Hi --- I would like to run TCP-IP between a 3B2/600 and a 6386E [both under UNIX System V]. To be more specific, the two systems are about 1500 miles apart, and are interconnected by a 9600 baud private line equipped with synchronous modems at each end. Performance is not an issue at this time. I have found reference to an X.25 "spigot" for TCP-IP on the 3B2 end using the SPSC board (is this some derivative of the ISC board?) However, I've got no information yet on its companion hardware/software on the 6386E end (we do have the AT&T X.25 card for the 6386E already, along with the 3B2 ISC card). Can anyone advise, comment, or otherwise shed some light on this? Thanks in advance -- M. R. Baker AT&T-BL, Holmdel, NJ email to: hoqub!mrb (will also watch these newsgroups for replies) 201-949-7935

For instance, normally you would purchase the card and a copy of the standard distribution of our TCP/IP software, and you'd be in business if you just wanted to link 3B2's. In contrast the ISC card (Intelligent Serial Controller) provides a low level interface the X.25, as well as libraries of low level and session level system calls. The ISC card does not provide or work with our implementation of TCP/IP. It comes with several sample PADs that may or may not implement what you want to do under X.25. The SPSC and ISC are not related, and aren't very similar as far as architecture goes; the SPSC has more memory, and can run at speeds up to 64K bps with a V.35 interface, it is also orderable with an RS 232 interface (the ISC is limitted to a 19.2 RS 232 interface). AT&T OEM's the SPSC card from Advanced Computer Communications (ACC), their number is (805) 963 - 9431 (Santa Barbara, CA). They might have a version of their hardware and software for AT bus machines. As far as I know AT&T has no plans for a companion product to the SPSC on the 6386 (we do offer the X.25 interface though). -- Frank McGee, AT&T Tier 3 Indirect Channel Sales Support attmail!fmcgee
