Reserve Your Seat TodayDo you have some sites that are completely unmonitored because you don't have LAN? Having visibility over your remote sites is necessary to protect you from unanticipated failures.
Still, getting LAN to a remote site can be costly and sometimes even geographically impossible. Expensive LAN transport cards don't provide any monitoring at all, and they can even cost many times more than an RTU.
What's really effective is to deploy a remote telemetry unit (RTU) like the NetGuardian 216T from DPS Telecom, it supplies LAN to your devices using your site's T1 or E1 connection, while simultaneously handling monitoring, control, and alarm reporting. That's typically less expensive than a LAN card from your transport manufacturer, and the RTU will simultaneously perform monitoring and control functions and include a network switch.
If you understand and like the concept of T1-based RTUs for your network, you might want to jump directly to some actual equipment:
T1 RTUs (Remote Terminal Units with a built-in T1 Interface) change the game of monitoring your outside-plant (OSP) sites. Unlike traditional LAN RTUs, WAN RTUs can be deployed directly at sites that don't have LAN. Once you do that, you'll instantly have monitoring at your remote sites.
"Remote monitoring" of course includes the simple things like monitoring contact closures for basic event monitoring. But choosing the right T1 RTU means you can also deliver LAN to external equipment with the RTU's on-board network switch.
In this dual-pronged way, T1 RTUs extend your monitoring. You get WAN-based alarm monitoring of traditional contact closures. Latching relays tell your T1 RTU that an alarm has occurred, and that's transmitted back to your master station via T1. You also get site monitoring: LAN access to your equipments' proprietary interfaces (software or web browser).
Here's a diagrammed example of a real T1 RTU application:

Deploying the NetGuardian 216T at each of your outside-plant remote sites is a cost-effective way to get Frame Relay/T1 monitoring without juggling multiple vendors or devices. DPS Telecom builds it as a single unit: monitoring, T1 routing, and a terminal server in one box. If you've been struggling with unworkable quotes involving FRADs and Ethernet-only solutions, a Frame Relay/T1 RTU could be the answer.
You get monitoring, T1 routing and a terminal server in single box. You won't have to buy multiple units, deal with multiple vendors, or struggle with multiple tech support numbers. You can gain crucial Remote Alarm Monitoring and Control visibility in areas covered only by your Frame Relay Network, and you can do it on limited budget.
As this application drawing illustrates, you don't need point-to-point access devices with a Frame Relay/T1 RTU. You get everything in just one box. T1 event monitoring is a practical solution for remote sites that don't have LAN. The NetGuardian 216T from DPS Telecom is purpose-built for exactly this, giving you alarm visibility, analog monitoring, and LAN delivery over your existing T1 infrastructure. Fewer truck rolls, less guesswork, more control over your network.
