Channel Bank Replacement Using the TC8714-2
This application note takes a look at the TC8714-2 and how it can be used for the replacement of an existing channel bank, or for new applications where a small number of interfaces are being utilized.
Direct Transfer Trip: Three Simple Solutions to Connect with Fiber, T1 or Ethernet
In this application note, we explore three simple, drop-in solutions as a replacement for leased telephone lines in Direct Transfer Trip systems, providing more cost-effective and reliable connectivity.
Using JumboSwitch to Preserve Legacy Devices That Don't Connect to Broadband Networks
A key problem we have been able to solve for many customers is providing solutions that allow them to continue using legacy devices that do not connect to a broadband network.
Staying NERC CIP Compliant When Connecting Third-Party Facilities: Two Customer Examples
This article, we will cover two cases when we deployed a solution for utility customers with concerns surrounding NERC (North American Electric Reliability Corporation) CIP (Critical Infrastructure Protection) requirements and cyber security requirements.
V.24 Two-Way Radio Connections Using the TC3847-3
V.24, a synchronous RS-232 standard can be applied in much the same way as copper leased lines are used, and the migration to an IP-based solution is done in the same manner. This application note details two-way radio connection via the TC3847-3
IEEE 1613 Compatible Substation Line Sharing Switch
A common application for substation meter polling is the use of a substation line sharing switch (SLSS) allowing the sharing of phone lines between multiple devices. SLSS devices typically are designed with 8 ports, this application note describes a more flexible solution of 4-28 ports using a modern flexible design.
Using TC Communication products to connect SEL teleprotection relays using Mirrored Bits over an Ethernet connection
Answers to common questions on the impact of using Ethernet solutions within applications involving Mirrored Bits.
TC Communications' IEEE 1613 Solution Guide
TC Communications has solutions that meet the IEEE Standard Environmental and Testing Requirements for Communications Networking Devices Installed in Electric Power Substations.
Ethernet migration solution for OC3 microwave links
A California natural resources agency needed a quick migration solution for existing OC3 microwave links. The fiber portion of the network had been converted to Ethernet but the ten microwave links could not be switched over as easily.
Analog radio system redesign utilizes TDM and IP backhaul
An East coast county emergency network was faced with retiring 4-wire E&M leased circuits by their local carrier. These circuits were utilized as the primary connectivity for their mission critical radio system between dispatch and 4 fire stations.
Testing and Implementing Teleprotection over IP MPLS with JumboSwitch C37.94 to IP Gateway
An Australian power company upgraded their network to MPLS, but had no fiber available to implement primary and backup teleprotection links. The JumboSwitch C37.94 IP Gateway passed a variety of Latency and Operating Time tests for 87L Line Differential protection and was implemented as an easy edge solution on their MPLS network.
Migrating from TDM to Ethernet for Legacy & Teleprotection Devices
With the rapid convergence of data, voice and video, more Power Utilities are migrating from TDM systems and serial communications to Ethernet for simplicity, scalability, and better interoperability between Control Rooms and different types of substation IEDs.
Extend Phones via Ethernet, RS232 or Fiber Optics
Instantly turn an Ethernet, RS-232 or Fiber Optic circuit into a voice network by simply plugging in an analog telephone is an extremely useful application. Intended to provide flexible point-to-point telephone service in even the harshest of conditions.
JumboSwitch Voice over IP Application Note
The JumboSwitch® offers TC3848 modular support two unique technologies/applications to implement and integrate voice over a JumboSwitch IP backbone.
JumboSwitch Smart Grid Applications
A smart grid integrates electricity delivery systems with modern interactive digital technology to offer an intelligent, less costly and more reliable delivery of electricity from supplier to consumer.
JumboSwitch Cellular Backhaul Applications
The need for more bandwidth efficiency is most noticeable in mobile backhaul applications. Changing cell phone habits and the emergence of 3G and 4G technologies have triggered an exponential increase in data content for mobility backhaul. This has created an ongoing need to add more transmission capacity.
Transportation & ITS Applications
A heavy rail system is an electric railway with the capacity to handle a heavy volume of traffic compared to a “light rail” system. Critical applications for heavy rail systems include: voice, video, data, and real time information between Network.
