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

Factors Affecting Wireless Range
A number of factors can affect the usable range for wireless connections.
Increases range:
Decreases range:
•
Raising the unit above the devices (for example, installing the Telephony Gateway in the upper floor of a
multi-story dwelling)
•
Adding wireless hubs in a bridge (WDS) network
•
Lowering the unit below the devices (for example, installing the 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)
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 trasmit power level to High increases the range. Setting it
to Medium or Low decreases the range proportionately.

Mounting the Telephony Gateway
You can either mount the Telephony Gateway on a wall or place it on a desktop.
For wall-mount applications, you can mount the Telephony Gateway with the indicators facing upward (vertical) or to the side (horizontal).
Tools and Materials
Step 1
Step 3
Step 2
Step 4
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 (not included)
•
screwdriver (flat-blade or Phillips, depending on what kind of screws you
use)
•
wall-mount template (included)
•
transparent tape: for temporarily securing the mounting template to the wall
(not included)
Location
Always position the Telephony Gateway:
•
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).
Instructions
Wall-mounting instructions
Note:
When mounting the Telephony Gateway on drywall, try to position the
Telephony Gateway so at least one of the screws is fastened to a stud.
This may prevent the Telephony Gateway from pulling out of the wall in
the future. To prevent overheating of the Telephony Gateway, do not
block the ventilation holes on the sides of the unit.

Position the mounting template on the surface where you intend to mount
the Telephony Gateway and secure in place with transparent tape.
Drill holes through the template in the specified locations for the mounting
screws. After drilling holes, remove the template from the surface.
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.
Orient the Telephony Gateway with the indicator lights facing up or right, as
desired. Slip both mounting slots (in the back of the Telephony Gateway)
over the screws, then slide the case down until the narrow end of the keyhole slot contacts the screw shaft.
Proceed to Connecting the Telephony Gateway.
Desktop mounting instructions
Position the Telephony Gateway so that:
•
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 side of the unit are not blocked.
Proceed to Connecting the Telephony Gateway.

Connecting the Telephony Gateway
WARNING
Risk of injury or equipment damage
Connecting the Telephony Gateway 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 voltage. Cancellation of
telephone service is not adequate. Failure to do so may result in loss of
service and/or permanent damage to the Telephony Gateway.
B C
Connect one end of the coax cable to the cable outlet or splitter, and the
other end to the Telephony Gateway’s Cable connector (G). 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 Gateway.

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?
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 (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 (next page) if necessary.

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 Gateway router.
If you think this has happened, see Resetting the Router to Factory Defaults.
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 your connection.

I don’t have dial tone when I pick up my 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.
Is the Power LED lit?
•
If not, check to make sure the Telephony Gateway 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 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.
Is the Telephone (Tele 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.
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 “Telephone 1/2” for line 1, and “Telephone 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 Gateway plugged into a wall outlet?
•
If so, unplug the RJ-11 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.

The following is a list of common cable and networking terms.
Amp-hour (Ah)
A measure of battery capacity. For example, a 1.0Ah battery can nominally
supply one Ampere of current for one hour.
Category 5 (Cat5)
A high-quality type of cable, used for Fast Ethernet (100BaseT) connections.
When purchasing Ethernet cables, always look for Category 5 cable.
Coaxial cable (coax)
A thin wire, used to connect your television and Telephony Gateway to the
cable TV system. You can buy coax from any electronics retailer and many
discount stores.
CPE
Customer Premise Equipment. This is the equipment that is plugged in to the
Telephony Gateway; typically a computer or hub.
Cross-over
An Ethernet cable used to connect two hubs (or a hub and a cable modem)
together. Also, some Ethernet hubs may have built-in cross-over on one or
more ports (which eliminates the need for a cross-over cable).
DHCP
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.
DNS
Domain Name Service (Server). An IP service that associates a domain
name (such as www.example.com) with an IP address.

Downstream
In an HFC network, the direction from the head-end to the subscriber. Some
older cable documentation may refer to this as the forward path.
DOCSIS
Data Over Cable System Interface Specification. The interoperability standards used for data communications equipment on an HFC network.
EMTA
Embedded Multimedia Terminal Adapter. An MTA device that is integrated
with a cable modem.
Ethernet
A standard method of connecting two or more computers into a Local Area
Network (LAN).
EuroDOCSIS
The European version of DOCSIS.
Event
An informational message used for monitoring network status.
F-connector
The type of connector used on coax cable. There are two common types of
F-connector, slip-on and screw-on. Use coax with screw-on connectors for
connecting your Telephony Gateway.
Firewall
A hardware or software device that prevents unauthorized access to a private network from the Internet. The TG852 provides a built-in firewall.
Gateway
The device, usually a router, that connects devices on a given IP subnet to
other IP subnets.

Headend
The “central office” in an HFC network. The headend houses both video and
data equipment. In larger cable networks, a “master” headend often feeds
several “remote” headends to provide distributed services.
HTTP
HyperText Transfer Protocol.
Hub
A box with several Ethernet connectors. Ethernet hubs provide a common
point of contact for all connected devices.
IP address
A number assigned to your computer by your cable company, used to identify your computer to other systems on the Internet.
ISDN
Integrated Services Digital Network. A digital telephony standard that provides communication speeds about twice as fast as standard dialup.
LAN

Proxy
A device or program that stands in between a server (for example, a web
site) and a client (your browser), providing a way to relieve some of the
burden from the server. For example, your cable company may have a web
proxy that keeps copies of popular web pages; the proxy can send you those
pages instead of fetching them directly from the web site, resulting in faster
page loading and less network congestion.
RF
Abbreviation for Radio Frequency. Some literature refers to coax as “RF
cable” and the connectors as “RF connectors.”
RJ-11
A standard 2-conductor modular connector, commonly used in North America for connecting telephones.
RJ-45
A standard 8-conductor modular connector, commonly used on Ethernet
cable. An RJ-45 connector looks like a wide RJ-11 (telephone) connector.
