Protocol Specific Configuration
Terminal-DefinitionTerminal-DefinitionEach HDLC/LAP-D Mux channel requires one (and only one) Terminal-Definition for the HDLC/LAP-D point-to-point link. The LAP-D terminal is defined by a Terminal-Definition line in the ZCOM network answer file (-.answ).
Some sample HDLC/LAP-D Terminal-Definition lines for the Z7300A card follow:
| | | | | | |
Term | 120 | 1:6:3 LAPD.DLE | HDLC_DTE_400MS | 1030 0 0 0 0 | “HDLC link 1” |
Option | 0000h | 0008h | | | |
Term | 120 | 1:6:3 LAPD.DLE | 8080H 146AH | 1030 0 0 0 0 | “HDLC link 1” |
Option | 0000h | 0008h | | | |
The first example above is a Terminal-Definition that defines an HDLC/LAP-D terminal with ZLU 120 on card 1 port 6 subchannel 3. It is configured as a DTE (user side) with frame time-out value of 400 milliseconds. The first OPTION word configures the idle line timer to the default value. The second OPTION word defines the SAPI and TEI. The second definition is the same as the first except that it uses the POLL and SELECT words to define the mode of operation. When the POLL and SELECT values are used they are specified as two 16 bit hex values.
NOTE | This is “non-standard” hexadecimal notation. |

The descriptions of the fields within these values are described below under Poll/Select/Option Configuration Values.
The Terminal-Definition takes the following format:
Term zlu mux:port:subc dtype poll select
appl_no inst_no brch_no wkst_no area_no name <option>
