Multiple PPP Instances
It is also possible to configure multiple instances of a particular entity to answer. For example,
PPP instance, 0, 1 and 4 could be configured to answer. In this case, provided none of the PPP
instances are busy, the PPP instance with the highest number will answer first. MSNs can also be
used to ensure that a chosen PPP instance answers the call.
The multiple protocol entity answering instance rules are as follow:
Adapt
The lowest free Adapt instance with auto-answering enabled will answer first.
PPP
The lowest free PPP instance with answering on will answer first.
LAPB
The lowest free LAPB instance with answering on will answer first.
