Pstn harmonization tunneling pstn signals

SCN - 2(Switched

Circuit Network)

H.323 over IP network

SCN - 1(Switched Circuit Network)

PSTN HarmonizationTunneling PSTN Signals

  • SCN (Switched Circuit Network) will exist for many years- SS7 signaling transport over IP will be very useful for coexistence

  • Enables H.323 as a “transport layer” between telephony domains

  • Enables signaling between SCN networks over H.323

    • QSIG – Annex M.1

    • ISUP – Annex M.2

    • DSS1 – Annex M.3
