MODULES (USSI-2) > ALARM STATUS > ALARMS
Read security: 5
Displays an alarm condition on the ATLAS 550 unit.
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):
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.
S
LIP A rate mismatch exists between the DTE clock and the network-side
clock (as set by DS0 assignment).
P
LL The USSI port is not able to lock onto the clock provided by the
network interface.
Z
ERO The DTE is sending an excessive number of consecutive zeroes to the
network interface.
N
O 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.
P
KT EP ALM A packet endpoint has detected missing or incorrect framing.
R
TS Request to send from DTE.
C
TS Clear to send to DTE.
D
TR Data terminal ready from DTE.
D
SR Data set ready to DTE.
D
CD 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.
