Chapter 1 Product Introduction

1.1 Overview

GT48 VoIP gateway is a product based on the advanced MicroXchange architecture. It is a multiple purpose,

modular VoIP gateway. GT48 is designed for carriers and enterprises for regular phone service, fax service and

PBX service. It can be used as a part of the cost effective IP PBX solutions.

GT48 supports many VoIP standard protocols and voice codec. It provides effective solutions to many technical

challenges that include echo cancellation, firewall, and billing. Compared to other products on the market, GT48

has the advantage of carrier reliability, flexible configuration, high voice quality, excellent protocol compatibility,

and low cost. Its high efficient hardware and software design and powerful DSP processing power guarantee the

GT48 capability of full load voice and signaling processing and IP packetization. Its redundant load sharing power

supplies and hot swappable modules further secures the GT48’s reliability.

GT48 can provide up to 48 FXS/FXO ports. It is also equipped with multiple 10/100M Ethernet interfaces. GT48

connects to regular telephones, faxes and PBXs through the FXS/FXO analog interfaces. It connects to IP

network through Ethernet interfaces. GT48 provides real-time and high quality IP-based voice services.

1.2 Features

GT48 has the following features:

¾Flexible Configuration

GT48 uses compact modular slot chassis design. Users can configure the GT48 with interface cards of different

types and capacities.

¾Carrier Reliability and Serviceability

GT48 hardware is designed to reach the high MBTF (Mean Time Between Failure). To satisfy the carrier

reliability requirement for voice gateways, GT48 has the option of load sharing power module. Should one power

module fail to function, the other power module resumes the full power function. Every hardware module is hot

swappable for in-service maintenance.

¾Support FTP file transfer and Telnet remote configuration

¾Protocols and Voice Codec

GT48 supports MGCP、SIP、RTP、TFTP、HTTP、SNMP、DHCP、and STUN protocols. It also supports G.711、

G.729A、G.723.1 codec, G.168 echo cancellation, RFC2833 DTMF relay, and T.38 fax relay.

¾Supported Devices

GT48 supports analog telephones, faxes, and PBX devices.

¾Interoperability

www.greatel.net -6-

GT48 has completed many Soft Switch and gateway interoperability tests worldwide.

Chapter 2 Modules and Interfaces

GT48 is designed based on modular architecture. Its modules and interfaces are followed:

2.1 Main Console Module

GT48 Main Console Module uses advanced framework and technology. Its main features include: high

performance processors for management and signaling processing and DSP sub module for voice processing.

The Main Console Module provides necessary interfaces to connect to peripheral devices and internal interface

modules. It can supports up to 48 analog line/trunk ports.

③Ethernet Port (0) ④Ethernet Port(1)

⑤Ethernet Port (2) ⑥Console Port (CON)

⑦Power LED ⑧Status LED

⑨Alarm LED ⑩Main Console Module Thumb Screw

GT48 modules are hot swappable for easy service and maintenance. For example: users can pull the main

console module out for service by pulling the main console module thumb screw indicated by ①and ⑩.

Note：The main console module can be secured by turning the screw clockwise. Turn screws the other way to

pull the main console module out.

2.1.1 FXO Port

There is on FXO port of RJ45 on the GT48 main console module.Table2-1 shows the wiring scheme for its

matting connectors.

RJ45 Wiring Scheme (8 pin) 4 5

RJ11 Wiring Scheme (4 pin) 2 3

The FXO port on the GT48 can be used for PSTN interconnection as a redundant path besides IP for voice calls.

Both RJ45 connector and RJ11 connector can be used for FXO port. When the RJ25 connector is used, pin 4

and pin 5 carry out the analog signal pair. When the RJ 11 connector is used, pin 2 and pin 3 carry out the analog

signal pair.

2.1.2 Ethernet Port

There are three 10/100M Ethernet ports on the GT48 main console module with RJ45 connector type and status

LED. Table 2-2 shows the pin assignment of those Ethernet connectors and LED status definitions.

Table2-2 Ethernet Port Pin Assignment and Status LED Definitions

TX+ TX- RX+ RX- Connected Live

¾Ethernet Port (0) ：reserved for future use.

¾Ethernet Port (1) ：for console/management/maintenance use.

¾Ethernet Port (2) ：VoIP broadband network interface. This port is used for all the VoIP activities that

include SIP and MGCP signaling protocol and RTP packets transmission. This port can also be used

for control/management/maintenance.

Note：If possible, we suggest customers use the Ethernet port 1 for software upgrade, device configuration, and

management operations and use the Ethernet port 2 for VoIP protocol and data transmissions.

2.1.3 Console Port

GT48 supports configuration through a console port (CON) of RJ45 connector type. Table2-3 shows the

connector interface scheme of RJ45 to DB9 and DB25.

DB25 Connector Pin No. 3 7 2

The console port is used for local management and testing. Computers can be connected to GT48 by linking the

RS232 port to GT48 console port. GT48 uses three wires on the console port: one TXD (send), one RXD

(receive), and one GND (ground).

GT48 is shipped with a standard RJ45 to DB9 cable.
