TITLE: Information and clarification of FLUSH procedures in V.44
PROJECT: PN-xxxx
DISTRIBUTION: Members of TR-30 and TR-30.1 and meeting attendees
The V.44 source code that Hughes provided to several manufacturers does not match the FLUSH procedures in the determined version of Recommendation of V.44 in a particular instance. The purpose of this paper is to make all companies aware that the procedures for the FLUSH are correct as defined in Recommendation V.44 and that the source code did not follow the defined procedure in a specific instance. Table 5/V.44 specifically states that an ordinal output immediately following a control code shall have a code prefix of ‘0’. This is correct.
The V.44 source code provided several months ago does not conform to Table 5/V.44 in one instance. An ordinal output immediately following a FLUSH control code may, in some instances, have a code prefix of ‘00’. This is NOT correct.
New source code, with minor fixes to the V.44 encoder and decoder, to correct this non-conformity has been provided to affected companies and is available if desired.
