TW-H6W1IR ISDN Remote Router
Configuration and Management
101
Before implementing MLPPP on the TW-H6W1IR, please ensure that
your ISP or the device to which you are connecting supports, and is
configured for MLPPP.
MLPPP can be implemented in two ways, dynamically through the use
of the Bandwidth on Demand (BOD), and statically. BOD causes the
second ISDN port to place a call and add bandwidth to the ISDN
connection when the
BOD High Threshold
is exceeded for the
Add
Bandwidth Delay
period. Bandwidth can also be subtracted when
ISDN throughput falls below the
BOD Low Threshold
and
Subtract
Bandwidth Delay
parameters. Thus, BOD economizes MLPPP by
maintaining only the bandwidth needed.
A static implementation of MLPPP is achieved when BOD is disabled
but the ISDN ports have Multi-Link enabled. In this case, when the
two ISDN ports have established a connection, the router will check to
see if they are connected to the same source and whether the source
supports MLPPP. If both conditions are met, the router will
automatically bundle the two links together as an MLPPP connection.
