The following DS1 facility options are sent to the TN574 DS1 CONV circuit pack:
Framing Mode, Line Coding and DS1 CONV-1 and DS1 CONV-2 Line
Compensation.
The following DS1 facility options are sent to the TN1654 DS1 CONV circuit pack:
Line Coding and DS1 CONV-1 and DS1 CONV-2 Line Compensation (T1 only).
These option fields are given in the fiber link administration screen.
Near-end External Loopback Test (#799)
This test is destructive
This test starts at the DS1 CONV circuit pack whose equipment location was
entered and traverses over the specified facility and loops back at the manually
hard-wired external loopback device. Depending on the type of physical
connectivity of the DS1 facility, special tools, cables or connectors may be
required to make the hard-wired loopbacks.
To isolate a problem, set the loopback first at the loopback point LB 1, and then
at the loopback point LB 2, see Figure 9-31
and
Figure 9-28.
Place the
loopbacks at as many points as your CSU capabilities will allow. Hard-wired
loopbacks at the far end are not desirable, because the equalization level
adjustments may cause problems.
