{
{      This subcommand provides the operator with the capability of changing
{ the state of an LCN trunk, with respect to specified NADS defined in the
{ currently active RHFAM configuration, to ON or OFF. OFF states are not
{ preserved when the RHFAM system task is de-activated. Setting a trunk
{ connection for a NAD to OFF will prevent the use of that trunk connection
{ on subsequent connect requests made from the local host. Any currently
{ active connection using the trunk connection will not be affected.
{
{      The caller must have NETWORK_OPERATION capability specified in the
{ validation file, or be the system job in order to use this command.
