Notes:
a. Error Type 0:
run the short test sequence first. If every test passes, run the long test sequence. Refer to
each appropriate test’s description, and follow its recommended procedures.
b. Error Type 18: this port has been busied out by busyout port location.
c. Error Type 257: the VC DSP Port NPE Crosstalk test (#1103) failed.
d. Error Type 513: the VC DSP Port Local TDM Loopback test (#1104) failed. Run the long
test sequence.
e. Error Type 778 - 781: a critical hardware failure has been detected on the circuit pack.
Reset the port by busyout port location and reset port location. If the VC
Reset DSP test (#1106) passes, then the on-board circuitry is healthy. Retire the alarm with
test port location long clear.
f. Error Type 1025: the VC DSP port reported loss of framing on the Service Channel
between the VC and MMI circuit packs.
g. Error Type 1281: the VC DSP Port DSP Loopback test (#1105) failed.
h. Error Type 3840: the DSP corresponding to this port on the VC circuit pack reported a
firmware error. No action is required.

Descriptions and Error Codes
Investigate tests in the order presented below. Clearing Error Codes associated with one test
may also clear errors generated from other tests in the 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.
