Sunhillo's TDM to IP solutions span across multiple industries including:

FAA | DoD

.

Power Utilities

Telecom

Industrial

Many systems, including the FAA, depend on TDM-based services provided by telecom carriers (approx. 21,000 services – many using T1 Line connectivity). TDM services will phased out and migrated to IP over the next few years. The TDM services used in the FAA NAS include voice, surveillance, weather, maintenance systems, and inter-facility / flight data a list that encompasses nearly the entire NAS.

Sunhillo’s Solution minimizes risk and provides a TDM to IP solution to meet the FAA’s needs as well as other industries like Power Utilities & Telecom that are transitioning from TDM leased lines. Using Sunhillo’s TDM to IP products like the RICI Gateway, Asbury, Ventnor Concentrator, and LITE Software Suite will help ease the transition and provide a safe, reliable solution.

Sunhillo’s TDM to IP solutions include: 

  • FAA FTI TDM Gateway
    • Sunhillo TDM to IP products are FENS enabled
  • Bridge HDLC lines over Ethernet
    • Extend the life of legacy equipment without the use and cost of TDM leased lines 
  • Synchronous Serial to IP Conversion
    • Plug and play conversion with Power over Serial or Power over Ethernet using the Asbury
  • ASYNC or HDLC to CMHP, SWIM, Active MQ
    • Multiple formats supported

Sunhillo's FAA TDM to IP Featured Products

Sunhillo’s Real-Time Interface & Conversion Item (RICI) Gateway has been specifically designed to address the needs associated with the elimination of leased TDM lines. As such, the product comes equipped with a suite of built in user configurable options that allows the user to configure the RICI Gateway for their required needs depending on where they are in the migration path relative to the elimination of leased TDM lines or as commonly referred to Sun Setting on TDM.

The Ventnor Concentrator is intended to interface to a number of different devices such as NAV Aid Devices (VOR, RVR, ALS…), Weather Sensors (ASOS/AWOS), and Radar Flight Data Equipment. The Ventnor Concentrator supports up to 16 serial ports. Additionally, the Ventnor Concentrator has been designed to provide a CMHP RMLS connection that provides monitoring of the Ventnor Concentrator hardware, and individual channel configuration and status.

As part of the TDM to IP initiative, there has been a move to transition serial communication circuits to IP circuits. Sunhillo’s Legacy Interface Test Equipment (LITE) has been specifically designed to provide a platform for testing FAA Legacy serial interfaces and providing an environment to help in the transition from TDM to IP. The LITE is a fully configurable simulation tool.

Sunhillo's TDM to IP Solutions for Power Utilities and Telecom

Sunhillo developed the Asbury specifically for sustaining legacy equipment by eliminating the need for costly serial and TDM lines

FAA TDM to IP Concept of Operations

Specifically for the Utilities and Telecom industry, the Asbury has been successfully tested in a power utility environment with a SEL Relay in a point to point Carrier Grade Network with a total combined delay of 36 milliseconds.  Protection Relaying Applications include:

  • Breaker Failure
  • Direct Transfer Trip Signals (DTT)
  • Permissive Overreaching Traffic Trip (POTT)
  • *SEL Mirrored Bits Supported
  • PoE or Power over Serial

Sunhillo's TDM to IP products for Utilities/Telecom

The Asbury solves your data connection needs moving from expensive and outdated Serial and TDM lines to cost effective Ethernet networks. The Asbury product is a compact, low cost, single-channel serial to ethernet conversion device ideally suited for Legacy Serial/TDM lines moving to IP applications. It is contained in a form factor that allows it to be attached in-line to a device or cable with a male DB-25 connector, and an RJ45 connection on the opposite side for LAN.
