Specifies the transmission group (TG) number that represents the connection between this node and the destination APPN node.
By specifying a tg_number, you indicate a preferred TG that might be used depending on how the partner nodes negotiate the number.
Coding TGN=ANY, or not coding TGN, allows the transmission group number to be negotiated.
Coding TGN=0 means that the PU does not support parallel TGs. For connections to LEN nodes, or to any node that does not support parallel TGs, TGN=0 is always assumed.
For APPN-capable nodes, the CPNAME and NETID operands are required with the TGN operand. Note that you can specify the CPNAME operand without the TGN operand and the transmission group number will be negotiated. However, if a value for TGN is specified, then a value for CPNAME and NETID must also be specified.
