Menus and Displays. Figure 5 shows the menu
structure of the terminal management system.

Table 4 defines the terms appearing on the Status
displays. Following are brief descriptions of each menu
and display screen:

• 

Log On Screen. The Line Unit displays this
screen when it detects the user's input from
the maintenance port while in an idle state.
Password input is echoed with "*" characters.
If the technician does not enter the correct
password after 5 tries, the Line Unit locks out
the log on procedure for 10 minutes.

• 

Main Menu. After receiving a correct
password, the terminal displays the Main
Menu from which the technician can choose
any of the following options:

– Status

– Setup

– Inventory

•

from the Main Menu, the technician can:

– Display System Status to show the

equipment installed in the system and the
current status (in alarm or not) of the
equipment. An "*" next to the unit name
indicates that the unit is currently in the
alarm state.

– Display Channel Status to show the

current status of all channels in the
system. Each channel has one of the
following status conditions:

IDLE: The channel is not off-hook or
ringing.

RING: The channel is ringing.

OH: The channel is off-hook.

ALRM: The channel is in alarm.

– Display HDSL Status to show the status

of all the HDSL segments and request the

user to select the segment of the HDSL to
be displayed. Each HDSL segment has
one of the following status conditions:

ACTIVE: The segment is functioning
normally.

ALARM: The segment is in alarm.

NONE: The segment is not equipped.

– Display Performance History to show the

24-hour performance history or the 7-day
performance history of the HDSL segment
