Description
Alternative Call Routing for Network Bandwidth Management (NBWM) is
available for CS 1000 Release 4.5 and CS 1000 Release 5.0 .
Alternative Call Routing for Network Bandwidth Management (NBWM)
allows a station-to-station call (that is, a call that does not use a trunk)
between a branch office and main office to overflow to traditional routes.
Overflow can occur if there is insufficient interzone bandwidth available
to carry the call or if the Quality of Service (QoS) has degraded to
unacceptable levels. The feature also applies to station-to-station calls
from one branch office to another branch office, provided both stations are
registered to the same main office.
Figure 65 "Example of Alternative Call Routing for NBWM in operation"
(page 160)
shows a diagram of a typical network where Alternative Call
Routing for NBWM can be used. It illustrates the sequence of events that
are explained in the information following the diagram.
