Packet Assembler Disassembler
(PAD) Capabilities
The ADM options provide capabilities outlined in the CCITT X.3, X.28, and X.29
specifications. The local mode commands provide the functions analogous to
those specified in X.28. The ADM supports receipt of X.29
SET and READ parameter messages received from a remote X.25 host.
Receipt of an X.29 SET command with no parameters (defined by CCITT to
mean ‘‘load initial profile’’) causes the ADM to restore the PAD parameter values
which were active at the start of the data call.
ADM Options Relative to CCITT Recommendation X.3 Parameters: CCITT
Recommendation X.3 defines certain parameters for an X.25 PAD. The CCITT
assigns reference numbers by which these parameters are identified and assigns
different values to each parameter. The parameter values are also represented
by a number. Table 6-1 gives the parameter reference numbers and parameter
values that the ADM supports. Parameter 101 can be set via X.29, but is not an
X.3 parameter. Other ADM options that are not in this table are not X.3
parameters and are not settable or readable via X.29.
