4 The Dilemma of Outside Plant Monitoring If you have remote sites in your network that only have a T1 connection, you probably think that installing monitoring equipment just isn t worthwhile. It can seem tough to justify the cost of monitoring at any site that has relatively little equipment, and not having LAN available doesn t make things any easier. Any solution that you might choose must include monitoring, a T1 interface, and the ability to access site devices. How can you be expected to squeeze an RTU, T1 interface, and terminal services into small outdoor cabinets? That sounds like half a rack of equipment. After considering all of this, you ve probably concluded that monitoring your small, outside plant sites just isn t economical. Achieving monitoring seems like it will require too much rack space and too much budget. But think of what you re losing by not monitoring properly. If you don t have adequate monitoring at your sites, the list of things you don t know about becomes very long: Are unauthorized intruders entering your site? Did you have a power failure? Did your HVAC fail? Are your generators low on fuel? What is the status of your equipment and gear? Learn About Remote Site Monitoring From the SNMP Experts: Attend DPS Telecom Factory Training Learn network alarm monitoring in-depth in a totally practical hands-on class. The DPS Telecom Factory Training Event will show you how to make your alarm monitoring easier and more effective.

5 Ultimately, all of these questions have a very real effect on your revenue, uptime, and client satisfaction, but there s no way to know the answers to any of them unless you have adequate visibility. If you aren t monitoring all of your sites, regardless of size or Ethernet connectivity, you will suffer through network downtime in the future. It s not a matter of if. It s merely a question of when. How many preventable outages would you have to endure before an efficient monitoring solution would pay for itself? Very often, the answer is just one. Your Big Opportunity to Extend Your WAN The value of core monitoring functionality speaks for itself, but you stand to gain even more at your T1 sites. Consider that, these days, you re getting more and more LAN-based equipment in those remote orphaned sites. If you had Ethernet connectivity, your gear would give you all kinds of useful information. But since you don t have LAN available, you can t get access to any of that information unless you physically travel to the site. For the value you re currently getting from it, your equipment might as well not even support Ethernet. From provisioning to operation to maintenance, not having LAN connectivity at your sites means plenty of unnecessary truck rolls and wasted time and expense. Here s your big opportunity: An ideal monitoring solution won t merely use the available T1 connection for transmitting alarm data. You will also be able to provide Ethernet to several devices on site. Now you have access to the data your gear was designed to transmit over LAN, including data sent as SNMP traps. Let DPS Help You Survey Your Network A Free Consultation at No Obligation to You Determining your alarm monitoring needs can be tough. If you ve got a busy job with a lot of responsibilities, you don t have a lot time to evaluate alarm systems and survey your remote sites. Rick Dodd Director of Sales DPS Telecom So why not get help from experts you can trust? DPS Telecom will help you survey your remote sites step-by step, making sure you don t miss any opportunities to make your network monitoring simpler, more effective and easier on your budget. A DPS expert consultant can help your figure out what alarm system will most effectively meet your needs without overloading your budget. Our goal is to help you maximize your return on investment while minimizing your expenditure without pressuring you to buy a particular system. There s no hard-sell sales tactics. No harassing sales calls. No pressure to buy. We won t discuss specific equipment options until we ve helped you plan the right monitoring strategy for your network. 5

6 6 Outside Plant Monitoring Options That You Should Avoid If you don t think you have any good outside plant monitoring options, you used to be right. Until very recently, you might have been able to make a decent case for not monitoring your outside plant sites. Your available options just weren t very good, being expensive, time-consuming, or both. Here are some traditional monitoring options that you should avoid: 1) Do Nothing You can always, of course, do what many people do: Nothing at all. You have the option of leaving your sites at risk, increasing the chance of a revenue-draining outage. Many people fall into this trap because it requires no additional short-term effort, but it never fails to cause them grief over the long term. Common excuses for doing nothing: It s not my job. It s not my problem. Hopefully we won t have a problem. If your network is at risk, it IS your problem. If you think avoiding proactive monitoring expense now means you won t pay later, think again. You will pay and you ll pay with interest! 2) Install Expensive Infrastructure You could theoretically install expensive infrastructure that would deliver LAN to the site, but you probably don t have the available budget. Even if you do, the ROI for that kind of large-scale installation simply isn t there. These solutions require lots of planning, people, and approvals, often dooming them to failure before they start. They re simply too big to make happen. 3) Pay Someone Else For an Internet Connection You can pay someone else to bring Internet to your locations, but that s hardly an elegant solution. Even if you use this method, you burden yourself (and your IS department) with an unknown array of security hassles. Once your data leaves your company network, you never know whose hands it might fall into. 4) Replace Your Fully-Functional Transport Equipment You could update your transport equipment to drop off LAN, but that is an expensive and very slow process. Chances are very good your current equipment isn t very old and/or not fully depreciated. In any case, it s still doing the job, and you shouldn t have to replace it. 5) Pay For Dialup Service If telephone service is available, you could conceivably monitor via-dialup, but you ll be paying monthly charges (and sometimes toll charges) for every one of your sites. Also, you ll deny yourself the benefit of extending your WAN. 6) Install Low-Speed Dedicated Circuits You could put in a dedicated circuit, but that s slow, expensive, and requires a fair amount of supporting infrastructure. Also, remember that dedicated circuits aren t going to extend your WAN either. After facing this set of depressing alternatives, it s no wonder that you probably aren t very excited about the prospect of monitoring your outside plant sites. Fortunately, a new trend in monitoring technology is set to change the way you think about monitoring in areas without LAN. 6

