Clock
Ext Clock In
Note:
Available when the
Clock Mode
is set to
External
.
Allows setting the external clock for test synchronization.
Interface Type
allows the selection of the clock interface:
DS1
(default),
E1
,
2MHz
(default when DS1 is not supported), 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.
LOS
on a red background indicates that the received clock is not valid.
Connector
, available on 8870/8880, either indicates that the BNC
connector type is used for the clock or on 8880 allows the selection of
Bantam
or
RJ48C
when the BNC connector is used by the test
application. The module connector blue LED used for Ext Clock In is
flashing.
Termination
mode specifies how the module 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.
