Clock
LOPPS-L, available with 1PPS, on a green background indicates that a
valid clock is received.
Connector either indicates the connector type used for the clock or
allows the selection of Bantam or RJ48C when the BNC connector is
used by the test application. The unit connector blue LED used for Ext
Clock In is flashing.
Ter mination mode specifies how the unit 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.
For E1:
TERM provides an input that terminates the E1 signal.
MON provides high-input impedance and compensation for
resistive loss. This setting is useful for monitoring E1 signals at
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.
Line Coding allows the selection of the interface line coding.
For DS1: AMI and B8ZS (default).
For E1: AMI and HDB3 (default).
