DISA UC APL TCP Plug-in Modules Specifications Product Photography

Certified as a Local Session Controller (LSC)

The SLICE 2100 Version 4.0 is certified as a Local Session Controller (LSC) by the Defense Information Systems Agency (DISA) Unified Capabilities Certification Office (UCCO) and is listed on the Unified Capabilities (UC) Approved Products List (APL). Warfighters on today’s battlefields can be confident their calls will get through when backed by the extensive interoperability of the SLICE 2100.

Interoperability & IP Convergence

Interoperability and the need for a low risk migration to IP, necessitates that legacy devices/networks continue to be supported to retain communications integrity. REDCOM’s SLICE 2100 is designed as a fully integrated TDM/VoIP platform that converges tactical and strategic networks for maximum interoperability including: SIP, AS-SIP/UC-SIP, SCIP, V.150.1, GSM, Radio, SATCOM, ISDN PRI, Euro PRI, IPv4, IPv6, and Magneto. Warfighters can leverage existing communications functionality while migrating to current and next generation communications.

Precedence & Preemption

The SLICE 2100 provides Multi-Level Precedence and Preemption (MLPP), including industry standard ANSI 619a, for comprehensive end-to-end war-fighter communications. This essential element of Command and Control ensures that the most important calls get through during critical situations.

TRANSip® IP Technology Suite

TRANSip is REDCOM’s IP telephony technology suite that integrates the benefits of IP and TDM technologies, providing Call Management, Media Gateway Services, Media Gateway Controller, IP Subscriber Database, and Call Detail Records. REDCOM’s Media Gateway provides warfighters with reliable five nines connectivity between multiple legacy interfaces and current generation communications platforms.

Secure Communications

REDCOM’s SLICE 2100 connects multi-technology networks and supports secure communication via SCIP and V.150.1. In addition, Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS) are available to provide media and SIP signaling encryption as well as client authentication. REDCOM’s Secure Device Module ensures SLICE 2100 interoperability with commercially available voice encryption devices. SLICE 2100 allows a Type 1 secure IP phone to directly and securely call a secure analog device.

Extensive Conferencing

REDCOM’s SLICE 2100 supports several conferencing styles, including progressive (participants added one at a time), meet-me (participants meet at a specified time), preset (conference controller initiates the event, adding participants as they answer) or any combination of these methods.

Advanced Secure Gateway

With REDCOM’s Advanced Secure Gateway Application, a warfighter on the DSN network using a SCIP device can simply dial the published station number of a user on a classified network.  The published number is translated and delivered to the classified user without requiring a secondary dial tone or over-dialing. When SCIP devices on the DSN and REDCOM Gateway go secure, a classified conversation can be held between the two users. Additionally, REDCOM’s Advanced Secure Gateway provides secure conferencing between users on multi-technology networks, facilitating secure conferencing between Joint, NATO and Coalition Forces. This was successfully demonstrated at the 2012 Joint Users Interoperability Communications Exercise (JUICE).

Military and Commercial Radio Interface

The SLICE 2100’s Radio Interface Module allows any REDCOM system phone to dial out to a remote radio, and allows a radio to dial directly into the system and ring a phone, make an outside call, or call another remote radio system. Full two-way calling with Push to Talk (PTT), Voice Operated Transmission (VOX) or Carrier Operated Relay (COR) is supported. REDCOM technology also removes the repeater squelch found in commonly used analog radios. REDCOM’s Radio Interface is interoperable with encrypted military radios and verifies the radio is secure before the voice transmission is enabled.

Administration & Control

REDCOM offers products to facilitate a single point of OA&M at your Network Management Operations Center.

Link Command System (LCS) is a PC-based GUI call management system that delivers extensive call control, call handling, directory assistance requests, and call queue management.  

MAUI (Maintenance Administration and User Interface) is a PC-based GUI which provides a single point for OA&M, simplifying the task of administering your REDCOM SLICE 2100.  


REDCOM products are on the Unified Capabilities Approved Products ListThe SLICE 2100 with software version 4.0 is on the Unified Capabilities (UC) Approved Products List (APL) and certified for use as Local Session Controller (LSC) by the Defense Information Systems Agency (DISA) Unified Capabilities Certification Office (UCCO). The UC APL lists products that are available to the Department of Defense (DoD). To be placed on the UC APL, products must be evaluated and achieve certification for information assurance (IA) and interoperability (IO) by the Joint Interoperability Test Command (JITC).

The LSC is responsible for enforcing Assured Services Session Initiation Protocol (AS-SIP) trunk policies, such as Multi-Level Precedence and Preemption (MLPP), for calls made from SIP phones. MLPP ensures that the most important calls get through during crisis situations and it is an essential element of command and control.

The REDCOM SLICE 2100 offers powerful UC capabilities including AS-SIP, IPv4/IPv6 dual stack, MLPP, seamless converged TDM/IP interoperability, secure communications via the Secure Communications Interoperability Protocol (SCIP), V.150.1, and much more.

SLICE 2100 Tactical Communications Package (TCP)


REDCOM’s Tactical Communications Package (TCP), equipped with the REDCOM SLICE 2100, is interoperable, battle-tested, and portable. The case-mounted switches  meet stringent government and defense specifications for impact and vibration, able to endure the harsh conditions of airlift, seaborne and off-road transport. 


Military, emergency responders, carriers and utilities rely on REDCOM’s 99.999% ( “five nines”) Carrier-Class reliability for dependable performance. The most challenging conditions on earth: Alaskan cold, South Pacific heat/humidity and Middle East desert heat/sand are all home to REDCOM systems.


The SLICE 2100 TCP is completely customizable, enabling integration of specific communication equipment, including encryption devices, for unique operational requirements.  REDCOM’s SLICE 2100 TCP can be prewired and configured to be set-up and operational within minutes of deployment and a flip of the power switch.
