While Planning for Service provisioning and Network Operations, Demarcation points should be
clearly defined between RSPs and Network operators.

Business Users are generally provided GE level connectivity and P‐to‐P connectivity is provided by
OLTs Ethernet Boards. Redundant connectivity is provided using 2 ports on OLT and it is preferred
to use single fiber bidirectional solution to save the fiber required for Business Users connectivity.
To provide connectivity to Business Users MDUs are preferred choice at customer end, as they
provide abundant types of interfaces for Voice, Data and Video Transmission. In Scenarios where
end Business user only requires Ethernet, specialized Ethernet switches can be utilized easily.
The following table contains an example of an Open Access Network design (including GPON).
