Split and corrected cable pairs that are in short distances may never cause others-on-line complaints in plain old telephone service (POTS circuits), but will raise havoc on higher bandwidth services such as ADSL, HDSL, T1 and IPTV, especially when vectoring for higher speed.
I have been using field test sets for over 45 years. Demands on paired copper cable, and the business need to quickly and efficiently solve problems, has led to the development of growing complexity and sophistication in test sets.
In my April 2012 column I wrote of 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 worked with a smart, dedicated telephone technician to solve this difficult problem.
Noise mitigation, bonding and grounding, and electrical protection is absolutely critical for quality bandwidth over the copper infrastructure. I again turn to the sage advice from Russ Gundrum, my Inductive Coordination Electrical Protection Engineer guru.
I have been in the telephone business for more than 48 years in one manner or another, working with telephone companies or equipment providers around the world. Some Telcos, both large and small, have made it; and some Telcos, both large and small, have failed. Why did some companies make it while others with same opportunity failed? It's a delicate balance….
Following is an example of a job I worked on recently that required an accurate locate, and although this job is specific to a type of conduit, the process to make any metallic conductor locatable is universal.
After I wrote an initial article on B&G several months ago, I've had tremendous response from several experts. In this column, I provide feedback from another expert: Mr. Allen Gara, Engineering and Operations Manager for LEA Networks, LLC.
A large percentage of circuit failures occur in terminals and pedestals in the distribution plant. The most significant cause of these failures is the lack of proactive maintenance. When a company is not doing proactive maintenance the operating costs to maintain customer service goes up exponentially while system reliability drops like a rock.
The issue of bonding and grounding is critical to effective outside plant, and particularly when broadband or Triple Play is implemented. My two-part column on this topic drew many, many responses, so thank you to all of you readers and to those who responded.
