Configuring the RSLS8 Value for ANSI Linksets

This procedure is used to configure the RSLS8 value for ANSI linksets feature using the chg-lsopts command with the lsn and rsls8 parameters.

The rsls8 parameter specifies how many bits of the SLS for messages on ANSI linksets are considered for bit rotation. The rsls8 parameter of the chg-lsopts command has two values.

yes - 8 bits of the SLS are considered for bit rotation.
no - 5 bits of the SLS are considered for bit rotation.

The lsn parameter specifies the name of the linkset that is being changed, specified in either Adding an SS7 Linkset or Changing an SS7 Linkset.

The rsls8 parameter can be specified only if the SLS Bit Rotation by Incoming Linkset feature is enabled. Perform Activating the SLS Bit Rotation by Incoming Linkset Feature to enable the SLS Bit Rotation by Incoming Linkset feature.

The value of the rsls8 parameter is shown in the RSLS8 column of the rtrv-ls output. The RSLS8 column is shown when the lsn parameter is specified with the rtrv-ls command, and is displayed only for ANSI linksets.

Refer to ITU SLS Enhancement for information on how the rsls8 parameter value is used with SLS bit rotation.

Display the RSLS8 value of the linkset that is being changed by entering the rtrv-ls with the name of the ANSI linkset that is being changed. For this example, enter this command
rtrv-ls:lsn=atmansi1

This is an example of the possible output.

If the RSLS8 column is not shown in the rtrv-ls output, the SLS Bit Rotation by Incoming Linkset feature is not enabled. Perform Activating the SLS Bit Rotation by Incoming Linkset Feature to enabled the SLS Bit Rotation by Incoming Linkset feature. After the SLS Bit Rotation by Incoming Linkset feature is enabled, the RSLS8 value for the linkset is set to no.

If you do not wish to change the RSLS8 value for the linkset, this procedure does not need to be performed.

If you wish to change the RSLS8 value, continue the procedure with 2.
Change the rsls8 parameter value using the chg-lsopts command.
If the current RSLS8 value is no, for this example, enter this command

chg-lsopts:lsn=atmansi1:rsls8=yes

If the current RSLS8 value is yes, for this example, enter this command

chg-lsopts:lsn=atmansi1:rsls8=no

When this command has successfully completed, this message should appear.

```

Verify the changes by entering the rtrv-ls command with the name of the linkset that was specified in 3.

rtrv-ls:lsn=atmansi1

This is an example of the possible output.

Back up the new changes using the chg-db:action=backup:dest=fixed command.

These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

BACKUP (FIXED) : MASP A - Backup starts on active MASP.
BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
