FTB-700G/800 Series
Clock
Ext Clock In
Note:
Available when the
Clock Mode
is set to
External
.
Allows to set the external clock for test synchronization.
Interface Type
allows the selection of the clock interface:
DS1
(default),
E1
,
2MHz
, or
1PPS
.
1PPS
is automatically selected for
Dual Test Set
in
One-Way Latency
measurement mode.
Ext Clock In
on a green background indicates that a valid clock is
received on the
EXT CLK
port.
LOS
on a red background indicates that the clock is not valid on the
EXT CLK
port.
Termination
mode specifies how the NetBlazer is connected to the
synchronization signal. The
Termination
mode is set to
TERM
for 2MHz
and configurable for DS1 and E1.
For DS1:
TERM
provides an input that terminates the DS1 signal.
DSX-MON
provides high-input impedance and compensation for
resistive loss. This setting is useful for monitoring DS1 signals at
DSX monitor points, which are resistor-isolated.
BRIDGE
provides high-input impedance for bridging lines that are
already terminated. This setting is useful for bridging directly
across copper cable pairs.
