Military, Aerospace, & Government

Preserve legacy equipment and update to an IP network in harsh environments.

JumboSwitch® Multi-service Ethernet Switch

Secure and reliable equipment

For over 30 years, TC Communications has developed tough, reliable industrial hardened voice and data communications products for Layer 2 networks, designed for use in demanding military and government applications, including Navy, Air Force, and Army operations.

Industry Solutions

Phone Extensions in Mission Control Training Center (MCTC) - Connect analog phones using IEEE 802.3p/Q QoS prioritization to guarantee consistent, uncompressed voice regardless of network traffic. Use existing phone equipment for FXS-FXS or FXS-FXO channels with no need to re-train users. Experience the following features:

  • Instant ringing to a remote phone by picking up the line
  • Call distribution to multiple locations anywhere in the VoIP network
  • Live temperature and power usage monitoring for each card
  • Call transfer without a receptionist using Auto Attendant
  • Call forwarding, music on hold, fax and caller ID

TC products allow users to complete migration from a legacy network to integrate voice and data over an Ethernet/IP network. Merging a self-contained phone system with Ethernet and call processing features of PBX is seamless. TC products are also able to connect from miles apart with consistent and clear quality.

Many military communication networks still need 600-ohm analog radios or modems, but network infrastructure is becoming IP-based. Using multi-service Ethernet and various gateways, JumboSwitch® helps preserve legacy devices and update to an IP network.

The MoIP Gateway is being used to link analog telephones or legacy dial-up devices including data modems, PBXs and key systems over Ethernet/IP or MPLS networks. The JumboSwitch TC3848-3/4 is an exceptional solution for users looking to move that route.

Case Studies

Military unit uses mobile VoIP virtual PBX network

The Battle Group needed to stay connected with a Defense Switched Network (DSN) that required dispatch between 17 communication sites and a Central Command Center (CCC). Three main requirements were also needed for the proposed system. Ultimately, the military group chose the JumboSwitch due to its robust features that included scalability, a self-contained phone system and an industrial hardened version.

Airfield Migrates to Fiber Network Improving Communications Quality and Operations

They were facing multiple challenges impacting two of their communications networks. They had been dealing with signal quality issues, degrading copper and system shutdowns. The airfield was in search of a single vendor that could migrate their communications network including their radio network between the tower, their weather command post and radar approach control (RAPCON). In addition, Glide Slope, Localizer data and telephony for two runways had to be integrated with their headend at RAPCON.

Juggling a Backbone Mandate While Integrating with an Ongoing Upgrade

This airfield was mandated to upgrade its existing copper backbone to fiber, resulting in the need to upgrade their communications network. In addition, the airfield was performing an upgrade of their airfield radio system which needed to integrate with the proposed communications network solution. TC Communications assisted in migrating the entire communications network including communications between ground to air transmit receive (GATR), air traffic control (ATC), and the weather command post.

"Thanks for looking into the module so quickly. We've been very happy with TC Communications equipment and service to date, and I've been recommending you guys pretty heavily to people we run into."
- Den DeCicco, defense contractor EG&G
"I am very impressed with the level of support you have given me with the trouble of shooting and advance trouble shooting and advance replacement....Since the units I use in my system have been superseded by newer models, the Tech Support staff had to go an extra step and have 2 units programmed to work with my older system. That is what I call support."
- Gary McCaughey, Airport Security Coordinator at Columbia Metropolitan Airport
