Site Name
The site name identifies the role or location of the specified AirLink Pro T1/E1
Rack Mount. In the previous example, “Sunnyvale 2” is the site name. This
parameter is optional and can be any convenient description up to 60
alphanumeric characters.
When using the Dial Out Alarm feature, it is important to have a descriptive
name because the Site Name is part of the specific alarm report.
It might also be useful to put AU in a site name when an Access Unit is at the
site.
T1/E1 DTE Input Loss
Indicates whether the T1/E1 signal on the cable from the DTE has been lost.
The T1/E1 input loss detector monitors the T1 or E1 input signal from the DTE
and declares DTE input loss when it detects 175 ±75 continuous zeros in the T1 or
E1 bit stream.
When the controller detects T1/E1 input signal loss, it instructs the transmitter
to send all ones toward the radio, updates the status reporting database, and
turns on the Signal Loss indicators in the AirLink Pro T1/E1 Rack Mount. In the
absence of a T1/E1 input signal, the unit switches to internal clocking.
Radio Synchronization Loss
Indicates whether radio synchronization has been lost. An action similar to
the DTE input loss occurs for radio synchronziation loss. See the previous
paragraph referring to the controller detecting signal loss.
Burst Synchronization Loss
Indicates whether burst synchronization has been lost. An action similar to the
DTE input loss occurs for burst synchronziation loss. See the paragraph referring
to the controller detecting signal loss under the heading DTE Input Loss.
Test in Progress
When a test is active, query status identifies the test by name. Only one test
can be run at a time. If you attempt to start up a second test while a test is
running, the system terminates the first test and inserts an event message in the
event queue.
