Good news everybody – order at COS has been restored and our all-around talent Spencer is back at the office!

After spending time away from us and doing something even more meaningful (being a full-time dad of three), Spencer has finally returned to the office and is ready to put his mind to and focus on how to connect the unconnected.

In order to write this piece, I’ve asked several colleagues what Spencer’s actual title is and what he’s especially good at. The answer won’t surprise those who know him but it seems from Sales to Customer Support and Business Development, he can do it all and he does it well! He might even be able to build the trenches to bury fiber conduits but I’m not sure…. 

So welcome back to the office Spencer!

How long have you been gone?

Spencer: About seven-eight months.

What’s your title?

Spencer: [Laughter] I’m not sure….*

What did you miss the most about working at COS?

Spencer: Warm coffee, the contact with our client’s and Ander’s jokes.

What are you especially looking forward to?

Spencer: Meeting new colleagues*, COFFEE!, playing padel, hearing about new customers and other COS updates.

*Like me, yey

You’ve been working at COS Systems for almost six years, what do you think we’re best at? 

Spencer: We’re not only a  great group of hard-working passionate colleagues but we also know how to have fun together when we are not working- Fika, Padel, some beers, etc.

I agree, thanks for taking the time to chat Spencer – now let’s get some coffee! 

If you want to know more about Spencer or (re)connect with him to talk about your fiber projects and needs, don’t hesitate to reach out. 



*Note: Since our interview, Spencer has been promoted to Head of Technical Sales Support, congratulations!

COS Service Zones is built to streamline the process of getting a fiber network started and managing the buildout communications. The first step is often a broadband survey, building a comprehensive map of the existing providers, available speeds and the need for better broadband in the community. In the latest release of COS Service Zones, we’ve launched several improvements for the survey portion of the platform.

While there is flexibility to modify and add to the built-in survey questions in COS Service Zones, the standard questions are geared towards asking the most crucial and concise questions. Yet, as with all surveys some people never finish them. The reason might not have anything to do with the survey length, they may have gotten distracted for some reasons or another. In our latest survey release, we split the survey into different steps which will capture survey data throughout. After the customer has searched for their address, next would be their email address, then thereafter we take them through the survey step by step while continuously saving data. This will enable you to later analyze at which step the survey taker drops off. Perhaps it was at the point where proposed services and prices were shown? Can it be an indication that the assortment is not what customers were looking for? Or that the prices are too high?

The other benefit of partially saving the data and requesting the email address early is the follow-up automation we’ve been able to build. COS Service Zones has a template-based email engine built into the platform, it can be used to automate personalized follow-up emails. For the customer that did not complete the survey but did share their email address, the system can now automatically send out an email to that person asking them to complete the incomplete survey, and again emphasize the importance of the data to move forward with the broadband plans. The email will include the link which will take them exactly to the step in the survey where they dropped off previously, they can just complete the last steps instead of starting over. If the person still doesn’t take the survey, another email with a slightly different message will go out after a few additional days. Everything to maximize the number of completed surveys. These emails are also an excellent way to try to figure out why those reluctant to finish the survey feel that way. By simply asking why, they could reply to the system generated email and let you know what issue they had.

Another important set of data collected in the COS Service Zones survey phase is the customer’s current internet speed, by asking them to initiate a speed test. To ensure that the data is as accurate as possible, the survey will first confirm if they are using the connection that they would replace with a new fiber connection. If the answer is NO, then the speed test will not show up at the end of the survey, as that would corrupt the data. Often those who are not using their home connection are at some public place like the library or at work, where they typically have faster speeds than their home service. We’ve also added automation to maximize the number and the accuracy of the speed test results received. For those who took the survey and never completed the speed test from their home connection, an automated reminder email will be sent out. And those who indicated that they were not using their home connection and later never completed a speed test, another email will be sent explaining that once they are using the connection that they would be interested in replacing, they can follow the link in the email that will take them to their mypages, where they can start the speed test. The result of the speed test will automatically be mapped to their submitted survey. This process will also fetch the IP address, which determines the current home connection provider, thus a map of the competitive landscape can be understood.

These are just some of the new features that are now live with the latest system upgrade. Don’t hesitate to reach out to us if you would like a walkthrough of everything COS Service Zones helps you with in the initial phases of your fiber project and throughout the buildout or expansion!

A small budget, long distances and low population density surely does not sound like the best prerequisites for a fiber network buildout. By working in a structured, but still creative way and with a good dialogue with the local community it is still feasible. It has been proven over the last six years since Kitsap PUD started to work with COS to build demand for and operate their Open Access fiber network.

