Due to the nature of PPP, configuration options may not be agreed upon 
between two PPP peers.  This value is the number of configuration-naks 
that should occur before an option is configuration-rejected.  This allows 
a connection to succeed that might otherwise fail. The possible values are 
5 (def), 10, 15 and 20.

The dialing parameters for establishing this connection are defined under 
this menu.

This is the second number used for dialing a second B-channel when 
adding bandwidth.  If BACP/BAP is negotiated, this number is not nec-
essary.  If this number is not specified and BACP/BAP is not used, the 
Number 1

 number is re-dialed when adding bandwidth.

The call type can be configured in four different ways:

 

Speech directs the call control software to request a 
Mu-law encoded speech circuit as the bearer capabil-
ity for the outgoing calls.  The speech option is used 
with an ISDN line configured for voice service.  In 
some areas, voice service costs  less than data ser-
vices.  A speech call type does not always guarantee 
an end-to-end digital connection with some local  and 
long distance carriers.
