ST-261
Portable DOCSISTM Protocol Analyzer
for DOCSIS Problem Solving in HFC Networks
The 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-261Âs 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
