[oc] HDLC

Hi,

I have planned to implement HDLC by using the following standards;

[1] ISO/IEC 3309:1991(E), "Information Technology - Telecommunications and information exchange

between systems -High-level data link control (HDLC) procedures - Frame structure", International

Organization For Standardization, Fourth edition 1991-06-01.

[2] ISO/IEC 3309:1991/Amd.2:1992(E), "Information Technology - Telecommunications and

information exchange between systems - High-level data link control (HDLC) procedures - Frame

structure - Amendment 2: Extended transparency options for start/stop transmission", International

Organization For Standardization, 1992-01-15.

[3] ISO/IEC 4335:1991(E), "Information Technology - Telecommunications and information exchange

between systems - High-level data link control (HDLC) procedures - Elements of procedures",

International Organization For Standardization, Fourth edition 1991-09-15.

Are these the correct documents to implement the HDLC protocol?

Is there any other documents?

regards

ram.