7 A Better Way to Monitor: The T1-Capable RTU A recent development in T1 site monitoring has made choosing between bad alternatives a thing of the past. These new additions to the monitoring landscape are T1-capable RTUs, and the good ones can do everything you need (and more) in a single, cost-effective device. Now you can see what s going on at your orphaned remote sites. By installing them at all of your T1 sites, even those that are small, you re making an important investment in mission-critical network visibility. Not only will you gain alarming, but you ll have access to your site equipment via Ethernet. When a problem occurs, you won t waste time and resources locating the source. Instead of rolling a tech for hours without really understanding the problem, you ll identify it immediately from your central office, enabling swift and purposeful action to minimize any impact to your revenue-generating uptime. In many cases, problems can be fixed before they grow into outages. A compact and versatile T1-capable remote can often pay for itself by preventing just one incident. A T1-capable RTU, such as the NetGuardian 216T, provides you with a no-brainer alternative to traditionally bad outside plant monitoring options. 7

8 8 T/Mon NOC Features that Other Masters Can t Match 1. Detailed alarm notifications in plain English that your staff will immediately understand and take action on. Every notification includes full information about the alarm, including its severity, location, date/time stamp, and a user-defined description. 2. Immediate notification of changes of state (COSs), including new alarms and alarms that have cleared. You don t have to hunt to find out what s changed in your network T/Mon lists it for you. 3. A continuously updated list of all current standing alarms. Even if the system operator acknowledges the alarm, it remains in the Standing Alarms screen until it is cleared. 4. Text message windows displaying specific instructions for the appropriate action for an alarm. System operators, even without extra training, will know precisely what to do and who to call in case of an alarm. 5. Nuisance alarm filtering. Unimportant alarms that generate meaningless status notices or oscillate between alarm and clear conditions subconsciously train your staff to ignore the alarm monitoring system. T/Mon filters out nuisance alarms, allowing your staff to focus its attention on serious threats. 6. Pager and notifications. Send alarm notifications directly to maintenance personnel, even if they re away from the NOC. 7. Derived alarms and controls that combine and correlate data from multiple alarm inputs and automatically control remote site equipment to correct complex threats. 8. Mediation of all alarms to SNMP traps sent to MOM The RTU You Need is Out There RTUs with T1 support are recent monitoring developments, but that doesn t mean that they re hard to find. Eric Storm, President of DPS Telecom, explains that his company s NetGuardian 216T was designed in direct response to client needs. We were receiving significant interest in a remote that could monitor over T1, he said. A good portion of our clients have sites where a T1 connection is very cheap, but the infrastructure for Ethernet would be very expensive. Looking at scenarios like that, and recognizing that there are probably thousands of similar cases worldwide, we handed the project over to Engineering. DPS Engineering Director Mark Carberry recalls that the design process for the NetGuardian 216T involved adding an all-new T1 interface to the company s core line of remotes. The goal was to take client-favorite features from our existing RTUs and add support for T1, he said. Our hardware design is modular, so we were able to design a new product that is founded upon proven technology. The final build supports both discrete and analog alarms, has multiple control relays, functions as a terminal server, routes Ethernet to up to 7 other devices, and, of course, reports alarms over T1. We also recognized that the 216T would typically be deployed in smaller sites, so we scaled it accordingly. It fits in a single rack unit of space, and it doesn t have excessive alarm capacity that you will pay for and probably never use. If you do happen to have a few larger sites and need more alarms, you always have the option of installing expansions to cost-effectively augment the 216T s capacity, said Carberry. We ve been really pleased with the feedback from clients, he added. The units that are currently deployed are really living up to their industrial temperature ratings. Some of them are being subjected to some pretty intense heat and handling it just fine. Clients also really seem to appreciate the convenience of the integrated hub. Their techs have been able to jack into the NetGuardian, access the company network, log their progress, and check for new assignments right from the field. The T/Mon NOC Remote Alarm Monitoring System provides total visibility of your network status and automatically notifies the right people to keep your network running.

