Origin Tags

The origin tags identify the source of all Write entries and how an event occurred. The exact meaning is dependent
on the type of event and the unit reporting the event. A Write entry changes a system parameter or an option
setting, but does not affect circuit status changes, such as alarms.

Description
Event was initiated from the RS-232 craft port located on the front panel of the H2TU-C.
Event was initiated from the MODE and/or LBK pushbutton on the front panel of the H2TU-C.
Event was initiated from a host management unit, such as an HMU-319, that sent a command over
the management bus on the H2TU-C shelf backplane.
This generic origin tag can only occur when viewing the Event Log screen at the remote unit. It is a
general indication that the event was initiated at the line unit. The Event Log screen must then be
viewed at the line unit (through an Rlogon command) for more specific origin information.
Event was initiated from the LBK pushbutton on the front panel of the H2TU-R.
Event was initiated from the RS-232 craft port located on the front panel of the H2TU-R.
Event was initiated by a non-intrusive TL1 command embedded in the FDL of the ESF DS1 signal
received by the HDSL2 circuit.
Event was initiated by an intrusive command in the DS1 payload received by the HDSL2 circuit.
This generic origin tag can only occur when viewing the Event Log screen at the line unit. It is a general
indication that the event was initiated at the remote unit. The Event Log screen must then be viewed
at the remote unit (through an Rlogon command) for more specific origin information.
Implies that the loopback command was initiated at the remote unit by the front-panel pushbutton,
craft port, or in the remote unit's DS1 input payload. A loopback initiated from a terminal would have
a Remote Unit tag if the initiating terminal is in a remote logon session.
Implies that the loopback command was initiated at the line unit by the front-panel pushbuttons, craft
port, or in the line unit's DSX-1 input payload.
Indicates that the alarm occurred at the remote unit.
Indicates that the alarm occurred at the line unit. LOSW, SHORT, GND, and OPEN are always tagged
as line unit alarms.
