Reserve Your Seat TodayOkuda Sangyo Philippines, a systems integrator, supported a major Philippine electric grid utility that required remote monitoring over E1 transport. DPS Telecom engineered a custom solution - including E1 RTUs, an E1 WAN mux, and a VLAN router - that the customer could test in-network and ultimately approve for purchase.
| Industry | Electric power transmission / utility |
|---|---|
| Company Type | Systems integrator (Okuda Sangyo Philippines) supporting a major utility customer |
| Geography / Coverage | Philippines (planned expansion across 3 regions) |
| Primary Challenge | Deploy remote monitoring using E1 connectivity and utility-grade power requirements (125 VDC) for a large, distributed network |
| Solution Deployed | Custom-built network monitoring system with E1 RTUs reporting to a central master station via E1 WAN muxes, plus VLAN routing |
| Key Result | First-article demo unit shipped for testing; the utility validated the design and made a purchase; expansion planned |
| Products Used | DPS Telecom custom E1 RTUs, E1 WAN Mux, VLAN Router (with 125 VDC power supply requirement) |
Okuda Sangyo Philippines is a systems integrator that designs and delivers monitoring and communications solutions for some of the largest public and private organizations in the Philippines. Willie Ledesma, Account Officer for Okuda Sangyo Philippines, engaged DPS Telecom when he needed remote monitoring equipment for a customer project.
After researching monitoring options online, Ledesma contacted DPS Telecom to discuss requirements for a large utility customer: the National Transmission Corporation of the Philippines, which has since become the National Grid Corporation of the Philippines.
The project required a network monitoring approach that would work with E1 connectivity and a centralized master station architecture. In addition, Okuda's utility customer requested equipment suitable for their environment, including a 125 VDC power supply option for demo units.
From an implementation perspective, this meant the monitoring hardware had to be engineered for the customer's E1 transport plan, support the right site-to-master reporting method, and fit into the customer's networking segmentation requirements (VLAN routing).
Okuda Sangyo Philippines and DPS Telecom collaborated on a custom-built monitoring system that met the customer's transport and network design needs. The solution included:
This type of architecture is commonly used when organizations need a repeatable remote-to-central monitoring design that can scale to many sites while remaining compatible with existing transport and networking standards.
"It was a custom build request. It was very gracious for DPS to design and build the equipment and let us test it in the network."
To accelerate technical understanding and adoption, Ledesma visited DPS Telecom headquarters in Fresno, CA, USA for factory training. Following the training, Okuda promoted the solution to customers and requested demo units with 125 VDC power supplies to support field evaluation.
DPS Telecom's Engineering and Production teams worked closely with Sales to support the requested adjustments and deliver a first-article demonstration unit to the Philippines for testing. This approach helped the utility validate the design in their network before committing to a broader deployment.
After in-network testing, the customer approved the system and made a purchase. Okuda Sangyo Philippines then began planning expansion of the E1 RTU deployment to additional sites across the Philippines.
"The plan is to expand to sites in all 3 regions of the Philippines. It's not a hard sell because the equipment is really good."
"Our client saw the beauty of the equipment and its use, so they made a purchase," Ledesma said.
DPS Telecom RTUs (custom E1 RTU configuration for the customer's monitoring and reporting requirements)
When you need to build remote monitoring around specific transport (such as E1), DPS Telecom can engineer the appropriate RTU and communications approach so the solution fits your operational environment instead of forcing a redesign.
Common questions engineering teams and operations managers ask when deploying utility monitoring over constrained or standardized transport (such as E1) and segmented networks.
An RTU (Remote Terminal Unit) is a remote endpoint that gathers status and alarm data from field equipment and reports it back to a central location. In many monitoring architectures, RTUs act as the on-site interface between physical plant conditions and the master station.
E1 is a widely deployed digital transport standard in many regions and can be part of an existing utility communications infrastructure. When E1 is already standardized, using it for monitoring traffic can simplify integration and preserve existing network plans.
A WAN mux (multiplexer) aggregates and transports traffic across the WAN. In an E1 monitoring architecture, WAN multiplexing can be used to carry remote-site reporting back to a master station across available E1 circuits.
VLANs (Virtual LANs) are commonly used to segment networks for operational, security, or administrative reasons. Monitoring deployments may require VLAN routing so alarm and telemetry traffic can traverse the correct segments while remaining aligned with the customer network design.
Yes. Many deployments require adaptations for transport type, interfaces, power input, and integration requirements. In this case, DPS Telecom supported a custom build and provided a first-article unit for in-network testing before purchase.
If you are planning remote monitoring for a utility, telecom, or industrial network and need equipment engineered to your transport, power, and network requirements, DPS Telecom can help you design the right approach.
