ARRIS TOUCHSTONE WTM552 (01) PDF DOCUMENT

ARRIS Telephony Modems comply with the applicable requirements for performance, construction, labeling, and information when used as outlined below:

Potential equipment damage / Potential loss of service: Connecting the Telephony Modem to existing telephone wiring should only be performed by a professional installer. Physical connections to the previous telephone provider must be removed and the wiring must be checked; there must not be any voltages. Cancellation of telephone service is not adequate. Failure to do so may result in loss of service and/or permanent damage to the Telephony Modem.

Potential equipment damage: Do not locate the equipment within 6 feet (1.9m) of a flame or ignition source (e.g. heat registers, space heaters, fireplaces, etc.), to avoid damage or injury from battery explosion.

The Telephony Modem is designed to be connected directly to a telephone.

Connecting the Telephony Modem to the home’s existing telephone wiring should only be performed by a professional installer.

Do not use product near water (i.e. wet basement, bathtub, sink or near a swimming pool, etc.), to avoid risk of electrocution.

Avoid using and/or connecting the equipment during an electrical storm, to avoid risk of electrocution.

Use only power supply and power cord included with the equipment.

Equipment should be installed near the power outlet and should be easily accessible.

The shield of the coaxial cable must be connected to earth (grounded) at the entrance to the building in accordance with applicable national electrical installation codes. In the U.S., this is required by NFPA 70 (National Electrical Code) Article 820. This equipment is intended to be installed in accordance with the requirements of IEC 60728-11 for safe operation.

If the equipment is to be installed in an area serviced by an IT power line network, special attention should be given that the installation is in accordance with IEC 60728-11, in particular Annex B and Figure B.4.

In areas of high surge events or poor grounding situations and areas prone to lightning strikes, additional surge protection may be required (i.e. PF11VNT3 from American Power Conversion) on the AC, RF, Ethernet and Phone lines.

When the Telephony Modem is connected to a local computer through USB or Ethernet cables, the computer must be properly grounded to the building/residence AC ground network. All plug-in cards within the computer must be properly installed and grounded to the computer frame per the manufacturer’s specifications.

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

Telephony modem package: see ‘What’s in the Box?’ for a list of items in the package.

Coaxial cable (coax): This is a thin 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 Modem. The coax should be long enough to reach from your Telephony Modem to the nearest cable outlet.

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 Modem 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.

To use the Telephony Modem, you need DOCSIS high-speed Internet service from your cable company. The following describes requirements for each operating system:

Windows

Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows ME, Windows 2000, or Windows XP. A supported Ethernet or wireless LAN connection must be available.

MacOS

System 7.5 to MacOS 9.2 (Open Transport recommended) or MacOS X. A supported Ethernet or wireless LAN connection must be available.

Linux/other Unix

Hardware drivers, TCP/IP, and DHCP must be enabled in the kernel. A supported Ethernet or wireless LAN connection must be available.

To determine which model you have purchased, refer to the image of the modem’s underside in the user guide. The model number is on the label affixed to the Telephony Modem.

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

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 WTM552 through the Ethernet ports, you will need an Ethernet hub (available at computer retailers).

Wireless

The 802.11 wireless LAN standard allows one or more computers to access the WTM552 using a wireless (radio) signal. You can use the wireless connection if your computer has a built-in or aftermarket wireless card.

Both

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

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 your operating system 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 Modem. 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.

If you use the wireless LAN, make sure you enable wireless security on the Telephony Modem. See “Wireless Configuration” for help.

This model of the Telephony Modem has the ability to provide battery backup in the event of a local power loss. The 2.2Ah Lithium-Ion battery pack can be inserted into the Telephony Modem. Use this procedure to install and to replace the backup battery.

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

Is an AC outlet available nearby? For best results, the outlet should not be switched and should be close enough to the Telephony Modem 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 Modem. 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 Modem’s location and the phones?

If you are connecting devices to the Ethernet ports, can you easily run cables between the Telephony Modem’s location and those devices?

