For powerful TCP/IP-based peripheral control and data communication,
these terminal servers are hard to beat.
OVERVIEW
Tired of 10-Mbps Ethernet terminal servers that still
“don’t do” TCP/IP and have no clue how to talk to your UNIX
computers?
Our Enhanced TCP/IP Terminal Servers are ready for your
network. They come in two 8- or 16-port varieties and one 2- or
4-port variety. The standalone 8- or 16-port version has regular
DB25 female RS-232 connectors (pinned as DTE). The rackmount
8- or 16-port version has RS-232 RJ-45 sockets. The standalone
2- or 4-port version has RS-232 RJ-45 sockets. (Both DB25 and
RJ-45 ports carry all signals necessary for full modem control;
you can use less expensive, more flexible twisted-pair cable with
the RJ-45 port.) You can set these ports for any standard data
format or flow-control option and for most standard async data
rates from 50 bps to 115.2 kbps.
You can attach a network cable to any one (but only one)
of the 8- or 16-port terminal server’s three Ethernet ports (AUI,
ThinNet, or 10BASE-T); it will autosense the connection and
establish its network presence immediately.
The terminal servers are compatible with every type of
UNIX we’ve tested them with, including Linux
®
, SCO
®
UNIX and
Gemini
®
, AIX
®
, Solaris
®
, HP-UX
®
, DG/UX
®
, BSD
®
, IRIX
®
, and Citrix
®
Winframe
®
. All models are also compatible with Windows
®
3.x,
95, 98, Windows NT
®
, and Windows 2000, though some
of their important features (such as TFTP and dial-out socket
connections) are not yet available under Windows.
Whatever you want to do with TCP/IP, the servers most
likely will handle the protocol. They operate with Telnet
™
and rlogin for session control; PPP, SLIP, and CSLIP for modem
and remote access support; lpd and rcp for printer support;
ARP and BOOTP for network-based setup; DNS for
internetworking support; and gateway tables for IP-routing
support, among others. The servers also fully support SNMP,
and they come with proprietary software that includes
utilities that extend modem and printer support, add “fixed
tty” support for terminals, and process proprietary SNMP
variables.
The servers have a pop-up menu system (with on-screen
help) that can appear in multiple terminals and in any of five
languages (English, French, Spanish, German, or Italian).
Security’s assured. The units support supervisor and port
passwords; port locking; authentication (including PAP); user
access profiles; logging for service, audit, and billing; and
modem auto-reset.
Two of the standalone (41872-R3, 41874-R3) and all four
of the rackmount terminal servers (40871-R3, 40871-DC-R3,
40870-R3, and 40870-DC-R3) are RoHS compliant.
