Displays an alarm condition on the ATLAS 550 unit.

Shows the status of key DTE interface signals. An asterisk (*) indicates the presence of a signal and a 
hyphen (-) indicates no signal present.

Operating port number. There are 2 available interfaces on the Dual USSI Option Module.

The following signals are monitored (these options are read-only):

Displays the data rate at which each USSI port is currently operating. A port’s data rate is determined by 
the number of DS0s assigned to it and the rate per DS0 associated with the active maps.

A rate mismatch exists between the DTE clock and the network-side 
clock (as set by DS0 assignment).

The USSI port is not able to lock onto the clock provided by the 
network interface.

The DTE is sending an excessive number of consecutive zeroes to the 
network interface.

The DTE is not providing an external transmit clock. This alarm 
displays only if the USSI port is configured to get its transmit clock 
from the DTE.

A packet endpoint has detected missing or incorrect framing.

Request to send from DTE.

Clear to send to DTE.

Data terminal ready from DTE.

Data set ready to DTE.

Data carrier detect to DTE.

Ring indicate to DTE.

Transmit data from the DTE.

Receive data toward the DTE.

External clock present.
