About this Manual
This manual covers all of the different TM822 models. Your model may not have all
of the capabilities outlined in this manual. To determine which model you have pur-
chased, refer to the image at the left. The model number is on the label affixed to
the Telephony Modem.
Ethernet Connection
Ethernet is a standard method of connecting two or more devices into a Local Area
Network (LAN). Use the Ethernet connection if your computer has built-in Ethernet
hardware or you want to share the Telephony Modem connection with several com-
puters. Arris recommends using an Ethernet connection.
Note
:
To connect two or more computers to the Ethernet port, you will need a
hub or broadband router (available at computer retailers).
The Telephony Modem package comes with a 6-foot (1.9m) 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 Modem
directly to a computer, or to an Ethernet hub or broadband router with a cross-over
switch, ask for Category 5e (CAT5e) straight-through cable. CAT5e cable is required
for gigabit Ethernet (Gig-E), not regular CAT5 cable.
