Cisco CVA122 Quick Start User Manual page 11

Note The V1+V2 connector supports either a single-line or a two-line analog telephone that
uses a four-wire connection. If using a two-line telephone, the second line behaves as if it
were a single-line telephone plugged into the V2 voice port; you can then plug a second
device in to the V2 port and use it as an extension to the second line telephone.
Repeat Steps 2 and 3 as needed to connect another telephone device to the other voice port.
Step 4
Caution Do not plug the Cisco CVA122/122E Cable Voice Adapter into any RJ-11 jack in
your home, unless otherwise instructed by your service provider. The cable voice adapter
must not be plugged in to the Public Telephone Switched Network (PTSN) or in to any jack
that is connected to the PTSN; doing so will damage the cable voice adapter.
Connecting to the Computer (Ethernet, optional)
These steps connect the Ethernet port on the Cisco CVA122/122E Cable Voice Adapter to a computer
using an Ethernet network adapter card. This is required only when you are using the Ethernet port
to connect the cable voice adapter to a computer; if you are using the USB port, see the next section.
Note Do not proceed with these steps if your computer does not have a working Ethernet
interface. If necessary, install an Ethernet network adapter card according to the
manufacturer's instructions before proceeding.
Step 1 Plug one end of the supplied straight-through Ethernet cable to the RJ-45 connector labeled
Ethernet on the rear panel of the Cisco CVA122/122E Cable Voice Adapter.
Step 2 Plug the other end of the Ethernet cable into the RJ-45 connector on your computer's Ethernet
network adapter.
Step 3 Verify that the Ethernet Status LED on the front panel of the Cisco CVA122/122E Cable Voice
Adapter is on. If this LED does not come on, check that the Ethernet cable is plugged into the
correct RJ-45 connector on your computer and that the computer is turned on. Also verify
that the other end of the cable is plugged into the Ethernet connector on the
Cisco CVA122/122E Cable Voice Adapter.
If the steps above do not correct the problem, check that the Ethernet adapter is configured for TCP/IP
operation, as described in the "Configuring the Computer for Ethernet Network Access" section on
page 22.
