Protocol Analyzer
for DOCSIS Problem Solving in HFC Networks
T
he ST-261 is the only DOCSIS Protocol Analyzer available. It
provides complete analysis of DOCSIS network performance from
Cable Modem and CMTS Modulation Error Ratio (MER) to IP data.
The ST-261s advanced demodulation technology enables system
operators to quickly identify and resolve DOCSIS problems whether
they are due to RF or data-related impairments
APPLICATIONS
Resolving complex DOCSIS
related problems
Identify modems with poor
MER performance
Resolve DHCP and TFTP
server errors
Resolve BPI/BPI+ registration
issues
Analyze VoIP applications
Detect DOCSIS violations
and inter-vendor conflicts
Test security risks at RF
Trigger and log network
events to disk for analysis
Remotely monitor specific
cable modems and CMTSs
