DS3 I/O INTFC cannot recover framing
from incoming DS3 signal or there is no
input signal. Is DS3 AIS Detect Alarm on?
B
Yes, troubleshoot upstream radios and
external MUX equipment.
No, check input signal. If input signal is
OK, replace DS3 I/O INTFC. If not,
troubleshoot external MUX equipment.
DS3 input to DS3 I/O INTFC has exceeded
provisioned BER threshold (high error
condition).Troubleshoot external MUX
equipment.
AIS (blue signal), inserted at MUX (external
to the radio) has been detected on XMT input
to DS3 I/O INTFC.
Troubleshoot external MUX equipment.
OC3/STM-1 INTFC cannot recover framing from
incoming OC3/STM-1 signal or there is no optical
input signal.
Is OC3/STM-1 AIS-L Detect alarm on?
Yes, troubleshoot upstream radios and external
MUX equipment.
No, check optical input signal. If optical input
signal is OK, replace OC3/STM-1 I/O INTFC. If not,
troubleshoot external MUX equipment.
AIS (blue signal), inserted at MUX (external to the
radio) has been detected on OC3/STM-1 input to
OC3/STM-1 I/O INTFC.
Troubleshoot external MUX equipment.
OC3/STM-1 input to OC3/STM-1 I/O INTFC has
exceeded provisioned BER threshold (high error
condition).
Troubleshoot external MUX equipment.
