TG_NUMBER

Required? No
Keyword Type Unsigned number
Default 0
Range 0–20
Multiples Allowed? No, only one for each LINK_STATION keyword
   TG_NUMBER = (
      @TYPE = UNSIGNEDNUMBERKEYWORD
      @RANGE = 0,20
      @DEFAULT = 0
    )

The TG_NUMBER parameter specifies a preassigned TG number. This field is only relevant if the link is to an adjacent APPN® node and is otherwise ignored.

This parameter is optional. The default is 0.

Note:
  1. If ADJACENT_NODE_TYPE is specified as SUBAREA_LEN, TG_NUMBER is ignored and assumed to be specified as 1.
  2. For links to adjacent APPN® nodes, TG_NUMBER must be set in the range 1–20. This number is used to represent the link when the link is activated. Communications Server does not accept any other number from the adjacent node during activation of this link.
  3. To avoid link-activation failure because of a mismatch of preassigned TG numbers, the same TG number must be defined by the adjacent node on the adjacent link station (if using preassigned TG numbers).
  4. If a preassigned TG number is specified, the FQ_ADJACENT_CP_NAME must also be defined (and can not be set to all zeros) and the ADJACENT_NODE_TYPE must be specified as NETWORK_NODE or END_NODE.
  5. If zero is entered, the TG number is not preassigned and is negotiated when the link is activated.
