Message-ID: <2695@ucsfcca.ucsf.edu> Date: 3 Jan 90 22:25:07 GMT Reply-To: jst@cca.ucsf.edu (Joe Stong) Organization: Computer Center, UCSF Lines: 5 Someone I know claims that most TCP/IP packets transmitted on T1 lines are imbedded in X.25 protocol packets. Is this true, or what is actually used? Or it TCP/IP alone with maybe an alternate checksum (CRC) sufficient? Joe Stong jst@cca.ucsf.edu
