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:
Router# show controllers pos1/1
Interface POS1/1
Hardware is OC48 POS
