Packet Technologies and Systems Committee

PTSC develops standards related to services, architectures, signaling, network interfaces, next generation carrier interconnect, cybersecurity, lawful intercept, and government emergency telecommunications service within next generation networks. As networks transition to all-IP, PTSC will evaluate the impact of this transition and develop solutions and recommendations where necessary to facilitate and reflect this evolution.


  • PTSC is examining the standards/solutions implications for applying nationwide number portability in existing networks.
  • PTSC is working with the SIP Forum as part of the ATIS/SIP Forum IP-NNI Task Force to develop standards to address robocalling as well as anti-spoofing caller validation mitigation techniques.
  • PTSC develops and maintains standards that are required in support of National Security and Emergency Preparedness (NS/EP). This work is supported by various government agencies.
  • PTSC develops standards that are national variances of global specifications (e.g., IETF, ITU, and 3GPP). An example of this is ATIS-1000679, Interworking between Session Initiation Protocol (SIP) and ISDN User Part.
