Step 5 The Message LED should stopblinking, and the Cable StatusLED should turn on solid within
ten minutes after connecting the Cisco CVA122/122E Cable Voice Adapter to the cable TV
wall outlet. If the Cable Status LED does not come on solid after ten minutes, check that the
coaxial cable is properly plugged into the correct cable TV outlet and in to the cable voice
adapter’s Cable TV In connector.
Connecting to Telephones, Modems, or Fax Devices (optional)
If you have purchased voice services from your service provider, use the following procedure to
connect the Cisco CVA122/122E Cable Voice Adapter to telephone, modem, or fax devices. If you
have not purchased voice services, skip to the “Connecting to the Computer (Ethernet, optional)”
section on page 11.
Step 1 Obtain the telephone number assignments for each voice port from your service provider,and
label each telephone, modem, or fax device with its assigned number.
Step 2 Connect the RJ-11 end of this cable to the appropriate voice port (labeled “V1+V2” or “V2”)
on the rear panel of the Cisco CVA122/122E Cable VoiceAdapter. Press the cable firmlyinto
the receptacle.
Step 3 Connect the other end of the cable to the telephone, modem, or fax device that has been given
the number assigned for that voice port. Press the cable firmly into the receptacle.

Note The V1+V2 connector supportseither a single-line ora 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.
Step 4 Repeat Steps 2 and 3 as needed to connect another telephone device to the other voice port.
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
