Hardware Features Detailed Description
IRIG-B Timing Port
The router features a single IRIG-B timing port (see Figure 3-20), which provides serial formatted time
codes to an optional connected device. IRIG-B output provides standard time codes so timing devices
can correlate time information with network devices. The router-integrated GPS provides the time
information that is provided by this interface.
Note Currently not supported. This hardware feature will be supported in a future software release.
