labels you will be working with on the NIC. Record the loop’s HSL port labels
on the NIC for use in a following step or steps in this procedure. Record the
loop’s HSL port labels on the NIC for use in a following step or steps in this
procedure.
7. Determine which HSL port label the cable is connected to on the frame. The
port number indicator is in the rightmost four characters of word 5 in the
SRC. The port number indicator in word 5 identifies either the
″
x0
″
or
″
x1
″
HSL port label on the frame. Use the port number indicator and the following
table to determine if you are working with the
″
x0
″
port or the
″
x1
″
port label.
Record the port location label you will be working with on the “Appendix I.
HSL Cable Location Form” on page 971 as the
″
