIP services by connecting
to the upstream ONU using LAN or
xDSL. The built-in IAD of the HGW
provides the VoIP service.
On an Ethernet cascading network, users connect to the network through xDSL lines. An
optical network unit (ONU) using GE upstream transmission is used as a digital subscriber
line access multiplexer (DSLAM) and connects to a device on the metropolitan area
network (MAN). This is the mainstream networking of carriers. The data plan,
configuration, and maintenance of the ONU are the same as those of the existing DSLAMs
on live networks and therefore are not described in this section.
The recommended networking is as follows: ONU using GE upstream transmission ->
optical line terminal (OLT) -> MAN device. This is an FTTB or FTTC Ethernet cascading
network. The network of this type reduces optical fibers and operating expense (OPEX) of
carriers through O&M functions, such as remote software commissioning using GE
upstream transmission. An FTTB or FTTC Ethernet cascading network is available in one
of the following types:
– Independent NE networking: An ONU has a separate management IP address. The
operations support system (OSS) and U2000 manage the ONU as an independent NE.
– GE remote extended subrack networking in centralized management mode: An ONU
does not have a management IP address. Instead, it is managed as a GE remote extended
subrack (extended subrack for short) of the OLT (master subrack). The ONU is regarded
as a remote service board of the OLT. The network of this type applies if more users
need to be covered without increasing the number of NEs on the network. The GE
remote extended subrack networking reduces the OPEX and total cost of operation
(TCO) of carriers.
