3-10 Local Configuration Setup Procedure FCD-E1
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 the
SNMP Management appendix), the connection of a Telnet host to one FCD-E1 unit
may provide management access to many interconnected FCD-E1 units. This
connection can also provide management access to other types of equipment that
support this type of management (for example RAD’s MEGAPLEX and MAXcess
multiplexers, DXC multiservice access nodes, FCD-E1 and FCD-T1 fractional E1,
respectively T1, integrating multiplexers, etc.).
Connection to Serial Ports (Out-of-Band Communication)
Telnet hosts can connect to a serial FCD-E1 port: either to the CONTROL DCE
port or to the CONTROL DTE port, available on all FCD-E1 units.
• The connection to the CONTROL DCE port is made as explained in the
Connecting Supervision Terminals on page 3-8. Both direct connection, and
connection through a modem link, are possible. The use of multidrop
configurations is not recommended.
When connecting to the CONTROL DCE port, make sure to disable the
AUTOBAUD function, otherwise communication using the SLIP protocol is not
possible.
• The connection to the CONTROL DTE port is made as explained above in the
Connecting Alarm Monitoring Terminals on page 3-9.
To enable using the appropriate protocol (SLIP or PPP) at the CONTROL port,
make sure to configure the CONTROL port interface as DCE (this is performed
by internal switches).
Connecting 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).
3.5 Local Configuration Setup Procedure
Before starting any configuration action:
• Review relevant configuration parameters listed in Appendix D.
• Review a list of the required parameters from your network subscription data
and/or from your system administrator.
• Make sure that all the user-initiated loopbacks are disconnected. To
disconnect the loopbacks, select OFF in the TEST OPTION field (refer to
Chapter 5).
