Predefined Configuration Values
The following configuration values are currently defined for use in
HDLC/LAP-D configurationas a replacementfor t he P OLL and SELECT
address fields. These values are used (for example HDLC_DTE_3.0) as a
symbolic way of configuring the associated two 16-bit hexadecimal
values.
If a particular desired configuration v alue is not provided by these
values, then two hexadecimal values can be used i nstead (as for normal
poll and select specification).
HDLC_DTE_400MS and HDLC_DCE_400MS
N201 = 0128 bytes
T200 = 400ms K = 3 N200 = 10
Equivalent parameters
HDLC_DTE_400MS - 8080h 146Ah
HDLC_DCE_400MS - 0080h 146Ah
HDLC_DTE_3.0 and HDLC_DCE_3.0
N201 = 1024 bytes
T200 = 3.0sec K = 3, N200 = 10
Equivalent parameters
HDLC_DTE_3.0 - 8400h 4F6Ah
HDLC_DCE_3.0 - 0400h 4F6Ah
Note that specific user defined configurations may be added to the ttgen
configuration file. These should use the #define statementand be placed
at the beginning of the file. Refer to the examples in the file
