*Note:
Use the MASTER clock for EXTERNAL clock input. This clock input
should equal the data rate unless the Asymmetrical Loop Timing Option (ASLT)
is available. The ASLT option allows selection of different clock rates that vary
from the digital data rate. Refer to the Utility/Modem Type/Modem Options
menu for the ASLT option information.
