Telnet (IP) Host Characteristics
Typically, the Telnet host is a PC with the appropriate suite of TCP/IP protocols, or
a UNIX station.
The Telnet host can be directly connected to the managed FCD-E1LC unit, or be
located at any site from which IP communication can be established to the
managed FCD-E1LC.
Connection of Telnet Hosts
Telnet enables communication with multiple FCD-E1LC units, using either inband
or out-of-band communication.
• For communicating out-of-band using the SLIP or PPP protocol, the Telnet
host can be connected (or be able to communicate) to the control port of the
FCD-E1LC unit.
• For inband communication, the user can enable the transfer of management
traffic through the main and/or sublinks.
The Telnet protocol operates over IP. Since the IP traffic is automatically routed
to the desired unit through the internal IP routers of chained equipment (see
background information in
Appendix B and Appendix C), a Telnet host capable of
communicating with one FCD-E1LC unit may provide management access to
several interconnected FCD-E1LC units, as well as to many other types of
equipment that support this type of management (this includes many RAD
network products, for example, Megaplex-2100, DXC multiservice access nodes,
multiplexers, etc.).
Connections for SNMP Management
The SNMP protocol also operates over IP, therefore all the requirements
described above for Telnet management also apply to the connection of SNMP
network management stations.
Multidrop configurations must not be used with SNMP, because multidrop
operation requires that all the units strictly observe the rules of polled
communication. This is not true for SNMP agents, because they can initiate
transmissions on their own (whenever they have a trap to transmit).
3.4 Turning Off the Unit
³ To turn the FCD-E1LC off:
Disconnect the power from the FCD-E1LC.
