Remote Monitoring System for a Telephone Company in the Middle East

DPS Telecom designed a monitoring solution to specially attend the necessities of a telephone company in the Middle East. This particular company needed to monitor 20 different sites and the best-suited RTU for that was the NetGuardian M16 G2.

16 out of 20 sites are using the Netguardian M16

The first part of this this system will be applied for 16 out of the 20 sites. It will start with a generator sending contact closures into a 66 Block. Those contact closures can alert some issues, such as problems with the oil pressure and overheating. There is also two smoke detectors working with this 66 Block. The information about those alarms travel through an Amphenol Cable until the NetGuardian M16.

This Netguardian M16 runs on AC power. It will originally run on -48V, +24 or +12V DC. If specified, a wall transformer can be included to your purchase order so it will be able to run AC.

Also, the system designed for this company includes 2 D-Wire Temp/Humidity probes. Note that since the D-Wire is tiny all it needs is a RJ12 cable to be connected to the NetGuardian. This cable powers the D-Wire as well so there is no need for any other supply of energy. These probes count as 4 D-wire sensors: 2 in each box and each box having both temperature and humidity configurations.

Now looking at the other 4 sites. Since they have a smaller capacity requirement the TempDefender G2 was selected. This device has half of the capacity of the NetGuardian M16.

Since 4 sites needed this device, then 4 TempDefenders were included in the system.


The capacity of this device is:

  • 8 discrete alarms
  • 6 analog channels, used for all sorts of sensor inputs or voltages
  • 3 control relay outputs, they make it possible to reach out and make adjustments from the central office
  • 4 D-Wire ports

The TempDefender also includes a DC input for when a wall transformer is necessary.

The T/Mon Mini G2 is the smallest T/Mon model available

All the 20 different sites are tracked via LAN and polled by a T/Mon Mini G2. This is the smallest T/Mon model available, supporting just 16 devices. With an expansion module it can support up to 32 devices.

In this particular monitoring system, the expansion was necessary to support all the 20 sites. The company still has room for 12 other devices if it decides on future expansions under this T/Mon. This will require no further upgrading.

The T/Mon polls each NetGuardian in sequence; this will happen every several seconds so any problem will be quickly detected.

The T/Mon has a couple of different ways to alert you about issues. They are:

Ways that the T/Mon can send you alerts


  • Web GFX: This web interface is where image backgrounds, like maps or diagrams, can be set with icons on top of them. On the example for this company, there will be a map where circles are going to start blinking on a certain color if something is wrong. The icons then will show a picture of what is going on. It is even possible to get a photograph of the site itself to help technicians that will go inside the hut and get inside the racks of equipment.
  • Email or SMS: You can get a notification from the T/Mon via email that can als obe translated into a text notification. This tool is really useful to help people that happen to be out of the office, improving the efficiency of the team.
  • Data base administration over LAN: The T/Mon has a web interface for configuration where everything can be set up.
  • Web browser support featuring web 3.0: Allows you to do several applications, such as generate reports and export them as a PDF file


The T/Mon is a powerful tool, not only when polling in NetGuardians and TempDefenders, both made by DPS Telecom, but it can also support 35 or more protocols.

It is important to always make sure that all the systems are compatible while under the same monitoring umbrella. The T/Mon is the perfect device for that because it has the flexibility to check the status of alarms from different types of equipment.
