System Requirements

The Touchstone Telephony Gateway operates with most computers. The following

describes requirements for each operating system; see the documentation for your

system for details on enabling and conﬁguring networking.

To use the Telephony Gateway, you need DOCSIS high-speed Internet service from

your cable company. Telephone service requires that the cable company has Pack-

etCable support.

Recommended Hardware

The following hardware conﬁguration is recommended. Computers not meeting this

conﬁguration can still work with the TG1662, but may not be able to make maxi-

mum use of TG1662 throughput.

•

CPU: P4, 3GHz or faster

•

RAM: 1GB or greater

•

Hard drive: 7200 RPM or faster

•

Ethernet: Gig-E (1000BaseT)

Windows

Windows XP , Windows Vista, Windows 7 or Windows 8. A supported Ethernet or

wireless LAN connection must be available.

MacOS

System 7.5 to MacOS 9.2 (Open Transport recommended) or MacOS X. A supported

Ethernet or wireless LAN connection must be available.

Linux/other Unix

Hardware drivers, TCP/IP, and DHCP must be enabled in the kernel. A supported

Ethernet or wireless LAN connection must be available.

About this Manual

This manual covers the Touchstone TG1662 Telephony Gateway. The model num-

ber is on the label afﬁxed to the Telephony Gateway. See the image at the left.

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 Gateway.

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

ca b

le company may suspend your account to protect the rest of the net-

work.

•

The TG1662 ships with wireless LAN security set by default (for the same

reasons that you should run only secured proxies). See the security label on

your product (shown on image at the left) for the factory security settings.

If you need to modify the default wireless security settings, see

Ethernet or Wireless?

There are two ways to connect your computer (or other equipment) to the Tele-

phony Gateway. 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). You can use the Ethernet connection if your computer has

built-in Ethernet hardware.

Note

:

To connect more than four computers to the TG1662 through the Ether-

net ports, you need an Ethernet hub (available at computer retail ers).

The Telephony Gateway package comes with one 4-foot (1.2m) 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 Gateway di-

rectly to a computer, or to an Ethernet hub with a cross-over switch, ask for Cate-

gory 5e (CAT5e) straight-through cable. CAT5e cable is required for gigabit Ethernet

(Gig-E), not regular CAT5 cable.

Wireless

Wireless access lets you connect additional (wireless-capable) devices to Telephony

Gateway. The 802.11 wireless LAN standard allows one or more computers to ac-

cess the TG1662 using a wireless (radio) signal. These connections are in addition

to the connections supported via Ethernet.

Note

:

You can use the wireless connection if your computer has a built-in or af-

termarket wireless card. To learn more about which wireless hardware

works best with your com puter, see your computer dealer.

Both

If you have two or more computers, you can use Ethernet for up to four devices and

wireless for the others. To connect ﬁve or more computers to the Ethernet ports,

you will need an Ethernet hub (available at computer retailers.)

Battery Installation and Removal

The TG1662 Telephony Gateway supports a Lithium-Ion backup battery to provide

continued telephone service during power outages. The battery backup is not in-

tended to take the place of AC power.

The backup battery provides up to 12 hours of backup time, depending on model

and usage. It has a strap between the battery guides.

Your cable company may include a backup battery with your Telephony Gateway.

You can order batteries at http://yourbroadbandstore.com/

Note:

For safety and regulatory purposes, batteries are shipped outside of the

Telephony Gateway and must be installed.

Battery Installation and Replacement

Use this procedure to install or replace the backup battery.

1

Press down and pull back on the latch holding the battery door (on the bot-

tom of the Telephony Gateway). Pull the door toward you. Set the door aside

in a safe place.

CAUTION

Risk of equipment damage

Improperly inserting the battery may damage the battery connector in

the Telephony Gateway. Carefully follow the instructions in the next

step to avoid damage.

2

Hold the battery pack so that the guides on the battery align with the slots

on the Telephony Gateway and slide the battery into the bay. The diagram

on the left shows the proper orientation.

Note

: Batteries will not insert completely into the Telephony Gateway if not

oriented correctly. The battery should slide into the bay without signiﬁcant

force. Line up the slots in the battery bay with the guides on the battery

and apply even pressure on both ends of the battery.

3

Push the battery pack into the bay until it latches into place.

If you are

taking the battery out of the Telephony Gateway, use the battery

pull strap to dislodge the battery.

Note

: The Telephony Gateway will not begin operating until you apply AC

power.
