Send ANSI-T1.403 One-Second Performance 
Reports
This field selects whether your DS1 circuit pack will send error reports to the 
far-end switch. These reports are useful for network management, and are sent at 
1-second intervals when enabled. This field appears only if the Framing Mode 
field is 
esf
. It is used only with circuit packs that have an integrated channel 
service unit (CSU).
Far-end CSU Address
This field, which, appears only if the Framing Mode field is 
esf

Transmit LBO (Transmit Line Build-Out)
This field reduces the outgoing signal strength by a fixed amount. The appropriate 
level of loss depends on the distance between your switch (measured by cable 
length from the smart jack) and the nearest repeater. Where another switch is at 
the end of the circuit, as in campus environments, use the cable length between the 
2 switches to select the appropriate setting from the table below. This field appears 
if the Near-end CSU Type field is 
integrated
.
