Assured Services Session Initiation Protocol (AS-SIP)

REDCOM is a key partner with Defense Information Systems Agency (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 superset of DoD specific SIP signaling standards which incorporate additional security and assured service requirements.

AS-SIP facilitates these essential DoD features:

  • Multi-Level Precedence and Preemption (MLPP) which establishes communications priorities, ensures system and network access and control, and manages both precedence and preemption assuring end-to-end War-fighter communications connectivity
  • Secure Real-Time Transport Protocol (SRTP) and Transport Layer Security (TLS) which enhances communication security by enabling encrypted communications.
  • Differentiated Services Code Point (DSCP) which improves traffic management by providing priority packet routing across the network.
  • Traffic engineered loads defined through bandwidth budget controls which include Assured Services Access Control (ASAC), and Dynamic ASAC (DASAC).  

REDCOM’s equipment has been certified interoperable by the DISA Unified Capabilities Certification Office (UCCO). Adherence to AS-SIP and industry standard SIP means REDCOM’s equipment is interoperable with any other AS-SIP / industry standard SIP equipment and end instruments (EIs). Additionally, REDCOM systems can provide interoperability between the latest AS-SIP end instruments, VoIP end instruments, radios, legacy (TDM) equipment, and rugged magneto crank-phones.
