Provides DOCSIS, Ethernet, CM Diagnostics page, and VoIP measurement
modes that view and analyze CATV channels.
DOCSIS
DOCSIS measurement mode analyzes the digital performance of a user-selected
DOCSIS channel to verify downstream/upstream connectivity. Only DOCSIS
channels defined in the downstream (forward path) channel plan are available
for DOCSIS measurement testing. DOCSIS tests include:
Ranging
Analyzes and displays measurement performance data on the upstream and
downstream signal level, downstream modulation error ratio (MER) (or EVM,
as configured), and the estimated downstream bit error rate (BER) before
and after forward error correction (FEC). The ranging measurement data
can be viewed in relation to user-configured limits to determine the Pass/Fail
status of the DOCSIS channel.
Registration
Analyzes and displays internet protocol (IP) addresses of the dynamic host
configuration protocol (DHCP), trivial file transfer protocol (TFTP),
time of day (TOD) servers, and the gateway. The registration test also
provides the modem's internet protocol (IP) address, configuration file,
and Service IDentifier (SID).
Throughput
Displays throughput (upstream and downstream) test results. (See the Help
section entitled "Interpreting Throughput Results".)
Packet Loss
Displays packet loss (round trip, upstream, and downstream), and upstream
signal to noise ratio (SNR) test results. (See the Help section entitled
"Interpreting Packet Loss Results".)
Ping
Analyzes and displays the overall downstream/upstream communication route
and connectivity of a DSAM within the cable system. The ping test is a
continuous test that allows you to select the IP address, packet size,
and time between pings and displays ping test result data that includes;
round trip time, time-to-live (TTL), percentage of loss of data, and average
round trip time.
VoIPCheck (Optional Purchase Required)
VoIPCheck provides an CMTS Loop test and Segmentation test. ) This feature
does not require MTA provisioning. The VoIPCheck test is a continuous
test that provide packetloss, jitter, delay, R-Value and MOS values.
ETHERNET (Optional Purchase Required)
Analyzes the internet protocol (IP) performance through the Ethernet.
CM DIAGNOSTICS PAGE (Optional Purchase Required)
Displays a cable modem's internal web page.
VoIP (Optional Purchase Required)
Provides the ability to measure voice quality of your VoIP networks and
gateway, internet protocol (IP) phones and other end point devices.
