Application Notes

Application notes are particularly useful for illustrating alternative ideas for network designs. The application notes listed below examine popular Ethernet, voice & data networking solutions.


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.

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.

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 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.
