VoIP
The VoIP (additional purchase required) tests the voice quality of your
VoIP networks, gateway, internet protocol (IP) phones, and other end-
point devices.
After the meter has successfully ranged and registered with the Cable
Modem Termination System (CMTS), the PacketCable multimedia
terminal interfaces, and the Multimedia Terminal Adapter (MTA) has
been successfully initialized, you are provided the ability to place and
receive a phone call with the meter. After a call is placed or received,
test results are displayed.
NOTE
VoIP test can only be initiated after the DSAM has successfully reg-
istered with the CMTS, and the MTA has successfully initialized.
If “Ranging Only” is the selected configuration option, VoIP mode
does not initiate.
A call cannot be placed or received if registration with the CMTS
has failed.
NOTE
If more than one VoIP DOCSIS channel is discovered in a down-
stream channel plan, the meter prompts you to select a DOCSIS
channel. Use the up and down arrow keys to highlight a DOCSIS
channel then press the ENTER key or the Start softkey.
