OK. Here's my situation. I've got a metallic (LADS) circuit between my house and my Internet site. I am presently running at 19.2kb with a pair of Gandalf LDS309a limited distance modems. What are my chances of ekeing any additional bandwidth out of this line, and what technology would be necessary to take advantage of it? I have seen ads for 56kb DSUs which are also claimed to work on twisted pair, but they seem to refer to in-house private twisted pair and not metallic lines from the TelCo. Just what is the theoretical and practical maximum bandwidth of a LADS circuit? -- Steve Dyer dyer@harvard.harvard.edu dyer@spdcc.COM aka {harvard,husc6,linus,ima,bbn,m2c,mipseast}!spdcc!dyer
