MASK
Controls the transmit signal
characteristics of the KML.7 module.
The displayed options depend on the
link interface hardware (with or
without CSU):
– When the link interface does not
include a CSU, the transmit signal
mask can be selected in accordance
with the transmit line length, to meet
DSX-1 requirements, as specified by
AT&T CB-119, or set for compliance
with FCC Rules Part 68A.
– When the link interface includes a
CSU, the transmit signal can be
attenuated by 7.5, 15, or 22.5 dB, to
meet the requirements of FCC Rules
Part 68A.
For link interfaces without CSU:
The following selections indicate the line
length in feet:
