Early Rockwell chipset V.34 modems did not support asymmetric connects -- it is an optional part of the standard. Take a look at bit 50 in the modulation parameter sequences (either MP0 or MP1) which is set to 1 to indicate a modem capable of asymmetric data rates.

The "Wait for Call" option isin't working. I use it for recieving fax, data and answering my calls when i am not at home. The problem with it is that when a call is recieved the program sends the message that the user is not at place and then waits for the fax transmission or to record a message for me. It recieves the fax alright but after recieving it is fails to hang up the phone. Another problem is that it is not able record the incoming messages. Hoping for help soon enough. Thnx, Timmy ... Hi!

Some protocols allow different speeds on each 'channel'. Abd it's NORMAL behavior on 56K modems, since one side is ALWAYS at 33.6 or below. --- Platinum Xpress/386/Wildcat! v1.3e * Origin: FidoNet International Coordinator Emeritus, for life (1:202/746) --------------- FIDO MESSAGE AREA==> TOPIC: 105 HIGH SPEED MODEM Ref: FA100010Date: 05/20/98 From: HENK JASPERS Time: 05:16am \/To: BILL MITCHELL (Read 4 times) Subj: USR Courier Question Hello Bill, On (18 May 98) Bill Mitchell wrote to Richard Town... BM> V.FAST became V.34 after lenghtly negociations, and it included BM> many enhancements What enhancements? I own several Rockwell based modems with both V.FC and V.34 protocols and to my own surprise I found V.FC to perform considerably better than V.34. I.e. when connecting to USA BBS's (from the Netherlands) I get 14.4 with V.FC and 12.0 with V.34. Locally V.FC also performs far more stable and at higher connect rates with a better throughput.

First v34 was symmetric Really? Can you give a source for that comment? Near as I can recall, asymmetric link speeds were part of the drafts well before the final draft. I can't remember any modems being shipped as V.34 based on earlier drafts but perhaps you can enlighten me as to which manufacturers were shipping modems based on drafts prior to the final clean draft (ITU-T temporary document 57) and describing them as V.34.

There is no requirement that both the send and receive channel at one end be at the same speed.

The remote end must receive at the speed you're sending at, and you must receive at the speed it's sending at. The receive and send speeds with V.34 can be different. So 28800/31200 is perfectly reasonable. Rick --- Msged 4.00 * Origin: The Warlock's Cave, Ottawa ON (1:163/215.39)
