7.5.3 DETERMINING THE ALERT/ALARM STATUS
You can determine the overall alarm and alert status of an IMUX 2000 multiplexer by issuing a
STATUS? command to its TERM or DI-A module. For example, to determine the overall status of a
terminal multiplexer, issue a command of the form:
<Address>:TERM:STATUS?:;
The response to this command shows the status of the multiplexer's E1 interface and indicate whether
any channel modules are in an alarm or alert state. Similarly, to determine the overall status of a
drop/insert multiplexer, issue a command of the form:
<Address>:DI-A:STATUS?:;
The response to this command shows the status of the A-direction E1 interface - that is, the E1
interface on the DI-A module.
To determine the status of the E1 interface on the DI-B module in a drop/insert multiplexer, issue a
command of the form:
<Address>:DI-B:STATUS?:;
The response to this command shows the status of the B-direction E1 interface and indicates whether
there is an alert or alarm condition in the shelf.
If an IMUX 2000 multiplexer is not in an alarm or alert state, then it responds as follows to a
STATUS? command issued to its TERM or DI-A module:
*OK
FROM NET ADDRESS=XX
SHELF NORMAL;
This response indicates that no power, timing, or E1 alarms or alerts are detected, the ACO switch is
not on, and that no channel module on either the Main or Expansion shelf (if provided) is in an alarm
or alert state. This "SHELF NORMAL" response may also include the line "RECEIVING ALL
ONES" if the far end multiplexer is idle.
If, however, the queried multiplexer is in an alarm or alert state, then it generates a response with the
following format:
*OK
FROM NET ADDRESS=XX
>>>ALARM (or ALERT) AT SHELF<<<
(message describing the alarm or alert condition[s])
