We are planning on connecting a remote site via 56kbps circuit between two routers. Can who ever is doing this tell me what DSU you have used to do this and any other information you think is useful? Thanks Phil Green Syracuse University

These have proven to be fairly reliable and trustworthy. As far as other information, keep the circuit vendor ID number near the phone! You never know when an outage may occur.... Thanks, Allan Leinwand

I know of two reliable and widely used 56kb CSU/DSUs. The Dowty Information Systems unit has been sucessfully used by many people for years. Several of the regional networks use them. The unit that has both an RS232 and a V.35 interface is popular and I believe is only about $695. They have a less expensive model with a V.35 only interface. Dowty can be reached at (800) 553-6989. The person to talk to is Carol Kaufman. They are in Cherry Hill N.J. , so you need to call during East Coast business hours. In the last year Teleprocessing Products came out with a 56kb CSU/DSU that looks pretty good. Someone that I talked to working in one of the large PDN's recently did an evaluation to compare this unit with the Dowty and ranked them equivalent in reliability and performance. They chose the Teleprocessing Products model, since it lists for only $500. One nice thing about the Dowtys, is that all the dip switches and loopback buttons are inside a little door that flips open on the front panel. Easier to get at then rear mounted dip switches, and the test buttons are protected from accidentally being hit. Rob
