3-4 Configuration and Management Alternatives FCD-E1LC Ver. 1.0 
Typically, the Telnet host is a PC or a UNIX station with the appropriate suite 
of TCP/IP protocols. The host can be directly connected to the managed 
FCD-E1LC unit. However, the host may also be located at a remote site, the 
only requirement being that IP communication be established between that 
site and the managed FCD-E1LC unit (either out-of-band through a separate 
network, using the SLIP or PPP protocol, or inband through the main and/or 
sublink). 
•  Configure the FCD-E1LC unit by means of SNMP-based network management 
stations. 
Routine Management 
During regular operation, the FCD-E1LC unit can be managed using any of the 
options listed above for system configuration. 
Supervisory Terminal Characteristics 
Any standard ASCII terminal (“dumb” terminal or personal computer emulating an 
ASCII terminal) equipped with a V.24/RS-232 communication interface can be 
used to control FCD-E1LC operation. 
Control Port Interface Characteristics 
FCD-E1LC has a V.24/RS-232 asynchronous DCE port, designated CONTROL DCE 
and terminated in a 9-pin D-type female connector. The control port continuously 
monitors the incoming data stream and will immediately respond to any input 
string received through this port. Moreover, when the FCD-E1LC control port is 
configured to support the SLIP or PPP protocol, messages in each of the 
supported protocols are automatically identified and processed. 
The supervisory terminal can be connected to the FCD-E1LC control port either 
directly, or through a modem or any other type of full-duplex data link: 
•  For direct connection to the control port, use a straight-through cable. 
•  For connection to the control port through a modem or data link, use a 
cross-cable (also called null modem cable). 
FCD-E1LC can communicate with the supervision terminal or modem at rates of 
1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bps. The word 
format consists of one start bit, 8 data bits, and one or two stop bits. Parity can 
be odd, even or disabled. 
Always make sure the communication interfaces of the terminal/modem and the 
FCD-E1LC are configured for operation with the same parameters. 
Modems 
The CONTROL DCE port also supports the connection of a remote supervision 
terminal through a modem or low-speed data link: in this case, configure the 
control port interface as DTE and use a cross-cable (also called null modem cable) 
to connect to the CONTROL DCE port.