To understand how this success story began, we must jump back all the way to 2003. As members of NoaNet (Northwest Open Access Network), another customer of COS, Kitsap Public Utility District (KPUD) got access to the fiber backbone that was built throughout the rural parts of Washington State. In 2003 KPUD started building a middle mile network, branching off from the NoaNet fiber ring and connected their first community anchor tenants; schools, libraries, navy facilities, but also a number of businesses. Being a water utility and not having the big budgets as some of the electric utilities in Washington State have, it was a slow but steady buildout that generated a small, but positive cash flow. An excellent starting point for any community wishing to initiate a fiber project as not only costs can be lowered to the anchor institutes, but that the revenue from those fiber connections will also stay local.

Over the coming years, the incumbent telecom companies didn’t improve their presence in the county much and not only businesses, but also residents started to ask if KPUD could expand their fiber network to reach them, as some other PUD’s in the state had done. KPUD decided to find a way to determine if there was a big interest for this and that is when they started working with COS Service Zones. Within just a few days from launching the site, the response was overwhelming with over 2000 completed surveys. The lack of high speed and quality broadband in the county was clear.

KPUD is running their network on an Open Access model and is operating it using COS Business Engine. This means they are not themselves providing the retail services but invite private sector providers to do so. Already from the start several Service providers saw the benefit of being able to reach new customers without any investments in infrastructure, even though the numbers were initially small.

So, without a big budget how were they able to expand their networks in these rural areas? The secret recipe is called LUD:s (Local Utility Districts). While the middle mile network is expanded by a mix of cash flow revenue, tax dollars and grants, the last mile connections to the homes are paid by the homeowners, but it is not a one-by-one thing. Instead, in neighborhoods or areas where KPUD has identified a high demand with COS Service Zones the total cost for the buildout is calculated and the cost per household is determined. Residents will decide if they want to participate or not and high participation obviously leads to a lower cost. Residents have the option to pay upfront, but many choose to spread the cost out over time through one of the partnerships KPUD has established with local banks that will allow a long term loan with a fixed interest rate and a lean on the property. Even if these costs can in some less densely populated areas be quite substantial, people are willing to sign up knowing it will not only provide a better internet service, but also increase their property value. Just recently the very last homeowner who didn’t opt-in initially in one of the first LUD’s decided to connect – effectively a 100% take-rate in that neighborhood, even though the last mile connection has to be paid by the homeowner. Another rural COS Open Access customer, neighboring Mason PUD3, is also using a model where customers can pay off their installation over time with a $25 monthly construction adder to the cost of their service for 12 years.

Angela Bennink, Telecom Director at KPUD, explains that the Open Access model is a big proponent of the network and the choice it offers make people more willing to sign up and connect. Subscribers know that the competition between multiple providers will ensure a good quality of service and reasonable prices. And switching between providers is made extremely easy by the self-service broadband Marketplace provided with the COS Business Engine operations platform.

“Our biggest challenge now is keeping up with demand,” says Bennink.

Especially during this Covid-19 pandemic the need for broadband has been extreme. The proximity to Seattle, across the water also makes the population grow at a rapid pace. 100 000 new residents are expected in the coming three years and KPUD is working with developers to make sure they put in conduit for fibers as they build.

“We have slowly and steadily grown and we will add close to 500 new customers this year and as many next year. We have found a model that really works with our prerequisites and the functionality to streamline the capture of interest and the operations of our Open Access network provided by COS System’s platforms has been a part of that success,” says Bennink.

“It’s been an absolute honor to have been part of KPUD’s journey from the first survey responses coming in, to the successful growth they are showing today. They have proved that with a strong localized strategy and perseverance rural fiber is possible,” says Isak Finer, Chief Revenue Manager at COS Systems.

Partnership to optimize network construction in line with customer demand and priority service zones, capitalizing on forecasted ~$100B near-term investment in network infrastructure.

Denver, Colo. – January 28, 2021 – Communication Service Providers (CSP) across North America and global markets will now be able to harness real-time, geospatial data to streamline customer sign-up to connection experience and significantly reduce network build-out duration.

Today COS Systems, provider of market-leading software platforms COS Business Engine and demand aggregation platform COS Service Zones, announced a partnership with Render Networks (Render), an innovative Digital Network Construction platform, to optimize the end-to-end delivery of fiber and wireless networks.

With escalating consumer expectations for connectivity and the forecasted $100B near-term investment in network infrastructure, optimal delivery is critical. The industry is looking to efficiencies and ‘best-of-breed’ technologies to accelerate broadband accessibility. This newly formed digital alliance and fully-integrated approach break through traditional network rollout constraints with proven demand, deployment, and network services management technology.

