v.Richard Tl Posts: 6222 USA	Posted - 11/4/2000 12:01:36 PM Your rate of 26.4/28.8k is what I'd call average V.34; If you are not getting a double handshake, your setup is incorrect or you are not calling V.90-enabled modem www.808news.com/56k/trouble3.htm If you do get a double handshake, you should try calling other #s - local & toll/toll-free to isolate problem www.808news.com/56k/trouble4.htm www.808news.com/56k/trouble1.htm Aloha, Richard
jjmerchant Tl Posts: 2	Posted - 11/4/2000 5:47:18 PM I am getting a double handshake and I called many other phone numbers to no avail. Could my phone line be bad even if line test says that it is 56K compatible
v.Richard Tl Posts: 6222 USA	Posted - 11/8/2000 8:52:41 AM My guess is you are on an integrated but misconfigured or incompatible digital loop carrier (DLC) between your modem & telco office. www.808news.com/56k/coding.htm Aloha, Richard
