    Media Gateway 3500 Clock Synchronization The Media Gateway 3500 Media Gateway can operate in either Non-Synchronized or Synchronized mode. 4.5.1 Clock Synchronization for PSTN Interfaces When connecting the gateway to PSTN network, the clock synchronization methods that should be applied for the PSTN trunks must be reviewed. Typically, the gateway can receive the synchronization clock from several sources as BITS (Building Integrated Timing Source), SETS (SDH Equipment Timing Source) or from regular E1/T1 trunks.

  • Page 61: Connections For The Synchronized Mode

    4.5.2 Connections for the Synchronized Mode In synchronized mode, the Media Gateway 3500 operates in synchronization with the PSTN equipment attached to the PSTN interfaces. It derives the synchronization timing from one of the E1 / T1 / J1 trunks and distributes the timing to all other synchronous interfaces in the system according to Bellcore GR-1244-CORE line-timing scheme.