Together, COS and Render enable CSPs to quantify demand, build dynamically in response to evolving priorities, and – with real-time geospatial insights – dramatically improve deployment durations and connection experiences.

The COS software suite provides a customer and revenue-focused approach to network rollouts. COS Service Zones covers everything from initial broadband surveying to driving demand with pre-sign ups that inform deployment priorities. COS Business Engine provides customer-centric delivery of services, from the initial installation of equipment to a self-service marketplace that supports True Open Access Network, increasing customer choice while maximizing network utilization and revenue.

Render’s Digital Network Construction platform converts network designs to sequenced tasks for field crews and enables construction teams to build based on optimal build scenarios without manual, paper-based processes. Accurate as-built data is progressively collected and readily integrated into downstream systems, including COS Business Engine.

“With skyrocketing demand for connectivity and bandwidth, our industry is looking for solutions to rapidly deliver network infrastructure. Previous regulatory and funding constraints have subsided, and it’s incumbent on us to collaborate and seamlessly integrate to enable CSPs to achieve their network objectives.

At COS Systems, we’ve spent more than a decade automating traditional network processes. By integrating with Render, the industry has a highly automated network deployment and operations solution generating significant efficiencies for fiber and wireless projects.” said Isak Finer, CMO & VP North America at COS Systems.

“Given the pace at which the industry needs to deliver these networks, the ability to dynamically build for the greatest potential return has never been more important or achievable with the integration of our respective innovations,”

“Customer expectations are rising, and a digital-first demand to delivery approach can achieve significantly faster network ROI. We’re thrilled to partner with the team at COS Systems to accelerate the delivery of critical communications infrastructure at a time when it’s needed most.” said Sam Pratt, CEO for Render Networks

Both organizations are founding members of the Digital Network Alliance; best-in-class technology innovators with a shared mission to make available an integrated, end-to-end digital value chain for communications infrastructure planning, delivery, and operations.

Sep 22nd – Exhibit Hall Virtual Marketplace Presentation on COS Service Zones and the New Speedtest Release

Sep 24th  – Build Your Network as an Open and Automated Platform for Future Providers, Services and Revenue – Fast internet is just one of a multitude of services that can be delivered on your fiber infrastructure. By building your network from the start with the ability to virtually slice every fiber for specific services and for specific providers – while also being able to price those slices separately – it will be possible to deliver all the services of the future on one shared infrastructure. Yes, this introduces a whole new level of complexity. And, yes, automation is crucial. But it is already being done today, and we’ll show you how!

Sep 24th – Workshop: Zero Touch Provisioning of True Open Access Networks  – COS Systems has been automating service provisioning on fiber networks in Europe since 2008. In this workshop you will get to experience how this works and meet the engineers who made it possible. COS Systems is now introducing this functionality in North America in partnership with Nokia and you will also learn about their end-to-end electronics platform and architecture strategies for automated networks open to multiple service providers.

If you are interested in reading up on how we can automate the provisioning of services you should check out page 76-78 in the march/april edition of the BCC Magazine. There is also a piece about it on the news section of our website. 

Brownsville, TX, has been on the list of the least connected US cities for the past few years. Oldham County is only a short drive from Kentucky’s largest city Louisville but does not have adequate access to broadband. Through a partnership with Lit Communities, COS Systems is part of the solution for both of these cities.

Lit Communities are helping municipalities build a plan for improved broadband access, as well as offering support in financing, constructing and operating networks. With the firm determination that it’s always feasible to find ways to deploy a future proof broadband infrastructure in every community, each project starts with an in-depth assessment of the unique conditions of the specific market. The result is a business case that outlines how a sustainable network can be built and operated.

Even though this kind of business case is incredibly complex to produce, it builds on getting answers to two questions that are simple to ask; What will it cost to build and operate the network, and what will the revenue be?

It is on the revenue side of the business case preparation that COS Service Zones comes into play. While the cost is calculated by producing network designs based on service locations to be connected and existing assets in the form of fiber, conduit, poles, etc. the revenue side is harder to estimate. It is determined by how many subscribers will sign up and what services they will buy. This is why Lit Communities are using COS Service Zones to perform what is known in the industry as Demand Aggregation.

