Predefined Configuration Values

The following configuration values are currently defined for use in HDLC/LAP-D configuration as a replacement for the POLL 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 value is not provided by these values, then two hexadecimal values can be used instead (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 statement and be placed at the beginning of the file. Refer to the examples in the file /opt/acc/cfg/ttgendefine.

	CAUTION: DO NOT make changes to the /opt/acc/cfg/ttgendefine file itself, since this is part of the ACC Base product software, and may be overwritten when updates to the product are applied.
