Field descriptions
SPE
Switch Process Element (SPE) identifier: 1A or 1B
MODE
SPE modes are different for simplex systems than for
duplicated systems. See ‘‘SPE Modes’’ section that follows.
SELECT SWITCH
SPE select switch position:
■ auto: the switch is in the middle position and
automatically switches SPE depending upon conditions
■ spe-a: spe-a position
■ spe-b: spe-b position
■ <blank> always appears for the 1A and 1B SPE in a
simplex system. In a system with High or Critical
Reliability, blank implies a hardware problem with the
Duplication Interface circuit pack.
PE ALARMS -
MAJOR
Number of Major alarms associated with the SPE complex
that affect the fault severity level of this SPE. If the system is
simplex system, then the 1B SPE always shows blank.
SPE ALARMS -
MINOR
Number of Minor alarms associated with the SPE complex
that affect the fault severity level of this SPE. If the system is
simplex system, then the 1B SPE always shows blank.
TONE/CLOCK
Location of the tone-clock circuit pack. Valid locations are 1A,
1B, 2A, 2B, 3A, and 3B.
SERVICE STATE
■ in: Tone-Clock is installed and is in-service
■ out: Tone-Clock failed certain maintenance tests and
has been removed from service
■ <blank> In simplex systems there is no B-carrier
Tone-Clock, and this field displays blank.
SYSTEM CLOCK
Shows which Tone-Clock supplies the system clock for the
cabinet displayed:
■ active: Tone-Clock active and supplying system clock
■ standby: Tone-Clock is standby and ready to supply
the system clock for this cabinet if the active clock fails.
■ down: Tone-Clock failed some maintenance activity and
cannot supply the system clock for this cabinet.
■ unavail: EPN is currently down
■ <blank> If simplex, then the 1B Tone-Clock for the PPN
displays blank; if no EPN, then both the 1A and 1B
Tone-Clock for this EPN display blank.
