Clk-Ref Option Descriptions
Option Description
Ext-1MHz The VersaMux uses either a 1-MHz Bipolar, a 1-MHz TTL, or a 1-MHz RS-422, signal
from the External Clock Input to generate the System Timing Clock Reference.
Ext-5MHz The VersaMux uses either a 5-MHz Bipolar, a 5-MHz TTL, or a 5-MHz RS-422, signal
from the External Clock Input to generate the System Timing Clock Reference.
Ext-10MHz The VersaMux uses either a 10-MHz Bipolar, a 10-MHz TTL, or a 10-MHz RS-422, signal
from the External Clock Input to generate the System Timing Clock Reference.
Aggregate The VersaMux uses the recovered timing signal from the Aggregate interface to
generate the System Timing Clock Reference.
Port-1 The VersaMux uses the recovered timing signal from the Port 1 interface to generate
the System Timing Clock Reference.
