12.2.7 Principle of Reliability Data Plan

Reliability planning covers planning of equipment reliability and upstream/downstream
networking protection. Reliability planning helps to achieve high reliability of FTTO SOHO
and SME services.

Solution
PPPoE+ (PITP) is enabled
on OLT and MDU, and the
BRAS implements user
authentication based on
binding of the RAIO
information to the user
account.
Description
The system uses two main control
boards of the same model and
version. The two main control boards
work in the active/standby mode by
default. When the active main control
board fails, the system switches to the
standby main control board to
prevent service interruption.
A subrack is configured with two
power boards of the same model and
version, which back up each other.
When one of the power board fails,
the other power board can still
provide power supply to the device
and so the system can still work
properly.
