SPE-SELE (SPE Select Switch)
The SPE Select Switch MO monitors the position of the SPE Select switches
located on the front of each UN330B Duplication Interface board. Each switch
may be in one of three possible positions: Auto, A selected, B selected. Both
switches, one on the active Duplication Interface board and one on the standby,

No alarm is raised.
■
If one SPE Select switch is in the AUTO position and one selecting either A
or B carrier as active, or one switch selects A and the other selects B, the
boards default to handling the selection of which carrier is active as if both
switches were in the AUTO position. A WARNING alarm appears after one

hour. The alarm is resolved 5 minutes after the switches are returned to

■
If both switches select either A carrier or B carrier active, then the
Duplication Interface boards will force that carrier active (irrespective of
state-of-health) and the red Override LED is lit. A MAJOR alarm is raised
by SPE-SELE if the switches remain in these positions for more than 6
hours. The alarm is resolved within 5 minutes of the switches being
returned to AUTO.
