Reserve Your Seat TodayPathnet, a wholesale telecommunications provider, needed a practical way to distribute environmental and housekeeping alarm visibility to multiple collocation tenants while also feeding the same alarms to its Network Operations Center (NOC). DPS Telecom delivered a purpose-built Intelligent Alarm Distribution Shelf (IADS) and a reliability-focused design that helped ensure dependable alarm data delivery.
| Industry | Telecommunications (wholesale provider with collocation tenants) |
|---|---|
| Company Type | Wholesale telecom network operator and facility provider |
| Geography / Coverage | Nationwide network; 7,700 route miles with an additional 3,400 miles under construction or tied to swap commitments |
| Primary Challenge | Distribute site environmental and housekeeping alarms efficiently to multiple collocated companies while maintaining NOC visibility |
| Solution Deployed | DPS Telecom Intelligent Alarm Distribution Shelf (IADS) with periodic self-diagnostics and shelf-failure alarming |
| Key Result | Enabled alarm distribution from the facility to both Pathnet NOC and co-located customers with added confidence in monitoring reliability |
| Products Used | Intelligent Alarm Distribution Shelf (IADS); T/Mon LNX (current IAM equivalent) |
Pathnet operates as a wholesale telecommunications provider offering broadband access and transport solutions to underserved markets. With a convergent network, Pathnet supports traditional carriers and emerging providers (including Internet service providers (ISPs) and competitive local exchange carriers (CLECs)) by enabling expansion into new markets without the same level of capital investment typically required to build new infrastructure.
Pathnet's network spans 7,700 route miles, with an additional 3,400 miles under construction or tied to swap commitments. In addition to serving network customers, Pathnet leases space to multiple companies that collocate in its facilities.
Lee Wells, Pathnet's Senior Timing & Telemetry Engineer, described the operational requirement: collocation tenants expected visibility into the environmental and housekeeping alarms produced within the site as part of their space lease.
Pathnet needed a way to present the right alarm data to different tenant organizations without creating an inefficient or unmanageable distribution approach. As Wells explains, "The problem was that we had different companies that co-located with us. We would lease space to them out of our facility and part of that package included visibility to the different environmental and housekeeping alarms produced within that site. There wasn't a solution that could handle that type of function with any efficiency at all."
In collocation environments, a single site can generate many alarm points from power systems, HVAC, security sensors, and other facility equipment. The operational challenge is not only collecting those alarms, but also distributing the appropriate alarm feeds to multiple recipients in a controlled, supportable way, while still ensuring the NOC has complete visibility.
DPS Telecom delivered a solution for Pathnet by developing the Intelligent Alarm Distribution Shelf (IADS). This success was made possible through the expertise of our sales consultants, the innovation of our design team, and the dedication of our engineering staff.
The IADS empowers Pathnet to transmit alarms from their cage to both their Network Operations Center (NOC) and co-located customers. In practical terms, this kind of distribution shelf acts as an alarm mediation and fan-out layer: it takes alarm indications coming from facility and infrastructure systems and makes those alarm outputs available to multiple parties who need visibility.
To enhance reliability, DPS Telecom integrated an innovative fuse module that conducts periodic self-diagnostics on the IADS. In the rare event of a shelf failure, a relay immediately triggers an alarm. This allows for prompt awareness of the issue, helping operators distinguish between "no alarms" and "alarm reporting path failure" at the shelf level.
Commenting on DPS Telecom's ability to build custom solutions, Wells says, "You are really good at listening to the customer's needs and incorporating them into the product you have been able to do anything we have asked. You built it on the spot and had it ready for us when we asked you to."
For telecom operators who need to distribute alarm data across internal teams, external partners, or tenant organizations, DPS Telecom routinely applies the same design principles demonstrated here: clear alarm ownership boundaries, dependable alarm transport, and explicit alarming for failures in the monitoring path.
With the IADS in place, Pathnet could provide alarm visibility to its collocation tenants while maintaining NOC awareness of the same facility and housekeeping conditions. The built-in self-diagnostics and immediate relay-based alarming for shelf failures helped increase confidence that the alarm distribution mechanism itself would not silently fail.
This outcome supports a core NOC requirement: operators and tenants need to know not only when a site condition goes into alarm, but also when the monitoring and distribution equipment requires attention.
The original IAM concept combined alarm mediation with notification capabilities. For modern deployments, DPS Telecom recommends the T/Mon Alarm Master family as the current equivalent approach for centralized alarm management and distribution.
The T/Mon master offers greater notification customization and strong support for modern network protocols. This helps teams tailor how alarms are routed, escalated, and acknowledged across operations groups.
T/Mon serves as a multiprotocol, multifunction alarm management platform that consolidates alerts from diverse devices into one intuitive interface. This allows operators to monitor legacy and modern equipment simultaneously without the need for multiple systems.
Beyond basic notifications, T/Mon supports advanced alarm forwarding and derived alarms for automating responses based on complex conditions. These capabilities help drive faster and more accurate reactions to critical events, especially in environments where alarms must be shared across internal operations and external stakeholders.
Whether you are replacing an outdated IAM or expanding an existing monitoring network, DPS Telecom recommends T/Mon LNX as a scalable path to consolidate alarm collection, distribution, and notification in one operational view.
Common shared alarms include environmental and housekeeping conditions such as power status, HVAC conditions, battery plant and rectifier alarms, security contacts, and other facility monitoring points.
Tenants often need visibility into the same site conditions, but each organization may require its own alarm feed and notification rules. Doing this manually can be inefficient and difficult to maintain as tenant mixes change.
If the distribution layer fails silently, downstream recipients can lose visibility even though field conditions are changing. Self-diagnostics and shelf-failure alarming help ensure the alarm path itself is supervised.
If notification requirements have expanded (email, SMS, escalations), or if the environment has grown to include more protocols and devices, modernizing to a current alarm master such as T/Mon LNX can simplify operations.
If you need to distribute alarm visibility across a NOC, remote teams, partners, or collocation tenants, DPS Telecom can help you design the right approach using proven alarm distribution and alarm management building blocks.
