Yes, convergence is a great idea and, increasingly, customers will be served by wireless and fiber to the home. However, despite predictions that FTTH was imminent, for some time to come copper that is well maintained will serve countless customers while Telcos are moving ever so gradually to the wireless fiber world.
In January, I was invited to consult on a continuing DSL HSI outage on the West Coast. It was one of those crazy "Is it a power problem?" or "Is it a cable problem?" scenarios with lots of finger pointing. Meanwhile, the customers were up in arms.
I received an email from Percy E Pool, P.E. (retired protection engineer) commenting on my December 2011 column, Are You Really Ready for The Triple Play? Percy had concern on the validity of my statements on bonding and grounding at the Network Interface. Please see last month's column, February 2012, for the first part of my response. Following is Part Two.
My area of expertise is the copper infrastructure and dirty power in the residence. When a field technician is dispatched, the root causes are many and all too often the field technician works on the effect of the problem and not the root cause. Below I have listed some of the big hitters that affect bandwidth.
For those of you in Triple Play, I don't have to tell you about the problems that can be caused by dirty power. It's something that comes up in my classes and keeps my phone ringing when I'm not training. One of the most frequent questions is about noise from electric fences
Back in March of 1990, I ran a test for field technicians in OSP magazine. There are many new techs out there and many new technologies so I’m going to run it again. This is a test for the new technician in the Triple Play business using that Last Mile of copper.
Noise Mitigation is one of the many tasks a quality cable maintenance technician will occasionally encounter. Sadly, few techs receive any training on noise mitigation and yet related problem can cause expensive troubleshooting and repair and involve long hours. But there is good news….
For those few companies who maintained copper over the many years, they can provide Triple Play. For those who haven't invested in ongoing proactive maintenance, you have years and years and years of wearing down your cable and, unlike PSTN, if you don't fix it right, it simply won't support Triple Play.
