Software compression at the handshake level... Mppc and stac don't even enter the equation. This is a communications level problem, and unchecking 'Enable Software Compression' in the DUN settings should fix this in about 90% of cases. If the disconnect issue is a very wide-scale problem (like >40% of all calls), then you need to work with your telco to verify all the options set on every part of the circuits feeding your TNT. For example, I had this problem really bad, and after looking, it turned out to be a bad T span between the ILEC and the CLEC I had service with (the problem was on the 3rd member of a trunkgroup that handled nearly half of my traffic). -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 - 866.477.5638 > -----Original Message----- > From: akeed hartala [mailto:hartala80 at hotmail.com] > Sent: Wednesday, June 04, 2003 10:54 AM > To: troy at psknet.com; max_and_tnt at hotmail.com; > ascend-users at max.bungi.com > Subject: RE: (ASCEND) Re: disconnected users > > > Dear Troy , > For modem hanging up i doubt that it's the DSP cards problem > but i don't > know how to prove that , do u have any idea about how to > monitor the modems > performance ? > about upgrading the customer's modem firmware it's too > difficult solution on > the large scale. > for the software compression , we are using mppc over the > TNTs , i tried to > use ms-stac but i got the same result. > do u have an idea about how to trace ppp handshake and find > where exactly > the problem. > thx in advance > > > > Rgrds > Emad Anis > Data Communication Engineer > LINKdotNET > www.link.net > > > > > > >From: "Troy Settle" <troy at psknet.com> > >To: "'akeed hartala'" > ><hartala80 at hotmail.com>,<max_and_tnt at hotmail.com>,<ascend-use rs at max.bungi.com> > >Subject: RE: (ASCEND) Re: disconnected users > >Date: Wed, 4 Jun 2003 10:18:48 -0400 > > > > > >Akeed, > > > >More specifically, the 185/60 is the customer's modem > hanging up.
