ONT G-25E Hardware Installation Manual

1.

Product Description

1.1

Introduction

Optical Network Terminal (ONT) model G-25E is an ITU-T G.984 compliant device that receives

voice, data, and video traffic in the form of optical signal from the service provider’s passive

optical network (PON) and transmitted it to the desired format - voice, data, or video - at

residential or business premises.

Upstream traffic is likewise transmitted to the PON network via the fiber optic cable. A single

optical fiber carries both upstream and downstream traffic.

1.2

Services

Equipped with ITU-T G.984 compliant 2.5G Downstream and 1.25G Upstream GPON UPLINK

interface, ONT G-25E supports the full Triple Play of services including voice, video (IPTV/VOD),

and high speed internet access.

ONT G-25E is equipped with the following service interfaces

1

:

z

Four 10/100 Base-T Ethernet ports for high speed internet access and IPTV/VOD services

z

Two POTS (VoIP) service ports for voice services

ONT G-25E has built-in capability for remote management like supervision, monitoring, and

maintenance.

1.3

Features

The ONT incorporates the following features:

z

Single fiber GPON interface with 1244Mbit/s upstream and 2488Mbit/s downstream data

rates

z

Advanced data features such as VLAN tag manipulation, classification, and filtering.

z

Traffic classification and QoS capability

z

Analog Telephone Adapter (ATA) function integrated based on SIP (RFC3261), with various

CLASS services supported - Caller ID, Call Waiting, Call Forwarding, Call Transfer, etc.

2

z

5 REN per line

z

Multiple voice Codec

z

Rich set of LED indications for alarming and maintenance

1

Some customized models may only provide a subset of service interfaces mentioned in this manual, for example, only four 10/100

Base-T Ethernet ports are provided.

2

These services may be unavailable within a specific carrier network and may require additional subscription.
