Table A. Parameter Definitions
PARAMETER
DEFINITION
aid
This parameter is the access identifier which is the equipment that the command affects. When
seen in a response, the <aid> is the equipment reporting the condition.
Note: Shelf types are defined as follows:
Master:
the shelf that is the communications interface for the system and contains the
highest-quality clocks in the system.
Expansion:
a shelf with no input cards, no clock cards, and is timed from the master shelf
via a ribbon cable (generally collocated with the master shelf).
Remote:
a shelf that contains timing input cards that use composite clock timing sig-
nals from the master or an expansion shelf (generally located distant from the
master shelf); communication port COM3 on the remote shelf must be con-
nected to communication port COM3 on the master shelf.
Without Remote Shelf:
direct a command to a particular shelf as follows:
<aid>
= Master shelf
E1-<aid>
= Expansion shelf #1
E2-<aid>
= Expansion shelf #2
E3-<aid>
= Expansion shelf #3
With Remote Shelf:
a maximum of two expansion shelves can be collocated with the master
shelf, and no expansion shelves can be timed from the remote shelf. To allow the master shelf
to communicate (send commands and receive responses) with the remote shelf, the master
shelf COM3 port and the remote shelf COM3 port must be connected. Direct a command to a
particular shelf as follows:
<aid>
= Master shelf
E1-<aid>
= Expansion shelf #1
E2-<aid>
= Expansion shelf #2
E3-<aid>
= Remote shelf (E3 identifies the remote shelf even if there are no
Expansion shelves).
almcde
This parameter is the alarm code which identifies the severity of the alarm. If multiple alarms
are reported, the value for almcde is the highest severity of those reported. Valid values for
<almcde> are:
*C
= critical alarm
**
= major alarm
*
= minor alarm
A
= event
atag
This parameter is the automatic message tag which is a decimal number with a maximum of 3
characters (1 through 999). It is assigned by the system to sequence and correlate automatic
messages.
baud
This parameter is the communications port baud rate. The baud rate for COM2 can only be
changed via jumper straps on the MIS card; ports 1 and 3 are software-configurable only.
clklevel
This parameter is the clock quality level assigned to the clocks in the shelf.
compri
This parameter is the priority of communication ports. Refer to the ED-COM command for valid
values.
