8. TERMINAL MANAGEMENT
8.01
The terminal management function at the
remote terminal enables a technician to monitor
the entire PG-Flex system through an ASCII terminal (or
equivalent) connected to the maintenance port. The pin-
outs for the standard RS-232 (DB-9) maintenance port
connector are shown in Figure 4. With the management
function, the technician can view status, configuration,
performance, and inventory information.
8.02
Craft Maintenance Port. The craft maintenance
port to which the management terminal
connects is available at both the CO Line Unit and all RT
Line Units. The craft port is set up as DCE with 8 data
bits, 1 stop bit, and no parity. Striking the SPACE bar
rapidly several times invokes the autobaud feature,
which covers a 1,200 to 9,600 bps range.
8.03
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
•
Status. By selecting the Status option (A)
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:

ALRM: The channel is in alarm.
– Display HDSL Status to show the status

NONE: The segment is not equipped.
– Display Performance History to show
the 24-hour performance history or the
