4.3 OPERATIONAL CONFIGURATION
There is an implicit one-to-one mapping of SAM504 boards/ports (as the node views them) to the
UMI’s virtual ports (“vports”), as shown in the following table. These associations are built into the
UMI module software, and will need to be kept in mind for proper coordination of node and
module administration procedures for operational configuration.

It’s important to note that although a single UMI supports call setup in both directions
simultaneously, each grouping of virtual ports must be configured for one direction only; i.e., there
are no two-way virtual ports. In addition, virtual ports intended to be used for synchronous and
asynchronous call connections must reside in different groups, since their protocol encapsulation
is different.
The following subsections describe how the node and UMI are jointly configured to enable calls to
be set up in each direction.
4.3.1 BNS-to-IP Calling
UMI virtual ports designated as originating, as part of module-based administration, are for the
BNS-to-IP calling direction . From the node administration perspective, the corresponding SAM
ports are set up as host service-type ports, since they receive calls from the BNS network.
Predefined destination (PDD) information, in the form of a destination IP address and TCP port
number, may be optionally set up on the UMI for each virtual port.
For UMI virtual ports configured as originating, operation from the perspective of a user calling
from somewhere in the BNS network is determined by whether or not a PDD has been specified
for the virtual port chosen to originate the call. An originating-type virtual port which has a PDD
associated with it will have that connection automatically established at the time a BNS
connection is made to the UMI. If no PDD has been specified, the calling user is greeted with a
UMI Destination> prompt each time the virtual port receives a BNS connection. The user would
then enter the destination IP address plus TCP port number desired. If no TCP port number is
