Terminal Interface A-1 PRISM 4151
A. Terminal Interface
This chapter describes the screens structure and menu con-
trols for the TxPORT PRISM 4151 terminal interface. The
interface is a firmware application program embedded
inside the unit.
It requires an ANSI compatible VT100 terminal (ASCII), or
a computer running an ANSI terminal emulation program.
The terminal interface uses ASCII BREAK and ESCAPE
functions, which are implemented differently with the vari-
ous terminal emulation programs.
Screen Components
Terminal interface screens have several components com-
mon to all screens (Figure A-4).
Device Type and Revision: The device type (such as
PRISM 4151) 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. Far end information is displayed only when activated,
otherwise, No Remote Access is displayed. Refer to this
information when contacting the factory with inquiries.
Date/Time: The top right corner of the terminal screen dis-
plays the current date and time. The setting of these functions
is described in the section entitled Utilities on page 3-10.
Element ID: Below the header (PRISM 4151), the Element
ID is displayed. Refer to the section entitled Management
Ports on page 3-8 for information on the Element ID.
Menu Title: The menu title (third line, center) denotes the
general classification of functions currently accessible by
the user (such as MAIN or PERFORMANCE).
Messages: Diagnostic messages may be displayed at the
bottom of the screen.
Cursor Controls
The terminal interface utilizes a highlighted cursor to make
selections from menus and select fields within screens to be
operated on. The cursor is moved in different ways, depend-
ing on the terminal emulation program used. Most programs
allow use of the <tab> and <shift-tab> keys. Others allow
use of the arrow keys. Once a field is highlighted, it is
manipulated as described in Section .
For keyboards which do not have these standard keys or
have only some of them, an alternate set of cursor control
commands is provided. Each command is performed by
pressing a letter key while holding down the <Ctrl> key.
