TSU LT Clock Sources
The TSU LT is operable from various clock sources
permitting it to perform properly in many different
applications. The network interface clocking options are set
by using the Network Configuration menu options. Three
clock source options are available:
• Network timing
• DTE timing
• Internal timing
The clocking option selected always designates the clock
source for transmission. Clocking necessary for receiving
data is always recovered from incoming data.
