Configuring parameters
The MMI has been designed with default settings so that no configuration is
necessary. However, it can be configured to suit a specific environment.
Set Time
Before configuring the MMI, login to the system and enter the current time.
Do this by typing in the Set Time (S T) command set. The MMI will then
display the time it has registered. Enter a new time or press “Enter” to leave
it unchanged. The time is entered in the “hh:mm:ss” military time format.
Set Date
The current date must be set. Do this by typing in the Set Date (S D) command
set. MMI will then display the date it has registered. Enter a new date or press
“Enter” to leave it unchanged. The date is entered in the “mm/dd/yy” format.
Alarm parameters
The Set Alarm (S A) command set establishes the parameters by which an
alarm is activated, and its duration. There are three alarm activation levels:
• Alarm Level 0 (AL0) consists of activity with an error threshold below
the AL1 setting. This is a satisfactory condition and no alarm is activated.
• Alarm Level 1 (AL1) consists of activity with an error threshold above
the AL1 setting but below AL2 setting. This is a minor unsatisfactory
condition. In this situation, the external alarm hardware will be activated
by closing the normally open contact, the RED ALARM LED on the
faceplate will light, and an alarm message will be created in the alarm log
and the MMI terminal.
• Alarm Level 2 (AL2) consists of activity with an error threshold above
the AL2 setting. This is an unsatisfactory condition. In this situation, the
external alarm hardware will be activated by closing the normally open
contact, the RED ALARM LED on the faceplate will light, an alarm
message will be created in the alarm log and the MMI terminal, the
lineside T1 card will enter line processing mode, and a yellow alarm
message will be sent to the CPE/CSU. Line processing will send the
CS 1000S, CS 1000M, and Meridian 1 either all “on-hook” or all
“off-hook” signals, depending on the dip switch setting of the card.
