Specifies whether the switched subarea connection made using this PATH definition statement should be a short-hold mode connection.

SHM is mutually exclusive with the LINENM operand. It is valid only for connections established through X.25 NCP Packet Switching Interface (NPSI).
SHM=NO
Specifies that short-hold mode is not to be used.
SHM=YES
Specifies that short-hold mode is to be used, and the value specified by the SHMTIM operand should be used as the short-hold mode timer.

When SHM=YES, the DIALNO and GRPNM operands are required. The GRPNM operand is used to specify which group is appropriate for this PATH definition statement.
