| Client 
				 | 
 
				A machine, running a COBOL system, where you install communications client software. This machine accesses a host CICS environment via a local server. 
				 | 
 
			 
 
			  
				| Data Link Control (DLC) link 
				 | 
 
				The interface to the network. The attributes of a link can be divided into two parts: 
				   
					 - Characteristics of the port (logical and physical) 
					 
 
 
					 - Control characteristics of the link 
					 
 
 
				   
 
				 | 
 
			 
 
			  
				| Control Point (CP, CP Name) 
				 | 
 
				Identifies the local node manager that provides services to the local logical units. 
				 | 
 
			 
 
			  
				| Link station 
				 | 
 
				The part of data link control (DLC) that is responsible for the transfer of data between two communications services managers connected by a link. 
				 | 
 
			 
 
			  
				| Local server 
				 | 
 
				The machine with the SNA link to the host, where you install communications server software, to provide access to a COBOL System running on client PCs. 
				 | 
 
			 
 
			  
				| Network name (NETID) 
				 | 
 
				The name of the network to which the system is connected. 
				 | 
 
			 
 
			  
				| Logical Unit (LU) 
				 | 
 
				A network accessible unit (NAU). In SNA there are a number of logical unit types that identify the protocols supported by that logical unit. For APPC the LU type is 6.2 referred to as LU 6.2. 
				 | 
 
			 
 
			  
				| Partner LU 
				 | 
 
				The logical unit with which to communicate. 
				 | 
 
			 
 
			  
				| Transaction Program (TP) 
				 | 
 
				The program to be executed at one end of a conversation. 
				 | 
 
			 
 
			  
				| Session 
				 | 
 
				The logical connection between two network accessible units. 
				 | 
 
			 
 
			  
				| Inter Systems Communications (ISC) 
				 | 
 
				Two or more regions running on different processor complexes that are able to communicate with each other. 
				 | 
 
			 
 
			  
				| Mode 
				 | 
 
				The connection characteristics of a session.
