BACP: This selects BACP dynamic bandwidth allocation.
Note that the Maximum Channels on the Bandwidth tab (see page 49) must be
set to 2 or more if this option is selected.
Compression Mode: The Compression mode can be either disabled or
chosen as one of two proprietary methods, either StacLZS (STAC Mode 3
compression) or Microsoft MPPC compression.
Callback Mode: The Callback mode can be either disabled or selected from the
following:
LCP (Link Control Protocol) - after authentication the incoming call is dropped
and an outgoing call to the number configured in the Service will be made to
re-establish the link.
Callback CP (Microsoft's Callback Control Protocol) - after acceptance from
both ends the incoming call is dropped and an outgoing call to the number
configured in the Service will be made to re-establish the link.
Extended CBCP (Extended Callback Control Protocol) - similar to Callback
CP however the Microsoft application at the remote end will prompt for a
telephone number. An outgoing call will then be made to that number to re-
establish the link (the line access prefix digit must be added).
Access Mode: Select the type most suited to the service. The options are
described in the table below.
