Defines the 3-digit or 4-digit hexadecimal device number of the channel attachment for the communication controller in which the NCP runs.
If you omit CUADDR and the VTAM® operator wants to activate the communication controller over a channel, the operator should provide an address in the U operand when issuing the VTAM VARY ACT command.
If no channel device address or link station contact points are coded (with the CUADDR and RNAME operands of the PCCU definition statement) and none are provided on the VARY ACT command, a link station adjacent to the communication controller must already be active and defined to the host before the operator can activate the controller.
Note: If you plan to define the channel to the NCP in a
channel-attachment major node, this operand is replaced by the ADDRESS
operand on the LINE definition statement for the channel-attachment
major node. See ADDRESS for a description
of the ADDRESS operand in a channel-attachment major node.
