SIGNAL LOSS
If ALARM is displayed, no physical signal is present on the DSX port. This stat is only available if a
T1/DSX Network Interface Module is installed.
TELCO TEST
This field will indicate when the unit is in a loopback test initiated by the Telco. This stat is only available
if a T1/DSX Network Interface Module is installed.
AIS ALARM
If ALARM is displayed, unframed all ones were received by the DSX-1 port one or more times during the
given interval. This indicates that the T1 is out of service. This stat is only available if a T1/DSX Network
Interface Module is installed.
RED ALARM
If ALARM is displayed, a loss of frame synchronization occurred on the DSX-1 port one or more times
during the given interval. This stat is only available if a T1/DSX Network Interface Module is installed.
YELLOW ALARM
If ALARM is displayed, the far end of the DSX-1 was out of frame sync one or more times during the given
interval. This stat is only available if a T1/DSX Network Interface Module is installed.
PLL ALARM
ALARM displayed in this field usually signifies that both ends of the DSX-1circuit are set to provide
timing. This stat is only available if a T1/DSX Network Interface Module is installed.
PATH CODE
Number of path code violations received by the DSX-1 port. Path code violations include frame bit errors
for D4 framing and superframes with CRC errors for ESF framing. This stat is only available if a T1/DSX
Network Interface Module is installed.
LINE CODE
Number of line code violations received by the DSX-1 port. Line code violations include BPVs that are not
part of B8ZS code or excess zero violations. This stat is only available if a T1/DSX Network Interface
Module is installed.
VIEW STATISTICS > DSX PORT > DAYS
The definitions for the DSX PORT > DAYS statistics are identical to the DSX PORT > INTERVALS statistics.
The day view provides historical information for the last seven days (not including the current day).
VIEW STATISTICS > DBU PORT > INTERVALS > RX FRAMES
Number of frames received by the DBU port. This stat is only available if a DBU module is installed.
