SIG MON
The Signaling Monitor feature works with the user card alarm system to detect excessive
signaling bit transitions. The system will generate alarms if the number of transitions of any
signaling bit in transmit or receive direction for an active port exceeds 255 in any four second
interval. The options are off and on, and they are toggled by pressing “g” (siGmon command)
in the Test Screen.
TEST
The Test parameter shows if the port is in test mode or not. Inactive ports and ports that are
assigned to inactive WANs will show a test status of n/a. The test status options for active
ports are off and on.
Tx ABCD
The Transmit ABCD setting allows the user to either monitor the status of the ABCD signaling
bits being transmitted towards the network or set a specific ABCD pattern for testing the
transmit side of the circuit. The options for this field are mon (monitor) or set. Choosing set
will bring up a four digit field for users to input the ABCD pattern they want to transmit. Any
four-digit combination of ones and zeros is acceptable for this setting.
