Safety Requirements

ARRIS Telephony Modems comply with the applicable requirements for performance, construction, labeling, and information when used as outlined below
:
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.
Do not locate the equipment within 6 feet (1.9 m) of a flame or ignition source, to avoid damage or injury from battery explo­sion (i.e. heat registers, space heaters, fireplaces, etc.).
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 coax drop cable’s shield must be grounded at the building/residence either close to the point of entrance or at the point of attachment. It should be grounded as close as practical to the building/residence AC ground to minimize grounding connector length and thereby limit the po-
tential voltage differences between the cable TV coax cable and other grounding systems. Refer to the individual country’s Na­tional Electric Code for further details.
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.
CAUTION
Connecting the Telephony Modem to the home's 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.

Items You Need

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)
: as shown in the image to the left, 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
: as shown in the image to the left, 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.

Ethernet or USB?

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). Use the Ethernet connection if your computer has built-in Ethernet hardware, does not use Windows, or you want to share the Telephony Mo­dem connection with several computers.
Note:
To connect two or more computers to the Ethernet port, you will need a hub or broadband router (available at computer retailers).
The Telephony Modem package comes with a 6-foot (1.9m) 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 Modem di­rectly to a computer, or to an Ethernet hub or broadband router with a cross-over switch, ask for Category 5 (CAT5) straight-through cable. If you are connecting the Telephony Modem to an Ethernet hub or broadband router without a crossover switch, ask for a Category 5 crossover cable.
USB
USB (Universal Serial Bus) is meant for connecting a variety of accessories, such as keyboards, mice, printers, and communications devices (including Telephony Modems) to a single computer. Use the USB connection if you have only one com­puter, and the computer is using a Windows operating system (Windows 98 Second Edition or later), and has no built-in Ethernet hardware. The Telephony Modem package comes with a 5-foot (1.6m) USB cable.
Both
If you have two or more computers, you can connect one computer to the Telepho­ny Modem’s USB port and one or more other computers to the Ethernet port. To connect two or more computers to the Ethernet port, you will need a hub or broad­band router (available at computer retailers).
For more information about connecting two or more computers, contact your cable service provider.

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 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 connect your Telephony Modem to a wireless LAN, make sure you en­able security and encryption on the wireless hub (for the same reasons that you should run only secured proxies). Consult the documentation and tech­nical support of the wireless equipment provider for help.

Mounting the Telephony Modem

You can either mount the Telephony Modem on a wall or place it on a desktop. For wall-mount applications, you can mount the Telephony Modem with the indicators facing upward (vertical) or to the size (horizontal).
Tools and Materials
For wall-mounted installations, make sure you have the following tools and mate­rials before proceeding:
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)
Location
Always position the Telephony Modem:
within reach of an AC outlet. The power cord must reach the outlet without stretching and without adding extension cords.
near a cable outlet (to avoid long cable runs).
Note: When mounting the Telephony Modem on drywall, try to position the Te-
lephony 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.
To prevent overheating of the Telephony Modem, do not block the ven­tilation holes on the sides of the unit.

Connecting the Telephony Modem

WARNING: Connecting the Telephony Modem to the home's 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.
1 Connect one end of the coax cable to the cable outlet or splitter, and the
other end to the Telephony Modem’s Cable connector (F). Tighten the con­nections by hand, then tighten an additional 1/8 turn with a wrench.
Note: For best performance, use high-quality coax cable and minimize or eliminate splitters between the cable jack and the Telephony Modem.
2 Insert the plug from the power cord into the Power connector on the Tele-
phony Modem (G) and insert the power cord into a convenient AC outlet.
The Power light on the front of the Telephony Modem lights up, then flashes once (refer to the LED table on page 44). See Troubleshooting if the Power light does not turn on.
3 After connecting the coax cable and power, proceed as needed:
Making Ethernet Connections OR

Troubleshooting

Problems and Solutions

The Telephony modem is plugged in, but the Power light is off.
Check all power connections. Is the power cord plugged in firmly at both ends?
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.
I’m not getting on the Internet.
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.
Proceed to the Ethernet or USB solutions (next page) 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 or home router.
Press the Reset button on the back of the Telephony Modem.
I’m not getting on the Internet. (USB)
Did you load the USB drivers?
If you are using a powered USB hub, is the hub turned on?
Check the USB cable connections. Disconnect and reconnect the USB cable.
Restart the computer.
Press the Reset button on the back of the Telephony Modem.
I’m not getting on the Internet. (USB, Windows 98)
In some cases, Windows may install a “composite” USB driver instead of the ARRIS Telephony modem driver. To correct this:
Disconnect the USB cable between the computer and the Telephony Modem.
Use the ARRIS Remove utility (see Removing USB Drivers) to remove the improperly-installed driver.
Reboot the computer.
Reinstall the drivers as described in Installing USB Drivers on Your PC.
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.
If your Telephony Modem is connected to a LAN (Local Area Network), either directly or through a firewall, other communications on the LAN may slow down your connection.

I have two computers connected to the Telephony Modem, but only one can get on the Internet.
Check your cable company’s terms of service: they may allow only one com­puter to connect directly to the Telephony Modem.
I don’t have dial tone when I pick up my phone, why?
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.
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.
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.
Is the Telephone (Telephone 1 or Telephone 2) LED lit?
If not, phone service has not been provisioned 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
Is the Phone plugged directly into the Telephony Modem?
Make sure the phone is plugged into the port on the back of the Te-
lephony Modem labeled “Tel 1/2” (TM502G) or “Tel 1” (TM502A/B/H) 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.

Is the Telephony Modem plugged into a wall outlet?
If so, unplug the RJ-11 connector at the back of the Telephony Port
and plug in a known working phone. If you now have dial tone, the problem is with the house wiring. Contact your MSO or a qualified wiring technician to correct the house wiring. If you still do not have dial tone, contact your service provider.
