OUTING
The PPP channel_expansion and PPP channel_decrement parameters are
associated with MLPPP operation. When the utilization of the link reaches
these values, either more links are made available (channel expansion) or
links are removed (channel decrement).
When MLPPP brings up additional links, the RAS 1500 uses the same
number it brought up for the first link. Therefore, the destination to
which the MLPPP connection is to be established should have its phone
lines in a hunt group.
Example:
set network user main_office ppp
compression_algorithm stac
max_channels 2
channel_expansion 60
channel_decrement 20
2 Configure optional PPP parameters.
set network user <username> ppp
expansion_algorithm <linear or constant>
min_size_compression <0-2047 bytes>
reset_mode_compression <when to reset>
receive_acc_map <accm>
transmit_acc_map <accm>
Example:
set network user main_office ppp
min_size_compression 256
reset_mode_compression auto
receive_acc_map 00000000
transmit_acc_map 00000000
Step Six: Configure
Phone Numbers
Use the following command to configure primary and alternate phone
numbers:
set user <username>
phone_number <number 1>
alternate_phone_number <number 2>
The RAS 1500 attempts to dial the phone number when a connection is
required. If the RAS1500 is unable to establish a link on this number, it
attempts to dial the alternate phone number.
