Clock Synchronization
Signal Analysis
Output Presence: Indicates the presence of a signal at the output
interface/port (green) or not (gray).
Alarm Analysis
LOC (Loss Of Clock): Indicates if the module is able to synchronize
with the selected clock mode and generates a valid synchronization
signal at the AUX output port (green) or not (red; no signal is generated
at the AUX output port).
RX
Note: RX clock configuration is only possible when the TX clock is set to None.
Configuration: Allows the selection and configuration of the input clock.
This clock will be used for test synchronization if External clock has been
selected during test setup.
Interface Type: Allows the configuration of the clock that will be
received. First select the Interface Type then, the other parameters will
become accessible for configuration. Choices are: None, DS1, E1, and
2 MHz.
Termination Mode: Specifies how the unit is connected to the
synchronization signal. Choices are:
For DS1:
Term: Provides an input that terminates the DS1 signal.
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.
