TELNET
Telnet provides remote log-on capability to a computer or server. The terminal to terminal connection with
Telnet is based on a TCP connection for traffic between user and server. Once login is established; the
controller will support this session until the “exit” command is received or the idle timeout limit is reached.
A command line interface is used to view and configure the controller’s features and thresholds. Backup,
restore, and upgrade procedures may also be performed.
SNMP
SNMP (simple network management protocol) is the most dominant network management standard. It
allows communication and control via open standards host systems for centralized management of multiple
plants. A number of vendors such as HP OpenView, IBM NetView, Lucent OneVision, and Sun Micro’s
NetManager have adopted the standard for telecommunication and computer equipment network
management. A standard MIB for the controller is available to be down loaded on the web at
. Up to four SNMP alarm trap destinations can be programmed using the Network
Settings link found in Settings Tab of the web pages. Alarms then can be assigned under Alarm Notification
also found in the Settings tab of the web pages. SNMP is more fully described in the Appendix.
SMTP
SMTP (simple mail transfer protocol) provides a basic electronic email facility. It provides a mechanism for
transferring messages among separate hosts and browser applications. The protocol is used in Gateway for
sending alarm messages and alerts through email.
FTP
FTP (file transfer protocol) is used to send files from one system to another under user commands. The
protocol is used with the controller for downloading files and upgrades through a TCP connection.
Application software, default configuration file, and web pages are uploaded to the controller using FTP.
TL1
TL1 is the transaction language command interface that allows direct communication with a central
monitoring system and is defined by Telcordia for various equipment. It allows communication and control
via open standards host systems for centralized management of multiple plants. The protocol is typically
used over a X.25 network for alarm reporting.
