Alarm Condition
What It Indicates What To Do
AIS at Network 1 An Alarm Indication Signal
(AIS) is being received by
the interface. AIS is an
unframed, all ones signal.
For the network interface, report
the problem to your T1 service
provider.
AIS at DSX-1 For the DSX-1 interface,
the attached DTE is
transmitting an AIS.
For the DSX-1 interface, check
the DTE attached to the
interface.
EER at Network 1 The error rate of the
received network signal
exceeds the currently
configured threshold. This
condition only occurs if the
network interface is
configured for ESF framing.
This condition clears when
the error rate falls below the
threshold value, which may
take up to 15 minutes.

securely attached at the
network interface.
H Contact your network provider.
