T1/E1 Port Status]
Default: Unconfig-
ured
Range: NA
Format: Alphabetical
Indicates the status of the input T1BITS or E1ETSI
clock source connected to the external clock con-
nector on the baclup Stratum 3–4 module.
Unconfigured
Indicates T1BITS or E1ETSI clock source is not con-
nected to the external clock connector.
noalarm
Indicates the connected T1BITS or E1ETSI clock
source is functioning properly.
portAIS
Indicates the connected T1BITS or E1ETSI clock
source is reporting an alarm indication signal.
portLOF
Indicates the connected T1BITS or E1ETSI clock
source is reporting a loss of frame.
portLOS
Indicates the connected T1BITS or E1ETSI clock
source is reporting a loss of signal.
portFOS
Indicates the connected T1BITS or E1ETSI clock
source is reporting a frequency offset.
Accuracy
Default: Stratum3
Range: NA
Format: Alphabetical
Indicates the precision of the clock circuitry when it
locks to the selected external synchronization
source (CompositeClock, CompositeClock-
DS0A, T1BITS, and E1ETSI, selected in the Syn-
chronization Source field).
Stratum3
Indicates the timing source has a Stratum3 level of
precision.
Stratum4
Indicates the timing source has a Stratum4 level of
precision.
On Reference Clock
Failure Go To
Default: Freerun
Range: NA
Format: Alphabetical
Indicates what timing source is used when the
selected synchronization source fails, except
LineTiming. If LineTiming is selected, both the
Primary Line Source and Secondary Line Source
clocks must fail before reverting to this clock.
Freerun
Indicates that the module switches to freerun if the
selected synchronization source fails.
