Items You Need

If you are installing the Telephony Gateway yourself, make sure you have the following items on hand before continuing:

 Telephony Gateway package: see What's in the Box (page 10) for a list of items in the

package.

 Coaxial cable (coax): This is a round cable with a connector on each end. It is the same

kind of wire used to connect to your television for cable TV. You can buy coax from any electronics retailer and many discount stores; make sure it has connectors on both ends. There are two types of connectors, slip-on and screw-on; the screw-on connectors are best for use with your Telephony Gateway. The coax should be long enough to reach from your Telephony Gateway to the nearest cable outlet.

Note: For best performance, use high-quality RG-6 type coax cable and minimize or

eliminate splitters between the cable jack and the Data Gateway.

Chapter 3: Getting Started

 Phone Cable: This is a standard phone cable with standard phone connectors (RJ11 type)

on both ends. You can buy phone cables from any electronics retailer and many discount stores.

 Splitter (optional): provides an extra cable connection by splitting a single outlet into two.

You may need a splitter if you have a TV already connected to the cable outlet that you want to use. You can buy a splitter from any electronics retailer and most discount stores; you may also need a short piece of coax cable (with connectors); use it to connect the splitter to the cable outlet and then connect the Telephony Gateway and TV to the splitter.

Note: A splitter effectively cuts the signal in half and sends each half to its two outputs.

Using several splitters in a line may deteriorate the quality of your television, telephone, and/or internet connection.

 Information packet: your cable company should furnish you with a packet containing

information about your service and how to set it up. Read this information carefully and contact your cable company if you have any questions.

Getting Service

Before trying to use your new Telephony Gateway, contact your local cable company to establish an Internet account and telephone service. When you call, have the following information ready:

Chapter 3: Getting Started

 the Telephony Gateway serial number and cable MAC addresses of the unit (printed on

the Telephony Gateway)

 the model number of the Telephony Gateway (printed on the Telephony Gateway)

If the Telephony Gateway was provided by your cable company, they already have the required information.

In addition, you should ask your cable company the following questions:

 Do you have any special system requirements or files that I need to download after I am

connected?

 When can I start using my Telephony Gateway?  Do I need a user ID or password to access the Internet or my e-mail?  Will my phone number(s) change?  What new calling features will I have and how do I use them?

System Requirements

The Touchstone Telephony Gateway operates with most computers. The following describes requirements for each operating system; see the documentation for your system for details on enabling and configuring networking.

To use the Telephony Gateway, you need DOCSIS high-speed Internet service from your cable company. Telephone service requires that the cable company has PacketCable support.

About this Manual

This manual covers the Touchstone TG2492 Telephony Gateway. The model number is on the label affixed to the Telephony Gateway.

Chapter 3: Getting Started

1. Model Number

2. Security Label

What about Security

Having a high-speed, always-on connection to the Internet requires a certain amount of responsibility to other Internet users—including the need to maintain a reasonably secure system. While no system is 100% secure, you can use the following tips to enhance your system’s security:

 Keep the operating system of your computer updated with the latest security patches.

Run the system update utility at least weekly.

 Keep your email program updated with the latest security patches. In addition, avoid

opening email containing attachments, or opening files sent through chat rooms, whenever possible.

 Install a virus checker and keep it updated.

 Avoid providing web or file-sharing services over your Telephony Gateway. Besides certain

vulnerability problems, most cable companies prohibit running servers on consumer-level accounts and may suspend your account for violating your terms of service.

 Use the cable company’s mail servers for sending email.  Avoid using proxy software unless you are certain that it is not open for abuse by other

Internet users (some are shipped open by default). Criminals can take advantage of open proxies to hide their identity when breaking into other computers or sending spam. If you have an open proxy, your cable company may suspend your account to protect the rest of the network.

 The TG2492 ships with wireless LAN security set by default (for the same reasons that you

should run only secured proxies). See the security label on your product for the factory security settings. If you need to modify the default wireless security settings, see

Configuring Your Wireless Connection (page 23).

Ethernet or Wireless?

There are two ways to connect your computer (or other equipment) to the Telephony Gateway. The following will help you decide which is best for you:

Chapter 3: Getting Started

Ethernet

Ethernet is a standard method of connecting two or more computers into a Local Area Network (LAN). You can use the Ethernet connection if your computer has built-in Ethernet hardware.

Note: To connect more than four computers to the TG2492 through the Ethernet ports, you

need an Ethernet hub (available at computer retailers).

