Alarms Number of suspect bit patterns found in several consecutive frames
snmp trap link-status State of SNMP link status processing for the controller:
enabled or disabled
alarms used for operational status calculation Types of defects that the
router uses to determine the operational status of the interface at the path
layer
defect trigger soaking delay Time that the router waits to set an alarm
when the router records a defect at the path layer
c2 byte Setting of path signal byte: set by upper interface type (automatic
setting) or configured value
Operational Status Physical state of this layer: up, down, or lowerLayerDown
time since last status change Time since the line module was rebooted
Framing Type of framing configured for the controller:
c-bit parity framing (for T3 interfaces)
M23 multiplexer framing (for T3 interfaces)
crc4 Cyclic redundancy check (for E1 interfaces)
no-crc4 No cyclic redundancy check (for E1 interfaces)
esf Extended superframe (for T1 interfaces)
sf Superframe (for T1 interfaces)
Line Code Type of line coding the router assigned to the controller: B8ZS
or AMI
Clock source Type of clock source configured for the channel:
module Internal clock is from the line module itself
chassis Internal clock is from the configured router clock
J1 transmit trace message Trace message sent to the remote device
J1 expected trace message Trace message expected from the remote device
J1 received trace message Trace message received from the remote device
