Notes:
a. This port has been busied out by the busyout port UUCSSpp command.
b. The VC DSP Port NPE Crosstalk test (#1103) failed.
c. The VC DSP Port Local TDM Loopback test (#1104) failed. Run the long
test sequence.
d. A critical hardware failure has been detected on the circuit pack. Reset the
port by the busyout port UUCSSpp and reset port UUCSSpp
commands. If the VC Reset DSP test (#1106) passes, then the on-board
circuitry is healthy. Retire the alarm with the test port UUCSSpp long
clear command.
e. The VC DSP port reported loss of framing on the Service Channel between
the VC and MMI circuit packs.
f. The VC DSP Port DSP Loopback test (#1105) failed.
g. The DSP corresponding to this port on the VC circuit pack reported a
firmware error. No action is required.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the table below. For example,
by clearing error codes associated with the DSP NPE Crosstalk test (#1103), you
may also clear errors generated from other tests in the testing sequence.
DSP NPE Crosstalk Test (#1103)
This test is destructive.
The NPE Crosstalk test verifies that this port’s NPE channel talks on the selected
time slot and never crosses over to time slots reserved for other connections. If
the NPE is not working correctly, 1-way and noisy connections may be observed.
This test is part of the port’s long test sequence and takes approximately 20 to 30
seconds to complete.
