Troubleshooting the POS Uplink Card Installation

STS Path Loss-of-Pointer (LOP)

STS Path Alarm Indication Signal (AIS)

STS Path Remote Defect Indication (RDI)

B1 Bit Error Rate (BER) threshold crossing alarm (b1-tca)

B2 BER threshold crossing alarm (b2-tca)

B3 BER threshold crossing alarm (b3-tca)

Line Bit Interleave Parity (LBIP) BER in excess of signal degrade threshold (sd-ber)

LBIP BER in excess of signal failure threshold (sf-ber)

At any time the status of the SONET/SDH alarm and signal events can be examined using the show controllers command, as shown in the following example:
