The following parameters are those that you are most likely to need to customise PPP for your
application. More advanced settings are covered in the next section.
Using the Web Page(s)
Name:
This parameter allows you to enter a name for this PP instance, to make it easier to identify it.
IP analysis:
This parameter is used to include or exclude IP data from this PPP instance from the analyser trace
and is equivalent to checking or un-checking the equivalent
IP sources
checkbox on the
Confi gure
>
Analyser
page.

Answering:
If this parameter is set to “On”, the unit will answer incoming calls on the relevant PPP channel. To
prevent the unit from answering incoming calls on this PPP channel set the option to “Off”. If PPP
Answering is set to “Calling”, the unit requires the remote peer authenticate itself, but only if the
remote peer has dialled in.
Calling number:
This parameter is used to restrict the range of numbers from which PPP will answer incoming calls,
i.e. PPP will only answer a call if the trailing digits of the calling number match what is speci
fi
ed by
this parameter. For example, if Calling Number was set to 3, incoming calls from 1234563 would be
answered but calls from1234567 would not.
MSN:
If
Answering
is “Off” this parameter is not used. This parameter provides the
fi
lter for the ISDN
Multiple Subscriber Numbering facility. It is blank by
default but when set to an appropriate value with
Answering
set to “On” it will cause the unit to
answer incoming calls to only telephone numbers where the trailing digits match the value selected.
For example, setting MSN to 123 will prevent the unit from answering any calls to numbers that do not
end in 123.
Sub-address:
If
Answering
is “Off” this parameter is not used. This parameter provides the
fi
lter for
the ISDN sub-address facility. It is blank by default but when
set to an appropriate value with PPP Answering On it will cause the unit to answer incoming calls
only to ISDN numbers where the trailing digits match the Sub-address value. For example, setting the
Sub-address parameter to 123 will prevent the unit from answering any calls to numbers that do not
end in 123.
CLI:
Calling Line Identi
fi
cation. The unit will only answer calls from numbers whose trailing digits match
what is entered in this
fi
eld. The line the unit is connected to must have CLI enabled by the telecoms
provider, and the calling number cannot be withheld.
