TM
ST-261
for DOCSIS Problem Solving in HFC Networks
provides complete analysis of DOCSIS network performance from
Cable Modem and CMTS Modulation Error Ratio
(MER)
to IP data.
The ST-261聮s advanced demodulation technology enables system
operators to quickly identify and resolve DOCSIS problems whether
they are due to RF or data-related impairments
T
he ST-261 is the only DOCSIS Protocol Analyzer available. It
