Twenty years ago if you wanted to monitor a site you would use a RTU to collect the alarms. Over time transport equipment manufacturers began to improve the internal monitoring of their equipment, but they also started exposing alarm points that would allow users to bring in critical and major alarms from other devices in the site.
The basic premise was that you could add an "alarm card" to the transport and bring back the alarms to the same management platform that was monitoring the transport/switching equipment.
Over the last 6 years communications companies have been thinking twice about pursuing these "embedded" solutions in favor of independent external alarm collection devices. Here are the 8 reasons why:
Telecom is a specialized industry. OEM's are very good at their core competency, but alarming isn't their key focus. It is however the focus of DPS Telecom. The embedded solutions typically don't have functions like alarm qualification, alpha paging, local visibility and web browser interfaces. The proactive OEM's have realized this and rather than re-invent the wheel have integrated alarm remotes like the NetGuardian 832A into their designs.
This means that you either can't monitor everything you want to see, or have to "OR" so many alarms together, you don't know exactly what failed.
This means that those sites don't get monitored, or they have to be monitored in a non-standard way. Or you might find you have several different generations of embedded monitoring solutions, all with different capacities so you can't come up with a common standard.
This means that you can't independently monitor any "value" that you are interested (i.e.: inside temp, outside temp, battery voltage, signal levels, etc).
Controls allow you to remotely flip a relay to control some other device (i.e.: Reset a piece of equipment, open a door, start a generator, turn on a light).
As More Telecommunications Companies Evolve More Sophisticated Network Operations Centers that monitor a multitude of different devices, it makes more sense for the alarms to report directly to the NOC in a common open protocol like SNMP. The ability of DPS RTU's to support multiple masters addresses today's need for comprehensive disaster recovery plans.
Perhaps one of the more interesting reasons why embedded solutions are no longer in the best interest of a telecommunications company is because of the trends that are taking place in the industry and the underlying business models. Let's take a look at the Cellular industry. Competition is more fierce than ever. Clients are demanding more bandwidth and features. How do companies address this? They buy new equipment to differentiate themselves. While great for the provider's customers, it creates a multitude of problems/cost centers for the service provider. This is not a one time change, but a continuous repeating cycle.
Embedded solutions typically communicate using integrated signaling or some other overhead area. The upside of this is it is "Free", but the risk is that if you lose the site, you lose your telemetry so you don't have the complete picture of what is going on at the site and why. By using out of band communications path (not part of the system), you will be far less likely to lose visibility.
By deploying an external RTU, you address everything discussed. Not only will you get better site visibility on multiple fronts, you'll save lots of money by deploying alarm equipment once instead of every time your fundamental technology changes
