Power Monitoring Is Your Best Defense Against Invisible Site Failures

By Andrew Erickson

November 7, 2025

Share: 

When the power goes out at a remote telecom site, it's tempting to view it as a short-term inconvenience.

The lights go off, so you assume battery backup kicks in and you wait. Then the power comes back, so you move on.

This may seem "simple", but it actually involves a lot of risk.

For telecom professionals and network operators, the real damage of a power outage often happens after power is restored. Without effective power monitoring, you're left exposed to silent failures, unseen damage, and hidden costs that add up quickly - and keep adding up.

You Can't Protect What You Can't See

If your remote sites aren't fully monitored, you don't know what you don't know!

You can't tell if your HVAC has failed and your equipment is baking inside a hut. You can't tell if a generator failed to start due to a dead starter battery. You don't know if your backup batteries are dangerously close to total discharge.

The worst part is you won't know you're in trouble until it's already too late.

Power Outages Have Hidden Costs

Sure, you already know that downtime is expensive. But what really happens when the lights go out at your site? And why are so many network operators shocked when they see the actual costs?

Five ways power outages cause unexpected damage include:

1. Thermal Shutdown from Failed Air Conditioning

Your routers, radios, and switching gear may have DC battery backup power, but do your HVAC units?

Most operators forget this. They assume that, if the network gear itself is up, everything's fine.

But when the A/C stops, heat begins to rise inside your site. Equipment might continue running for a while - until it reaches a thermal threshold and shuts itself down to prevent irreversible damage.

What's worse is: once the environment heats up, you can't restart your gear until the temperature returns to safe operating levels. That means longer recovery times, reduced uptime, and lost revenue even after commercial power is restored.

2. Permanent Battery Damage from Deep Discharge

Most people neglect the fact that telecom batteries aren't designed to run until they're completely drained. Doing that - even once - can reduce their lifespan significantly or destroy them outright.

And it's not just discharge. It's also heat.

If your batteries are subjected to high temperatures - such as, over 122 F - you can take a 10-year-rated lead-acid battery and burn it out in barely over a year.

Multiply that damage across dozens or even hundreds of sites, and you're looking at tens of thousands in avoidable replacement costs.

3. More Windshield Time, More Truck Rolls, More Lost Money

If you're sending techs out to sites just to check battery levels, inspect generators, or press reset buttons, you're wasting money. Every truck roll costs you time and labor. Every mile driven adds up in expenses.

Worse, most of these visits could be avoided entirely if you had the ability to monitor and control equipment remotely. Unmonitored systems mean sending someone on-site "just in case."

Proper power monitoring means knowing when something is wrong - and dispatching only when absolutely necessary.

4. Total Loss of Remote Visibility

When the RTU at your remote site goes dark during a power failure, you lose more than just a signal. You lose total visibility.

That includes:

  • Backup power system status
  • Environmental conditions (temperature, humidity, fire, water)
  • Site security and intrusion alarms
  • Equipment alarms from routers, switches, and more
  • Terminal server data
  • Remote control capabilities (like starting a generator)

Losing power without visibility is like flying a plane with no instruments through a storm. You might survive it - but you'll never feel safe doing it.

5. The True Financial Cost: It's Not Just About Equipment

When you add it all up, a power failure affects your bottom line in four critical ways:

  1. Lost revenue from outages and service disruptions
  2. Repair costs for damaged gear
  3. Replacement costs for equipment beyond repair
  4. Labor costs for restoring service

It's not just about a few blinking lights. It's about how power failures affect your revenue, reputation, and resource allocation. And it's 100% preventable with the right monitoring gear.

Utilize Power Monitoring That Sees What You Can't

The good news is you don't have to accept these risks. With a solid power monitoring plan, you can protect your remote sites, reduce expenses, and take control of your network - even during an outage.

At DPS Telecom, we've spent more than 30 years building gear that helps network operators maintain visibility and control when it matters most.

NetGuardian G6: Remote Monitoring Evolved

We've evolved to the new G6 NetGuardian RTU series - a line of next-gen monitoring devices that gives you faster processing, stronger security, and future-ready performance.

With a G6 NetGuardian RTU at your site, you can:

  • Monitor battery voltage and get alerts when it drops
  • Control generators remotely with output relays
  • Trigger alerts for under-voltage, AC loss, or generator failure
  • Log into a secure web interface from anywhere
  • Support SNMPv3 for encrypted alarm reporting
  • Add sensors for temperature, humidity, or door status

And thanks to our "general-purpose" design philosophy, these remotes are not tied to any specific manufacturer. They speak open protocols and integrate with a wide variety of gear.

If you're still using older units or proprietary systems, it's time to upgrade.

Advantages of G6 platform

T/Mon LNX Provides Total Network Visibility from One Screen

Pair your G6 RTUs with the T/Mon LNX alarm master, and you get real-time visibility of your entire network - hundreds of sites, thousands of alarms, one screen.

T/Mon does more than just show you alarms. It gives you control.

With it, you can:

  • Set up derived alarms like "Low Battery AND No Generator"
  • Schedule generator self-tests and get alerts only if they fail
  • Consolidate alarms from SNMP, MODBUS, ASCII, and legacy protocols
  • Assign user permissions by role or region
  • Receive alarms by email, SMS, or voice dial-out

This isn't a closed ecosystem. You can integrate third-party SNMP devices into T/Mon right alongside your DPS RTUs.

What Monitoring Looks Like During a Power Failure

When you're equipped with a DPS monitoring system during a power failure, the gear adapts to address the needs of your network. The process typically follows a few steps:

  1. Commercial power fails.
    Your G6 NetGuardian detects the loss and automatically switches to battery. You receive an alert instantly.
  2. Battery voltage starts to drop.
    The G6 tracks the voltage in real time. You're notified if it crosses your custom threshold.
  3. Generator fails to start.
    Since your start battery is drained, the generator can't kick in. You're notified immediately, so you can dispatch a tech with the right part in hand.
  4. Temperature rises inside the hut.
    The HVAC is out, so the G6 sends environmental alarms. This allows you to prioritize the site before shutdown.
  5. You log into T/Mon.
    You get a complete picture of your network. You can even activate outputs remotely to start backup equipment or transfer load.
  6. Power returns.
    You review event logs, confirm everything's back to normal, and store the report for compliance and future planning.

DPS Is a Proven Partner for You

Most remote monitoring vendors build products as a side project. It's just one of their many offerings.

DPS Telecom is different. Remote monitoring and control is all we do (aside from some "stretch" projects from clients who fall in love with our customization ability).

From the first T/Mon in the 90s to today's G6 RTUs, we've continuously improved our gear based on real customer feedback.

That means:

  • Durable hardware built to survive harsh environments
  • Firmware upgrades to meet new requirements (often at no cost)
  • Custom tweaks to meet your unique needs
  • Lifetime support that doesn't expire after a 1-year warranty

If you want to reduce truck rolls, protect your equipment, and eliminate outage guesswork, we're here to help you build a power monitoring strategy that works.

Ready to Talk? Here's What to Do Next

No setup is perfect. Maybe you've had surprise battery failures. Maybe you've sent techs on preventable truck rolls. Maybe you've had enough downtime to realize: you need visibility.
