GPRS port Telnet mode:
On models
fi
tted with GPRS, this parameter is used to select the Telnet mode when a remote entity is
connected to the GPRS port via TCP/IP. The three available options are the same as those for
ASY
<port> Telnet mode
described above.
PSTN port Telnet mode:
On models
fi
tted with an analog modem, this parameter is used to select the Telnet mode when a
remote entity is connected to the PSTN port via TCP/IP. The three available options are the same as
those for
ASY <port> Telnet mode
described above.
Allow anonymous FTP login:
This parameter is used to allow or disallow anonymous FTP logins to the unit. Default is “Off”
(disallow anonymous logins).
TCP socket inactivity timer (s):
This speci
fi
es the maximum period of inactivity (in seconds) that may occur before an open TCP/
IP socket is closed. The default value is 300 seconds (5 minutes) and should not normally require
altering.
TCP socket keep-alive (s):
This speci
fi
es the amount of time (in seconds) between sending “keep-alive” messages over open
TCP connections. The purpose of these messages is to prevent a connection from closing even when
no data is being transmitted or received. The default value of this parameter is zero, which disables
keep-alive messages.
TCP socket connect timeout (s):
This parameter is used to specify the amount of time after which a TCP socket may remain idle before
being closed. If the value is set to 0 the socket may remain open inde
fi
nitely.
SNMP enterprise number:
This parameter speci
fi
es the value of the Object Identi
fi
er component following “enterprises” to be
used by SNMP managers when accessing the MIB on the unit. Object Identi
fi
ers of objects in the
unit’s SNMP MIB have the pre
fi
x “{ enterprises n ir2140 }” where “n” is the SNMP enterprise number.
SNMP enterprise name:
This speci
fi
es the name corresponding to the SNMP enterprise number above.
SNMP community string:
This speci
fi
es the required SNMP Community String to be used by SNMP managers in order to
access the unit’s MIB.
SNMP trap destination address:
This is the IP address (or host name) of the destination for SNMP trap messages.
GP sockets use IP from interface:
This parameter allows general-purpose TCP sockets to use a source IP address other than that of
the interface on which the socket connection is created. The unit creates general-purpose sockets
automatically when your application requires them, e.g. when TPAD calls are made over IP or XOT.
Normally, the source address used by the socket will be that of the outgoing interface (usually PPP).
However, for some applications such as when setting up a VPN, it may be necessary to specify that
the socket use a different source address such as that of the local Ethernet port. This parameter is
used to specify from which interface the source address should be derived and may be set to “None”
(default), “ETH” or “PPP”.
Note:
Even when this parameter is not set to “None”, normally the IP address from the interface on which
the socket is created will be used. The source address speci
fi
ed in this parameter will only be used if
it will cause the traf
fi
c to match an Eroute and therefore be sent over IPSec or GRE.
