FCD-E1 Functional Description 1-19
In addition, FCD-E1 stores a set of factory-default parameters, which can be used
to start the configuration of a new FCD-E1 unit; the default parameters can also be
loaded in case the user’s database is corrupted.
FCD-E1 database management, as well as the other configuration, test, and
monitoring activities (equipment status reading, alarm status and history, activation
of test loops, reading of performance statistics, etc.) can be performed in three
ways:
• Supervision Terminal. A “dumb” ASCII terminal (or a PC running a terminal
emulation program), connected to the front-panel RS-232 serial ports of the
management subsystem installed in the FCD-E1, can be used as a supervision
terminal. The connection can be made either directly, or through modem or
low-speed data links. The FCD-E1 system supports both point-to-point and
multidrop connections.
The program stored in the FCD-E1 management subsystem controls the
supervision terminal.
• 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 generic SNMP-based
management systems.
• Telnet. Remote management is also possible using the Telnet communication
protocol, which enables management using IP communication in parallel with
the use of SNMP. Telnet support enables a remote IP host to control the
operation of the FCD-E1 system, using functions identical to those provided by
a supervision terminal.
When FCD-E1 includes the optional IP router, it is necessary to use a Telnet host
to configure the router parameters and supervise its operation (see Appendix F).
Serial Port Interface Characteristics
The serial ports of FCD-E1 units have standard RS-232 asynchronous interfaces.
CONTROL DCE Port
All the FCD-E1 versions have a front-panel RS-232 port designated CONTROL
DCE. This port enables direct connection to terminals, provided its interface is
configured as DCE (the selection is made by software commands). Since terminals
usually have DTE interfaces, the connection to the port is made by means of a
straight-through cable.
The CONTROL DCE port also supports the connection of a remote supervision
terminal through a modem link. For connection to a modem, you need a DCE/DTE
cross cable (also called null modem cable). Refer to Appendix A for cable wiring
information.
Two types of modems are supported:
• Dial-up Hayes compatible modems, e.g., the RAD miniature DLM/AT
modem.
• Multidrop modems, e.g., the RAD SRM-6 miniature multidrop modem.
For multidrop operation, each FCD-E1 system can be assigned a node address in
the range of 1 through 255. Assigning address 0 to a FCD-E1 system means that it
