Security The terminal server, as a front end, provides
secured access to host devices. , All users
connecting to the terminal server through the
network, modem, or the AUX Port need to
authenticate before being passed through to
a host device or permitted to administer the
terminal server. The terminal server also
provides a logical switching function that
allows an authorized user to connect to any
host device listed in the user’s profile.
Site Connectivity The terminal server acts as a central point for
connection to all hosts and other serial
devices at a site. It enables connections
through a local terminal, dial-up modem, and
Ethernet. A dial-up modem also provides a
PPP connection, allowing remote access to
networked devices.
Alarm Processing When attached to a maintenance port, the
terminal server can process alarm messages
and other ASCII based data streams. Alarm
messages can be delivered via a modem or
network connection. Using either PPP or
network connectivity, the terminal server can
deliver SNMP traps to network managers.
The terminal server can convert ASCII-based
alarms received on its host ports to standard
SNMP traps. Acting as a SNMP trap proxy
agent, the terminal server allows legacy
equipment to be managed and provides
alarm-reporting functions.
Data Buffering The terminal server can buffer all data
transmitted to a host port by the attached
