SC EIM in slot one which provides hardwired alarm inputs and outputs, remote ACO activation, and timing reference inputs (BITS), cannot be found .

SC EIM in slot 18 which provides backplane bus termination, Telnet connection to the node, and shelf addressing, has been physically pulled from the backplane.

Input signal strength is degraded. Possibly a fiber problem or transmitter.

NMIC unable to download software successfully to the NE.

SONET sync message (S1 byte) changed.

Timing reference that the network element clocks off of has failed.

T1 Loopback Pseudo Random Pattern. Indicates a loopback condition has been initiated by a user.

DSX1 Alarm: Remote Alarm Indication. Indicates a problem at the CPE transmitter.

Buses are probably not functioning properly because the Bus Terminating EIM (B- TEIM) in slot 18 at the rear of the shelf or the SC in slot 1 has been physically removed from the backplane.

Buses are probably not functioning properly because the Bus Terminating EIM (B- TEIM) in slot 18 at the rear of the shelf or the SC in slot 18 has been physically removed from the backplane.

Check fiber path for damage or bends and check attenuation and transmitter output.

Check FTP connection and NE status.

No suggestions.

Retrieve timing source information and check reference input (BITS, 622-RIC, 155- CRS).

Check for troubleshooting activity by other users and release loopback if necessary.

Check card and output level of CPE equipment. Replace as needed per local practices.