The Telephony Gateway package comes with one 4-foot (1.2m) Ethernet cable (the connectors look like wide telephone connectors); you can purchase more cables if necessary at a computer retailer. If you are connecting the Telephony Gateway directly to a computer, or to an Ethernet hub with a cross-over switch, ask for Category 5e (CAT5e) straight-through cable. CAT5e cable is required for gigabit Ethernet (Gig-E), not regular CAT5 cable.

Wireless

Chapter 3: Getting Started

Wireless access lets you connect additional (wireless-capable) devices to Telephony Gateway. The 802.11 wireless LAN standard allows one or more computers to access the TG2492 using a wireless (radio) signal. These connections are in addition to the connections supported via Ethernet.

Note: You can use the wireless connection if your computer has a built-in or aftermarket plug-

in wireless adapter. To learn more about which wireless hardware works best with your computer, see your computer dealer.

Both

If you have two or more computers, you can use Ethernet for up to four devices and wireless for the others. To connect five or more computers to the Ethernet ports, you will need an Ethernet hub (available at computer retailers.)

Chapter 4

Installing and Connecting your Telephony Gateway

Before you start, make sure that:

 You have contacted your cable company and verified that they provide data and

telephone service using standard DOCSIS technology.

 You have all the Items You Need.  Cable, phone, and power outlets are available near the computer. If a cable outlet is not

conveniently located, your cable company can install a new one.

If you have ordered service, your cable company should configure the Telephony Gateway automatically. You need only follow the instructions in this section to install and connect the Telephony Gateway.

CAUTION

Risk of equipment damage

Only qualified installation technicians should connect the Telephony Gateway to house wiring. Incumbent telephone service must be physically disconnected at the outside interface box before making any connections.

Raising the unit above the devices (for example, installing the Telephony

Selecting an Installation Location

There are a number of factors to consider when choosing a location to install your Telephony Gateway:

 Is an AC outlet available nearby? For best results, the outlet should not be switched and

should be close enough to the Telephony Gateway that extension cords are not required.

 Is a cable jack available? For best performance, keep the number of splitters between the

jack and cable drop to a minimum. Each splitter attenuates (reduces) the signal available to the Telephony Gateway. A large number of splitters can slow down the Internet connection and even affect your telephone service.

 Can you easily run cables between the Telephony Gateway’s location and the phones?  If you are connecting devices to the Ethernet ports, can you easily run cables between the

Telephony Gateway’s location and those devices?

 If you want to install the Telephony Gateway on a desktop, is there enough space on

either side to keep the vents clear? Blocking the vents may cause overheating.

 How close are your wireless devices? The Telephony Gateway wireless connection range is

typically 100–200 feet (30m–65m). A number of factors can affect connection range, as described below.

Desktop Mounting Instructions

Position the Telephony Gateway so that:

 it stands vertically on its base (Do not lay it flat on its side.)  air flows freely around it  the back faces the nearest wall  it will not fall to the floor if bumped or moved  the ventilation holes on the sides of the unit are not blocked

Factors Affecting Wireless Range

A number of factors can affect the usable range for wireless connections.

Increases range

Decreases range  Lowering the unit below the devices (for example, installing the



Gateway in the upper floor of a multi-story dwelling)

 Adding a wireless extender to the network

Telephony Gateway in a basement)

 Metal or concrete walls between the Telephony Gateway and other

devices

 Large metal appliances, aquariums, or metal cabinets between the

Telephony Gateway and other devices

 Interference and RF noise (2.4 GHz wireless phones, microwave ovens,

or other wireless networks)

Chapter 4: Installing and Connecting your Telephony Gateway

Note: Note that decreasing the range of your wireless network may be beneficial, as long as

the decreased range is sufficient for your needs. By limiting your network’s range, you reduce interference with other networks and make it harder for unwanted users to find and connect to your network.

Note: Setting the transmit power level to High increases the range. Setting it to Medium or

Low decreases the range proportionately.

Chapter 4: Installing and Connecting your Telephony Gateway

Wiring Problems

If the Telephony Gateway begins flashing all its lights for more than 10 seconds, this indicates a problem with the telephone wiring — the red and green wires may be shorted (touching), or there may be undesired voltage on the lines. If this pattern persists for more than 10 seconds, disconnect the telephone lines from the Telephony Gateway, then call a wiring technician for assistance.

Resetting the Telephony Gateway to Factory Defaults

To reset the router to factory defaults, press and hold the Reset button (4) on the back of the Telephony Gateway for more than fifteen seconds. This restores the wireless setup configuration and router configuration parameters to the factory defaults. You may need to do this if a misconfiguration has locked out all access.

