I just had a 4-wire, full duplex leased line installed between my home and the university. There's an RJ-11 jack where the phone cord terminates and a powered box called a "Teltrend Data Station Termination" which plugs into the RJ-11 jack and provides a RJ-11 jack of its own. What does this box do and why is it necessary? In the past, I've connected leased-line modems to what looked like a simple 4-wire telco jack without any extra electronics. Also, since both ends use the same central office, I was planning to use a pair of short-haul modems to support a 19.2kb data rate (this has been successful with other installations in the past.) Could this box (or any other telco-related factor) influence this? Finally, I was going to purchase a pair of Gandalf LDS309A modems. They run about $400 a piece; can anyone suggest anything possibly cheaper which would work as well? Please reply by mail, since I'm not on the Telecom list. Thanks. --- Steve Dyer dyer@harvard.HARVARD.EDU dyer@spdcc.COM aka {linus,wanginst,bbnccv,harvard,ima,ihnp4}!spdcc!dyer
