Regardless of the military mission, REDCOM’s portfolio of DISA UC APL tested and certified switching equipment delivers highly secure, interoperable, rugged and reliable VoIP solutions for tactical and strategic applications. Whether warfighters need the transportability and small footprint of REDCOM’s SLICE® 2100, SLICE® 2100 Micro or SLICE® IP Micro for tactical communications deployments, or the scalable and stackable HDX•C “building block” approach for reach back support in the field, REDCOM has the secure, tactical, and strategic solution platforms to meet the Department of Defense’s requirements. REDCOM enables secure and interoperable warfighter communications with TRANSip®, the breakthrough technology that delivers secure tactical and strategic integrated VoIP for Joint, NATO, and Coalition Forces.

Assured Services Session Initiation Protocol (AS-SIP)

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 (Multi-Level Precedence and Preemption) for establishing communication with resource priorities, ensuring system and network access and control, and providing precedence and preemption policies to assure connectivity for command and control. This essential element of command and control ensures that the most important calls get through and are able to “tandem” and deliver priority calls for end-to-end warfighter communications.

Local Session Controllers (LSC) 

Local Session Controllers (LSC) are responsible for protocol conversion from line-side analog, digital, and IP to trunk-side AS-SIP. Over the years, REDCOM has demonstrated true communications interoperability using published telephony standards. The technologies integrated into REDCOM’s converged network will include but not be limited to: IPv6/IPv4 dual stack REDCOM switches, secure and non-secure IP and analog end devices to include wired, wireless, ISDN, radios, a deployed secure gateway application, AS-SIP trunking, SIP trunking, and IP circuit extension. MLPP ensures that the most important calls get through during crisis situations and it is an essential element of command and control. REDCOM’s HDX•C, SLICE® 2100™ and SLICE® IP Micro switches are converged network solutions that also support AS-SIP signaling requirements for Local Session Controllers (LSC). In addition, the LSC is responsible for enforcing 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.


REDCOM products are on the Unified Capabilities Approved Products ListREDCOM’s software Version 4.0 for the HDX and SLICE family of products, along with Teo® IP phones as the end instrument, have been placed 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).

With Version 4.0 certification and listing on DISA's UC APL, warfighters on today’s modern battlefield can be confident that their calls will get through, backed by the reliability and extensive interoperability of REDCOM products operating in a Joint environment.
