Chapter 1 Product Overview

1.1 Introduction

H3C VG 31-08 Voice Gateway (hereinafter referred to as VG

31-08) is a new-generation access device intended for enterprise and

small office, home office (SOHO) users. It integrates the access of

voice, fax, and data signals over Internet protocol (IP) networks,

functioning to transform analog voice or fax signals to IP data and

forward the data.

The VG 31-08 provides abundant IP telephony features, such as

one-to-one FXS-FXO port binding, emergency function, Voice over IP

(VoIP), Fax over IP (FoIP), call control, resource management, and

maintenance management, as well as multiple coding schemes. It

also supports DHCP Client, boasting excellent price/performance

ratio.

The VG 31-08 provides eight foreign exchange station (FXS)

ports, foreign exchange office (FXO) ports and one Ethernet interface.

FXS ports are used to connect analog telephones; FXO ports are used

to connect private branch exchanges (PBXes) through trunk lines; the

Ethernet interfaces are used to connect to the Internet.

Installation Preparations

Chapter 2 Installation Preparations

2.1 Site Requirements

The VG 31-08 is intended for indoor use only. To ensure normal

operation and longevity of your device, install it in an environment that

meets the requirements below.

2.1.1 Temperature/Humidity

You must keep the temperature and humidity in the equipment

room within a certain range. Long-term high humidity will lead to bad

insulation or even electricity leakage, mechanical property change,

and corrosion. However, too low relative humidity is likely to leave

captive screws loose due to contraction of insulation washers and

static electricity that threatens the CMOS circuit on the device. High

temperature accelerates aging of insulation materials and lowers

reliability and service life of your VG 31-08.

The following table lists temperature and humidity requirements

for the VG 31-08.

Table 2-1 Temperature/Humidity requirements in the equipment

room
