Clock configuration
This feature is only available on specific Dialogic
®
Diva
®
xBRI and V-xPRI Media Boards. Clock synchronization
may be necessary, if one port of the Diva multiport Media Board is connected directly to the ISDN line and the
other ports are connected to the PBX, so that the clocks of the ports may drift. With the clock synchronization,
the ports configured as NT are synchronized with the TE ports on the same Diva Media Board.
To synchronize the ports, you have two options:
• You can synchronize the configured NT ports to one selected TE port. If you use this mode, either port 1 or 3
needs to be configured as TE. Select one of the TE ports under NT-ClockSync.
• In a specific monitoring configuration, NT port 2 is synchronized with TE port 1 and NT port 4 is
synchronized with TE port 3. In this configuration, port 2 and 4 must be NT and port 1 and 3 must be TE. If
you use such a configuration, select Monitor Mode under NT-ClockSync.