9 Monitoring is No Longer as Hard as You Think You may have thought that extending your WAN, deploying monitoring, and implementing a series of terminal servers would be an incredible feat of engineering, logistics, and deployment, requiring lots of capital budget and more time than you will ever have. The reality is that an integrated solution, such as the NetGuardian 216T, addresses all of these issues. It allows you to, in a single-rackunit and DC-powered device, address your T1 interface (FrameRelay or PPP), discrete alarm monitoring, and analog alarm monitoring, remotely control devices via relays, perform terminal server functionality, and provide 7 all-important LAN feeds that will bring your other site elements (including your technicians laptops) into your network. Achieving visibility at sites outside of your LAN isn t as hard as you think. In fact, it s a lot easier than trying to maintain uptime without adequate monitoring and without access to revenue-generating equipment. It s All About ROI After you take time to fairly assess the high costs of not monitoring adequately, installing a high-quality monitoring device is a no-brainer. It only takes a few saved truck rolls or prevented outages for good monitoring equipment to pay for itself, resulting in an excellent ROI that will make you (and your boss) happy. Unnecessary Truck Rolls Eat Your Profits! Deploying monitoring equipment at your outside plant sites will prevent unnecessary truck rolls that eat away at your profits. Protect Your Return on Investment Make Sure Your Vendor Offers Guaranteed Results In my experience, clients who think hard about cost justification have a more important concern than just price. They want to make sure that they re not spending their company s money on a system that doesn t work as advertised. Bob Berry Chief Executive Officer DPS Telecom That s smart. You have to be careful when working with equipment vendors, especially on protocol mediation projects. Most vendors can t support all your legacy equipment, and they don t have the development capabilities to make integration work. Some vendors will charge you large NRE (non-refundable engineering) fees up front for custom work, and give no guarantee that the resulting product will meet your performance requirements. Personally, I think that s a lousy way to do business. I give all my clients a 30-day guarantee: If my product doesn t completely satisfy you, return it for a full refund. If I can t give you a solution, I don t want your money. If I m doing custom work for you, I don t expect you to pay for it until I ve proven that it works to your satisfaction. Very few vendors will make that guarantee. But you need to demand the best level of service from your vendor to ensure that your SNMP implementation is 100% successful. 9

10 Case Study: Consolidated Communications Finds the Perfect Fit Founded in 1894, Consolidated Communications is a family of companies providing advanced voice, data, and video services to both residential and business customers in Illinois and Texas. Consolidated Communications offers a wide range of services over its technologically advanced network, including local and long distance, high-speed Internet access, digital television, private line, and carrier services. Billy Young is a Central Office Engineer for Consolidated Communication s Texas operations, and he recently found himself face-toface with a tricky monitoring challenge. The Right RTU Was Hard to Find Young was searching for an RTU that would function reliably in the 110-degree Texas Billy Young Central Office Engineer Consolidated Communications heat. We wanted to monitor our cabinets, and there was nothing hardened out there that worked within our network architecture, Young said, adding We were limited on space. We only had one rack unit. And Young was looking to squeeze a lot of functionality into that one rack unit. We wanted a T1 interface with Frame Relay support. We wanted an Ethernet hub in the back, and we wanted it to be T1-fed, Young said. We wanted to have 16 scan points, some control relays and some analog relays, and we wanted it web-based. Many Vendors, Many Disappointments Young s search for a solution took him to several vendors. Some of them saw his desire for Frame Relay support as more of a nuisance than an opportunity. The response from one was, Absolutely not, recalled Young. They said PPP was their existing design and they weren t going to change it. One Potential Answer When he had trouble finding an RTU to meet the unique demands of Consolidated s network, Young knew just where to turn. I ve had a good relationship with DPS Telecom. I ve been dealing with them for years, he said. DPS Telecom s NetGuardian RTUs have been performing well at Consolidated for quite some time. They re reliable, Young said. We have about 160 deployed at this time, some have been deployed since 99, and I would say we might have a 1% failure rate. And Young recognizes the value of reliable alarm monitoring. When Mother Nature recently threatened Consolidated s network, Young s investment in monitoring equipment paid off. Hurricane Rita struck last year, and where we had NetGuardians, we were able to look at the voltage and watch it drop, he said. We were able to determine from that number when we needed to take a generator out. We could look at sites and tell, This one has more voltage than this one, so we need to move a generator here. These proved to be an invaluable tool during one of our company s biggest crises. But for this particular job, Young needed a combination of specialized features that no existing NetGuardian had. Vertical Integration for Perfect-Fit Solutions Fortunately, DPS Telecom is well equipped to design, produce, and deliver customized products. Because it controls every 10

