4-2 T ERMINAL O PERATION
Modem
Compatibility
The 2000 CSU Terminal Interface supports use of an AT command-set-compatible
modem on either or both of the NMS IN/OUT and SUPV serial ports. The modem
should be optioned to ignore DTR, enable auto answer, inhibit command echo, and
return verbose result codes.
Calling the 2000 CSU and sending the break command before receiving the connect
message, hangs up the modem.
Screen
Components
Terminal interface screens have several components common to all screens and are
discussed individually in the following paragraphs. These common screen elements
are shown on the Password Screen (Figure 4-1).
Device Type and Revision
The device type (2000 CSU) and the revision control numbers are shown in the
upper left corner. The first number is the hardware revision and the second number
is the software revision. Information is displayed for the near-end unit (connected
directly to the terminal) on the top line, and for the far-end unit (connected to the
network T1 interface) on the second line. Refer to this information when
contacting the factory with inquiries.
The far-end information is available only for TxPORT products that support a
proprietary message set. If the far-end does not support these messages but does
support standard 54016 protocol, the far-end information is displayed as
GENERIC 54016 FAR END. If the far end does not respond to either proprietary
or 54016 messages, then NO FAR END RESPONSE is displayed. If the far end
echoes the FDL messages transmitted by the near-end unit, then FAR END LINE
LOOP is displayed.
Date/Time
The top right corner of the terminal screen displays the current date and time. The
setting of these functions is described in Set Time on page 4-20.
Unit Address
Below the unit header (2000 CSU), the current unit address is displayed along with
any information entered in the Element ID field of the Utilities screen.
