Notes:
a. In the context of the Stratum 3 clock, an OFF-BOARD alarm occurs when
there is a DS1 facility problem; otherwise, the alarm is ON-BOARD
indicating that there is a fault in the Stratum 3 clock or in the connection
between the Stratum 3 clock and the PBX (Private Branch Exchange)
switch. If the Stratum 3 clock cannot be referenced, and therefore the
local oscillator on the TN780 Tone-Clock circuit pack must serve as the
reference instead, a Major alarm is raised. Otherwise, a Minor alarm is
raised.
b. This error can be caused by one of the following conditions:
1. One or both TOCs (Timing Output Cards) may have failed,
1. Run the Short Test Sequence. Refer to the appropriate test description and follow the recommended
procedures.
