2 TECHNICOLOR GATEWAYS

This chapter describes the Technicolor TG789VAC v2 DSL gateway, which is one of the modems/gateways used by AT&T

on DSL connections.

2.1 Technicolor TG789VAC v2 gateway

The TG789VAC v2 is an Integrated multi-mode ADSL/VDSL/FTTH gateway, supporting:

• ADSL over POTS for a TG789VAC v2 ADSL/POTS variant (Plain Old Telephone Service), an analogue telephone

line.

• ADSL/RE-ADLS2/ADSL2/ADSL2+

• VDSL2 with Vectoring technology

• Support for FTTH via Gigabit-Ethernet WAN port

• Firmware 10.5.8.U and later

• Auto-sensing for ADSL/VDSL2 and switches between them

• 4 ports Gigabit-Ethernet auto-sensing port for LAN connections.

• An USB-port to connect to a workstation or 3G USB stick.

• 2 FXS ports and VOIP functionality.

• Wi-Fi IEEE 802.11b/g/n/ac, will not be used in standard configurations, can be enabled via GUI and external

software.

The TG789VAC v2 gateway is a versatile device, which can be configured as a bridge or a router (or gateway) to suit all

different DSL environments. It has a built-in firewall which makes it possible to protect the LAN-side or Home network

from unauthorized access from the Internet.

Illustration 2.1: Technicolor TG789VAC v2gateway

The TG789vn supports several features, which are not supported by AT&T:

• Printer server function

• USB 3G function

• Voice over IP

• IPTV

These functions have been disabled.

The remaining LEDs will not be used.

Illustration 2.2: LED overview

The ports to connect all cables to are at the backside of the modem. The layout of the ports is displayed in illustration

2.3.

Illustration 2.3: The port layout of the TG789VAC v2

The ports used are the yellow 4-port switch and the gray DSL-port. In some circumstances the red GigabitEthernet port

is used for FTTH support. This connection must then be made to an external fiber-optic modem.

The power socket is located next to the power switch on the right hand side on the modem.

9

On the right side of the black power button the reset button is visible in a small hole.

2.2 Customized firmware

The TG789VAC v2 now uses a customized firmware which better suits AT&T requirements and gives better on-site

configuration support. Most important elements:

• The default user is now “ATTuser” , which after configuration only has user rights.

• The gateway WAN connection is auto-sensing for ADSL and VDSL2 and enables’ the required connectivity

models. No reboot is required.

• Embedded templates

◦ Bridge mode

◦ Austria; this model switches between ADSL with PPPoA to VDSL2 with PPPoE, and supports DHCP-

spoofing on both. This means the LAN attached client device can remain in DHCP mode and does not

need to be reconfigured. This device receives the public Internet address on its Wide Area Network

interface.

The configuration for specific countries will be done via external template files. These allow configuration as router

with support for Secure WiFi as well.

2.3 External configuration software

AT&T needs to support access in over 20 countries and wants to present the same hand-off and customer environment

in all situations. To support this AT&T has made external configuration software available via the AT&T global ftp

server, from which is can be downloaded. The software can be found via this URL:

ftp://ftp.attglobal.net/pub/MoW_Broadband/

The configuration options prepared are intended to support an ethernet attached IP VPN device for a small office or a

shop, or as standalone router with a dual-antenna wireless option. Both options can support IPv4 and IPv6 dual stack

environments. By default the AT&T IP DSL environment supports allocation of an IPv6 /128 prefix, and also a /60

Delegated IPv6 prefix to use for SLAAC or DHCPv6 IPv6 addressing on the LAN side of the router.

3 PHYSICAL INSTALLATION

This chapter describes the physical installation of the TG789VAC v2 Technicolor Gateway

model, hereafter called “DSL-device”.

3.1 Package description

The following items should be present in the Do-It-Yourself (DiY) package:

• 1 Technicolor TG789VAC v2 gateway box containing:

◦ 1 TG789VAC v2 modem

◦ 1 PSU

◦ 1 RJ11 cable

◦ 1 RJ45 Cat5e Ethernet straight cable

• Country localization kit containing

◦ 3 RJ 11 Straight Cables 2x 3 meters, 1x 5 meters

◦ 1 wall-socket converter if applicable

◦ 1 Splitter

◦ 1 PSU socket converter if applicable

◦ 1 Welcome letter

Examples of the RJ 45 and RJ-11 connectors:

Depending on the voice line present in the location, analogue or ISDN, the installation description differs. In some

countries the caretaker of the local loop, the actual wire-pair to the home, will install the splitter. If so, then this part

will not be included in the DiY package.