11 part of its operations in-house, DPS is able to quickly develop perfect-fit solutions for its very satisfied clients. Billy Young witnessed the process firsthand. It all started with his call to a DPS sales engineer. After establishing the client s needs, DPS executed its time-tested new product development process. In the end, Consolidated got exactly the product they needed. A New Product, a Well Monitored Network, and a Very Satisfied Client The new product is the NetGuardian 216T, and it has already solved several of Consolidated s monitoring problems. One of our small offices is very remote, and we haven t had detailed monitoring there, said Young. But since all it took was a T1, we now have monitoring of all our environmentals and network connectivity for some very critical equipment, Young continued. It gives our technicians access to the network to check , do testing, or look up records, and it saves time on truck rolls because now we can access it remotely. When asked about his satisfaction with the final product, Young let his purchase orders do the talking. I ve taken the liberty of ordering fifty, and I intend to order additional units next year, he replied. What does that say? Throughout the development process, Young never questioned whether Consolidated would find the perfect fit. I had no doubt that whatever DPS committed to, they d do it, he recalled. And they have. Young has advice for anyone else considering a custom-engineered monitoring solution. They need to get their technical specs and contact DPS Telecom, he said. We ve had nothing but a positive experience. It took very little time, and we got the product we wanted.

12 How to Get What You Need The key to achieving your outside-plant monitoring goals is to get all of the functionality you need in a single box. Don t bother with a solution composed of several devices. That means more purchasing and a good chance that you won t have enough physical space in your rack. You will also have more user interfaces to learn, more power drain, more things that could go wrong, more points of contact for ordering, and more issues with interoperability. A single-device solution fits comfortably in you rack and budget, and it will cause you fewer headaches down the road. Watch Out for Proposals that Don t Actually Meet All of Your Needs Good T1 monitoring solutions are out there, but you do need to watch out for some common pitfalls when considering your options. Carefully examine any claim about compact size. A lot of proposals you review may advertise themselves as fitting in a single rack unit, but they actually require much more space upon closer examination. For example, an RTU might truly have a one-rack-unit chassis, but if you have to terminate to a separate patch panel, you re really going to need a lot more rack space than you thought. You might actually want a separate patch panel at your larger sites, but at a small site, you need to conserve as much physical space as possible. In those cases, you have to be sure that you can terminate directly to your device. This means more than just having amphenol connectors. You need to meaningfully connect wire-to-wire and bring alarms in. Integrated back-panel wire-wrap termination is available on the NetGuardian 216T Also, make sure you don t accept any proposals for devices that don t accept analogs. In today s monitoring environment, they are no longer a nicety, but a necessity. Monitoring temperature, humidity, battery voltages, fuel tank levels, signal strength and a range of other variables requires the versatility of analog inputs. When talking with vendors, make sure that their offerings are capable of accepting input from analog sensors, which typically are 4-20 ma outputs. Equally important, the same inputs should also be able to handle your 48 volt battery plant without any special transducers. Of course, once the alarms cross a series of warning and alarm thresholds, you need to be notified so you can take immediate action. While simple low and high thresholds are better than nothing, the best solutions have warning and alarms thresholds for both over and under directions. It s also good to ask about analog alarm scaling. When you view sensor data, you shouldn t be given a meaningless current or voltage that you ll have to manually convert to something usable. Temperature should automatically display as degrees, humidity as a percentage, etc. A good monitoring solution will allow you input a conversion factor that will automatically translate input from sensors into instantly actionable information. Finally, it s incredibly important to avoid proprietary monitoring protocols. You want a remote that can report to any standard SNMP manager. It should also be capable of routing SNMP traps issued by site equipment. 12

14 Don t Wait Until After Your Next Big Outage to Deploy Robust Monitoring If you allow your orphaned sites to remain unmonitored, it s just a matter of time before your suffer through another preventable network outage. But you don t have to accept the painful cycle of inadequate visibility and easily preventable outages. You can get the T1 interface, terminal server, and RTU you need in a single box. You won t have to install expensive infrastructure or pay other companies to give you the connectivity you need. What s more, you ll actually extend your WAN through T1 router functionality. It s no longer too expensive to monitor all of your sites. In fact, it s much more expensive in the long term if you fail to invest in revenue-protecting site visibility. This makes the question that you now face quite simple: Will you continue to leave your outside plant sites at risk now that an RTU is available that will fit in your enclosures and in your available budget? If you continue to ignore parts of your network, you ll continue to get the same results: expensive equipment damage, extended service outages, and unhappy customers. You can avoid these pitfalls by installing T1-capable remotes at your outside plant sites. DPS is Committed to Meeting Your Exact Needs DPS Telecom is an industry-leading manufacturer of customized alarm management products. Our custom engineering and agile manufacturing capabilitiees allow create custom monitoring products that meet your exact needs.
