When using traditional VDSL2 modems for user access:
–
For HSI service, users are provided with the HSI service through modems at their home.
Dialup authentication is required because modems are Layer 2 devices. Each user has
an independent account and is authenticated and managed on the BRAS.
–
For voice service, users are provided with the traditional telephone service by
connecting telephones to the VDSL2 splitter.
l
When using HGWs for user access:
–
The HGW is connected to the upstream extended subrack through VDSL2 ports, and
provides the Internet access service through FE or Wi-Fi ports and the IPTV service
through FE ports in the downstream direction.
–
The HGW has Layer 3 functions (such as PPPoE dialup and NAT), which enables
multiple PCs of a family to access the Internet at the same time.
–
The STB connected to the HGW provides IPTV program preview and access functions.
–
The IAD embedded in the HGW provides one or several POTS ports, which provides
access for multiple phones of a family at the same time.
Applicable master subrack: MA5600T, MA5603T (uses the SCUN board as the control board,
and is cascaded to the GE remote extended subrack through the ETHB board.)
Applicable GE remote extended subrack: MA5623AR

11.4.2.2 Principle of Data Planning for GE Remote Extended Subrack
Data planning for GE remote extended subracks covers security data, QoS data, and data about
the cascading between the master subrack and the extended subrack (including the reliability of
uplink links on the extended subrack).
