Local indications –
Cause There are two possible reasons:
1. Either the port is intentionally not in use, and therefore is provisioned “Not
Monitored”, but mistakenly an input signal is applied (due to erroneous
routing of intermediate cabling for example), or
2. although an input signal is applied, the port is mistakenly provisioned “Not
Monitored”.
Actions Put the X.21 interface port “Monitored”, or check the cabling (and re-arrange
if necessary).