Chapter 7

Troubleshooting

The Telephony Gateway is plugged in, but the Power light is Off

Check all power connections. Is the power cord plugged in firmly at both ends?

Note: Use only the external AC power adapter (if provided) and power cord included with the

equipment.

If you plugged the power cord into a power strip, make sure the strip is switched on.

Make sure that the rear panel power switch is set to the ON position.

Avoid using an outlet controlled by a wall switch, if possible.

Finally, check the fuse or circuit breaker panel.

I'm not getting on the Internet (all connections)

It may take over 30 minutes to establish a connection the first time you power up your Telephony Gateway, especially when many people are online. Always leave your Telephony Gateway plugged into AC power and connected to the cable system.

Check the front panel lights:

 The Power and Online lights should be on.  If the Power light blinks for more than 30 minutes, call your cable company for assistance.

Check your cable connections. Connectors should be tight. The coax cable should not be pinched, kinked, or bent sharply—any of these can cause a break or short in the cable (you may have to replace the cable). If you have one or more splitters between the Telephony Gateway and CATV outlet, remove the splitters and connect the Telephony Gateway directly to the outlet.

Proceed to the Ethernet or wireless solutions if necessary.

I'm not getting on the Internet (Ethernet)

If you are using a hub, is the hub turned on?

Are you using the right type of Ethernet cable? Use the supplied cable for direct connection to a computer; use a cross-over cable for connection to a hub.

Press the Reset button on the back of the Telephony Gateway.

Chapter 7: Troubleshooting

A misconfiguration could lock out all access to the Telephony Gateway router. If you think this has happened, see

Resetting the Telephony Gateway to Factory Defaults (page 36).

I'm not getting on the Internet (Wireless)

Check the indicator lights, see Using the Telephony Gateway (page 31) — the Wi-Fi light should be on.

Does your connection utility discover your wireless LAN? If you turned off “Broadcast SSID” you need to manually enter the name of your wireless LAN in the connection utility.

Change your security mode to “disabled”. Enable one of the other security modes as soon as you find the problem.

A misconfiguration could lock out all access to the Telephony Gateway router. If you think this has happened, see

Resetting the Telephony Gateway to Factory Defaults (page 36).

My wireless Internet connection stops working sometimes

This is usually caused by interference. Two common sources are 2.4GHz “remote” telephones and microwave ovens. If you cannot remove the interfering product, try using a different channel or setting Protected Mode.

I can get on the Internet, but everything is slow

If the Web site you are visiting is very popular, that site may be having trouble servicing all the requests. If other sites download quickly, wait for a few minutes and try again. Usage during peak hours may also affect the connection speed.

Other communications on the LAN, or interference with wireless connections, may slow down the connection.

I don't have a dial tone when I pick up the phone why?

In order for telephone service to be functional on the Telephony Gateway, telephone service must have been purchased from the service provider and configured on your Telephony Gateway. The following steps should help in identifying the source of the problem.

1. Is the Power LED lit?

• If not, check to make sure the Telephony Gateway is plugged in and the outlet has

power. Use only the external AC power adapter (if provided) and power cord included with the equipment.

• If the LED is lit, go to the next step.

Chapter 7: Troubleshooting

2. Is the Online LED lit?

• If not, check the coax connection at the Telephony Gateway and the wall. Ensure they

are connected and tight. If they are and you do not have dial tone, contact your service provider.

• If the Online LED is lit, go to the next step.

3. Is the Telephone (Tel 1 or Tel 2) LED lit?

• If not, phone service has not been set up on that line. Contact your service provider.

• If it is blinking, there is a phone off hook somewhere in the house. Find that phone and

hang it up.

• If it is lit, go to the next step.

4. Is the phone plugged directly into the Telephony Gateway?

• Make sure the phone is plugged into the port on the back of the Telephony Gateway

labeled “Tel 1” for line 1, and “Tel 2” for line 2.

• If so, try a different phone. Make sure the new phone is a working phone.

• If a known good phone is used and you still don’t have dial tone, try a different phone

cable. If a new phone and cable do not restore dial tone, call your service provider.

5. Is the Telephony Gateway plugged into a wall outlet?

• If so, unplug the phone connector at the back of the Telephony Gateway and plug in a

known working phone. If you now have dial tone, the problem is with the house wiring. Contact your cable company or a qualified wiring technician to correct the house wiring. If you still do not have dial tone, contact your service provider.
