ZSX1-TKN-LINE-STATE
indicates the line state. This token is described in Section 4 of the SNAX/XF
Management Programming Manual.
ZSX1-TKN-TRACE-STATE
indicates the trace state. This token is described in Section 4 of the SNAX/XF
Management Programming Manual.
ZSX1-TKN-ENV-RESID
is the protocol-level ID. This token is described in Section 4 of the SNAX/XF

Cause. The operator has brought down a line, or an error has occurred that brought it
down. This message is generated by the level-3 protocol. For X.21, this event message
occurs when an attempt to disconnect a switched line fails.
Effect. The line is inoperative; all devices attached to the line are disconnected. Note
that, on switched lines, this event is generated even though the message is typically a
normal event on a switched line not requiring the attention of a console operator. If the
SCF line attribute SWOPMSG is set to OFF, this event is not generated.
Recovery. Abort the line, and then restart it. Refer to the Guardian Procedure Errors
and Messages Manual for further information about the file-system error.
