Unit Alarm
Mask
MSK= 36 bytes Command or Query.
Set or return unit alarm masks in the form abcdefgxxxxxxxxxhijklmxxxxnopqrsxxxx, where:
Unit Alarm mask conditions, in form abcdefg, where:
a = Rx AGC Alarm***
b = Es/No Alarm***
c =
d = LNB
e = Reference alarm
f = Reserved
g = Rx decompression mismatch alarm***
xxxxxxxxx (9 spares)
PIIC1 Alarm mask conditions, in form hijklm, where:
h = Rx Buf PLL Alarm***
i = Rx Buf OverFlow Alarm***
j = rx Buf UnderFlow Alarm***
k = Ext Clk Act Alarm
l = Ext Clk In Range Alarm
m = input signal loss Alarm
n = Tx Symbol Clock PLL Alarm
xxx (3 spares)
PIIC2 Alarm mask conditions, in form nopqrs, where:
n = Rx Buf PLL Alarm***
o = Rx Buf OverFlow Alarm***
p = rx Buf UnderFlow Alarm***
q = Ext Clk Act Alarm
r = Ext Clk In Range Alarm
s = input signal loss Alarm
t = Tx Symbol Clock PLL Alarm
xxx (3 spares)
For PIIC1 And PIIC2
U = Uninstalled
X = Installed/Spare
Value of each mask:
*** indicates a 3 state mask where
0 = Unmasked Alarm (will not cause a redundant switch)
1 = Unmasked Fault (default, causes redundant switch)
2 = Masked (Ignore alarm or fault)
All other masks are 4 state masks where
0 = Unmasked Alarm (will not cause a redundant switch)
1 = Unmasked Fault (default, causes redundant switch)
2 = Masked (Ignore alarm or fault)
3 = Unmasked Fault Tx On (causes redundant switch but leaves Transmit output power on)
NOTE: Masks for alarms that are not applicable to various interface types (such as external clocks for OC3) are reserved as placeholders
and will not have any affect on operation.
