server for these tests.
Level - This is the amplitude level of the upstream signal set by
the ranging process with CMTS in dBmV.
Block Error Rate (BkER) - The BkER is the upstream bit error
rate measurement. BkER is the ratio of errors that occur in the
upstream transmission path compared to the total amount of data
sent. 1.0 E-3 is marginal performance, while 1.0 E-4 or better is
expected.
Test Information
The test information section contains data about the Cable
Modem connection and Registration process.
Ranging Frequency - The center frequency of the downstream
DOCSIS QAM signal.
File - The file name of the configuration file sent to the cable
modem.
IP Address - The IP address assigned to the integrated cable
modem in the DHCP process.
Emulator IP Address - The second routable IP address assigned
to the Install Profiler that demonstrates an acceptable IP
connection was established.
Gateway IP Address - The gateway established during the
registration process, typically the IP address of the CMTS.
MAC Address - The MAC address of the internal cable modem.
QAM Search - Pass/Fail – Indicating whether the cable modem
was able to lock on the downstream signal.
Ranging Level - Pass / Fail – Indicating whether the internal
cable modem was able to complete the ranging process.
Ranging DHCP - Pass / Fail – Indicating whether the internal
cable modem was able to get an IP address from the DHCP
server.
Ranging TOD - Pass / Fail – Indicating whether the internal
