FRAS BNN Connections
To complete the FRAS BNN connection, proceed as follows:
1.
2.
addport <port_num> <line_num> <line_speed> <begin_slot> <port_type> <port_role> <encoding>
<interface>
<port_num>
<line_num>
<line_speed>
<begin_slot>
<port_type>
<port_role>
<encoding>
<interface>
3.
Release 5.0, Part Number 78-6430-03 Rev. D0, November 2003
Enter the addln command to specify the physical port number (from 1 to 8) that is to be used for
the FRAS BNN connection.
Enter the addport command to specify a port number for the connection and to specify its
parameters. Specify the port speed, the slot number, the encoding to be used, and the type of DS0
interface. The port type field is used to specify the connection as a FRAS BNN connection. The
role (primary, secondary, and so forth) of the FRASM port to be used in the link protocol must be
specified.
port number in the range 1–192
value ranging from 1–8
1 for 2.4K, 2 for 4.8K, 3 for 9.6K, 4 for 56K, 5 for 64K
time slot number in the T1 frame
1, 2, or 3: 1 = STUN, 2 = FRAS, 3 = BSTUN
1, 2, 3, or 4: 1 = Primary, 2 = Secondary, 3 = Negotiable,
4 = XIDPrimPoll
1 or 2: 1 = NRZ, 2 = NRZI
1 or 2: 1 = DS0, 2 = DS0A
Once the line and port have been specified, use the add link station command (addls) to specify the
FRASM port link station address and xid (exchange ID). A link consists of two link stations and
the connecting transmission medium. In order to start an SNA session, a link between the two nodes
needs to be established. In an FRAS BNN connection the SNA part of the connection is terminated
at the FRASM; a session requires that the FRAS BNN port act as a link station. The link station
name and the xid are used during the process of establishing a link.
