Concurrent Conversations

To conduct concurrent conversations between any two programs, the use of parallel sessions must be supported between them. The number of concurrent conversations that can be established between programs is dependent upon the number of parallel sessions available.

Note: Applications running under a PU Type 2.0 node, such as PC-based applications, must always play the role of Secondary LU and are restricted to a single LU6.2 conversation at any given time. Use of Node Type 2.1 and independent LUs allows such devices to play the role of a Primary LU (BIND sender) and also allows a parallel session capability.
