Ethernet Connection to One Computer
Make the connections to the modem in the following sequence:
1.
Connect one end of the coaxial cable to the cable connection in the wall, and the other end to
the CABLE jack on the Residential Voice Gateway.
2.
Connect the plug from the AC power supply into the POWER AC ADAPTER jack on the
Residential Voice Gateway, and plug the power supply into an AC outlet.
Note: Use only the power supply that accompanied this unit. Using other adapters may damage
the unit.
3.
Connect one end of the Ethernet cable (straight-wired, see below) to the Ethernet port on the
back of your computer, and the other end to the ETHERNET port on the Residential Voice
Gateway.
Make sure that the Ethernet cable is straight-wired (not “null” or crossover-wired). However,
you will need a crossover-type cable if you are connecting the modem to a hub, or a hub
within a port switch that provides the same function.

Connecting More Than Two Computers to the Residential Voice Gateway
For TWG 850, if you need to connect more than two computers or if you need to connect two
computers, but USB is not available, you’ll need the following additional equipment:
²
Crossover-wired, or “null,” category 5 Ethernet cable for the EMTA Gateway to be connected
to the hub
²
10BaseT or 100BaseT Hub or Switch
²
Straight through, or standard, category 5 Ethernet cable (one for each computer to be
connected)
If you have a hub with an uplink port*, a straight through cable can be used in combination with
that port in lieu of the crossover cable.
*An uplink port has a small switch on it to change the polarity of the connection. It can accept
either a crossover or a straight cable, depending on the setting.

Telephone or Fax Connection
When properly connected, most telephony devices can be used with the Residential Voice
Gateway
just as with conventional telephone service. To make a normal telephone call, pick up
the handset; listen for a dial tone, then dial the desired number. For services such as call waiting,
use the hook switch (or FLASH button) to change calls. The following procedures describe some
of the possible connection schemes for using telephony devices with the Residential Voice
Gateway.
1.
Connect a standard phone line cord directly from the phone (fax machine, answering
machine, caller ID box, etc.) to one of the LINE jacks on the
Residential Voice Gateway.
2.
If there is a phone line in your home which is NOT connected to another telephone service
provider, connect a standard phone line cord from a jack on this line to one of the LINE jacks
of the Residential Voice Gateway. Connect a standard phone line cord directly from the phone
(fax machine, answering machine, caller ID box, etc.) to one of the other jacks in the house
that uses that line.
3.
If you have a multi-line telephone, connect a standard phone line cord (not an RJ-14 type line
cord) from the phone to the LINE jacks on the Residential Voice Gateway. (Other phones can
be added to each line by using standard phone line splitters.
