Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Access, Terminals, Transmission
and Multiplexing (ATTM).
Introduction
An Optical External Network Testing Interface (ENTI) is a passive element that sits at the boundary between the
Access Network (AN) and the end user (subscriber's) in-house FITH Network.
From a certain point of view ENTI can be regarded as a testing demarcation point between the access network and the
wiring at the customer premises. External Network Testing Interface ENTI defines the point for testing the operator's
network while isolated from the customer's home wiring.

1 Scope
The present document defines the functional and technical characteristics applicable to the Optical External Network
Testing Interface (ENTI) terminated with Singlemode fibre which provides testing capability at the demarcation point
between the line of the FTTH operator's network and the customer's cabling inside the house.
The present document describes optical ENTI for new homes. An optical ENTI is positioned in a distribution space. It is
connected to an ONT by an optical terminated cord.
The home cabling is not considered in the present document.
The present document specifies the functional characteristics and performance requirements for the optical ENTI within
the subscriber premises and for the needs of the FTTH optical access network.