If you want to mount the Telephony Modem on a wall, does the location provide a solid surface for secure attachment? For best results when mounting the Telephony Modem on drywall, position the Telephony Modem so at least one of the screws are fastened to a stud. This may prevent the Telephony Modem from pulling out of the wall in the future.

If you want to install the Telephony Modem 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 Modem wireless connection range is typically 100-200 feet (30m-65m). A number of factors can affect connection range.

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

Increases range:

Raising the antenna above the devices (for example, installing the Telephony Modem in the upper floor of a multi-story dwelling or using an aftermarket omnidirectional antenna)

Using an aftermarket directional antenna (increases range in one direction while decreasing range in other directions)

Adding wireless hubs in a bridge (WDS) network

Decreases range:

Lowering the antenna below the devices (for example, installing the Telephony Modem in a basement)

Removing the antenna

Metal or concrete walls between the Telephony Modem and other devices

Large metal appliances, aquariums, or metal cabinets between the Telephony Modem and other devices

Interference and RF noise (2.4 GHz wireless phones, microwave ovens, or other wireless networks)

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.

You can either mount the Telephony Modem on a wall or place it on a desktop.

Tools and Materials for Wall-Mounting

For mounting on drywall: Two 1/4″ (6mm) drywall anchors and a drill with 1/4″ (6mm) bit (not included)

For mounting on plywood or studs: two #6 x 1.5″ (38.1 mm) self tapping screws (included)

Screwdriver (flat-blade or Phillips, depending on what kind of screws you use)

Wall-mount template (included with the Telephony Modem Quick Installation Guide)

Transparent tape (for temporarily securing the mounting template to the wall)

Wall-mounting instructions

1. Position the mounting template on the surface where you intend to mount the Telephony Modem and secure in place with transparent tape.

2. Drill holes through the template in the specified locations for the mounting screws. After drilling holes, remove the template from the surface.

3. If using drywall anchors, set them into the wall. Then, drive the screws into the wall leaving a gap of about 1/8″ (3 mm) between the screw head and the wall. If not using anchors, just drive the screws.

4. Orient the Telephony Modem with the indicator lights facing up or right, as desired. Slip both mounting slots (in the back of the Telephony Modem) over the screws, then slide the case down until the narrow end of the keyhole slot contacts the screw shaft.

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

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

Finally, check the fuse or circuit breaker panel.

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

Check the front panel lights:

The `Power` and `Online` lights should be on.

The `Link` light should be either on or blinking.

If the `Power` light blinks for more than 30 minutes, call your cable company for assistance.

Check your cable connections. Connectors should be finger-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 Modem and CATV outlet, remove the splitters and connect the Telephony Modem directly to the outlet.

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 `Router Reset` button on the back of the Telephony Modem.

A misconfiguration could lock out all access to the Telephony Modem router. If you think this has happened, see Resetting the Router to Factory Defaults.

Check the indicator lights – the WLAN 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 “WEP” or “disabled”. If you use “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 Modem router. If you think this has happened, see Resetting the Router to Factory Defaults.

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.

In order for telephone service to be functional on the Telephony Modem, telephone service must have been purchased from the service provider and configured on your Telephony Modem. 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 Modem is plugged in and the outlet has power.

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

2. Is the Online LED lit?

If not, check the coax connection at the Telephony Modem 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 (Telephone 1 or Telephone 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 Modem?

Make sure the phone is plugged into the port on the back of the Telephony Modem 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 Modem plugged into a wall outlet?

If so, unplug the RJ-11 connector at the back of the Telephony Modem 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.

Dynamic Host Configuration Protocol. An IP protocol used to provide an IP address and location of services (such as DNS and TFTP) needed by a device connecting to the network. DHCP allows the cable company to configure your computer’s networking software for you.

Data Over Cable System Interface Specification. The interoperability standards used for data communications equipment on an HFC network.

A hardware or software device that prevents unauthorized access to a private network from the Internet. The WTM552 provides a built-in firewall.

Service Set IDentifier, a string of text (up to 32 characters long) that uniquely identifies a wireless LAN.
