Key facts

  • All communications networks on a single screen
  • Certified secure domain separation 
  • Full IP network technology
  • Field-proven
  • One-stop-shop for secure communications

The most innovative full IP based VCS on the market 

R&S®M4ACS takes full advantage of innovative IP resilience and strong security 

R&S®M4ACS clearly separates red/secure from black/non-secure domains. Operators can simultaneously access two security domains with the same audio accessories and clear audio routing principles. The two security domains are separated by a TEMPEST Level A, Common Criteria BSI-certified R&S®Trusted Audio Switch. Each security domain has independent core equipment to access specific legacy and IP interfaces with distinct demarcation equipment. The versatile R&S®M4ACS can accommodate  various installation scenarios including fixed, deployable and mobile systems.

Features & benefits

All communications networks on a single screen

R&S®M4ACS has an innovative graphical user interface (GUI). The GUI enables secure and convenient access to all communications, while displaying both separated security domains for full operational awareness.
