The T1/E1 Frame Generator module produces the timing signals to create DS1, E1, and Composite Clock outputs. The DS1 (ESF only) and E1 signals can include Synchronization Status Messages (SSM), if required. The Clock Bypass function allows the module to continue generating normal output signals when both clock modules are in warm-up mode or when the clocks have been removed from the unit. The module's LEDs are described in the following table and the screen's fields are described in the table below.
