ARSVD01310 Release 8 Standard 1.1 May 2010 Safety Requirements ARRIS Telephony Gateways comply with the applicable requirements for perform- ance, construction, labeling, and information when used as outlined below: CAUTION Risk of shock Mains voltages inside this unit. No user serviceable parts inside. Refer service to qualified personnel only! CAUTION Potential equipment damage Potential loss of service Connecting the Telephony Gateway 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 Gateway. CAUTION Risk of explosion Replacing the battery with an incorrect type, heating a battery above 75°C, or incinerating a battery, can cause product failure and a risk of fire or battery explosion. Dispose of used batteries according to the instructions. • The Telephony Gateway is designed to be connected directly to a telephone. • Connecting the Telephony Gateway to the home’s existing tele phone wiring should only be performed by a professional in staller. • Do not use product near water (i.e. wet basement, bathtub, sink or near a swimming pool, etc.), to avoid risk of electrocu tion. Touchstone TG852 Telephony Gateway User’s Guide Safety Getting Started Battery Installation Installation Ethernet Configuration UsageTroubleshootingGlossary 3 • Do not use spray cleaners or aerosols on the Telephony Gateway. • Avoid using and/or connecting the equipment during an electri cal storm, to avoid risk of electrocution. • Do not use the telephone to report a gas leak in the vicinity of the leak. • Do not locate the equipment within 6 feet (1.9 m) of a flame or ignition source (i.e. heat registers, space heaters, fireplaces, etc.). • Use only power supply and power cord included with the equip ment. • 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 in- stallation codes. In the U.S., this is required by NFPA 70 (National Electrical Code) Article 820. In the European Union and in certain other countries, CATV instal lation equipotential bonding requirements are specified in IEC 60728-11, Cable networks for television signals, sound signals and interac- tive services, Part 11: Safety. This equipment is in tended 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, as is found in many areas of Norway, spe cial attention should be given that the installation is in accor dance 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 Conver sion) on the AC, RF, Ethernet and Phone lines. • When the Telephony Gateway is connected to a local computer through Eth- ernet cables, the computer must be proper ly grounded to the building/res- idence AC ground network. All plug-in cards within the computer must be properly installed and grounded to the computer frame per the manufac- turer’s specifications.

E Telephone 2: connector for the second phone line. F Ethernet (1 - 4): connectors for use with a computer LAN port. G Cable: connector for the coaxial cable. H Power: connector for the power cord. 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 exten- sion cords are not required. • Is a cable jack available? For best performance, keep the number of split- ters between the jack and cable drop to a minimum. Each splitter attenuates (re duces) the signal available to the Telephony Gateway. A large number of split ters can slow down the Internet connection and even affect your tele- phone 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 ca- bles between the Telephony Gateway’s location and those devices? • If you want to mount the Telephony Gateway on a wall, does the location pro vide a solid surface for secure attachment? For best results when mount- ing 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 Tele- phony 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 con- nection range is typically 100–200 feet (30m–65m). A number of factors can affect connection range, as described below. Touchstone TG852 Telephony Gateway User’s Guide Safety Getting Started Battery Installation Installation Ethernet Configuration UsageTroubleshootingGlossary 20 Factors Affecting Wireless Range A number of factors can affect the usable range for wireless connections. Note:Note that decreasing the range of your wireless network may be bene- ficial, as long as the decreased range is sufficient for your needs. By lim- iting your network’s range, you reduce interference with other networks and make it harder for unwant ed users to find and connect to your net- work. Note:Setting the trasmit power level to High increases the range. Setting it to Medium or Low decreases the range proportionately. Increases range:• Raising the unit above the devices (for example, in- stalling the Telephony Gateway in the upper floor of a multi-story dwelling) • Adding wireless hubs in a bridge (WDS) network Decreases range:• Lowering the unit below the devices (for example, in- stalling the Telephony Gateway in a basement) • Metal or concrete walls between the Telephony Gate- way 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) Touchstone TG852 Telephony Gateway User’s Guide Safety Getting Started Battery Installation Installation Ethernet Configuration UsageTroubleshootingGlossary 21 Step 1 Step 2 Step 3 Step 4 22 Safety Getting Started Battery Installation Installation Ethernet Configuration UsageTroubleshootingGlossary Touchstone TG852 Telephony Gateway User’s Guide 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 indi- cators facing upward (vertical) or to the side (horizontal). Tools and Materials For wall-mounted installations, make sure you have the following tools and mate- rials 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. …
