Protocol Specific Configuration
Terminal-Definition
Ter minal-Definition
Each 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 10300000“HDLC link 1”
Option 0000h 0008h
Term 120 1:6:3 LAPD.DLE 8080H 146AH 10300000“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 t he 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>
More specific information o n the parameters in the HDLC/LAP-D
Terminal-Definition follows.
ZLU This number (120 in the example) assigns a unique reference
number for this terminal.
