Chapter 31.
RG ONT
Introduction
This chapter considers issues related to configuration of Residential Gateway (RG) ONTs. The
chapter introduces the notion of Bridged and Routed services.
Consider the concept of OMCI and RG management domains. These terms are determined in TR-142
Issue 2. In terms of management domains, an ONT is considered as a device, which operates in the
OMCI domain only. The devices, which operate in both management domains (i. e. have an integrated
router), are denoted as ONT/RG. Everything that refers to the OMCI domain can be applied to both ONT
and ONT/RG devices. For this reason, we will further denote ONT/RG as ONT. If an ONT is configured
without the RG domain (without a router), skip all steps concerning RG.
Fig. 31.1 shows an ONT/RG scheme and its management domains.

Bridged service is a service, which configuration requires the OMCI management
domain only, i. e. it can be completely configured with the help of the OMCI protocol
in ONT.
Routed service is a service, which configuration requires both the OMCI and RG
management domains.
In addition to configuration in terminal, a routed service requires the RG domain to be configured by
using one of the following methods:
1. Pre-defined configuration—subscriber is provided with an ONT having fixed configuration.
