ACO Pushbutton
This pushbutton functions as an LED test by
turning on all LEDs when pressed and held for
at least 1 second. When the pushbutton is
released, LEDs resume their normal status
indications. The LEDs remain active for 2
minutes, at which time the channel unit LEDs
turn off to conserve power at the remote
terminal.

RS-232
DB-9F Connector
This connector is used by technicians to
configure the PG-Flex. This is a DCE interface
and requires DTE active from the terminal to
prevent automatic log off.
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.
Figure 4. FRL-772 DB-9 Pin Outs. A standard RS-232
(DB-9) connector on the front panel provides access to
the menu interface feature via an ASCII terminal.
