MODULES (USSI-2) > ALARM STATUS > ALARMS

Read security: 5

Displays an alarm condition on the ATLAS 550 unit.

SLIP	A rate mismatch exists between the DTE clock and the network-side
	clock (as set by DS0 assignment).
PLL	The USSI port is not able to lock onto the clock provided by the
	network interface.
ZERO	The DTE is sending an excessive number of consecutive zeroes to the
	network interface.
NO EXT CLK	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.
PKT EP ALM	A packet endpoint has detected missing or incorrect framing.

MODULES (USSI-2) > DTE STATUS

Read security: 5

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

MODULES (USSI-2) > DTE STATUS > PRT

Read security: 5

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

MODULES (USSI-2) > DTE STATUS > DTE STATUS

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

RTS	Request to send from DTE.
CTS	Clear to send to DTE.
DTR	Data terminal ready from DTE.
DSR	Data set ready to DTE.
DCD	Data carrier detect to DTE.
RI	Ring indicate to DTE.
TD	Transmit data from the DTE.
RD	Receive data toward the DTE.
EC	External clock present.

MODULES (USSI-2) > DATA RATE

Read security: 5

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.
