This option provides eight additional T1 outputs. The outputs are
available at the OPTIONS I/O wire-wrap pins on the rear panel.
These outputs function the same as the standard T1 outputs.
TOD Output
The BesTime Ensemble Timing Generator provides the timing for
the TOD timing signal available at the RJ-45 connector, which
provides time code to devices compatible with NTP Type 4 or Cisco
ASCII format.
IRIG-B TOD Outputs

This option provides two additional TOD outputs in IRIG-B format.
The outputs are available at a BNC output module on the
OPTIONS I/O wire-wrap pins mounted on the rear panel.
The BesTime Ensemble Timing Generator provides the timing for
the TOD timing signal, which provides timing code to devices
compatible with IRIG-B.
1 PPS Output
The BesTime Ensemble Timing Generator provides the timing for
the 1 pulse-per-second timing signal available at the 1 PPS
connector, which can be used for application-specific
requirements. This signal is not squelched during an alarm.
