Set Time
Before you begin to configure your MMI, login to the system and verify the
current time. Do this by entering the Set Time (S T) command. The
MMI then displays the time it has registered. Enter a new time or hit Enter
to leave it unchanged. The time is entered in the "hh:mm:ss," 24-hour, or
military, format.
Set Date
Also, verify the current date. Do this by entering the Set Date (S D)
command. The MMI then displays the date it has registered. Enter a new date
or hit Enter to leave it unchanged. The date is entered in the "mm/dd/yy"
format.
Set Alarm
The Set Alarm (S A) command establishes the parameters by which
an alarm is activated and the duration of the alarm after it is activated. There
are three alarm levels as described below:
— Alarm Level 0 (AL0) consists of activity with an error threshold below
the AL1 setting, which is deemed to be a satisfactory condition and
therefore no alarm will be activated.
— Alarm Level 1 (AL1) consists of activity with an error threshold above
the AL1 setting but below the AL2 setting that is deemed to be of minor
importance. 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 which is deemed to be of major importance. 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 Line-side E1 card will enter line-conditioning mode, and a
yellow alarm message will be sent to the CPE/LTU. Line processing will
send the Meridian 1 either all "on-hook" or all "off-hook" signals,
depending on the dip switch setting of the card. See Table 38, "Line-side
E1 card—E1 Switch 2 (S2) dip switch settings," on page 150.
