| All written standards that govern Frame Relay implementations are American National Standards Institute (ANSI), International Telecommunication Union Telecommunication Standardization Sector (ITU-T), or Frame Relay Forum (FRF) standards. Although ANSI and ITU-T standards are based on the ISDN architecture, the FRF documents address implementation issues, ensuring the interoperability of multivendor networks. Table 14-2 summarizes some of the ANSI and ITU-T standards governing Frame Relay. Table 14-2. ANSI and ITU-T Standards Governing Frame RelaySubject | ANSI | ITU-T |

The FRF (www.frforum.com) was created to develop Frame Relay technologies, to improve the existing standards, and to facilitate multivendor inter-operability. The FRF's formal documents are called Implementation Agreements (IAs). Table 14-3 shows the current issued agreements. Table 14-3.
