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 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.
