Warfighters currently use a wide range of communications and encryption technologies that were not designed to be compatible. VoIP and legacy equipment are all from different generations of technology. The REDCOM HDX•C with TRANSip® delivers the secure converged network solution to serve the warfighters’ communication needs. Regardless of your mission, TRANSip converges tactical and strategic networks from a broad range of technologies for maximum communications interoperability, including SIP, SCIP, V.150.1, GSM, radio, SATCOM, ISDN PRI, Euro PRI, IPv4 and IPv6.

REDCOM’s HDX•C equipped with the TRANSip technology suite provides an innovative telecommunications solution that leaps ahead of first generation switching systems, integrating VoIP Call Management, Media Gateway Services, Media Gateway Controller, and other next generation features. REDCOM’s Media Gateway has dozens of legacy interfaces available, giving warfighters all the benefits of IP while preserving the functionality of their existing telecom infrastructure.

Supports AS-SIP Requirements

REDCOM is a key partner with DISA in implementing the Assured Services Session Initiation Protocol (AS-SIP), as defined by the Unified Capabilities Requirements (UCR) technical standards for telecommunication switching equipment. AS-SIP is a defined set of SIP signaling standards incorporating DoD Assured Service functionality, including MLPP for establishing communication with resource priorities, ensuring system and network access and control, and providing precedence and pre-emption policies to assure connectivity for command and control.

Advanced Secure Gateway Application

With REDCOM’s Advanced Secure Gateway Application, a warfighter located in a non-secure VoIP or TDM network using a SCIP device can simply dial the published VoSIP user’s station number and the secure call will be translated correctly and delivered to the VoSIP user. No secondary dial tone or over-dialing is required for calling a black number and speaking securely to a classified VoSIP user. The REDCOM Advanced Secure Gateway Application was successfully demonstrated and documented at the Joint Users Interoperability Communications Exercise (JUICE) at Fort Monmouth, NJ.

MLPP and ANSI 619a

The HDX•C provides a Multi-Level Precedence and Preemption (MLPP) software capability (including ANSI 619a) for end-to-end warfighter communications. This essential element of command and control (C2) ensures that the most important calls get through and are able to “tandem” and deliver priority calls to the end location and warfighter.

Secure conferencing  

The secure conferencing capabilities of the HDX•C provides a powerful set of tools for warfighter communications. Several conferencing styles are available, including “progressive” (participants added one at a time), “meet-me” (participants meet at a valid number at a specified time), and “preset” (conference controller initiates the event, adding participants as they answer).

HDX•C supports secure, tactical, and strategic VoIP communications

HDX•C with TRANSip supports secure VoIP communications and also enables IP and TDM users to communicate securely via SCIP and V.150.1. HDX•C connects multi-technology networks and provides a secure link for Joint, NATO, and Coalition Forces. V.150.1 aids the transmission of modem communications over IP networks, and has largely been adopted by the military and government sectors. SCIP incorporates the V.150.1 protocol for secure communications.

Interoperable with commercially-available voice encryptors, REDCOM’s SWT-R interface board for the HDX•C ensures that the voice streams are encrypted and secure. HDX•C allows a Type 1 Secure VoIP phone to call directly and securely to a secure analog device. Also, HDX•C enables a KY-68 phone, dialing 10 digits, to communicate securely with a Type 1 Secure VoIP phone.

The reliable transition to IP

IP is changing the way the government and military communicates. In the transition to VoIP, wholesale replacement of legacy TDM is not only expensive but unrealistic. REDCOM’s HDX•C was designed to be a fully integrated TDM and VoIP migration platform so that warfighters can migrate to IP when it makes sense. Legacy devices and networks must continue to be supported. HDX•C with TRANSip offers a low risk, flexible, and cost-effective transition to VoIP.  With HDX•C you can start with as few as 100 IP subscribers. Its extensive TDM capabilities also allow you to retain legacy equipment. HDX•C is a true drop-in replacement that facilitates simple transition to VoIP.

Manage IP SATCOM bandwidth with advanced VoIP trunk features

VoIP consumes a considerable amount of SATCOM bandwidth if not controlled. The HDX•C’s advanced standards-based VoIP trunk features help manage the SATCOM bandwidth consumed in IP based voice communications. Considerable SATCOM bandwidth can be saved during modem-driven secure voice conversations by using HDX•C’s integrated V.150.1 standard. Advanced VoIP trunk features manage the quantity of calls allowed over SATCOM links, as well as the amount of bandwidth a user can consume.

Distributed & redundant architecture means enhanced survivability

The HDX•C system architecture minimizes the risk of single point failures as it distributes resources system-wide and network-wide, using multiple points of direct access. HDX•C features REDCOM's distributed system architecture which employs multiple call controllers which provides a strong defense against a Denial of Service (DoS) attack. HDX•C provides continuous service with innovative alternate routing that combines IP routes and TDM trunks.

Scalable and stackable

Based on REDCOM's distributed architecture, HDX•C is scalable and stackable with a "building block" approach. A shelf can function as a complete system by itself or be stacked to make systems up to 16,000 ports (4,000 non-blocking).

Command & Control Features

• Link Command System (LCS): a software package that operates as an attendant/operator on a standard PC. Its graphical user interface can be used with a touch-screen monitor and features keyboard based dialing, paging, conferencing, attendant-to-attendant calls, access restrictions and more.
• REDCOM's ClusterNet™ technology connects multiple sites and allows them to function as a single, truly integrated switching system. ClusterNet can be used with REDCOM HDX•C, REDCOM SLICE® and REDCOM SLICE® 2100™ to create a scalable communications system designed for a distributed network configuration.
• MAUI (Maintenance Administration and User Interface) provides a single point of OA&M. MAUI is an intuitive GUI that simplifies the configration and maintenance of your REDCOM network.
• Tactical Traffic Metering Package (TTMP): a software package that enhances traffic analysis & CDR/LAMA features of your HDX•C. TTMP allows network administrators to collect & analyze data over multiple sites.
• HDX•C includes Call Detail Recording (CDR) and Station Message Detail Recording (SMDR) to provide a record for both IP and TDM based calls. CDR can be enabled for all calls, including trunk, tandem, and local.
