Items You Need
If you are installing the Telephony Modem yourself, make sure you have the fol-
lowing 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.
Note: For best performance, use high-quality RG-6 type coax cable and mini-
mize or eliminate splitters between the cable jack and the Telephony Modem.
•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 sin-
gle outlet into two. You may need a splitter if you have a TV already con-
nected 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.
•Wall-mount hardware (optional): if you want to wall-mount your Tele-
phony Modem, you need to obtain two drywall anchors or wood screws. See
the Wall-Mount Template and Instructions for more details.
•Information packet: your cable company should furnish you with a packet
containing information about your service and how to set it up. Read this in-
formation carefully and contact your cable company if you have any ques-
tions.

About this Manual
This manual covers all of the different TM822 models. Your model may not have all
of the capabilities outlined in this manual. To determine which model you have pur-
chased, refer to the image at the left. The model number is on the label affixed to
the Telephony Modem.
Ethernet Connection
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet
hardware or you want to share the Telephony Modem connection with several com-
puters. Arris recommends using an Ethernet connection.
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 5e (CAT5e) straight-through cable. CAT5e cable is required
for gigabit Ethernet (Gig-E), not regular CAT5 cable.

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 fol-
lowing 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 addi-
tion, 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 run-
ning 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). Crimi-
nals can take advantage of open proxies to hide their identity when break-
ing 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 net-
work.
• 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.

Wall-mounting instructions
Note: When mounting the Telephony Modem on drywall, try to position the
Telephony Modem so at least one of the screws is 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.
1Position the mounting template on the surface where you intend to mount
the Telephony Modem and secure in place with transparent tape.
2Drill holes through the template in the specified locations for the mounting
screws. After drilling holes, remove the template from the surface.
3If 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.
4Orient 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.

telephone service is not adequate. Failure to do so may result in loss of
service and/or permanent damage to the Telephony Modem.
1Connect one end of the coax cable to the cable outlet or splitter, and the
other end to the Telephony Modem’s Cable connector (E). Tighten the con-
nections by hand, then tighten an additional 1/8 turn with a wrench.
Note: For best performance, use high-quality RG-6 type coax cable and mini-
mize or eliminate splitters between the cable jack and the Telephony Modem.
2Insert the plug from the power cord into the Power connector on the Tele-
phony Modem (F) 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 Indicator Lights table for your model). See Troubleshoot-
ing if the Power light does not turn on.

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.
Check the outlet by plugging in another device (such as a lamp).
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 com-
pany 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 Modem and CATV outlet, re-
move the splitters and connect the Telephony Modem directly to the outlet.
Proceed to the Ethernet solution (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 can get on the Internet, but everything is slow.
If the Web site you are visiting is very popular, that site may be having trou-
ble 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 con-
nection 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.
To test your network speed, try an online test such as
http://reviews.cnet.com/Bandwidth_meter/7004-7254_7-0.html
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 com-
puter 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 (Tel 1 or Tel 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 Tele-
phony Modem labeled “Tel 1/2” 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 techni-
cian to correct the house wiring. If you still do not have dial tone, con-
tact your service provider.
