FRASM Connections
3. 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 STUN connection. The role
(primary, secondary, and so forth) of the FRASM port to be used in the link protocol must be
specified.
addport <port_num> <line_num> <line_speed> <begin_slot> <port_type> <port_role> <encoding>
<interface>
4. Enter the add STUN port command (addstunport) to establish a group number for the connection.
addstunport<port_num><group_num>
5. Once the group, line, and port have been specified, enter the add link station command (addls) to
specify the FRASM port link station address and xid. 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. Since in a STUN connection the SNA can be 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.
addls <port_num><lsaddress><xid>
<port_num> port number in the range 1–192
<line_num> value ranging from 1–8
<line_speed> 1 for 2.4K, 2 for 4.8K, 3 for 9.6K, 4 for 56K, 5 for 64K
<begin_slot> beginning timeslot number in the T1 frame
<port_type> 1, 2, or 3: 1 = STUN, 2 = FRAS, 3 = BSTUN
<port_role> 1, 2, 3, or 4: 1 = Primary, 2 = Secondary,
<encoding> 1 or 2: 1 = NRZ, 2 = NRZI
<interface> 1 or 2: 1 = DS0, 2 = DS0A
<port_num> port number in the range 1–192
<group num> group number to which the connection is to be assigned
<port_num> Port number in the range 1–192.
<lsaddress> LS address in the range 0x01–0xFF. If virtual multidrop and FF ACK Mode
is set, the address FF can be configured as a link station.
<xid> 4-byte Hex number that is to be exchanged for this station in the range
0000–FFFFFFFF.
