Local Session Controller - JITC Compliance

The Ribbon Application Server 11.2 has successfully completed US Department of Defense Joint Interoperability Test Command (JITC) testing as both an Enterprise Session Controller (ESC) and Local Session Controller (LSC). (Note: Ribbon Communications is the merger of GENBAND and Sonus Networks -- some elements may still appear in the APL under the prior names but there is no change to product functionality.) This certification effort was completed in concert with Polycom VVX phones and Polycom Treo as routine only end instruments.  Certification also includes Teo IP phones and Avaya 1100 series phones.

The Ribbon Application Server shares its heritage with the Nortel AS 5300 R1.0 and R2.0 that was widely deployed in the US Department of Defense for Command and Control operations. The Ribbon Application Server offers a highly scalable, fully virtualized, standards-based, upgrade option for these and similar deployments. Ribbon’s solution easily scales to hundreds of thousands of endpoints per node (max of 2 million) and is actively deployed in mission-critical environments with standards-based SIP and ASSIP endpoints. Of course, modern soft clients are also supported.  There is no proprietary endpoint lock-in; the solution’s ESC certification and scale make it ideally suited for graphically redundant, private clouds. A modern architecture for today's mission. 

JITC Certification - Security Assurance

JITC certification affords US defense departments, as well as certain government contractors, assurances that the Ribbon Application Server (GENBAND EXPERiUS R11.2) will interoperate within their networks and support certain Multilevel Precedence and Preemption (MLPP) capabilities. Certification further affirms the solution’s ability to comply with tested Information Assurance requirements associated with security and survivability services. 

JITC Certified Session Controller Advantages:

  • Carrier heritage assures massive scale and geo-redundancy
  • No proprietary lock-in – supports SIP and ASSIP devices
  • Works in concert with Ribbon (Sonus) Certified SBCs
  • Tested with industry-leading Polycom VVX phones
