A CIT is recommended for installation, maintenance and administrative activities.
A personal computer (PC) is required for software download and to run the
CPro-2000 software. The DDM-2000 OC-3 Multiplexer CIT port (mounted on the
user panel) is a standard EIA-232-D (supersedes RS-232C specification)
interface configured as DCE for direct connection to a CIT. The CIT port will
support rates of 300, 1200, 2400, 4800, 9600, and 19,200 baud and should be
compatible with most
ANSI
3.64 ASCII terminals; however, it is optimized for
standard screens with display areas of 24 lines by 72 (or more) columns. A pager
function is included in the DDM-2000 OC-3 Multiplexer to accommodate screen
lengths from 3 lines to 150 lines.
Those CITs compatible with DDM-1000 (see 363-206-100 for a list of DDM-1000
compatible terminals) should be directly compatible with the DDM-2000 OC-3
Multiplexer, although some may not be as convenient to use with the DDM-2000
OC-3 Multiplexer.
If the multishelf bus cables (ED-8C724-20, G354 or G356) are connected
between shelves in a bay, a CIT may then be connected to the user panel CIT port
on any shelf and may address any other shelf in that bay (as well as the remote
terminal shelves associated with that shelf in the bay). Any terminal compatible
with the
ANSI
3.64 standard should be compatible with the DDM-2000 OC-3
Multiplexer.
Personal Computer (PC) Specifications for Software
Download
1 0
The PC used for software download should have:
■
A minimum of 640K of random access memory (RAM)
■
MS-DOS
*
version 2.0 or newer
■
Hard disk
■
At least one floppy disk drive of 360K or larger capacity. Although the disk
drive may accommodate either floppy or hard disk, a hard disk is preferred
for its better performance. The disk requirement is met with most portable
MS-DOS
PCs with a single 3.5-inch disk. An
MS-DOS
PC with a hard disk
and either a 3.5-inch 1.44M floppy disk may also be used.
■
Windows NT* available to work with the OC-3 releases 7.2 and earlier and
13.0 and later and OC-12 releases 7.0 and later.
