Installation and Operation Manual Chapter 1 Introduction
FCD-E1LC Ver. 1.0 Functional Description 1-17
• SNMP Management − The SNMP management capability enables fully
graphical, user-friendly management using the RADview network
management stations offered by RAD, as well as management by other
SNMP-based management systems.
• Telnet − Remote management is also possible using the Telnet
communication protocol, which uses TCP/IP communication, without the
SNMP service. Telnet support enables a remote IP host to control the
operation of FCD-E1LC using functions identical to those provided by a
supervision terminal.
The communication between the management system and FCD-E1LC can take
place out-of-band (by connecting to the serial management port) or inband
(through the main link). FCD-E1LC includes a proprietary IP router for
management traffic. This function enables FCD-E1LC to transfer management
traffic generated by, or addressed to, other FCD-E1LC units, and also inband
management traffic addressed to other RAD equipment that operates over E1
links, such as the Megaplex modular TDM E1/T1 multiplexers, DXC multiservice
access nodes, etc.
Dial-In and Dial-Out Capabilities
FCD-E1LC supports dial-in/dial-out operations, which can be used for remote
out-of-band configuration and monitoring (dial-in). For dial-out operation
FCD-E1LC activates the modem to automatically dial a pre-programmed number
whenever an alarm event occurs.
The remote out-of-band configuration, monitoring and sending callout alarm
messages can be done using the ASCII (terminal), PPP or SLIP protocols.
Alarms
FCD-E1LC stores alarms detected during its operation in a buffer that can hold up
to 100 alarms. During regular operation, an alarm indicator on the front panel is
used to notify the local operator that alarm conditions have been detected.
Separate indications are provided for major and minor alarms. The local operator
can then review the contents of the alarm buffer using the supervision terminal,
a Telnet host, or a management station.
The front-panel LED indicators display in real time the status of the main and
sublinks, and alert when test loops are present in the system. FCD-E1LC can also
automatically report alarms to a remote terminal using a dial-up modem. Alarms
causing dial-out activities are user-selectable.
The alarms stored in the FCD-E1LC alarm buffer can be transmitted automatically
through the serial management access port, for display on a supervision terminal;
when SNMP management is used, alarms are also sent to user-selected
management stations as traps.
The CONTROL DCE port can be configured to operate as a dial-out port, for
automatic reporting of alarms to remote locations. The port is intended for
connection to a Hayes™ or Hayes-compatible dial-up modem. You can program
the reporting method in accordance with the following options:
• Always send a report whenever a new alarm condition is detected.
