DS1 Circuit Pack
Issue 5 October 2002 777555-233-506
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).
INTEGRATED CSU OPTIONS
Receive ALBO (Receive Automatic Line
Build-Out)
This field increases the strength of incoming signals by a fixed amount to
compensate for line losses.
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.
Valid entries Usage
y/n
Enter n. Consult your Avaya representative if you think you
may want to use these reports.
Valid entries Usage
26db
To set this field correctly, you should measure the signal loss
on this specific facility. However, you may enter
26db for
most applications.
36db is occasionally appropriate, mainly
on campus networks that don’t conform to public telephone
network standards.
