General discussion

There is a doubt in segmented frame so you hopefully give response as i describe in below points.
1. Is there any relation between block response/request and segmented frame.

2. If meter buffer size is 2048 then only segmented frame possible ??? my meter buffer size is 512 so in this case how can be possible the segmented frame

3. In frame format i know that A0 is non segmented frame and A8 is segmented frame but if data length is long for instance A1 TO A7 is this too segmented frame or only block response/request i showing some example so that you can get easily through it.

4. i would appreciate your response.

Hi, Block and frame are two…

Hi,

Block and frame are two different things. Read PDU and frame size from here:

I propose that you get the Green Book. It will help you to understand the HDLC framing. HDLC framing is more complex than it looks but I hope this will help you.
