Most of us are still stuck in some form of a hybrid cross between SDI and the networks now being designed. Karl's best advise here, is to be
sure and get a good System Integrator to assemble and build your new plant. They will pay attention to such details as making sure that every component of your plant is properly configured, and that such information
is entered into a book given to you when they are finished. Make sure you continue its accuracy by creating a log of events pertaining to any changes or maintenance performed on any part of your plant from that
point on. Call it a book of knowledge, a log, or what ever you like, but make it a rule that whomever does any work on your facility enters into it what and when it was done. It helps if you have to revert to the
previous configuration to get back into a working state. Karl says when networks become troubled he has found trying to marry new and old switches together often can cause problems, simply because they don't adhere
to the same protocols. He also has found that what was designated as the "Grand Master" clock can become overwhelmed when having to constantly respond to component timing responses.
As networks grow, the Grand Master needs to hand those type of responses off to Boundary Clock units. These can be added as necessary to handle
added components on your network. Make sure each Grand Master has its own GPS network, and put some space between each of those, reducing the chance of wind damage eliminating the GPS signal to both units. Yes, you
need two independent networks for redundancy, and a seamless switch between them. Each part of a distributed network must have its own Grand Master. No one said this was going to be cheap. Which brings up another
point. You should present your need for test gear to management as a business case. Managers often have accounting backgrounds, and test gear should be presented to them as an item that saves them downtime, added
personnel, and therefore money. The question came up as to what Prism (ST 2110 Network Analyzer) range of cost might be? Karl said that at present, $12 - $38K should be planned in your budget, depending on how many
bells and whistles you need. It is mostly in already in the software, so it usually is a matter of buying whatever you need and entering the correct license key to obtain access to the next level of testing.

Our program ended and we stood adjourned at 8:20 PM, on motion of John Langer, seconded by Ron Jones. This was an
excellent presentation, with plenty of time allowed for interaction for those with questions. Our thanks to Karl Kuhn and to
Telestream for the presentation. His card is included with other supporters of SBE-3, on page 5, if you wish to contact him. I
hope all of you enjoyed the holidays to the fullest, although things were, as one of my neighbors put it, "strange, this year". Many
family traditions were postponed, or new ones invented because of the CoVid-19 pandemic.Some families met via Zoom for their
Christmas meal, while others limited the size of the gatherings considerably or met with one part of the family at a time to limit
the size. Our family followed the latter choice. My wife found it difficult to cook Christmas dinner for so few, so she packed up a
plate for our neighbor who wasn't able to go out of state to visit his daughter this year, and though we didn't eat together, we were
able to share our Christmas meal in that way. However all that may be, we can all be hopeful the vaccines can put an end to the
CoVid, and life can get back to something resembling normal. or an acceptable substitute.
Have you considered SBE Member- Plus as an option? From January 1, 2018, individuals have been able to choose to join or
renew as a Regular, Senior or Associate member (based on eligibility) at the traditional low-cost rate of $85, and purchase any
SBE online education program a la carte. SBE MemberPlus has all the benefits of Regular SBE membership and includes
access to all the live and archived Webinars by SBE in the SBE catalog plus any new webinars the SBE adds during the
membership year, but at a higher cost. You get free access to the extensive SBE webinar education resource, which is an
enormous benefit, For less than the cost of two Webinars by SBE, the member who opts for SBE MemberPlus will have access
to all the online education programs that cover a wide range of technical broadcast and media topics, for one year. So what
brought this up? January 21, SBE will host a new Webinar: #1 in a series on Networking. If you have been thinking about
Certification in Networking, here is an excellent place to start. Yes, as an SBE Regular Member, you can watch this Webinar for
$62. But, for $85, less than the cost of two Webinars, you get access for a year to any or all of the recorded Webinars SBE has
done. Give it some thought, You could be on your way to SBE Network, or another SBE Certification!
A 6½" snow on New Year's Day made me glad I had the foresight to run the snowblower through the shop for a long overdue tune
up. It started on the first pull, and an half hour later, our driveway was clean, with the remnants melting in the early afternoon
sunshine. The snow blower's carburetor float valve had been stuck open with old gas goo, making it easy to flood the engine and
hard to start. Now, I use non-ethanol in all my gas engines for tools. When you are done with the job at hand, either empty the
unused gas back in the supply container or install a cut off valve so you can run the carburetors dry. It costs a bit more, but my
chain saws have survived many years with this practice, and they are always ready to go when next called on for use. 30.
Chapter 3 Zoom Meeting Attendees November 17, 2020

The basis of the new network has to be Precision Timing Protocol for all parties involved in handling any part of a program. That too
would have to be included in the program data flow from origination to final product. Without that, you would never get all the pieces recombined in any order that made sense. Our order of stable
fixed timing is no longer a given. Now, configuration of all components currently, or in the future on a network, becomes very important, because each one must be synced with, and adjusted
for the proper delay in a dynamic way. Besides configuration, even the cleanliness of fiber connections becomes of paramount importance. There are no patch panels to assist with trouble
shooting, and we are left with having to develop new network analyzer tools that can inspect dataflows before and after any piece along the network. Karl recommends immersing yourself in
not only PTP, but knowing by heart the standards set out in ST2110 and later publications covering the new networks being developed. There are very few of us that have had the
opportunity to design and build a new all digital facility.
