o
At bottom of display: Correction in progress due to more than 1/4
bit phase change.*
P
Displayed momentarily immediately after power-up if input card is
T1 type (54511) or CC/5 MHz/10 MHz (54513-3, -4, -5).
E
Displayed momentarily immediately after power-up if input card is
E1 type (54512-5).
NOTE:
For the clock card to detect an E1 type of input card, the input card itself must be
present. Without an E1 input card physically plugged in, the clock card will default to run
the T1 type of operation.
E, then 2
Displayed momentarily immediately after power-up if clock card
detects a 2.048 MHz square wave input card (54512-3).
g
Displayed when unit has successfully entered GPS in Known
mode. This is the
normal
steady-state indication. (Not to be
confused with DS1/E1 error condition ‘9'.)
g.
Displayed when unit has entered GPS in Position Average mode.
This is the
non
steady-state indication.
L
Acquiring input reference.
H HOLD
state.*
A
Synthesizer control in top 25% of range.
b
Synthesizer control in bottom 25% of range.
=
Primary input in use.*
||
Secondary input in use.*
c
Standalone state: S2 switch in TEST position.
r
Free running state: No input is present and no tracking has
occurred. Happens on power-up if TEST pushbutton is not being
pressed and no good DS1/E1 inputs are present.
b. Error conditions when card goes into HOLD state*:
2
Excess BPVs; does not cause hold.
3 LOF
synchronization.
4 AIS.
5
Input in Yellow Alarm state.
6
Excessive frame bit errors (FBEs); does not cause hold.