Figure 1 RJ-11 (left) and RJ-45 (right) connector.

The RJ-11 has 4 wires, the RJ-45 has 8 wires.

Page 11

3.2 Physical Installation Environment

The environment in which the DSL-device is being installed must have normal ventilation and support the following

conditions:

• Temperature: 0°to 40°C (32 to 105 F)

• Humidity: 20% to 80%

The DSL-device is passively cooled, so must not be placed directly on another heat-generating device.

Power requirements:

• AC voltage: 100 to 120, 220 to 240 V

• Frequency: 50/60 Hz

The adapter is auto-sensing for both voltage and frequency.

3.3 Connections Overview

The following paragraphs discuss the different installation options. Basically there are three options possible:

1. Splitterless , i.e. a direct connection from modem to wall socket

2. With a splitter (both POTS and ISDN)

3. Without a splitter (both POTS and ISDN)

Splitterless connectivity is also called “naked DSL”. It means there is no spectrum on the line supporting the classic

POTS phone service. If the connection is intended to support phone services, then these will consist of Voice over IP

and the phone will use a fxp port on the xDSL modem. This is not supported by AT&T. A direct connection from the

wall-socket to the modem is installed:

Figure 2 Splitterless installation for data-only xDSL access.

The connection of the RJ-11 cable to the wall-socket may require a converter to the local plug type. This should be

present in the localization kit. No line-sharing voice services are supported on the access connection.

POTS-splitters prevent high frequency energy from reaching the POTS device and to provide isolation from impedance

effects of the PORTS device on DSL. As the splitter is installed at the demarcation point, only 1 splitter is required for all

devices.

A POTS splitter has to be installed directly connected to the wall-socket, at the location where the phone line enters

the building, or at least between all devices and the demarcation to the telephone carrier.

Figure 3 Installation with a xDSL modem supporting line-sharing via a POTS-splitter

This picture in Figure 3 shows an example for a standard splitter. The splitter can differ per country. The splitter has 3

sockets, visible at the bottom of the illustration:

• The arrow on the left (blue) points to the socket for the phone line (RJ-11, 4 contacts), which comes from

your wall.

• The arrow in the middle (green) points to the socket for the DSL modem. This can be either an RJ-45 (8

contacts) or an RJ-11 (4 contacts) socket.

• The arrow on the right (red) points to the socket for your telephone cable (RJ-11, 4 contacts).

The device in Figure 2 states “splitter” clearly. This is not always so. If you do not know which type of splitter is

present, check the appendix A: “Country kits”.

An ISDN installation normally has an NT1 unit installed, which is the demarcation (or end-point) of the

Telecommunication company’s responsibility of the ISDN line. An ISDN-splitter has to be installed directly connected to

the wall-socket or ISDN line, at the location where the phone line enters the home, before the line enters the NT1 unit,

as displayed in Illustration 3.4 on page 14. In some countries this is handled by the local Telephone company or

licensed installation companies, in others the customer is permitted to do this.

1. Connect the NT1 cable to the ISDN splitter in the port marked “ISDN or Phone”. Your phone should now work

again.

2. Connect the RJ11 (or RJ-45) cable to the last free socket of the splitter (the top right on the picture) and

connect the other end of the RJ 11 (or RJ-45) cable to the DSL-device using the grey connector (see rear

picture of the modem on page 9).

3. Plug the RJ45 cable into your computer Ethernet port or into the WAN-port on the AT&T VPN Gateway or

Cisco Ethernet based routers for multi-user environments (see AT&T VPN Gateway user guide installation)

and connect the other end to the 1st yellow port of the modem (see the rear modem picture on page 9).

4. Connect the power cable to the rear of the modem (see rear picture page 9).

5. Plug the power supply to a 230V/50Hz or 110V/60Hz and to the modem.

Now the physical modem installation is done.
