Use the LINK statement to define the NPSI MCH LU names. One SNA control session is established for each MCH LU defined by a LINK statement.
Syntax
>>-LINK--mchlu_name--+-DDN-----------+--------------------------> '-dnic dte_addr-' >--window_size--packet_size--logical_channels------------------><
Parameters
- mchlu_name
- The name of the physical circuit logical unit (NPSI MCH LU).
- DDN
- Use DDN for the Defense Data Network.
- dnic
- The X.121 Data Network Identifier Code (DNIC) for the public data network. The dnic parameter can be coded as PRIVATE or PRIV to denote a private X.25 network.
- dte_addr
- The X.25 DTE address for the link. The address must be from 1 - 15 decimal digits. This parameter is not coded for DDN links. Specify dte_addr as NONE to omit the calling address from the call request packet.
- window_size
- The window size to negotiate on switched virtual circuits, in the range of 1 - 7 for a modulo-8 network, or 1 - 127 for a modulo-128 network.
- packet_size
- Choose one of the following X.25 packet sizes as the default: 32, 64, 128, 256, 512, 1 024, 2 048, or 4 096 bytes.
- logical_channels
- The number of logical channels (switched virtual circuits) subscribed, in the range of 1 - 1 023.
Examples
In the following example, AU20 is the name of a non-DDN network, and AU16 is the name of a DDN network.
