DOCSIS Security Illegal Wiretapping and Eavesdropping

2012-09-04T10:00:57-04:00September 4th, 2012|

Wiretapping has Evolved Before electronic eavesdropping there was just wiretapping.  When you think of wiretapping you may think of a guy in a box truck or apartment eating donuts with pizza listening in on endlessly boring phone conversations waiting to hear that one "Eureka" moment of important information.  The movie Casino comes to mind too.  The scene where Sam and Nicky have their wives talk on the phone first and then take the conversation over in timed intervals so that they can speak. So what is wiretapping?  It is

Subscribers get lower data rates than provisioned?

2020-06-09T09:36:58-04:00July 5th, 2012|

Why do my DOCSIS subscribers and their Cable Modems get lower speeds than what my DOCSIS config file says they should get? This is a common question that I am asked and it has more than one answer.  All too often the RF plant is the first to blame for low DOCSIS cable modem speeds, but in many cases the root cause of the problem can be traced back to the cable modem configuration file and/or the lack of appropriate speed test applications in the headend.  Also, some
