Selecting an Installation LocationThere are a number of factors to consider when choosing a location to install yourTelephony Gateway:• Is an AC outlet available nearby? For best results, the outlet should not beswitched 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 ofsplit 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 andthe 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 locationpro vide a solid surface for secure attachment? For best results when mount-ing the Telephony Gateway on drywall, position the Telephony Gateway soat 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 enoughspace on either side to keep the vents clear? Blocking the vents may causeoverheating.• How close are your wireless devices? The Telephony Gateway wireless con-nection range is typically 100–200 feet (30m–65m). A number of factorscan affect connection range, as described below.Touchstone TG1672 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConﬁguration Usage Troubleshooting Glossary22

Factors Affecting Wireless RangeA 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 networksand 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 itto 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 amulti-story dwelling)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 cabinetsbetween the Telephony Gateway and other devices• Interference and RF noise (2.4 GHz wireless phones,microwave ovens, or other wireless networks)Touchstone TG1672 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConﬁguration Usage Troubleshooting Glossary23
