Notes:
a. This port has been busied out by the busyout port PCSSpp 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 PCSSpp and reset port PCSSpp commands. If
the VC Reset DSP Test (#1106) passes, then the on-board circuitry is
healthy. Retire the alarm with the test port PCSSpp 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.
