Specifies the three- or four-digit device number of the channel-to-channel adapter (CTCA) or the channel-attached NCP. If you do not code this operand, the VTAM® operator must supply the device number by specifying the U operand of the VARY ACT command. See z/OS Communications Server: SNA Operation for details on using the U operand.
Note: For a channel-attached NCP, this channel-link definition might conflict with a
channel-link name automatically defined by VTAM if you attempt to have this channel definition
and an automatically defined channel link for the same device number
active at the same time. (A channel link is defined automatically
if an NCP is activated and a CUADDR value is included on its PCCU
definition statement, or if the operator issues a VARY ACT command
with U=device number.) The second activation
(either this definition or the automatic definition) will fail. For
more information on channel-attached NCPs, see the z/OS Communications Server: SNA Network Implementation
Guide.
