Login
When first dialing in, the remote user is not required to enter a password if the
local user is already logged in.
Auto Answer Function
If Auto Answer mode is selected, the unit sends an automatic answering
command to the modem to answer incoming calls after a designated number of
rings. Otherwise, the modem will be configured not to answer.
Events
Events are defined in the AirLink Pro T1/E1 Rack Mount as Faults, Alarms,
Advisories, or Status Messages. These are the four levels of severity, with
Faults being the highest. The user may select a dial-out threshold as one of
these levels by issuing the SET DIAL LEVEL command, in much the same way
as selecting the event reporting level with the SET ALARM LEVEL command.
The Dial-out function will dial out when there is a condition at or above that
level. For proper operation, the dial-out severity level must be equal to or
greater than the event queuing level.
Dialout Function
During an event, the modem is directed to dial the telephone number(s) in the
configuration database and send a brief descriptive announcement. The
connection is then terminated. Up to two numbers can be selected; a primary
number that will always be dialed first, and a backup number in case the unit
cannot reach the primary number. Also, the unit will make repeated attempts
to dial if the first attempt is unsuccessful.
Operation
There are two user-configurable thresholds for alarms. An alarm threshold
establishes the point when the unit begins to dial-out. In addition, to prevent
excessive dialing in the presence of repetitive events, a dial holdoff time is
defined.
Alarm Holdoff Time (0 - 600 seconds; default = 10)
One or more events must persist between 0 - 600 seconds before a dial-out
attempt is made. When set to zero, the unit dials out immediately.
One qualifying event must be present although Alarm Holdoff does not require
the same condition for the entire interval.
