Set Date
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 sets 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 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 the AL2 setting that is deemed to be of
minor importance. In this situation, the external alarm hardware is
activated by closing the normally open contact, the RED ALARM LED
on the faceplate lights, and an alarm message is 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 following happens:
— the external alarm hardware is activated by closing the normally
open contact
— the RED ALARM LED on the faceplate lights
— an alarm message is created in the alarm log and the MMI terminal
— the LEI card enters line-conditioning mode
— a yellow alarm message is sent to the CPE/LTU
Line processing sends the CS 1000E, CS 1000M, and Meridian 1either all
"on-hook" or all "off-hook" signals, depending on the dip switch setting of
the card. See
Table 104 "LEI card - E1 Switch 2 (S2) dip switch settings"
(page 271) .
When the Set Alarm command is selected, the prompt appears for
setting the threshold level and duration for alarm levels 1 and 2.
The E1 link processes at a rate of approximately 2.0 mb/s. The threshold
value indicates the ratio of the total number of bits that must be detected
as being in error per second before the LEI activates an alarm. It can
be set between 3 and 9 and can be different for each alarm level.
Any other value entered causes the MMI to display a
