Clear the RCVR-MISS Alarm
Step 1 Ensure that the device attached to the DS-1 port is operational.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454.
Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.
Step 2 If the attachment is good, verify that the cabling is securely connected.
Step 3 If the cabling is good, verify that the pinouts are correct.
Step 4 If the pinouts are correct, replace the receive cable.
Step 5 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447 in order to report a service-affecting (SA)

SONET Logical Object: RPRIF
The Reserved Bandwidth Exceeds Link Rate on Ringlet Zero alarm is raised by an ML-1000 card if the
sum the of reserved bandwidth configured on each station of ringlet 0 is greater then the link rate (circuit
bandwidth). The alarm clears when the sum of the reserved bandwidth on each station falls below the
link rate. In the case of SW-LCAS or LCAS circuits, the link rate is the working link rate, which will
change when members are removed
RSV-RT-EXCD-RINGLET0 does not suppress any alarms, but it is suppressed by the “RPR-PASSTHR”
alarm on page 2-209.
