INTRODUCTION
This Amendment takes into account that in the third edition of ISO/IEC 13239, frame type 3
has been added as Annex H.4, as requested by IEC TC 13 WG 14, and that second editions
of some parts of the IEC 62056 series are under preparation.
It specifies now that a secondary station may use more than one addressing scheme.
It contains some changes concerning the negotiation of the maximum information length field
HDLC parameter for better efficiency.
References have been updated and some editorial errors have also been corrected.
