Test Setup - Test Configurator, Timer, and System
126 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.
Ter mination mode specifies how the NetBlazer is connected to the
synchronization signal. The Ter mination 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.
