Chapter 2
Preparing for Installation
Site Requirements
Each service provider has its own recommendations and requirements for the CPE devices
connected to its network. However, at the very minimum a PC should meet the requirements listed
in Table 2-1.
•
Ensure that you bring sufficient cables to connect all devices at all subscriber locations. For
simultaneous TV and computer usage at a subscriber site, obtain cable splitters and directional
couplers as appropriate to install when you install the cable voice adapter.
•
The Cisco CVA122/CVA122E Cable Voice Adapter automatically obtains its IP address from the
headend DHCP server at power-up. Typically, the PCs at the subscriber site are also configured to
use DHCP to obtain their IP addresses; if this is not the case, obtain the static IP addresses for each
PC from the applicable system administrator, along with the appropriate gateway and DNS
information.
•
If supporting VoIP devices, obtain the phone numbers and/or IP addresses that the service provider
has assigned to each of the voice ports on the Cisco CVA122/CVA122E Cable Voice Adapter.