Two recent projects where COS Service Zones have been launched are in Brownsville, TX and Oldham County, KY. Both of these projects are in the first phase of demand aggregation where residents and businesses are encouraged to go to their localized COS Service Zones sites to show their interest by taking a survey. In this survey they will be asked questions about their current service and provider, as well as indicating what service package they would be interested in and their likeliness to sign up. The survey also asks market specific questions to gather information valuable to building the plan for that community. After answering the short questionnaire, the respondents will also be asked to complete a speed test that will give them what download and upload speeds they are receiving from their current provider. The results will give a good picture of what speeds are available, where customers have access to high speeds already and which incumbent providers can provide proper broadband speeds. One particularly interesting question to answer is how many respondents actually reach the definition of broadband, which today is set at 25 Mbps download and 3Mbps upload – A definition most can agree is far too low with everything the internet is used for today.

By integrating to social media and allowing local residents to sign up as “Champions”, the COS Service Zones platform aims to build a grassroots word-of-mouth movement, where the local community will drive as many people as possible to show their interest. In most communities this works incredibly well, with hundreds and even thousands of survey responses in a just a few days. This is especially true in communities currently unserved or underserved, or where incumbent providers have used their monopoly position to keep the prices high and network upgrades to a minimum – unfortunately, something common in smaller cities and rural areas.

With access to this real-time data, captured from the same persons who would be the subscribers on the network, Lit Communities can accurately predict future take-rates and revenue. The data will also help to determine what service offerings and pricing would be optimal for ensuring high take-rates and network sustainability. With these results, it takes the guesswork out of play and creates an accurate business case for the municipality and investors.

Despite the value the survey produces, the major strengths of the comprehensive COS Service Zones platform are still to come into the play when the decision to move the project forward from planning to execution is taken. Now, knowing exactly where in the city demand is greatest and competition weakest, based on the survey responses, service zones –“fiberhoods”- can be created. These are neighborhoods that will have their own signup page where the number of households required to get on the construction list is highlighted. It is now up to the neighbors to come together and sign up. The best neighborhoods will be prioritized in the build-out, ensuring that the financials of the project are always intact, and that revenue can be optimized.

“With a dedication to close the digital divide for everyone, a vision we at COS share, Lit Communities’ ultimate goal is always to deploy a complete fiber based network to every home and business in the community and then operate it on a True Open Access model, allowing local as well as external service providers to offer services to the residents and business on their networks. It will offer local companies the opportunity to grow and an attractive assortment of services and providers to the subscribers. We hope and believe that this will become a reality in Brownsville and Oldham County, “says Isak Finer, CMO and VP North America at COS Systems.

Every year the leading fiber broadband publication Broadband Communities Magazine lists the Top 100 companies in the Fiber To The Home Industry in the United States. For the 8th year straight COS Systems earns a place on the list for its innovative software solutions allowing fiber builders to capture demand for fiber and operate True Open Access Networks with world-leading efficiency.

As the FTTH market continues to grow in the USA, COS System’s solutions are becoming increasingly important. Today, compared to eight years ago when COS first earned a position on the prestigious list, more types of entities are entering the fiber industry. While eight years ago mostly the incumbent carriers and some private ISPs were making efforts to deploy fiber networks, today many of the buildouts are driven by communities, utilities and coops.

The COS Service Zones platform, playing a vital role in any fiber deployment is used to survey communities about their need for better broadband as well as allowing the fiber builder to pre-sign up customers. By dividing the planned build-out area into smaller “fiberhoods” and letting them compete to reach signup take-rate targets, the fiber builder will know where demand is sufficient for initiating the build-out. While this helps any kind of entity reduce the risk of a build-out by signing customers up beforehand, COS Systems other solutions are very well suited to meet demands of the new entrants to the market.

As community focused entities are planning to build out fiber networks they tend to have an infrastructure view, in contrast to traditional service providers who focus largely on the services. For a municipality the biggest interest is rather what community benefits a fiber infrastructure would bring in the form of quality of life for residents and competitiveness of their businesses. With COS Business Engine, the BSS/OSS platform developed specifically for streamlining operations of True Open Access networks, COS Systems shares this infrastructure view of fiber. While the community can focus on finding ways to get the fiber infrastructure deployed, choosing an Open Access model allows them to partner with private service providers for bringing services to the

“We are happy to be on the list for yet another year and with the market development we are seeing I am certain we will be on the list next year as well! As municipalities are stepping up and taking lead in the efforts to get their communities connected, the interest in Open Access networks is increasing rapidly. This will especially benefit rural America since they will be able to attract service providers who would otherwise not be able to offer services due to constraining deployment costs. If communities can find ways to get the infrastructure in place, Open Access and the market forces within the private sector will take care of the rest. We’ll be there to make sure there are systems supporting both the demand based incremental build-out as well as the efficient operations of a network with multiple competing service providers”, says Isak Finer, CMO and VP North America at COS Systems.
