Whether you're new to our equipment or you've used it for years, DPS factory training is the best way to get more from your monitoring.
Reserve Your Seat TodayMost networks aren't built from a single vendor's equipment. They're built over years, across different budgets, using whatever worked at the time. The result is a mix of devices speaking SNMP, Modbus, DNP3, TL1, ASCII, and protocols you half-forgot existed.
A multiprotocol alarm monitoring system solves this. Instead of logging into a dozen separate interfaces to check site status, you get one centralized view covering everything, regardless of manufacturer or protocol.

A multiprotocol alarm monitor is a central system, often called an alarm master station, that collects alarm data from remote equipment using multiple different protocols simultaneously. It translates those inputs into a unified display so your team can manage all alarms from one place.
Without this, your options are limited: log into each device individually, run parallel monitoring tools for each protocol, or simply leave older equipment unmonitored. None of those options scale.
If you're managing fewer than about 10 sites, the built-in alerting on your RTUs (email notifications, relay outputs) can work as a lightweight substitute for a centralized master. Once you grow past that, managing alerts site by site becomes unwieldy. You start missing alarms, losing context across locations, and spending more time logging into individual devices than actually resolving problems.
At that point, you need a dedicated alarm master station, whether or not you have multiple protocols on your network.
Where multiprotocol support becomes essential is when your network includes a mix of communication protocols. That's common in networks built over time, where older and newer equipment coexist:
A large SNMP-only network still benefits from a high-quality alarm master for centralization, escalation, and reporting. But once you add equipment that speaks different protocols, a single-protocol SNMP manager can't reach everything, and that's where T/Mon's multiprotocol support fills the gap.
DPS Telecom's T/Mon alarm master station currently supports 30+ protocols. The most common include:
| Protocol | Common Use Case |
|---|---|
| SNMP v1, v2c, v3 | Network infrastructure, routers, switches, modern RTUs |
| Modbus | Generators, rectifiers, industrial site equipment |
| DNP3 | Utilities, SCADA environments, IEDs |
| TL1 | Legacy telecom equipment |
| ASCII/Text | Devices outputting raw status messages |
| DCP | DPS-native protocol for T/Mon-to-NetGuardian communication |
| 25+ additional protocols | See the full list of T/Mon supported modules |
If your equipment uses a protocol not on this list, contact us. T/Mon's protocol library has grown to 30+ specifically because clients needed integrations that didn't exist yet. We're willing to develop support for new protocols when it serves a real deployment need.
T/Mon functions as your network's single collection point. RTUs and remote equipment at your sites report to T/Mon over Ethernet, serial, T1, fiber, GSM/CDMA, or dialup. T/Mon translates each protocol into a unified alarm display. Any alarm originating from any protocol can trigger any display/alert within T/Mon, regardless of its source.
Key capabilities:
"We can now use the ASCII processor on the T/Mon to Telnet into our devices to find out the root cause of a problem and report that directly to the alarm screen. This will allow our operators to get critical information much faster because they won't have to open the Telnet and issue the queries to get more detail. This shortens the time to dispatch, which is good for everybody." - Tim LaChance, National Grid
"The biggest feature improvements I've seen are auto-databasing ASCII and auto-databasing SNMP. For a lot of our alarms, we haven't been able to get them onto the screen. Now we can do that with those functions." - Joel Beecher, National Grid
T/Mon is designed to work alongside, not replace, enterprise management platforms already in use. If your organization uses a large-scale SNMP manager for its core network, T/Mon can sit alongside it, handling the protocols that platform can't reach while forwarding normalized alarm data upstream. Learn more about T/Mon remote monitoring and management.
Our NetGuardian RTUs support SNMP reporting to any third-party master, so they can feed data into your existing tools while also reporting to T/Mon for multiprotocol consolidation.

An SNMP manager collects data only from devices that speak SNMP. An alarm master station like T/Mon handles SNMP plus many other protocols, including DNP3, Modbus, TL1, and ASCII. If your network is entirely SNMP-based, either may work. If you have mixed-protocol equipment, you need a multiprotocol master.
T/Mon scales from small deployments monitoring a handful of sites up to enterprise installations overseeing thousands of locations. The modular architecture is designed so your investment grows with your network.
Yes. TL1 and ASCII support are specifically maintained for backward compatibility with older telecom equipment. DPS has worked with clients whose networks span devices from multiple decades, and T/Mon is built to handle that mix. If you have a new requirement T/Mon doesn't yet support, that's commonly when we'll bundle custom engineering into your purchase. Most T/Mon purchases can include customization without an NRE fee.
Yes. T/Mon's 30+ protocol library exists because clients brought integration needs that required new development. If you have a device using a protocol T/Mon doesn't currently support, contact our engineering team to discuss options.
T/Mon collects data from remote equipment over Ethernet, serial, fiber, T1, GSM/CDMA, and dialup, covering virtually any connectivity scenario including remote or rural sites with limited infrastructure.
DPS Telecom has been building multiprotocol alarm monitoring solutions since 1986. Over 1,500 companies, including 15 of the top 21 U.S. power utilities at peak deployment, have relied on DPS equipment to centralize and manage alarms across mixed-protocol networks.
If you're evaluating an alarm aggregation system or trying to integrate equipment your current tools can't reach, we'll help you figure out the right approach for your specific environment.
